PCP Excess Mileage Calculator

Estimate the contractual excess-mileage charge from your PCP allowance, expected mileage and agreement terms.

Use this calculator

Enter the contracted allowance, expected mileage, term and contract excess-mileage charge.

What your result means

The estimate compares your expected mileage with the contracted annual allowance over the agreement term, then applies the pence-per-mile charge you enter to any excess miles.

If expected mileage is at or below the allowance, excess mileage and the estimated charge are both £0. Your actual PCP contract governs any charge.

Canonical worked example

Illustrative contract terms: 8,000 miles/year allowance, 10,000 miles/year expected, 4 years and 10p per excess mile.

Contracted total miles
32,000 miles
Expected total miles
40,000 miles
Excess miles
8,000 miles
Estimated excess-mileage charge
£800.00

32,000 contracted miles versus 40,000 expected miles gives 8,000 excess miles and an £800 illustrative charge.

How PCP mileage allowance works

Contracted mileage is normally agreed at the start of a PCP agreement. If the vehicle is returned and the contract terms apply, exceeding that allowance can create a contractual excess-mileage charge.

The rate varies by agreement. This calculator uses only the charge you enter and does not present it as a typical or current rate.

What is outside this estimate

Vehicle-condition charges are separate from mileage and are not modelled. Voluntary termination, early-return rules, changes to an agreement and any other contract-specific arrangements are also outside this calculation.

Check the agreement and lender documentation for the terms that apply to your vehicle and end-of-agreement choice.

Practical guidance

Use a realistic annual-mileage estimate, including commuting, regular trips and irregular driving. Compare the result with your contract before mileage accumulates rather than waiting until the agreement ends.

If your travel pattern has changed, ask the provider what options are available under your agreement. This page estimates the entered contract terms; it does not recommend a particular contract action.

Assumptions and limitations

  • The annual allowance, expected annual mileage and pence-per-mile charge are unchanged across the term.
  • The estimate uses only mileage and the entered excess rate.
  • Actual PCP contract terms, vehicle condition, voluntary termination and early-return rules are not modelled.

Helpful questions

What if I stay within my annual mileage allowance?

The excess mileage is zero in this model, so the estimated excess-mileage charge is £0.

Is 10p per mile a typical PCP charge?

No. It is an illustrative editable input. Actual charges vary by agreement.

Does this include vehicle-condition charges?

No. Condition charges are separate from excess mileage and depend on contract terms.

How can I estimate my annual mileage?

Use the Annual Car Mileage Calculator to build an estimate from commuting and other driving.

Does this change my PCP monthly payment?

No. This estimates a possible end-of-agreement mileage charge only. The PCP Car Finance Calculator models standard PCP payment assumptions.
