Everything is in miles. Using kilometres? Enter km everywhere and read the results as km. The math is the same.
Two odometer readings
Type the numbers from your dash, like 24310. No commas. Old service invoices, oil-change stickers and inspection records usually show a reading and a date. Readings a few months or more apart give the steadiest estimate.
A typical week
Include commuting, errands and weekend driving. For a week with a road trip, use your usual week instead.
Lease check (optional)
Leave blank if you don't lease. If your lease lists a total (like 36,000 over 3 years), divide by the years.
6,300 miles in 175 days: about 13,140 miles a year.
The yearly figure is miles per day × 365 from your readings, or miles per week × 52. Monthly, weekly and daily averages split it by 12, 52 and 365, so a week comes out a little more than 7 days' worth.

Road44, the driving log app mentioned below, is our app. National mileage figures come from the Federal Highway Administration and were checked in September 2026. This calculator projects miles only. It doesn't estimate taxes, reimbursement or lease charges.
How to calculate your annual mileage
You can do it two ways, and the calculator handles both. If you have odometer readings, use them. They give the better answer.
Method 1: two dated odometer readings. Subtract the older reading from the newer one, divide by the days between them, then multiply by 365. Say your odometer showed 24,310 on January 5 and 30,610 on June 29. That's 6,300 miles over 175 days, exactly 25 weeks. 6,300 ÷ 175 is 36 miles a day, and 36 × 365 is 13,140 miles a year.
Method 2: a typical week × 52. If you drive about 250 miles in a normal week, 250 × 52 gives 13,000 miles a year. It's quick, but it only knows about normal weeks. Holidays, road trips and a week off sick all drop out, so it tends to be the rougher estimate.
Either way, the calculator works out the yearly figure first and then splits it: ÷ 12 for a month, ÷ 52 for a week and ÷ 365 for a day. Since 52 weeks is only 364 days, a week comes out a little more than 7 days' worth. In the example, 36.0 miles a day shows as 253 a week, not 252. The upside is that the weekly and monthly figures multiply back to the yearly one.
Dates are counted exactly, leap days included, and a daylight-saving change never shaves an hour off the count. Readings exactly 365 days apart need no projection, because the miles between them are your yearly mileage. A full year that includes February 29 is 366 days, so the calculator scales it back to 365: 12,000 miles from January 1, 2024 to January 1, 2025 works out to 11,967 a year.
How your mileage compares
The Federal Highway Administration's Our Nation's Highways 2026 puts the average at 13,735 miles per licensed driver in 2024. That was the fourth year of increases in a row after a low of 12,724 in 2020. The high point in its table is 15,005 miles, in 2005.
Counted per vehicle, the number is lower. FHWA's Highway Statistics table VM-1 shows 10,787 miles per light-duty vehicle in 2024. The first figure divides total miles by the number of licensed drivers, and the second divides them by the number of vehicles.
The average isn't a target. A long commute, gig or delivery work, or a rural home far from stores and schools can put you well above it, and working from home can put you well below. For insurance, a lease or a car budget, go by your own number.
Why your yearly mileage matters
- Insurance. Insurers ask for an annual mileage estimate and set their own bands. Give them an honest figure, and if your driving changes a lot during the policy, tell them.
- Leases. Allowances are stated per year. The Federal Reserve's consumer leasing guide says they're "often 12,000 or 15,000 miles per year," and your own limit is in the lease agreement. Put it in the lease check a few months in to see if you're on pace. The same guide notes that negotiating a higher limit up front often costs less than paying for extra miles at the end.
- Maintenance and resale. Most service schedules are set in miles, so your yearly figure helps you plan the next oil change or tire rotation. The Fed's guide also points out that more miles lower a car's trade-in or resale value.
- Work driving. If you drive for work, a log of business miles backs up a business-mileage deduction or a reimbursement claim. IRS Publication 463 asks for the mileage for each business use and the total miles for the year. A projection doesn't replace that log. This is general information, not tax advice.
