Frequently Asked Questions
Premium rates?
Strong contractor 0.5-1.0% of contract. Standard 1.0-2.0%. Marginal 2.0-3.5%. Distressed may be 4%+ if bonded at all. Term length adjusts pricing.
Single premium?
Usually paid upfront at bond issuance. Covers entire project term. Some sureties allow annual premium payments on multi-year projects; admin fee added.

Performance bonds are not refundable on early completion. Payment bonds similar. Cost is one-time; price into contract.
How often should I rerun this?
Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
