What Is Optional Final Payment?

What the optional final payment is, in plain English

The optional final payment is the large deferred lump sum on a PCP that you pay only if you decide to keep the car — equal to the Guaranteed Minimum Future Value.

On a Personal Contract Purchase you don't spread the whole car price across the term. Instead, the lender predicts the car's minimum value at the end and sets that figure aside as the optional final payment. Your monthly payments cover only the depreciation in between — the drop from the car's price today down to that guaranteed end value.

Because that final lump sum is optional, the deal gives you three endings. You can pay it and own the car, hand the car back within the mileage and condition terms and owe nothing more, or part-exchange any equity above it into a new agreement. The optional final payment is the price tag on the first of those three choices.

How the optional final payment works — the mechanics

The optional final payment is set at the start of the PCP from the car's price, the term and your agreed mileage, and it's the figure the lender guarantees the car will be worth at the end.

Three inputs set the figure. A higher car price raises it; a longer term usually raises it (the car is newer at the end relative to the schedule); and a higher agreed annual mileage lowers it, because the car is expected to be worth less. The lender carries the depreciation risk on that guaranteed portion — if the car is worth less than the optional final payment at handback, that's the lender's loss, not yours.

Deferring this lump sum is what makes PCP monthly payments low. On the same car, PCP runs roughly £140 a month below HP because you're not paying off the optional final payment during the term — you're carrying it to the end. The trade-off is that if you do want to own the car, you pay interest on that deferred sum for the whole term, so the total cost to own exceeds HP.

You can settle the optional final payment three ways: pay it in cash, refinance it with a new loan (which adds more interest), or — if you've reached 50% of the total amount payable — hand the car back under voluntary termination instead. Most drivers simply roll the equity above the optional final payment into a fresh PCP on a newer car.

The optional final payment is fixed at the start, but your relationship to it changes as the term runs. Two things move: the car's actual market value, and your settlement figure (which includes a rebate on interest if you end early). If the car holds its value better than the lender forecast, the gap between market value and optional final payment widens in your favour — that's equity you can deploy. If it depreciates harder than expected, the guaranteed optional final payment becomes your safety net, because you can hand the car back and the lender absorbs the shortfall. Either way, the OFP is the benchmark against which your end-of-deal choices are measured.

Optional final payment vs balloon vs GMFV

Optional final payment, balloon payment and GMFV are three names for the same final lump sum on a PCP — the figure you pay only if you keep the car.

Pay the optional final payment, hand back, or part-exchange?

You have three endings on a PCP: pay the optional final payment to own the car, hand it back within the terms, or use any equity above it towards a new deal.

A worked example

On a £20,000 car with a £8,000 optional final payment, the monthly is about £314, and paying that £8,000 at the end takes the total to own to around £25,086.

Of that £25,086 total, roughly £5,086 is interest — the cost of deferring the optional final payment across the whole term. Compare that with HP on the same car at about £23,695 total: paying the balloon to own makes PCP the more expensive route by roughly £1,400 in this example.

If the car is worth £9,500 at the end — above the £8,000 optional final payment — you have £1,500 of equity to put towards a new deal, which softens the higher total. If it's worth only £7,000, you can hand it back and the lender absorbs the £1,000 shortfall against the guarantee.

When and why the optional final payment matters to a UK driver

The optional final payment decides your monthly payment, your total cost to own, and the equity you have at the end of a PCP — three of the biggest money levers in the deal.

It matters at the start because it sets the monthly. A lender that offers a higher optional final payment quotes a lower monthly, which looks attractive but raises the lump sum you'd need to own the car — and the interest you pay on it. Always read the total amount payable alongside the monthly, not the monthly alone.

It matters at the end because it's the hinge between your three options. If the car's market value sits above the optional final payment, you have equity; below it, handing back protects you. Knowing the figure in advance — and tracking the car's value against it — lets you choose the cheapest ending rather than defaulting into whatever the dealer suggests.

What's fixed and what changes around the OFP

The optional final payment itself is fixed at the start, but the car's market value and your settlement figure both move — and the gap between them decides which ending is cheapest.

Only the optional final payment is locked. Everything else — the car's value, your settlement, how much of the total you've paid — shifts month by month. That's why the smart move near the end of a PCP is to get a live valuation and a settlement figure at the same time, then compare both against the OFP. The arithmetic tells you which of the three endings (keep, hand back, part-exchange) actually costs you least, rather than guessing.

If you're partway through the term, the same comparison tells you whether voluntary termination is on the horizon. Once your total paid (deposit plus monthly payments, plus the OFP if you were to pay it) reaches 50% of the total amount payable, you can hand the car back under Section 99 of the Consumer Credit Act 1974 with nothing more to pay — a useful exit if your circumstances change and the OFP looks unaffordable.
