Driving less due to high gas prices? Pay-per-mile car insurance could help you save even more

Gas prices have surged more than 30% after the start of the Iran war in late February. In fact, as of April 28, the average cost for a gallon of regular gasoline was $4.18, its highest level in four years, according to AAA. The price jump is causing many to adjust their habits: More than 50% of Americans plan to travel less due to the high gas prices, according to the CNBC All-America Economic Survey of 1,000 Americans conducted in mid-April. But driving less isn't going to lower the price of your standard car insurance policy. Data from the insurance comparison shopping site Insurify found that the average driver would save $27 in insurance costs by the end of the year if they cut their total annual mileage by 10%. However, that amount jumps to $59 if drivers switch to pay-per-mile insurance. Pay-per-mile car insurance bases your premiums more directly on how much you drive. This kind of coverage charges a daily base rate and then a few cents per mile. What's more, these policies are becoming increasingly common. "The popularity of usage-based insurance policies, which includes pay-per-mile, has roughly doubled since 2016, with about one in six policyholders now using such programs," an Insurify representative told CNBC Select by email.
