Performance Bonds for Contractors

What Is a Performance Bond?

A performance bond is a type of contract surety bond that provides a financial guarantee to a project owner (obligee) that the contractor (principal) will complete the construction project in full accordance with the terms, conditions, specifications, and drawings of the contract. If the contractor fails to perform — whether due to abandonment, insolvency, inability to meet specifications, or any other form of default — the surety company that issued the performance bond is obligated to step in and ensure the project is completed.

Performance bonds are one of the most important risk management tools in the construction industry. They shift the risk of contractor default from the project owner to the surety company, ensuring that the owner receives the completed project they contracted for, regardless of what happens to the contractor. Performance bonds are the cornerstone of public construction bonding and are required on virtually all federal and state public works projects in the United States.

Unlike insurance, a performance bond does not protect the contractor — it protects the project owner. The contractor remains fully liable for any losses the surety incurs as a result of the contractor's default. The surety has the right to seek full reimbursement from the contractor and any personal indemnitors under the General Indemnity Agreement (GIA) signed at the time the bond was issued.

How Do Performance Bonds Work?

Like all surety bonds, a performance bond involves a three-party relationship:

1. Principal (Contractor) — The contractor who is obligated to perform the construction work according to the contract. The principal purchases the performance bond and is the party whose performance is being guaranteed.
2. Obligee (Project Owner) — The entity that requires and is protected by the performance bond. On public projects, this is typically a government agency (federal, state, county, or municipal). On private projects, this is the property owner, developer, or lender.
3. Surety (Bonding Company) — The insurance company or surety company that issues the performance bond and guarantees the contractor's performance. If the contractor defaults, the surety is responsible for ensuring the project is completed.

The performance bond process typically works as follows:

1. A project owner requires a performance bond as a condition of the construction contract. The bond amount is typically set at 100% of the contract price.
2. The contractor applies for the performance bond through a surety bond agent or broker. The surety underwrites the contractor by evaluating their financial strength, construction experience, and overall capability to perform the work.
3. If approved, the surety issues the performance bond. The contractor pays a premium (typically 1% to 3% of the contract price) for the bond.
4. The performance bond remains in effect for the duration of the construction project, typically until the project is substantially completed and accepted by the owner.
5. If the contractor completes the project per the contract terms, the bond is exonerated and no claim is ever made.
6. If the contractor defaults, the project owner notifies the surety of the default and may make a claim on the performance bond.

What Happens When the Contractor Defaults?

When a contractor defaults on a bonded project, the surety has several options for resolving the situation. The surety will investigate the claim, and if the default is valid, the surety typically chooses one of the following courses of action:

1. Finance the original contractor — If the surety determines that the contractor can still complete the project with additional financial support, the surety may provide financing, management assistance, or other resources to help the contractor finish the work. This is often the surety's preferred option because it tends to be the least costly resolution.
2. Hire a completing contractor — The surety selects and hires a new contractor to complete the remaining work on the project. The surety manages the completion process and bears the cost of finishing the project, up to the penal sum of the bond.
3. Tender the project back to the obligee — In some cases, the surety may tender (offer) the obligation back to the project owner, allowing the owner to select a replacement contractor. The surety then reimburses the owner for the additional cost of completion, up to the penal sum.
4. Pay the bond penalty — The surety pays the project owner the penal sum of the bond (or the actual damages, whichever is less), allowing the owner to arrange for completion of the work independently.

Regardless of which option the surety chooses, the contractor (principal) remains liable to the surety for all costs incurred. The surety will pursue recovery from the contractor and any personal indemnitors under the General Indemnity Agreement.

Who Needs a Performance Bond?

Performance bonds are required in a wide range of construction scenarios:

• Federal construction projects — The Miller Act (40 U.S.C. §§ 3131–3134) requires both a performance bond and a payment bond on all federal construction contracts exceeding $150,000. This applies to all construction, alteration, or repair of any public building or public work of the United States.
• State and municipal projects — Every state has a Little Miller Act that requires performance bonds on state-funded public construction projects. The threshold amounts vary by state — some states require bonding on projects as low as $25,000, while others set the threshold at $100,000 or higher.
• Private construction projects — While not legally required, many private project owners, developers, and lenders require performance bonds on larger construction projects to protect their investment. Banks and financial institutions that finance construction often mandate performance bonds as a condition of the construction loan.
• General contractors — GCs working on bonded public or private projects must provide performance bonds as a condition of the contract.
• Subcontractors — General contractors frequently require their subcontractors to furnish performance bonds, especially on larger or more complex projects. This protects the GC from subcontractor default, which could jeopardize the entire project.
• Design-build contractors — Design-build firms are often required to furnish performance bonds covering both the design and construction phases of the project.

