Pay-per-mile car insurance charges a fixed base rate of $30 to $60 per month plus $0.02 to $0.10 for every mile you drive. Nationwide SmartMiles, available in 40 states, leads the market with a 250-mile daily cap and safe driving discounts up to 10%. Drivers logging fewer than 7,500 miles annually can save 20% to 40% compared to traditional policies, translating to $500 to $1,500 per year in reduced premiums.
What Is Pay-Per-Mile Car Insurance?
Pay-per-mile car insurance splits your premium into two components: a fixed monthly base rate between $30 and $60, plus a variable per-mile charge of $0.02 to $0.10. Nationwide, Allstate, Metromile, and Liberty Mutual all offer versions of this coverage type, though each company structures pricing differently. The average American drives 13,473 miles per year according to the Federal Highway Administration, but roughly 35% of U.S. households include at least one vehicle driven under 7,500 miles annually.
Traditional auto insurance charges the same flat premium regardless of whether you drive 3,000 or 15,000 miles. Pay-per-mile policies eliminate that mismatch by tying your cost directly to actual usage. A remote worker driving 4,000 miles a year could pay $58 per month with Nationwide SmartMiles, compared to $155 or more for a standard full-coverage policy in the same ZIP code.
Insurers use several overlapping terms. "Pay-per-mile" specifically means a base rate plus a per-mile charge. "Pay-as-you-go" (like Hugo) charges by the day or week and tracks driving behavior, not just mileage. "Pay-as-you-drive" (PAYD) is the broadest umbrella category. Check our PAYD, PHYD, and MHYD explainer for a complete breakdown of each model.
How Pay-Per-Mile Insurance Works
How Your Mileage Gets Tracked
Nationwide and Allstate mail a small OBD-II plug-in device that connects to the diagnostic port found in every car built after 1996. Metromile uses a similar Pulse device that transmits GPS data to calculate mileage in real time. Mile Auto takes a different approach entirely: drivers submit periodic odometer photos through text or email, requiring no hardware installation at all.
Each tracking method feeds mileage data to the insurer throughout the billing cycle. Nationwide's SmartMiles app displays daily mileage, projected monthly cost, and trip history. Allstate Milewise shows a running daily charge that updates after every trip. Metromile's app includes a street-sweeping alert feature and a car-health diagnostic tool alongside its telematics tracking dashboard.
Billing Structure and Daily Mileage Caps
Nationwide caps billable mileage at 250 miles per day, so a 600-mile road trip costs the same as driving 250 miles. Allstate Milewise uses daily billing instead of monthly cycles, charging roughly $0.50 to $1.00 per day plus the per-mile fee. Liberty Mutual ByMile calculates your bill at the end of each monthly billing period based on total tracked mileage.
A driver with a $45 base rate and $0.06 per-mile charge who drives 500 miles in a month pays $75 total ($45 + $30). That same driver logging 1,200 miles would pay $117 ($45 + $72). Compare those figures to the national average full-coverage premium of $2,458 per year, or roughly $205 per month, according to Bankrate's 2026 data.

Nationwide SmartMiles
Nationwide SmartMiles covers 40 states, making it the most widely available pay-per-mile program in the U.S. The per-mile charge ranges from $0.05 to $0.12 depending on your risk profile and ZIP code. Safe driving behavior earns an additional discount of up to 10%, which stacks on top of the low-mileage savings.
The 250-mile daily cap is the standout feature. A 500-mile drive from Dallas to New Orleans counts as only 250 billable miles at $0.08 per mile, saving you $20 on that single trip. Nationwide also offers full access to its standard coverage options including comprehensive and collision, roadside assistance, and rental reimbursement.
Allstate Milewise
Allstate Milewise uses a daily base charge of $0.50 to $1.00 instead of a monthly rate. That structure means you pay less during weeks when the car sits in the garage. The program operates in 17 states plus Washington, D.C., including Arizona, Delaware, Florida, Illinois, Indiana, Massachusetts, Maryland, New Jersey, Ohio, Oregon, Pennsylvania, Texas, Virginia, Washington, and West Virginia.
Milewise does not offer bundled safe-driving discounts like Nationwide does. Your savings depend entirely on keeping mileage low. At $0.75 per day and $0.06 per mile, a driver covering 400 miles in a 30-day month pays about $46.50 total ($22.50 base + $24 mileage).
Metromile (via Lemonade)
Metromile pioneered pay-per-mile insurance and now operates under Lemonade's umbrella in 8 states: Arizona, California, Illinois, New Jersey, Oregon, Pennsylvania, Virginia, and Washington. Monthly base rates start at $29, with per-mile fees averaging $0.08 to $0.14. California drivers get a unique setup because state law (Proposition 103) requires odometer-based rating rather than GPS tracking.