Track your actual miles in Road44
A projection is only as good as the readings behind it. Logging each drive gives you real numbers to work from, and a record if you need one. Our driving log template vs app guide covers where paper and phone logs each go wrong. Road44 is the log we built:
- Choose Distance as your goal and the home screen shows your miles for All-time, This month or This week, with a bar chart by day for the week and month views and by month for all-time.
- Each drive can store a start and end odometer reading or a distance you type in. Every field is optional, and a typed distance takes priority over the odometer pair.
- Start a drive live with one tap, or add past drives afterward. The calendar shows each day's distance.
- Tag drives as Business, Personal, Commute or Medical for free, and use miles or km.
- An all-time distance goal is free. Weekly and monthly recurring goals are part of Pro, as is the Insights screen with average trip distance, a trend chart and breakdowns by purpose and vehicle.
- The logbook exports free as Text, CSV, PDF or PNG, with no watermark. Export all your drives as CSV and you can total any year in a spreadsheet.
There's no account, and your drives stay on your phone. Road44 is a personal record, not an official or certified logbook, and not tax advice. You can see how Road44 compares with other driving log apps or browse our other driving tools.
Frequently Asked Questions
Common questions about annual mileage calculator
How do I work out my annual mileage?
There are two ways. With two odometer readings and their dates, divide the miles between them by the days between them and multiply by 365: 6,300 miles over 175 days is 36 miles a day, or 13,140 a year. Without old readings, multiply a typical week by 52: 250 miles a week is 13,000 a year. Readings are better when you have them, because they include the weeks that weren't typical.
How many miles does the average American drive in a year?
The Federal Highway Administration puts it at 13,735 miles per licensed driver in 2024, the fourth straight yearly rise since the 2020 low of 12,724. The peak was 15,005 in 2005 (Our Nation's Highways 2026, Table 5-6). That figure is total vehicle miles divided by the number of licensed drivers. Counted per vehicle instead, FHWA's Highway Statistics table VM-1 gives 10,787 miles per light-duty vehicle in 2024.
Where can I find an old odometer reading?
Anything that recorded the mileage with a date works: service or repair invoices, oil-change window stickers, tire receipts, inspection or emissions reports, and the odometer statement from when you bought the car. Pair the oldest one you trust with today's reading. A span of a few months or more gives the steadiest estimate.
What annual mileage should I give my car insurer?
Give the honest estimate from the calculator, not a hopeful one. Insurers set their own mileage bands, and some offer lower rates to people who drive less, so ask yours how they define low mileage and whether they check the odometer. Leave room for road trips and job changes. If your driving changes a lot during the policy, tell your insurer.
Will I go over my lease mileage?
Enter your yearly allowance in the lease check. The calculator compares it with your projected miles per year and shows how far over or under you are. The Federal Reserve's consumer leasing guide says most leases limit miles, "often 12,000 or 15,000 miles per year," and your allowance is stated in the lease agreement. The same guide says negotiating a higher limit up front often costs less than paying for extra miles at the end.
Why isn't the weekly average exactly 7 times the daily average?
A year is 52 weeks plus one day (two extra days in a leap year). The calculator projects the year first, then splits it into 12 months, 52 weeks and 365 days, so a week comes out slightly more than 7 days' worth. For example, 36.0 miles a day becomes 253 a week, not 252. That keeps weekly × 52 and monthly × 12 equal to the yearly figure.
How accurate is a projection from a few weeks of readings?
That depends on how typical those weeks were. A short span stretches a handful of drives across a whole year, so a single road trip or a week off skews it. The calculator adds a note when your readings are under 30 days apart. Readings exactly 365 days apart give your actual yearly mileage rather than a projection. A full-year span that includes February 29 is 366 days, so the calculator scales it to 365.
Do I need a mileage log for taxes?
If you use your car for business, IRS Publication 463 asks for records of "the mileage for each business use, and the total miles for the year." Records should be made "at or near the time" of the use, and a log kept weekly that accounts for use during the week "is considered a timely kept record." A projection like this one is a planning estimate, not a record. Keep a log as you drive and total it at year end. This is general information, not tax advice.
