If you barely drive, you are quietly paying for someone else’s commute. Traditional auto policies assume you put 12,000 miles a year on a car. A retiree who drives 4,000 a year and a remote worker who drives 5,000 are both subsidizing the daily drivers.

Pay-per-mile car insurance flips that. You pay a small base rate plus a few cents per mile, and the bill reflects how much you actually drive.

This guide breaks down how pay-per-mile car insurance works in 2026, who runs the major programs, where each is available, and how to tell whether the math actually works for you.

The Quick Read on Pay-Per-Mile Car Insurance

Pay-per-mile is a usage-based insurance variation, sometimes labeled Pay-As-You-Drive or Distance-Based Insurance. The NAIC’s telematics topic page lays out the simple idea: usage-based policies tie premium more closely to actual driving behavior, instead of relying only on aggregated rating factors like age, ZIP code, and credit.

The structure is consistent across programs:

1. You pick standard coverage. Liability, collision, comprehensive, uninsured-motorist, medical payments. Same coverage choices as a traditional policy, per Allstate’s pay-per-mile resource page.
2. You pay a flat daily or monthly base rate. This keeps the vehicle covered even on days you do not drive.
3. Your mileage gets tracked. Carriers use either a plug-in telematics device in the OBD-II port or a smartphone app, per Allstate’s resource page.
4. You pay a per-mile rate for each mile you drive. That stacks on top of the base.

The math is friendly for low-mileage drivers. The math turns ugly fast for daily commuters. The NAIC notes that pay-per-mile and similar UBI programs “have the advantage of utilizing individual and current driving behaviors, rather than relying on aggregated statistics and driving records that are based on past trends and events,” per the NAIC telematics page.

WHEN PAY-PER-MILE TENDS TO BEAT TRADITIONAL	WHEN IT TENDS TO COST MORE
You drive under 10,000 miles a year	You commute long distances daily
You work from home or hybrid	You frequently take long road trips
You have an extra vehicle that rarely moves	You drive for rideshare or delivery
You rely on transit, biking, or walking	You haul kids or a family across town daily
You are retired and drive locally	You live rural with no transit option

The Story Most Drivers Miss

Drivers tend to underestimate their own mileage. The Insurance Information Institute notes that insurers typically ask drivers to estimate annual miles when they apply, then check in periodically. Many drivers underestimate.

Some overestimate. The same fuzziness applies to safe driving behavior. Pay-per-mile cuts through that fuzziness with a meter.

That matters because mileage and crash risk are tightly linked. The NAIC cites research showing UBI programs reduce crash risk by around 50%, per its telematics issue brief. The Insurance Research Council’s 2022 study, summarized by the III, found 45% of drivers in a telematics program made significant safety-related changes in how they drove.

Another 35% made small changes. Roughly one in four drivers reported the changes felt permanent.

That is not a marketing claim. That is research from an industry-funded but independent insurance group, sitting on the policy-side records of how drivers actually behave under a meter.

The Major Pay-Per-Mile Programs in 2026

Two carriers operate the largest pay-per-mile programs in the United States. A small handful of smaller insurers also play in the category. Below is what each program publicly discloses about how it prices and where it operates.

Allstate Milewise

Allstate Milewise charges a low daily rate plus a per-mile rate. The Allstate help center describes it as a “pay-as-you-go auto insurance product that uses a device to capture the miles you drive.” Drivers can choose a Pay-Per-Mile vehicle option, an Unlimited vehicle option (flat daily rate, no per-mile charge), or a combination across vehicles in the same household.

Mileage tracking runs through a plug-in device installed in the OBD-II port. The Allstate mobile app shows your usage and what you are spending. Allstate’s pay-per-mile car insurance resource confirms the program collects driving data including speed and braking trends in addition to mileage, which drivers should weigh on the privacy side.

Nationwide SmartMiles

Nationwide SmartMiles splits your premium into two parts. A fixed base premium covers the cost of having the car insured at all. A variable cost-per-mile charge runs on top, multiplied by the miles you drove in the prior billing cycle. Nationwide caps daily mileage charges at 250 miles, so a road trip does not blow up your bill.

Tracking happens via either a small plug-in device or, on eligible connected cars (2018 and newer Toyota connected vehicles, for example), through the vehicle itself, per Nationwide’s SmartMiles page. After the first renewal, drivers can earn up to a 10% Safe Driving Behavior Discount based on driving data captured during the first term.

Nationwide states SmartMiles is “not available in the following states: AK, HI, LA, NC, NY and OK.” That puts coverage at 44 states plus DC, per the SmartMiles FAQ. For how location shapes premiums more broadly, see our car insurance by state guide.

Other Pay-Per-Mile Players

A handful of smaller carriers operate in the pay-per-mile space. The NAIC’s telematics page calls out Metromile and Root Insurance as InsurTech startups that built UBI-only models. Small carriers like Mile Auto also use alternative mileage-verification methods in select states, which can appeal to drivers worried about telematics privacy. Mileage caps, base-rate ranges, and coverage availability vary state by state at every carrier, so always read the policy disclosure for your state before signing.

