Payment bond cost depends on the contract size and the surety company's assessment of risk
A payment bond is insurance that guarantees a contractor will pay their suppliers and workers. The cost is a percentage of the total contract value, typically between 0.5% and 3%, though it can run higher for riskier projects. A $100,000 contract might cost $500 to $3,000 in bond premium. The exact rate depends on the contractor's credit history, experience, the project type, and the surety company's underwriting standards.
Payment bonds are required on many public construction projects—federal law mandates them on projects over $150,000, and most states require them on public work above lower thresholds. Private projects sometimes require them too, depending on the contract language. The cost is usually paid upfront by the contractor, though some surety companies allow payment plans.
Key Takeaways
- Payment bond premiums run 0.5% to 3% of the contract value, so a $50,000 job costs $250 to $1,500 in bond premium.
- The surety company sets the rate based on the contractor's credit score, past projects, financial statements, and the type of work being bonded.
- Federal projects over $150,000 require payment bonds by law; state and local thresholds vary, and private owners can demand them regardless.
- The contractor pays the premium, not the project owner, though the cost is often factored into the bid price.
- A claim against a payment bond can take months to resolve and may require the claimant to prove non-payment in writing.
How surety companies calculate the premium rate
Surety underwriters review the contractor's financial health, track record, and the project details before quoting a rate. They pull credit reports, request tax returns and bank statements, and check the contractor's history with past bonds. A contractor with strong financials and a clean claims history pays less—often 0.5% to 1%. A newer or riskier contractor pays more, sometimes 2% to 3% or higher.
The type of work also matters. General construction is standard risk. Specialty trades like electrical or plumbing may cost slightly more. Demolition, hazardous material removal, or work in remote areas can push rates up. The project location and timeline factor in too—a tight schedule or unfamiliar jurisdiction increases perceived risk.
Surety companies also consider the project owner's payment history and the contract terms. If the owner has a reputation for withholding payment or disputing invoices, the surety may charge more or decline to bond the work entirely.
What happens when you file a claim
If a contractor fails to pay suppliers or workers, the unpaid party can file a claim against the payment bond. The claimant must notify the surety in writing, usually within a set window (often 90 days from the last work date, though this varies by bond type and state law). The notification should include proof of non-payment: invoices, delivery receipts, timesheets, and correspondence with the contractor.
The surety then investigates. They contact the contractor, request their records, and verify the work was actually performed and not paid. If the claim is valid, the surety pays the claimant up to the bond limit (usually the full contract value). If the contractor disputes the claim or the surety denies it, the claimant may need to pursue the matter in court, which can take months or years.
The contractor remains liable to the surety for the full payout. If the surety pays a claim, they can sue the contractor to recover the money, and the contractor's credit and bonding history suffer permanently.
Difference between payment bonds and performance bonds
A performance bond guarantees the contractor will complete the work as specified. A payment bond guarantees payment to suppliers and workers. They are separate instruments, though they often come as a package on public projects. Performance bonds typically cost the same or slightly less than payment bonds—both run 0.5% to 3% of contract value. Some surety companies offer a combined rate if you buy both at once.
On federal projects, the Miller Act requires both bonds. Most state prevailing wage laws require both as well. Private owners may ask for only one or the other, depending on their priorities. A performance bond protects the owner if work stops or quality fails. A payment bond protects suppliers and workers if the contractor runs out of money.
When payment bonds are required by law
Federal law (the Miller Act) requires payment and performance bonds on all federal construction contracts over $150,000. The bonds must cover 100% of the contract price. States have their own thresholds—some require bonds on public work over $50,000, others over $100,000 or $250,000. A few states require bonds on all public construction regardless of size.
Private projects are not subject to these laws, but the contract may require bonds anyway. Owners, lenders, or general contractors often demand payment bonds as a condition of the deal. If the contract says "payment bond required," the contractor must obtain one or breach the agreement.
Check your state's construction law and the specific contract language to know whether a bond is mandatory. If you are unsure, ask the project owner or your surety company.
How to get a payment bond and what to expect
Contact a surety company or a broker who places bonds. Provide the contract details: project name, location, owner, contract value, and start and end dates. The surety will ask for financial documents—usually the last two years of tax returns, current balance sheet, and bank statements. They may also request references from past clients or lenders.
Underwriting typically takes three to five business days. The surety quotes a premium rate and issues the bond if you accept. You pay the premium upfront (some companies allow monthly installments for large contracts). The bond is then delivered to the project owner or their representative, usually as a PDF or printed document.
Keep the bond on file for the duration of the project. If a claim is filed, the surety will contact you immediately. Respond promptly with documentation of payment—invoices marked paid, cancelled checks, or bank transfer records. The faster you provide proof, the faster the surety can close the claim.
Factors that increase or decrease bond cost
| Factor | Effect on Cost |
|---|---|
| Strong credit score (700+) | Lowers rate; surety sees lower risk |
| Weak credit score (below 650) | Raises rate or may disqualify contractor |
| Years in business (10+ years) | Lowers rate; track record reduces risk |
| New contractor (under 2 years) | Raises rate; limited history |
| Past bond claims | Raises rate significantly or disqualifies |
| Large liquid assets relative to contract | Lowers rate; contractor can self-fund |
| High debt-to-equity ratio | Raises rate; contractor is overleveraged |
| Specialty or hazardous work | Raises rate; higher perceived risk |
| Tight project timeline | Raises rate; less time to recover if problems arise |
Frequently Asked Questions
Can I get a payment bond if I have bad credit?
It is harder but not impossible. Surety companies will charge a higher premium—sometimes 2% to 4% or more. You may need to provide additional collateral, a personal may provide, or a co-signer with stronger credit. Some sureties will decline outright if your score is very low or you have recent defaults. Shop multiple surety companies; underwriting standards vary.
Who pays for the payment bond—me or the project owner?
The contractor pays the premium. However, contractors typically factor the bond cost into their bid price, so the owner indirectly bears the expense. On public projects, the bid usually includes the bond cost as a line item. On private work, it may be hidden in the overall price.
What is the maximum amount a payment bond will cover?
The bond limit is typically 100% of the contract value. If the contract is $200,000, the bond covers up to $200,000 in claims. Some bonds have lower limits—check your bond document. If claims exceed the limit, claimants may have to split the payout or pursue the contractor directly for the shortfall.
How long does a payment bond claim take to resolve?
Simple, undisputed claims can be paid within 30 to 60 days if documentation is complete. Disputed claims or those requiring investigation can take three to six months or longer. If the contractor contests the claim or the surety denies it, resolution may require court action, which adds months or years.
Do I need a payment bond if the contract is under the legal threshold?
Not by law, but the contract may require one anyway. Check the contract language. If it says "payment bond required," you must obtain one or breach the agreement. If there is no requirement, you can skip it, though the owner may refuse to sign without one.
