How It Works

This calculator estimates the premium for a surety or fidelity bond based on three factors: bond amount, bond type, and credit tier. The base rate is derived from industry-standard underwriting guidelines.

Formula: Annual Premium = Bond Amount x Rate (%). The rate varies by bond type and credit tier:

  • Contractor License: 1.0% to 3.0% (based on credit)
  • Commercial Surety: 0.8% to 2.5%
  • Fidelity Bond: 0.5% to 2.0%
  • Court Bond: 0.7% to 2.2%

Credit tiers adjust the rate: Excellent (0.8x base), Good (1.0x), Fair (1.3x), Poor (1.8x). The total premium is the annual premium multiplied by the term length. Minimum premium floor of $100 applies.

Example: A $50,000 contractor bond with good credit yields 1.5% rate = $750 annual premium. Over 3 years: $2,250 total.