How the Math Works on Pay-Per-Mile

Pricing structures look similar across programs, but the levers move differently for each driver. Here is what carriers publicly disclose about how the bill gets built:

• Base rate. A flat daily or monthly charge that covers the vehicle whether you drive or not. The base reflects all the traditional rating factors that have always priced auto insurance, including liability limits, deductibles, age, ZIP code, and (in most states) credit-based insurance score. Allstate’s resource page and Nationwide’s SmartMiles page both describe this structure.
• Per-mile rate. A per-mile charge layered on top of the base. The rate varies by your risk profile, the coverage you select, and your state. Carriers do not publish a flat per-mile rate that applies everywhere because the rate is determined by their filed rating plan in each state.
• Daily caps. Nationwide caps SmartMiles charges at 250 miles per day, per the SmartMiles FAQ. That keeps a long road trip from spiking the bill.
• Behavior credit. Nationwide SmartMiles offers up to a 10% Safe Driving Behavior Discount after the first renewal. Milewise’s pricing already reflects driving data captured by the device.

Two drivers in the same state, on the same coverage, can land at very different total costs once the per-mile charges stack up over a month. The only way to know whether pay-per-mile beats your current bill is to pull a quote for your specific profile, in your state, with the same coverage limits as your current policy.

Where Pay-Per-Mile Tends to Save Money

Pay-per-mile is a math problem with one input that you control: the meter. If your annual mileage is well below the national average and your driving profile is steady, the meter works in your favor. The drivers who tend to win on pay-per-mile:

• Remote and hybrid workers. A two-day in-office cadence and a short commute on those days is the sweet spot.
• Retirees. Local errands, doctor visits, and the occasional grandchild pickup look great on a per-mile bill.
• Multi-car households with one rarely-used vehicle. The second car that sits 25 days a month is the prototypical Milewise or SmartMiles candidate.
• City drivers who default to transit. New York, Boston, DC, Chicago, and San Francisco households with one car they rarely touch.
• Students and infrequent drivers. A college student keeping a car at home that gets driven only at break is a strong fit.

Allstate’s resource page calls out the same drivers as well-suited for pay-per-mile, per the Allstate pay-per-mile car insurance article. Either way, it pays to compare car insurance quotes before you switch.

Where Pay-Per-Mile Costs More

The same meter that rewards low-mileage drivers punishes high-mileage drivers. The drivers who tend to lose on pay-per-mile:

• Long-commute drivers. A 60-mile round-trip commute five days a week is 15,000 miles a year before you account for weekends and errands. The per-mile charges add up faster than the savings on the base.
• Frequent road trippers. Daily caps help, but a string of long-drive weekends still bills hard.
• Rideshare and delivery drivers. Most pay-per-mile programs exclude or charge a commercial premium for rideshare or delivery work. Always check the carrier’s program rules for your state.
• Rural drivers with no transit option. When every trip to the grocery store is 18 miles each way, the meter never gets a break.

The decision is rarely about whether pay-per-mile is “good.” It is about whether your mileage profile fits the structure.

Privacy: What Carriers Are Tracking

Pay-per-mile programs collect more than just mileage. Allstate’s resource page is straightforward that programs can collect “trip distance, speed patterns and braking behavior,” per Allstate’s pay-per-mile article. The III notes that some states have enacted legislation requiring disclosure of tracking practices and that some insurers limit the data they collect, per the III’s telematics background page.

Three privacy points are worth nailing down before you enroll.

• What gets collected, whether mileage only or mileage plus speed, braking, time of day, and GPS location.
• How the collected information gets used, whether for premium calculation only or also marketing, claims, or third parties.
• How the information is protected and how long the carrier keeps it.

Allstate’s resource page recommends asking each of these questions of any pay-per-mile carrier before enrolling. That advice holds across the board.

How to Save on Insurance

Five concrete ways to use pay-per-mile to lower your auto insurance bill:

1. Pull your odometer photo first. Before quoting pay-per-mile, write down your odometer reading and the date. A year later, the difference is your real annual mileage. If it is under 8,000 miles, pay-per-mile is worth a serious quote.
2. Quote pay-per-mile alongside two traditional carriers. Quote Allstate Milewise or Nationwide SmartMiles, then quote two traditional carriers on the same coverage. Compare the total annual cost at your real mileage, not the carrier’s estimate.
3. Use the Unlimited option for one car if it makes sense. Allstate Milewise lets you mix a pay-per-mile vehicle with an Unlimited vehicle in the same household, per the Milewise help page. Use that flexibility when one car is driven daily and the other is barely touched.
4. Re-shop every 12 months. The NAIC reported that combined average premiums rose 14.41% in 2023. Loyalty discounts almost never beat a fresh quote.
5. Drop coverage you do not need. Rental reimbursement, high medical payments, and roadside assistance often duplicate coverage you already have through a credit card, a motor club, or your health plan. Pay-per-mile or not, that’s money on the table.

Pay-per-mile is not for everyone. For the right driver, though, it is one of the cleanest ways to make your auto insurance bill reflect what you actually do.
