About this estimate. The base figure is the NAIC combined average premium for New Hampshire (liability + collision + comprehensive, 2023). The calculator applies published industry multipliers (age, credit, record, coverage) from secondary sources (Bankrate / ValuePenguin modeled rates) and is an estimate for informational purposes only — not an insurance quote or offer. Credit-tier adjustments are not applied in states that ban credit-based insurance scoring (California, Hawaii, Massachusetts, Michigan). See our full methodology.
