PCP Excess Mileage: Estimate Your Exposure

PCP agreements commonly set an annual or total mileage allowance and an excess-mileage rate. A projection can show whether you are trending over the allowance, but the agreement itself determines the actual charging basis.

Find the contractual rate

Do not guess the pence-per-mile rate. Check the agreement for the allowance and excess-mileage wording. Some agreements may have different bands or other conditions, so the tool’s simple projection should be treated as an estimate.

How our projection works

My PCP Check uses your current mileage and progress through the term to project a straight-line end mileage. It then compares that projection with the scheduled allowance and, when you provide a rate, estimates the potential excess-mileage amount.

Worked example

If a 4-year agreement allows 8,000 miles per year, the scheduled allowance is 32,000 miles. A simple projected finish of 38,000 miles is 6,000 miles over. At an illustrative 10p per excess mile, that would be £600. Your agreement’s actual rate and charging rules control.

Mileage is only one return factor

Vehicle condition can also matter at return. Mileage calculations should not be treated as a complete estimate of every possible end-of-contract charge.

What to do if you are trending over

First verify the projection and contract terms. Then compare the likely mileage cost with the other routes available at the end of the agreement rather than making a decision from mileage alone.

FAQ

Does excess mileage automatically apply if I buy the car?

The answer depends on the agreement and route taken; check the lender’s terms rather than assuming the return charge applies identically to every route.

Is My PCP Check’s mileage number guaranteed?

No. It is a straight-line projection based on the figures you enter.

Check your own agreement

The quickest way to make these concepts useful is to compare them with the figures on your own agreement.
