About Lease Mileage Cost Calculator
Leases cap the miles you can drive, and going over costs a set amount per mile. Enter the miles you have actually driven, the allowance in your contract, and the overage fee. The tool finds the excess miles — or zero if you are under — and multiplies by the fee.
It is free, needs no sign-up, and runs entirely in the browser.
Formula & Mathematical Calculation
Excess Miles = f(Actual Miles Driven, Mileage Allowance, Overage Fee ($/mile))
Calculated according to standard finance formulas implemented in the calculator core.
Calculation Example
Suppose you drove 45,000 miles against a 36,000-mile allowance with an overage fee of $0.25/mile.
Excess Miles = 45,000 − 36,000 = 9,000 miles. Overage Charge = 9,000 × 0.25 = $2250.
Key Benefits
- Shows both the excess mileage and the resulting charge in one step
- Never returns a negative overage: driving under the allowance yields zero excess miles
- Lets you test different end-of-lease mileage figures before you turn the car in
- Free and runs in your browser with no account
