Gas prices have surged more than 30 percent since the start of the Iran conflict in late February, and more than half of Americans now say they plan to drive less. For millions of low-mileage drivers, a growing corner of the insurance market offers a straightforward deal: pay only for the miles you actually put on the road.
As of April 28, the average cost of a gallon of regular gasoline hit $4.18, the highest level in four years, CNBC Select reported, citing AAA data. A mid-April CNBC All-America Economic Survey of 1,000 Americans found that more than 50 percent plan to cut back on travel because of the pain at the pump.
That behavioral shift has a financial ripple most people overlook: if you're already driving fewer miles, your traditional car insurance premium still charges you the same flat rate. Pay-per-mile policies flip that model. They charge a daily base rate plus a per-mile fee, typically between four and eight cents, so the less you drive, the less you pay.
Insurify, the insurance comparison platform, ran the numbers. The average driver who cuts annual mileage by 10 percent would save roughly $27 in insurance costs by year's end under a traditional policy. Switch to a pay-per-mile plan and that figure jumps to $59, more than double.
Those dollar amounts sound modest in isolation. But for households already squeezed by rising costs across the board, every recurring bill that shrinks matters. And the savings scale with behavior: the fewer miles driven, the bigger the gap between a flat-rate premium and a per-mile one.
An Insurify representative told CNBC Select by email that usage-based insurance has been building momentum for years:
"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."
One in six. That's no longer a novelty product. It's a market segment, and one that high gas prices are pushing further into the mainstream.
Three names dominate the current pay-per-mile landscape, each with a different footprint.
Nationwide SmartMiles leads on availability, operating in 44 states. Nationwide says SmartMiles customers save an average of 25 percent compared with the company's traditional auto policy, with savings reaching up to 30 percent. The program also includes a road-trip exception: it charges only for the first 250 miles driven in a single day, so a long weekend haul doesn't wreck your rate.
CNBC Select flagged SmartMiles as its preferred option for wide availability. For drivers who want to compare that against what traditional insurers are returning to customers, State Farm recently declared a record $5 billion payout to its auto insurance members, a reminder that competition for policyholders is real.
Metromile, backed by Lemonade, claims its customers save over 40 percent compared with standard auto insurance. The catch: Metromile currently offers coverage in only eight states. Mileage is tracked through a device or app, and the per-mile charge applies on top of a base daily rate.
Mile Auto takes the lowest-tech approach. It requires a photo of the odometer once a month, no transmitter, no app constantly pinging your location. Mile Auto offers liability, collision, comprehensive, and optional coverages. Its limitation is geography: it operates in only a few states.
Pay-per-mile insurance isn't for everyone. Carinsurance.com notes that drivers who travel fewer than 50 miles per day are typically the best fit. Commuters logging long highway stretches every morning may find a traditional policy cheaper.
But the profile of the ideal pay-per-mile customer is expanding. Remote workers, retirees, households with a second car that mostly sits in the driveway, city residents who rely on public transit most days, all of them pay traditional premiums that subsidize heavier drivers. Per-mile pricing corrects that imbalance.
The concept isn't new. California moved toward allowing pay-as-you-drive auto insurance years ago when Insurance Commissioner Steve Poizner released regulations permitting mileage verification for such plans. The goal then, as the New York Post reported, was to use per-mile pricing to encourage less driving while reducing air pollution, traffic congestion, and collisions. What was once a regulatory experiment has become a competitive product.
High gas prices rarely travel alone. When fuel costs spike, grocery bills follow. Delivery surcharges climb. The household budget absorbs hits from every direction. A mid-April survey showing that more than half of Americans plan to cut driving isn't just a transportation statistic, it's a cost-of-living indicator.
For Americans already rethinking where their money goes each month, insurance premiums deserve a harder look. Most people set their auto policy once a year and forget it. The current environment rewards those who don't.
Mileage tracking raises a fair question about privacy. Nationwide's SmartMiles and Metromile both use transmitters or vehicle systems to log miles. Mile Auto's odometer-photo method avoids real-time tracking, but the trade-off is less granular data and, potentially, fewer features. Drivers should weigh what they're comfortable sharing.
Vehicle choice matters too. Buyers shopping for a practical, affordable car, whether to cut fuel costs or lower premiums, should know that the vehicle itself affects what insurers charge. A cheaper, safer car paired with a per-mile policy can compound savings.
Several questions remain unanswered. Insurify's $27 and $59 savings estimates lack published methodology, it's unclear what baseline mileage, vehicle type, or regional pricing was assumed. The specific states where each provider operates aren't fully listed. And the claimed savings percentages from Nationwide and Metromile are company-reported figures, not independently audited.
None of that makes the trend less real. Usage-based insurance has doubled its market share in a decade. Gas prices just handed it another tailwind. For budget-conscious households also exploring smarter ways to manage their money, trimming a fixed monthly cost that no longer matches actual usage is common sense.
When the government can't keep fuel affordable, the least the market can do is stop charging you for miles you never drove.
