Construction Bond Calculator FAQs

How much does a construction bond cost?

Construction bonds typically cost 0.5% to 3% of the contract value. A $1 million project costs $5,000-$30,000 for performance and payment bonds. Our construction bond cost calculator uses sliding scale rates - larger projects get lower effective rates.

What bonds are required for construction projects?

Most public construction projects require three bonds: a bid bond (guarantees your bid), performance bond (guarantees completion), and payment bond (protects subcontractors). Federal Miller Act projects over $150,000 require all three.

What is the Miller Act bond requirement?

The Miller Act requires 100% performance bonds and 100% payment bonds for federal construction contracts exceeding $150,000. Bonds must be from Treasury-listed sureties. Use our construction bond calculator to estimate costs for Miller Act projects.