Performance Bond Amounts

Performance bonds are typically issued for 100% of the contract price. This means the penal sum (face value) of the bond equals the full value of the construction contract. For example:

• A $500,000 construction contract would require a performance bond with a $500,000 penal sum.
• A $5,000,000 construction contract would require a performance bond with a $5,000,000 penal sum.
• A $25,000,000 construction contract would require a performance bond with a $25,000,000 penal sum.

On public projects governed by the Miller Act or state Little Miller Acts, 100% performance bonds are the standard requirement. Some private project owners may accept performance bonds for less than 100% of the contract price (such as 50%), though this is less common. The bond amount may also be adjusted during the project if the contract price increases due to change orders.

It is important to understand that the penal sum represents the maximum amount the surety will pay in the event of a default — it does not mean the surety will automatically pay the full penal sum. The surety's liability is limited to the actual cost of completing the project or the penal sum, whichever is less.

How Much Do Performance Bonds Cost?

The cost of a performance bond (the premium) is based on a percentage of the contract price and varies depending on the contractor's qualifications. Here are the general ranges:

• 1% to 3% of the contract price — For well-qualified contractors with strong financial statements, good credit (700+ score), and a solid track record of completing similar projects. This is the standard rate range for most established contractors.
• 3% to 5% of the contract price — For contractors with moderate risk factors, such as limited experience in the project type being bonded, weaker financial statements, or credit scores in the 600–680 range.
• 5% to 15% of the contract price — For high-risk contractors with significant credit issues, limited experience, financial challenges, or prior bond claims. Specialty sureties and the SBA program may issue bonds at these higher rates when standard sureties decline.

Performance bonds and payment bonds are almost always issued together as a package, and the combined premium covers both bonds. The rates quoted above typically represent the combined cost for both the performance bond and the payment bond. For example, a contractor paying a 2% rate on a $1,000,000 contract would pay a combined premium of $20,000 for both the performance bond and the payment bond.

Many surety companies use a sliding scale rate structure, where the rate per thousand decreases as the contract amount increases. This means that larger contracts may have a lower effective rate percentage than smaller contracts.

How to Qualify for a Performance Bond: The Three Cs

Surety underwriting for performance bonds is rigorous because the surety is guaranteeing that the contractor will complete an entire construction project. Sureties evaluate contractors using the "Three Cs" of surety underwriting:

1. Character

Character refers to the contractor's integrity, reputation, and trustworthiness. Sureties assess character through:

• Personal credit score — Sureties review the personal credit of the business owner(s) and any individual indemnitors. A score of 680 or higher is generally preferred, with scores of 700+ receiving the best rates and highest bonding capacity. Some specialty sureties will work with scores in the low 600s if other factors are strong.
• Business credit history — Payment history with suppliers, subcontractors, and lenders. Consistent on-time payment demonstrates reliability.
• Industry reputation — References from project owners, architects, engineers, subcontractors, and suppliers who can attest to the contractor's professionalism and reliability.
• Legal and claims history — Any history of lawsuits, mechanic's liens, judgments, bankruptcies, prior bond claims, or criminal matters may negatively affect qualification.

2. Capacity

Capacity refers to the contractor's technical ability and organizational resources to complete the project. Sureties evaluate:

• Construction experience — A proven track record of successfully completing projects similar in size, scope, and type to the project being bonded. A contractor experienced in $1 million commercial buildings may not qualify to bond a $10 million highway project without relevant experience.
• Key personnel — The qualifications and experience of project managers, superintendents, estimators, and other key team members. The surety wants to know that experienced people will be managing the project.
• Equipment and resources — Adequate owned or leased equipment, established relationships with qualified subcontractors, and sufficient labor resources.
• Work program (backlog) — The surety carefully evaluates the contractor's current work-in-progress schedule to ensure they are not overextended. Taking on more work than the contractor can manage is one of the leading causes of contractor failure. The surety will review the contractor's aggregate program (total of all bonded and unbonded work) to ensure capacity exists for the new project.

3. Capital

Capital refers to the contractor's financial strength and ability to fund the project's cash flow requirements. Sureties analyze:

• Financial statements — Business financial statements (balance sheet, income statement, statement of cash flows) are the foundation of surety underwriting. The level of financial documentation required scales with bond size — for bonds under $1 million, many sureties offer credit-only programs requiring no business financials. For bonds up to approximately $3 million, internal financials or a CPA compilation are often sufficient. For larger bonds, CPA-reviewed or audited financial statements are typically required. See the tier breakdown below for details.
• Working capital — Current assets minus current liabilities. Sureties want to see positive working capital sufficient to fund the project's cash flow needs. A general guideline is that working capital should be at least 10% to 15% of the contractor's largest single project and their total bonded backlog.
• Net worth — Total assets minus total liabilities. Strong net worth demonstrates long-term financial stability and the contractor's ability to absorb project losses without becoming insolvent.
• Bank line of credit — Access to bank financing provides a critical cash flow safety net and demonstrates that a financial institution has also underwritten the contractor.
• Personal financial statement — The surety requires personal financial statements from the business owner(s), as they will be signing a General Indemnity Agreement that creates personal liability for any bond losses.

