How Much Is Car Insurance in Idaho? Rates by Coverage Level, Age, Driving History and Location

The average cost of full coverage car insurance in Idaho is $745 per year, considerably cheaper than the national average of $1,424 per year. Since this rate is for a 40-year-old sample driver, your costs may be lower or higher due to factors like age, driving history, coverage level, credit score and location.


Based on MoneyGeek’s findings, our sample driver — a 40-year-old with a clean record who wants a full coverage policy — will have to pay around $745 in annual premiums. However, if the driver decides to get only the state minimum policy, the average cost will be just $424 per year. However, a 16-year-old purchasing full coverage will pay an average of $2,274 annually. These are just a couple of scenarios that show how the rates change when we add variables to the calculation.
