Cheapest Car Insurance in New Hampshire

New Hampshire has fewer accidents per licensed driver than most states, which keeps rates lower than the national average. Drivers who skip coverage accept full personal financial liability under the state's optional-insurance law, so the insured market skews toward people who have chosen to protect themselves. That reduces claims costs statewide. MoneyGeek's average cost of car insurance in New Hampshire data shows full coverage averages $82/month in the state, $41 below the national average of $123/month.

New Hampshire also benefits from a competitive regional market. MMG, Safety Insurance, Vermont Mutual, and Mapfre Insurance all file rates aggressively in the state, which pushes national carriers to compete on price rather than brand recognition.

Full coverage in New Hampshire averages $82/month. Minimum coverage averages $43/month. That's a $39/month gap ($468/year). For MMG specifically, it's $28/month ($32/month minimum vs. $60/month full). MoneyGeek's guide on how much car insurance you need walks through this tradeoff in detail, but for most New Hampshire drivers the decision comes down to vehicle value. If your car is worth less than $4,700, the $468 annual cost of full coverage exceeds 10% of the vehicle's value, the threshold where most financial advisors recommend dropping to minimum. If your car is worth more than that, or if a lender requires full coverage, keep it.

New Hampshire's wildlife risk adds a separate factor. New Hampshire Fish and Game recorded 45 moose-vehicle collisions in 2023, with a five-year average of 68 per year. Moose strikes peak from May through October when animals move onto roads for salt residue. Comprehensive coverage pays for animal collisions. Minimum coverage does not. Drivers in northern or rural New Hampshire should keep comprehensive coverage, since a single moose strike can cost thousands in vehicle damage that minimum coverage won't pay.

New Hampshire's family policy market moves through three providers from 16 to 25. Auto-Owners leads at 16 for both genders. MMG Insurance takes over from 17 for female drivers through 20, and from 18 for male drivers through 24. Mapfre Insurance leads female drivers from 21 at a flat $107/month through 25. Families with female drivers should get a Mapfre quote at age 21. The rate drops $54/month ($648/year) from MMG's $161/month at 20 to Mapfre's $107/month at 21. Mapfre files a single rate for this age cohort rather than adjusting year by year, which is why its pricing stays flat from 21 to 25.

New Hampshire seniors pay $83 per month with Vermont Mutual Insurance, $2 less than GEICO at $85. Vermont Mutual prices seniors competitively because it serves a long-tenured New England customer base where drivers file fewer claims than at national carriers. MMG, which leads the general adult market at $60 per month, rises to $99 for seniors, $16 above Vermont Mutual.

Retired drivers whose mileage has dropped should ask Vermont Mutual about a low-mileage discount before switching carriers. That single adjustment can produce a lower rate than moving to a competitor, a pattern MoneyGeek's analysis of the cheapest car insurance for seniors confirms holds across regional New England insurers.

Safety Insurance charges $70/month after a speeding ticket in New Hampshire, the same as its clean-record rate. The spread from Safety at $70/month to fifth place (Auto-Owners at $85/month) is $15/month. Safety's rate equivalence between clean and speeding-ticket profiles makes it the default starting point after a first conviction.

Vermont Mutual Insurance charges $70/month after a first at-fault accident in New Hampshire, the same as its clean-record rate. That tolerance doesn't extend to a DUI. Vermont Mutual's DUI rate is $259/month, the highest in MoneyGeek's New Hampshire data and $68/month above the next most expensive carrier. If there's any possibility of a DUI on your record, Vermont Mutual is the wrong carrier. Mapfre Insurance at $80/month is second for at-fault accidents.

Progressive charges $89/month after a DUI in New Hampshire, the lowest rate in MoneyGeek's New Hampshire data. The next cheapest is MMG Insurance at $100/month. Vermont Mutual, which charges $70/month after an at-fault accident, charges $259/month after a DUI. A driver who chose Vermont Mutual for its at-fault accident rate should re-shop immediately after a DUI conviction.

New Hampshire requires an SR-22 filing for a minimum of three years after a first DUI conviction, per the NH Division of Motor Vehicles. The DUI stays on your driving record for 10 years. Progressive files SR-22 certificates directly with the state, so if you purchase a policy, Progressive submits the filing on your behalf.

MMG Insurance charges $66/month after a texting while driving violation in New Hampshire, a $6/month increase from its clean-record rate of $60/month. Safety Insurance at $70/month is second. The spread from MMG at $66/month to fifth place (Progressive at $95/month) is $29/month.

Mapfre Insurance charges $98/month for drivers with poor credit in New Hampshire, $19/month below Safety Insurance at $117/month. Mapfre's poor-credit rate is 40% above its good-credit rate of $70/month. That 40% increase is among the lowest credit penalties in MoneyGeek's New Hampshire data. For comparison, Nationwide charges $238/month for poor credit, 143% above its good-credit rate. Mapfre prices credit risk conservatively compared to national carriers, which makes it the right starting point if your credit is poor.

New Hampshire allows insurers to use your credit history to set premiums. California, Hawaii, Massachusetts, and Michigan ban credit as a rating factor. New Hampshire does not. Drivers with poor credit who improve their score should re-quote every 12 months. The savings don't apply automatically when your credit improves.
