Performance Bond Cost: What You'll Actually Pay

On a $500,000 contract, a performance bond typically costs $2,500-$7,500 with excellent credit (0.5-1.5%), $7,500-$12,500 with good credit (1.5-2.5%), $15,000-$25,000 with fair credit (3-5%), and $25,000-$50,000 with poor credit (5-10%). The bond amount equals 100% of the contract value, so your premium is a percentage of the full $500,000.

Sureties use a sliding scale because larger contracts carry proportionally less risk per dollar. The first $100,000 might cost ~2.5%, but the next $400,000 drops to ~1.5%, and amounts over $500,000 drop to ~1% or less. This means a $5 million bond doesn't cost 10x a $500,000 bond - it's typically 3-4x. The sliding scale rewards contractors who take on bigger projects.

Performance bond premiums are typically paid upfront for the full project duration. Unlike annual bonds that renew each year, a performance bond covers one specific contract from start to finish. If the project takes 18 months, you pay once at the beginning. Some sureties offer financing options that split the premium into payments, but you'll pay a small financing charge.

The contractor pays for the performance bond, but the cost is almost always built into the bid price. When a project requires bonding, every bidder factors that premium into their total. So the owner ultimately pays for it indirectly through higher bids. On federal projects required under the Miller Act and most state public works, performance bonds are mandatory, and owners expect the cost to be included in bids.

Yes, but it costs significantly more. With credit below 620, expect to pay 5-10% of the contract value - that's $25,000-$50,000 on a $500K project. Some specialized sureties work with contractors who have credit issues, bankruptcies, or tax liens, but they'll require collateral (often 50-100% of the bond amount), strong financials, or indemnitors. Improving your credit before bidding on bonded work can save you thousands.

Your bonding capacity - the maximum total bond amount a surety will issue you - directly affects pricing. If you're using 80%+ of your capacity on one project, the surety sees higher risk and charges more. Contractors with strong net worth, liquid assets, and a track record of finishing projects on time get higher capacity limits and lower rates. A general rule: your net worth should be at least 10% of your bonding capacity.

Usually not. When a project requires both performance and payment bonds (which is standard on public works), sureties quote them as a package. The combined premium is typically 1-3% of the contract value for well-qualified contractors. Buying them together from the same surety costs less than purchasing them separately. Some sureties quote a single rate that covers both bonds.

Focus on these five areas: (1) Improve your credit score - even 50 points can cut rates significantly. (2) Build your net worth by retaining earnings in the business. (3) Maintain clean financial statements prepared by a CPA. (4) Complete projects without claims or delays to build your track record. (5) Work with a surety bond broker who shops multiple carriers for the best rate. Contractors who do all five regularly pay under 1% on their bonds.
