TOOLDon't get burned by lease kilometre limits
Every lease comes with a kilometre allowance the dealer sets — commonly 16,000, 20,000, or 24,000 km a year. Drive more and you pay a per-kilometre overage fee at the end, which adds up fast. This tool turns your allowance into a simple daily and monthly budget, then tells you whether your real driving will blow past it and what that would cost.
How it works
Total allowed = annual allowance × (term ÷ 12)
Overage cost = (your projected total − total allowed) × $/km
If your projected driving is under the allowance, your overage cost is zero and the tool shows how much room you have left. If you're over, it shows the kilometres and the dollar charge.
What to do if you'll go over
- Buy kilometres up front. Dealers sell extra km at signing for less than the end-of-lease overage rate — pre-purchasing is usually cheaper.
- Pick a higher allowance. A slightly higher monthly payment can beat a big overage bill if you're a high-mileage driver.
- Consider buying instead. If you drive a lot, a purchase has no mileage penalty — compare with the car loan calculator and the car lease calculator.
Estimates are for planning only. Overage rates, allowances and rounding rules vary by contract, and some leases measure in miles rather than kilometres. Confirm the exact terms with your dealer.
Frequently asked questions
How much can I drive per month on a lease?
Divide your annual kilometre allowance by 12. A common 20,000 km/year lease allows about 1,667 km per month or roughly 55 km per day. This calculator shows your exact per-month and per-day budget for any allowance.
How is lease mileage overage calculated?
Multiply the kilometres you go over your total allowance by the per-kilometre overage rate in your contract, often 10 to 25 cents per km. For example, 5,000 km over at $0.15/km is a $750 charge at lease end.
Is it cheaper to buy extra kilometres up front?
Usually yes. Dealers sell additional kilometres at a lower rate when you buy them at signing than the overage rate charged at the end of the lease. If you expect to go over, pre-purchasing is often the cheaper option.
