Estimate how far you will drive by the end of your lease and what excess mileage could cost. Enter your contract dates, odometer readings, allowance, and charge per mile or kilometer. The calculator also shows how much distance you have left per day.
Enter the full allowance from your contract. The starting values are an example.
For 12,000 miles/year over 3 years, enter 36,000 miles.
Enter the charge from your contract. For example, enter $0.25 as 0.25.
Unit changes convert your distances and per-distance charge together. Currency changes relabel amounts without converting them.
If your average driving pace continues until the lease ends.
30,510.8 mi projected at lease end · 0 mi above your allowance.
By this reading date, you have driven 3,238.4 mi less than the allowance spread evenly over the lease.
How much you can average from this reading onward.

The seven-day budget stops at the end of the lease. This estimate uses the mileage charge you entered. It excludes taxes, contract adjustments, wear charges, and other fees.
Distance driven during the lease
Current odometer − starting odometer
Projected distance at lease end
Distance driven ÷ elapsed calendar days × total lease days
Estimated excess mileage charge
Max(0, projected distance − total allowance) × contract charge
Remaining daily budget
Max(0, total allowance − distance driven) ÷ remaining days
This example covers January 1, 2025 to January 1, 2028, with a 36,000-mile allowance and a $0.25 charge per excess mile. The odometer starts at 800 miles and reads 16,800 miles on January 1, 2026.
| Item | Result | Detail |
|---|---|---|
| Driven during the lease | 16,000 mi | 365 elapsed days |
| Projected at lease end | 48,000 mi | 12,000 excess mi |
| Projected excess charge | $3,000.00 | At the entered $0.25 per mile |
Subtract the starting odometer reading from the reading at the end of the lease. Subtract the total contract allowance from that distance, use zero if the result is negative, then multiply any excess distance by the charge in your agreement.
Enter the total allowance for the full lease. An allowance of 12,000 miles per year for three full years gives 36,000 miles. For a partial year or adjusted agreement, use the total permitted distance confirmed in your contract.
A vehicle can already have miles on its odometer when you receive it. Those miles should not be counted as distance you drove during the lease. Enter both readings so the calculator uses their difference.
No. It estimates excess mileage at your entered contract price if your driving pace continues. Other fees, taxes, waivers, allowance changes, or contract terms may affect the amount your lessor charges.
Yes. Choose kilometers to convert the odometer readings, allowance, and per-distance charge together. Choose GBP, CAD, AUD, or USD for the amounts you enter. Currency selection does not convert money between currencies.
On the start date, enter the starting reading to see the remaining distance budget. A projection needs a later reading. On the end date, enter the final reading to calculate the excess charge directly. Reading dates must fall within the lease period.
