How Cost per Mile Calculator Works
This tool works by dividing fuel cost by miles driven, or by dividing the fuel price by the vehicle’s miles per gallon (MPG).
- Step 1

Use recorded spending and miles, or use the price per gallon and MPG.
- Step 2
Enter spending and miles
Type total fuel spending and miles driven for the same period.
- Step 3
Or enter price and MPG
Type the price per gallon and the vehicle MPG.
- Step 4
Read the cost per mile
The calculator shows cost per mile, cost per 100 miles, and cost per 1,000 miles.
Cost per Mile Calculator Formula
The formula divides fuel cost by miles driven.
Cost per Mile = Total Fuel Cost ÷ Miles Driven
Cost per Mile = Price per Gallon ÷ MPG
- Total Fuel Cost
- = fuel spending in the period
- Miles Driven
- = odometer miles in the same period
Worked Example
- A driver spent $186.40 on fuel and drove 1,450 miles (2,334 km) in one month.
- Cost per mile = $186.40 ÷ 1,450 = $0.129 per mile (12.9 cents).
- Cost per 100 miles = $12.86.
- Check with price and MPG: $3.45 ÷ 26.8 MPG = $0.129 per mile.

What is a Cost per Mile Calculator?
A Cost Per Mile Calculator is a unit cost tool that divides fuel cost by miles driven to show what each mile costs in fuel.
Cost per mile is the standard unit for comparing vehicles, pricing trips, and checking reimbursement rates. A per-mile figure works for a 3-mile errand and a 3,000-mile road trip alike. The Cost Per Mile Calculator gives that figure from either receipts or price and MPG.
Fuel is one part of total cost per mile. Depreciation, insurance, tires, and maintenance add more on top of the fuel figure.
