> The miles per year calculator converts the distance you drive in a day, week, month or other period into miles per day, week, month and year, and estimates the yearly fuel use and cost.

## Inputs

- I know the distance I drive per
- Distance in that period (mi, km, m, nmi)
- Fuel economy given as
- Fuel economy (mpg (US), mpg (UK), km/L)
- Fuel consumption (L/100 km)
- Fuel price (/US gal, /L, /UK gal)

## Results

- Distance per year
- Per month
- Per week
- Per day
- Fuel per year
- Fuel cost per year

## 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 economy
```

## Explanation

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.

### 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

## Worked 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.

## FAQ

**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 do lease mileage limits work?**
Leases allow a set yearly mileage (often 10,000–15,000) and charge per mile over, typically 15–30 cents.

**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).