The Pulse device plugs into your OBD-II port and provides car-health diagnostics alongside mileage tracking. Metromile reports that its average customer saves more than 40% compared to traditional insurance, though that figure reflects self-selected low-mileage drivers.
Liberty Mutual ByMile
Liberty Mutual's ByMile program charges a monthly base rate of $35 to $60 plus $0.04 to $0.10 per mile across 16 states. The program provides the same coverage options available on standard Liberty Mutual policies, including accident forgiveness and new car replacement. Enrollment requires downloading the Liberty Mutual app and plugging in the provided OBD-II device.
The Break-Even Mileage: When Pay-Per-Mile Stops Saving You Money
Every pay-per-mile policy reaches a point where the per-mile charges push your total above what a traditional policy would cost. That break-even point depends on your base rate, per-mile fee, and the traditional premium available in your area.
| Annual Miles | Nationwide SmartMiles* | Allstate Milewise* | Metromile* | Traditional Policy* |
|---|---|---|---|---|
| 3,000 | $780 | $453 | $588 | $2,458 |
| 5,000 | $940 | $573 | $748 | $2,458 |
| 7,500 | $1,140 | $723 | $948 | $2,458 |
| 10,000 | $1,340 | $873 | $1,148 | $2,458 |
| 12,000 | $1,500 | $993 | $1,308 | $2,458 |
| 15,000 | $1,740 | $1,173 | $1,548 | $2,458 |
*Estimated annual costs assume: Nationwide ($45/mo base + $0.08/mi), Allstate ($0.75/day + $0.06/mi), Metromile ($35/mo base + $0.08/mi). Traditional policy figure is the national average full-coverage premium per Bankrate 2026 data. Your actual rates will vary by state, driving record, and vehicle.
Calculate your own break-even mileage: (Traditional Annual Premium - Annual Base Rate) / Per-Mile Rate = Break-Even Miles. For a driver paying $2,458 per year traditionally with a $45/month base and $0.08/mile pay-per-mile rate: ($2,458 - $540) / $0.08 = 23,975 miles. That means pay-per-mile stays cheaper until you exceed 23,975 annual miles. Most drivers hit the crossover point between 10,000 and 15,000 miles, depending on their traditional premium and per-mile rate.
How Much Can You Actually Save?
Nationwide reports that SmartMiles customers save an average of 25% compared to its standard auto policy. Metromile claims average savings exceeding 40%, though that figure reflects a self-selected pool of low-mileage drivers. MoneyGeek's 2026 analysis found that drivers under 5,000 annual miles save $1,000 to $2,000 per year depending on their state and coverage level.
A retiree in Phoenix driving 3,000 miles annually could pay roughly $780 with Nationwide SmartMiles instead of $2,458 for the national average full-coverage policy. That gap of $1,678 per year adds up to $8,390 over five years. Remote workers averaging 4,200 miles per year save between $900 and $1,400 annually across the four major providers.
Savings disappear at higher mileage levels. At 15,000 miles per year, Nationwide SmartMiles costs approximately $1,740, which still beats the $2,458 national average. The real advantage evaporates for drivers consistently above 12,000 to 15,000 miles, because a traditional policy with bundled discounts can match or beat pay-per-mile pricing at those distances.
Who Should Get Pay-Per-Mile Insurance?
Remote Workers and Hybrid Employees
The U.S. Census Bureau reported that 27.6% of workers operated remotely at least part-time in 2025. A fully remote worker driving only for errands and weekend outings might log 3,000 to 5,000 miles per year. At that usage level, Nationwide SmartMiles could cost $780 to $940 annually, saving $1,518 to $1,678 versus the national average policy.
Retirees and Seniors
AAA reports that drivers over 65 average 7,646 miles per year, nearly 6,000 miles less than the overall U.S. average of 13,473. Combining pay-per-mile coverage with a senior low-mileage discount from Nationwide can reduce annual premiums by 30% or more. Retirees in Florida, where full-coverage premiums average $3,244 per year according to The Zebra, stand to save even more.
Multi-Car Households
Families with two or three vehicles often have one car that sits in the driveway most of the week. Switching that second or third vehicle to a pay-per-mile plan while keeping the daily driver on traditional coverage is a common strategy. A household saving $100 per month on the seldom-used vehicle keeps full protection during the occasional weekend trip, since the 250-mile daily cap at Nationwide prevents cost spikes.
