How lease mileage allowance works
Annual allowance
Most lease agreements set a yearly distance allowance, such as 8,000, 10,000 or 12,000 miles per year. This calculator converts that into a total contract allowance using your lease term.
Your mileage position
Your allowance to date shows how much of your total mileage allowance you could have used by this point in the lease. Comparing it with the distance you have actually driven shows whether you are currently over or under that figure.
Projected mileage
Projected mileage estimates your end-of-lease mileage if you continue at your current usage level. This makes it easier to adjust early rather than wait for excess mileage charges at the end.

Lease mileage calculator FAQ
What is annual mileage allowance?
Annual mileage allowance is the distance you are allowed to drive each year under your lease agreement. The total contract allowance depends on both the yearly allowance and the lease term.
How do you calculate total contract allowance?
Total contract allowance is calculated by multiplying the annual mileage allowance by the lease term in years. For example, 10,000 miles per year over 36 months equals 30,000 miles in total.
What does projected over/under allowance mean?
Projected over/under allowance is the gap between your projected lease-end mileage and your total contract allowance. It shows how far over or under the allowance you are projected to finish.
Can I change the distance unit?
Yes. Use the unit toggle at the top of the calculator. The labels and calculations update instantly.
Does this save my lease data?
No. The calculator runs entirely in your browser. Share links work by storing values in the page URL only.
How this calculator works
We project your end-of-lease mileage by combining your current mileage, allowance, and time remaining. This helps you see if you are on track or likely to exceed your contract.
Example
If your lease allows 12,000 miles per year over 36 months (36,000 total) and you are currently trending toward 42,000 miles, you could exceed your allowance by 6,000 miles.
