The average car insurance at age 25 costs $146 per month, or $1,752 per year, for full coverage with 100/300/100 liability limits. That rate is $21 per month lower than at age 24. Insurers price 25-year-olds as lower risk than teens and early-20s drivers, but your final premium still depends on your driving record, credit history and coverage level.
Rates drop sharply between ages 16 and 21, then level off by 25. At 16, full coverage averages $7,550 per year. By 21, the average falls to $2,533 per year. At 25, the average is $1,752, which is about 77% lower than at 16. Most age-based savings happen before 25, with smaller reductions each year after that.