What You'll Need: Underwriting Requirements by Bond Size

One of the most common questions contractors ask is: "What do I need to get bonded?" The answer depends largely on the size of the bond. While every surety has its own underwriting guidelines, the following tiers represent the general industry standards. These are rules of thumb — bonding is highly subjective, and an experienced surety agent can often find solutions outside these general parameters.

Bonds Under $1 Million — Credit-Only Programs

For bond needs under $1 million, many sureties offer credit-only programs that require no business financial statements. If you have good personal credit — typically a score of 680 or higher — you may qualify based on your credit profile alone, along with a simple application. This is the fastest and easiest path to getting bonded, and it's how many contractors get started in the bonded construction market.

• What you'll need: Personal credit check, completed bond application, and basic business information
• Turnaround: Often same-day or next-day approval
• Best for: Smaller projects, new contractors with good credit, subcontractors moving into bonded work

Bonds From $1 Million to ~$3 Million — Internal Financials or CPA Compilation

As bond sizes increase into the $1 million to $3 million range, sureties need to see your company's financial picture. At this level, internally prepared (in-house) financial statements or a CPA compilation are generally acceptable — you don't necessarily need CPA-reviewed statements yet. The surety will focus on your working capital (current assets minus current liabilities) and net worth (total assets minus total liabilities) to determine whether your balance sheet can support the project.

• What you'll need: In-house balance sheet and income statement or CPA-compiled financials, personal financial statement, bank reference, and work-in-progress schedule
• Key metrics: Adequate working capital (generally 10-15% of the bond amount) and positive net worth
• Best for: Growing contractors with solid financials who aren't yet at the CPA-reviewed stage

Bonds Over $3 Million — CPA-Reviewed Financials

For bonds exceeding approximately $3 million, sureties typically require CPA-reviewed financial statements prepared on a percentage-of-completion (POC) basis. This accounting method recognizes revenue and costs as work is performed rather than when the project is completed, giving the surety a real-time picture of your financial health across all active projects. You will also need to provide open and closed job schedules — detailed work-in-progress reports that show each project's contract value, costs incurred, estimated costs to complete, and projected profit or loss.

• What you'll need: CPA-reviewed financials on a POC basis, open and closed job schedules, personal financial statement, bank reference, and organizational documents
• Why POC matters: Percentage-of-completion accounting prevents a contractor from appearing profitable on paper while actually losing money on active projects. Sureties rely on this method to assess true financial health.
• Moving higher: For the largest bonding programs ($10 million+ aggregate), sureties may require CPA-audited financial statements, which carry the highest level of assurance

Credit Challenges? The SBA Bond Guarantee Program

If your credit isn't strong enough for a standard credit-only or conventional program, the SBA Surety Bond Guarantee Program provides a pathway for contractors who might otherwise be unable to get bonded. The SBA guarantees up to 90% of the surety's loss, which encourages sureties to extend bonding to contractors with limited track records, weaker credit, or smaller balance sheets.

• QuickApp process: Streamlined approval for bonds up to $500,000 — ideal for contractors with credit challenges who need to get started
• Full SBA review: For larger bonds, the SBA can guarantee bonds up to $9 million per project ($14 million on federal contracts)
• Best for: New contractors, contractors recovering from financial setbacks, and minority-, women-, and veteran-owned businesses

Important: These are general guidelines, not absolute requirements. Surety underwriting is highly individualized — your construction experience, project type, relationship history, and many other factors influence the decision.

What Triggers a Performance Bond Claim?

A performance bond claim occurs when the contractor fails to fulfill their contractual obligations. The most common triggers for a performance bond claim include:

• Contractor abandons the project — The contractor walks away from the job site and ceases work, leaving the project incomplete. This is the most straightforward type of default.
• Failure to meet contract specifications — The contractor's work does not conform to the plans, specifications, or quality standards required by the contract, and the contractor refuses or is unable to correct the deficiencies.
• Contractor becomes insolvent or files bankruptcy — When a contractor can no longer meet their financial obligations, they may be unable to complete the project. Bankruptcy often triggers an automatic default under the contract and the bond.
• Persistent schedule delays — The contractor falls significantly behind the contractual schedule and demonstrates an inability to recover, jeopardizing the project's completion date.
• Failure to pay subcontractors and suppliers — While non-payment is technically a payment bond issue, chronic non-payment can lead subcontractors and suppliers to stop working, which causes the project to stall and may trigger a performance bond default.
• Failure to comply with safety, environmental, or legal requirements — Violations that result in work stoppages, orders to cease and desist, or revocation of permits can constitute a default under the contract.
• Termination for cause by the project owner — The project owner formally terminates the contractor for cause under the contract's termination provisions, triggering the performance bond.

