The Mathematical Foundation of Bond Pricing
While the fundamental equation appears simple—Premium = Rate × Bond Amount—determining that rate involves complex underwriting processes and sliding scale structures.
Industry Standard Sliding Scale Example
Class B General Construction Bonds:
- First $100,000: $25 per thousand (2.5%)
- Next $400,000: $15 per thousand (1.5%)
- Above $500,000: $10 per thousand (1.0%)
Example: A $750,000 contract produces an $11,000 premium—an effective rate of 1.47%, demonstrating economies of scale for larger bonds.
Credit Scores Drive Pricing Differentiation

The Three Cs Framework Guides Underwriting
Character
Integrity assessment through credit history, legal compliance, and industry reputation. Bankruptcies create 7-10 year impact on bonding availability.
Capacity
Technical expertise, project management capabilities, and organizational depth. Class A trades pay 20-50% more than Class B construction.
Capital
Financial strength through working capital, net worth, and cash flow. The "10% Rule" requires equity equal to 10% of active projects.
Bond Types Create Distinct Pricing Tiers
Contract Bonds (Construction)
- Most complex pricing with sliding scales
- Performance & payment bonds: 0.5-4% of contract
- Class A trades pay 20-50% premium over Class B
- Design-build adds 20-50% surcharge
Commercial License Bonds
- Widest pricing spreads based on credit
- Auto dealer bonds: 0.5-10% annually
- Same $25K bond: $125-$2,500 range
- Instant 1% rates available for good credit
Court Bonds: Most Competitive Pricing
Probate bonds typically cost 0.5-1% annually—half the rate of comparable commercial bonds due to lower historical loss ratios. Appeal bonds vary dramatically: cash-secured (0.3-2%) vs. real estate-secured (up to 4%).

How much does a $100,000 surety bond cost?

Use our construction bond calculator above to get accurate pricing for $100,000 bonds with your specific credit profile and bond type.
How accurate is a surety bond premium calculator?
Our surety bond premium calculator provides estimates within 10-20% of final pricing for most applicants. Actual costs depend on detailed underwriting including full credit reports, financial statements, and bond-specific risk factors. The bid bond calculator, performance bond cost calculator, and contractor license bond calculator all use industry-standard rate structures from A- minimum rated carriers. For exact pricing, request a formal quote after using our surety bond rate calculator.
What's the difference between a bid bond calculator and performance bond cost calculator?
A bid bond calculator typically shows $0 cost since bid bonds are often provided free with a bonding program. The performance bond cost calculator uses sliding scale rates (typically $25 per $1,000 for first $100K, decreasing for larger amounts). Construction bond calculators combine both—the bid bond secures your bid, then converts to a performance bond at contract award. Use our bond insurance calculator to see estimated costs for both bid and performance bonds on your project.
