New Hampshire Contractor License Fee Calculator
Estimate your New Hampshire contractor license fees based on license type, classification, and whether you are applying for a new license or renewing. Fees are based on RSA 310-A and the NH Office of Professional Licensure and Certification (OPLC) fee schedule.
For businesses licensing multiple individuals under one entity, enter total count.
Applicable for new applicants sitting for a trade exam (PSI/Prometric).
Formula
Grand Total = (Base Fee × N) + (Late Penalty × N) + (Exam Fee × N)
- Base Fee = License fee for the selected type and class (new or renewal rate)
- Late Penalty = max(Renewal Fee × 0.50, $25.00) per license — applies only to late renewals
- Exam Fee = $82 (trades) or $55 (general contractor) per individual — applies only when exam is selected
- N = Number of licenses / individuals
Example: A business renewing 3 Master Electrician licenses late:
Base = $75 × 3 = $225 | Late Penalty = $37.50 × 3 = $112.50 | Total = $337.50