Snowbirds and Seasonal Drivers
Snowbirds who garage a vehicle for 4 to 6 months per year pay traditional premiums even during months of zero driving. Pay-per-mile coverage charges only the base rate during those idle months. A snowbird paying $45 per month in base rate for 5 dormant months spends $225 total for that period, compared to roughly $1,024 at the average monthly full-coverage premium of $205.
Who Should Skip Pay-Per-Mile Insurance?
- Commuters driving 40+ miles round-trip daily rack up 10,400+ miles per year from work travel alone, pushing past the break-even threshold at most carriers.
- Rideshare and delivery drivers need commercial or gig-specific coverage because Nationwide, Allstate, and Metromile all exclude commercial vehicle use from pay-per-mile programs.
- Road-trip enthusiasts logging 2,000+ miles in a single month would pay $160+ in per-mile fees on top of their base rate, negating most savings.
- Drivers in states without pay-per-mile options (Alaska, Hawaii, Louisiana, New York, North Carolina, and Oklahoma) cannot access these programs due to state-specific insurance regulations.
Privacy and Data Concerns
Every pay-per-mile insurer collects location data, mileage totals, and trip timestamps through its tracking device or app. Nationwide's SmartMiles device records GPS coordinates, driving speed, and braking patterns. Allstate Milewise tracks similar data points to calculate daily charges. Metromile's Pulse device collects real-time driving data including engine diagnostics.
California's Proposition 103 restricts how insurers can use telematics data for rating purposes, which is why Metromile requires odometer photos instead of GPS tracking in that state. States like Illinois and Virginia have enacted consumer data protection laws that limit how long insurers can retain driving data. Check our detailed guide on data privacy and pay-as-you-go insurance for state-by-state tracking regulations.
Mile Auto offers the most privacy-friendly approach: odometer photo submissions instead of continuous GPS tracking. You sacrifice the convenience of automatic mileage logging, but Mile Auto never collects your trip routes, driving speed, or location data. The trade-off costs nothing extra in terms of premium.
How to Sign Up for Pay-Per-Mile Insurance
- Check your annual mileage. Review your car's odometer or check your insurer's app to confirm you drive under 10,000 miles per year. The U.S. Department of Energy's fuel economy calculator at fueleconomy.gov can estimate your annual driving based on commute distance.
- Compare quotes from at least 3 providers. Enter your ZIP code at Nationwide, Allstate, and Metromile (or Liberty Mutual) to see base rates and per-mile fees specific to your profile. Rates vary by as much as 50% between carriers for the same driver.
- Verify state availability. Nationwide covers 40 states, but Metromile operates in only 8. Confirm your state qualifies before spending time on applications.
- Choose your tracking method. If GPS tracking concerns you, ask about odometer-reading options. Mile Auto and some Metromile plans in California accept photo submissions.
- Review your coverage limits. Pay-per-mile policies offer the same coverage types as traditional insurance, including liability, comprehensive, collision, and uninsured motorist protection. Match or exceed your current limits.
- Install the device and download the app. Most carriers ship an OBD-II device within 3 to 5 business days. Your switch to pay-per-mile takes effect once the device starts tracking.
Frequently Asked Questions
Does pay-per-mile insurance cover the same things as regular car insurance?
Nationwide SmartMiles, Allstate Milewise, and Liberty Mutual ByMile offer identical coverage options to their standard policies: liability, comprehensive, collision, uninsured/underinsured motorist, medical payments, and roadside assistance. Metromile also provides full-coverage options. Smaller providers like Mile Auto may limit optional coverages. Compare the specific coverage menu at each carrier before enrolling.
What happens if I take a long road trip?
Nationwide caps billable mileage at 250 miles per day. A 1,000-mile, two-day drive from Chicago to Miami costs the per-mile fee on only 500 miles instead of 1,000. Metromile caps daily mileage at 150 miles. Allstate Milewise does not publicize a specific daily cap, so check your policy terms before planning extended travel.
Can I switch back to traditional insurance anytime?
All four major pay-per-mile providers allow cancellation at any time without penalty. Nationwide, Allstate, and Liberty Mutual will transition you to their standard auto policy within the same billing cycle. Metromile requires you to obtain a new policy with a different carrier since it offers only pay-per-mile coverage. Compare your options through a tool like telematics savings calculators before making the switch.
Is pay-per-mile insurance available for leased or financed vehicles?
Leased and financed vehicles qualify for pay-per-mile coverage at all four major providers. Your lender or leasing company will still require full coverage (comprehensive + collision), which pay-per-mile policies include as an option. Verify that your chosen plan meets the specific coverage minimums your lender requires, typically 100/300/100 liability with $500 deductibles.
