Calculate an entered excess-distance charge from a lease allowance, actual distance, and per-unit contract charge.
The calculator keeps the balance, rate convention, payment timing, fees, and term visible so you can reproduce the result and compare it with an actual offer or statement.
The cash-flow relationship
Place every amount at the correct time
Excess distance = max(actual distance − allowance, 0); entered excess-distance charge = excess distance × charge per unit.

Read the result in context
Use the estimate with its contract assumptions
An allowance of 30,000 km, actual distance of 32,500 km, and charge of 0.20 per km produces a 500 excess-distance charge.
Use the exact unit and charge disclosed by the lease. This tool excludes wear, disposition, tax, early-termination, and other contractual charges.
Quick guide
How to use this calculator
Enter the contract or offer figures using one consistent currency and distance unit.
Keep rates, terms, fees, rebates, and timing aligned with the visible labels.
Compare the outputs with the stated exclusions before making a decision.
Calculation method
Calculation method
Excess distance = max(actual distance − allowance, 0); entered excess-distance charge = excess distance × charge per unit.
Entered monetary components use exact fixed-decimal arithmetic. Amortizing comparisons reuse the reviewed stable loan schedule and round only for presentation.

An allowance of 30,000 km, actual distance of 32,500 km, and charge of 0.20 per km produces a 500 excess-distance charge.
Excess distance = max(actual distance − allowance, 0); entered excess-distance charge = excess distance × charge per unit.

Descriptive comparison
These tools describe entered cash flows and contract terms. They do not recommend a lender, lease, refinance, incentive, or purchase.
International scope
No currency, country, tax, lender rule, distance system, credit eligibility standard, or consumer-protection outcome is assumed.
Calculator-specific assumptions
Use the exact unit and charge disclosed by the lease. This tool excludes wear, disposition, tax, early-termination, and other contractual charges.