The Performance Bond Claim Process: Step by Step

The performance bond claim process is more complex than other types of surety bond claims because the surety must evaluate the project and determine the best course of action for completion. Here is how the process typically unfolds:

1. Notice of default — The project owner provides written notice to the contractor that they are in default of the contract. Most construction contracts and performance bond forms require the obligee to provide formal notice of default before terminating the contractor or making a bond claim. The surety should also be notified at this stage.
2. Opportunity to cure — Many contracts and bond forms provide the contractor with a period of time (typically 7 to 15 days) to cure the default before the owner can terminate. This gives the contractor a final chance to resume work or correct deficiencies.
3. Termination for cause — If the contractor fails to cure the default within the specified timeframe, the project owner formally terminates the contractor for cause under the contract. The termination notice should reference both the contract provisions and the performance bond.
4. Formal claim to the surety — The project owner submits a written claim to the surety, providing documentation including the contract, performance bond, notice of default, termination letter, evidence of the default, the current status of the project, and an estimate of the cost to complete the remaining work.
5. Surety investigation — The surety conducts a thorough investigation of the claim. This typically includes inspecting the project site, reviewing the contract documents and project records, interviewing the parties involved, and assessing the cost to complete the project. The surety may engage independent engineers, accountants, and construction consultants.
6. Surety's response and election — After investigating, the surety determines its course of action. Under most modern performance bond forms (such as the AIA A312 Performance Bond), the surety must respond within a specified timeframe and elect one of its options: finance the contractor, hire a replacement, tender the obligation to the owner, or deny the claim if it determines the default is not valid.
7. Project completion — Depending on the option selected, the surety oversees or funds the completion of the project. If the surety hires a completing contractor, the surety manages the procurement process and the completion work.
8. Final accounting and indemnification — After the project is completed, the surety conducts a final accounting of all costs incurred. The surety then exercises its right of indemnification against the original contractor and any personal indemnitors, seeking full reimbursement for the claim payment plus investigation and administration costs.

Performance Bond vs. Payment Bond

Performance bonds and payment bonds are the two primary types of contract surety bonds, and they are almost always required together on public construction projects. While they are often issued as a package, they serve very different purposes:

On public projects, the payment bond serves as the substitute for mechanic's lien rights, since subcontractors and suppliers cannot file mechanic's liens against government-owned property. The payment bond ensures that all parties who furnish labor and materials on the project have a remedy for non-payment.

Tips for Contractors: How to Improve Your Bondability

Qualifying for a performance bond — and increasing your bonding capacity over time — requires a focused effort across financial management, credit, and business operations. Here are proven strategies to strengthen your bonding profile:

1. Maintain strong personal and business credit — Pay all obligations on time, keep credit utilization low, and resolve any derogatory items on your credit report. A credit score of 700 or higher opens the door to the best rates and highest capacity.
2. Invest in quality financial statements — As your business grows, upgrade from compiled to reviewed, and eventually to CPA-audited financial statements. Audited statements provide the highest level of credibility to sureties and unlock the largest bonding capacity.
3. Build working capital — Retained earnings are the primary driver of working capital growth. Avoid excessive owner distributions that drain working capital. Keep enough liquidity to fund 10% to 15% of your largest single project and total bonded program.
4. Grow incrementally — Take on progressively larger projects rather than jumping to projects significantly larger than your track record supports. Sureties are comfortable with contractors who grow at a rate of 20% to 30% per year.
5. Maintain a strong bank relationship — A bank line of credit demonstrates that a financial institution has also underwritten your business. Draw on the line only when necessary and maintain a positive relationship with your banker.
6. Keep an accurate work-in-progress (WIP) schedule — Sureties use the WIP schedule to evaluate your current backlog and the profitability of your active projects. Accurately report the percentage of completion, costs to complete, and projected profit or loss on each project.
7. Avoid problem projects — A history of project losses, disputes, or claims significantly damages your bonding profile. Carefully estimate projects, manage change orders proactively, and document everything.
8. Establish a relationship with a knowledgeable surety bond agent — A specialized surety bond agent or broker who understands construction and surety underwriting can present your account effectively to the right sureties. The agent's relationship with the surety and their ability to advocate for your company makes a meaningful difference.
9. File taxes on time and keep clean records — Late tax filings and sloppy accounting are red flags for sureties. Maintain organized financial records, file all tax returns on time, and address any outstanding tax liabilities promptly.
10. Complete projects on time and within budget — The best indicator of future performance is past performance. A track record of on-time, on-budget project completions is the most powerful tool in your bonding arsenal.
