Annual mileage matters for insurance quotes, lease contracts (often 10,000–15,000 miles a year), car valuations and budgeting. The average American drives about 13,500 miles a year; in the UK the average is about 7,000 miles.
How to use the Miles per Year Calculator
- I know the distance I drive per
- Distance in that period
- Fuel economy given as
- Fuel economy
- Fuel consumption
- Fuel price
Results update as you type, and every field accepts the units shown in its menu.
How it works
Choose the period you know, enter the distance for it, your fuel economy and fuel price.
Tips
- Use your own measured figures – fuel economy, speed and prices vary a lot with driving style, traffic, load and season.
- Pick the unit in each field’s menu (miles or kilometres, mpg or L/100 km); the calculator converts everything for you.
- Fill up to the brim twice and divide the distance by the fuel added to measure real fuel economy.
- For vehicle modifications, treat results as a starting point and confirm with the parts maker or a professional mechanic.
Common mistakes to avoid
- Mixing US and imperial (UK) gallons – a UK gallon is about 20% bigger.
- Using the advertised fuel economy instead of real-world figures.
- Forgetting tolls, parking and wear and tear when comparing driving with public transport.
Inputs explained
| Field | What to enter |
|---|---|
| I know the distance I drive per | Choose one: Day, Week, Month, Quarter … |
| Distance in that period | Units: mi, km, m, nmi |
| Fuel economy given as | Choose one: Distance per volume (mpg, km/L), Litres per 100 km |
| Fuel economy | Units: mpg (US), mpg (UK), km/L |
| Fuel consumption | In L/100 km |
| Fuel price | Units: /US gal, /L, /UK gal |
What each result means
- Distance per year = [Distance in that period]×[I know the distance I drive per]
- Per month = [Distance per year]÷12
- Per week = [Distance per year]÷52.1786
- Per day = [Distance per year]÷365.25
- Fuel cost per year = [Fuel per year]×[Fuel price]
Example values
How the main result changes when Distance in that period changes and everything else stays at the example values above:
| Distance in that period (mi) | Distance per year (mi) |
|---|---|
| 125 | 6,522 |
| 187.5 | 9,783 |
| 250 | 13,045 |
| 312.5 | 16,306 |
| 375 | 19,567 |
| 500 | 26,089 |
Formula
Miles per year = distance per period × periods per year (day 365.25, week 52.18, month 12, quarter 4, half-year 2)Fuel per year = miles per year ÷ fuel economyWorked example
Inputs — I know the distance I drive per: Week; Distance in that period: 250 mi; Fuel economy given as: Distance per volume (mpg, km/L); Fuel economy: 25 mpg (US); Fuel consumption: 8 L/100 km; Fuel price: $3.5 /US gal.
Results — Distance per year = 13,045 mi; Per month = 1,087 mi; Per week = 250 mi; Per day = 35.7 mi; Fuel per year = 522 US gal; Fuel cost per year = $1,826.25.
Frequently asked questions
How many miles a year is average?
About 13,500 miles in the U.S. (FHWA data), about 7,000 in the UK and 8,500 in Australia.

How many miles a year is too many for a used car?
Above about 15,000 miles a year is usually considered high mileage.
What formula does the Miles per Year Calculator use?
Miles per year = distance per period × periods per year (day 365.25, week 52.18, month 12, quarter 4, half-year 2).
