Contractor Bond Insurance 2027 Cost Calculator

Contractor bonds (license, performance, payment) cost 1-15% of bond amount annually, depending on credit score and contract size. License bonds (state-required) are cheapest; performance bonds on large public projects can require collateral. This 2027 calculator estimates premium.

Bonds Are Not Insurance — They're Credit

Despite the name "bond insurance," surety bonds work like credit: the surety guarantees your performance to a third party (state, project owner). If a claim is paid, the surety has full subrogation against you personally. You sign a General Indemnity Agreement giving the surety the right to collect everything paid. Insurance protects YOU from loss; a bond protects the OBLIGEE from loss caused by you.

The Four Bond Types Every Contractor Should Know

License/permit bond: state requires for contractor licensing — $5K-$25K bond, $50-$250/year. Bid bond: 5-10% of bid value, guarantees you'll sign the contract if awarded. Refundable. Performance bond: guarantees you'll complete the contract per specifications. Required on Miller Act public projects ($100K+) and many private projects. Payment bond: guarantees your subs and suppliers get paid. Usually issued together with performance bond at no extra cost on public projects.

How To Get The Best Rate In 2027

Credit score drives everything — clean to 720+. Working capital matters — sureties want $1 of capital per $5-$10 of bonded backlog. 3-year audited financials unlock pricing tiers; reviewed financials are minimum for serious bonding. Bonding history — first bond approval is the hardest; once you have one, future approvals are easier. Bonding agent matters — work with a true surety specialist (NASBP member), not your general P&C agent. They have markets and underwriter relationships that get tough deals approved.

Bonding Mistakes That Kill Approvals

(1) Applying with personal credit issues — under 650 credit triggers collateral requirements (often 50-100% of bond amount in cash). Repair credit before applying. (2) Mixing personal and business financials — sole proprietors are scrutinized heavily; consider LLC formation. (3) Not maintaining working capital ratio — sureties want $1 of working capital per $5-$10 of bonded backlog. Tight cash position triggers requests for additional collateral. (4) Using a generalist agent — bonding requires specialty markets and underwriter relationships. Use a NASBP-member surety agent. (5) Skipping the GIA review — General Indemnity Agreements pledge personal and business assets.
