What Is GMFV in PCP Car Finance? Guaranteed Minimum Future Value Explained

GMFV, or Guaranteed Minimum Future Value, is the amount your lender estimates your car will be worth at the end of your PCP finance agreement. It plays a big role in deciding how much you’ll need to pay if you choose to buy the car at the end.

In the UK, you might also see it called GFV (Guaranteed Future Value) and related terms like  “balloon payment”, or “optional payment”. Balloon payment (or optional payment) is the amount you pay at the end of a PCP agreement if you want to keep the car. This figure is based on the GMFV, which is the lender’s estimate of the car’s value at that point. In practice, the optional payment is usually set equal to the GFV.

GMFV influences your monthly payments, your car’s equity, and your end-of-agreement options.

In this guide, we’ll explain how lenders set GMFV, and why it matters. You’ll learn how it affects what you pay each month, what your three options are when the deal ends, and how to spot (or even build) equity in your car.

We’ll also share practical tips to help your car hold its value, so you can stay in control and avoid any nasty surprises at the finish line.

Key takeaways

• GMFV is your car's guaranteed value at the end of your PCP agreement and also sets your optional final payment amount
• A higher GMFV typically means lower monthly payments, but a larger balloon payment to keep the car
• You have three choices at the end of your PCP finance agreement: return the car, pay the balloon payment (based on the GMFV) to own it, or part-exchange for a new vehicle
• Positive equity happens when your car’s worth is more than the GMFV, providing a deposit for your next car
• Choosing a suitable term length, realistic mileage and maintaining your car helps beat the GMFV

What is GMFV (Guaranteed Minimum Future Value)?

GMFV (Guaranteed Minimum Future Value) is the lowest amount your lender guarantees your car will be worth at the end of a PCP agreement. Think of it as a promise: it’s not your deposit, not equity, and not typically the real market value. It’s simply the figure your lender locks in if you hand the car back or decide to buy it.

Lenders predict how much your car will depreciate over the contract period and then set the GMFV slightly below that forecast. How do they do that? They look into their crystal ball (okay, data collected from CAP, Glass’s Guide, and their own forecasts) and work out how much your car will lose value over time. GMFV is usually fixed, so you can’t tweak it yourself.

Factors that affect your GMFV include:

• Contract length: Longer terms mean more depreciation, lowering GMFV
• Mileage allowance: More miles = more wear, so GMFV drops
• Car model: Popular models with strong resale value tend to have higher GMFVs
• Market trends: Historical depreciation rates and current market forecasts all play a part

Side note: Deposit and APR shape your repayments, but don’t change the GMFV itself, which is set by the lender. And don’t forget, fees for extra mileage or damage sit outside the GMFV figure.

But here comes the good bit. If your car’s value drops below the GMFV at the end, you don’t cover the shortfall. Hand it back and walk away. There’s no sudden bills, as long as you’ve kept within your agreement – that means sticking to the mileage limits and fair wear and tear rules.

That’s the beauty of GMFV: it gives you certainty and options, whether you’re returning the car, buying it, or using any equity to upgrade.

How GMFV impacts your monthly PCP payments

A higher GMFV lowers monthly payments but raises the balloon payment if you want to keep the car. Your monthly PCP bills pay off the gap between what you paid for the car and the GMFV, plus interest.

If you can't afford the optional final payment, or you don't have any positive equity, you may want to refinance your car. Or you could start a whole new PCP agreement.

Let’s take a £20,000 car as an example.

• With a £10,000 GMFV, your monthly payments cover £10,000 of depreciation.
• With a £12,000 GMFV, they cover only £8,000.

The higher GMFV means lower monthly payments, but a bigger final balloon payment of £12,000 if you want to keep the car.

Lenders will set GMFV differently based on their data, risk appetite and business goals. Car-makers who also offer finance often set higher GMFVs, which might make their cars look cheaper each month. Meanwhile, independent lenders might be more cautious. This could mean higher monthly payments, but a more realistic end value.

When you’re comparing car finance deals, don’t just stare at the GMFV. Check the full picture, including: 

• the total amount you'll pay,
• APR,
• any deposit contributions,
• fees, and
• the final balloon payment. 

The key thing is to look at the whole offer, not just the GMFV or the monthly payment. A deal with a high GMFV might look great because of the low monthly cost. But the cheapest monthly payment isn't always the best value overall.

Your 3 options at the end of a PCP contract

Based on your equity, you can return the car, keep it by paying the GMFV, or part-exchange. Each option needs serious consideration depending on your car's value compared to the GMFV, your budget, and whether you want to keep driving this car.

Each choice has its own steps and timings. Give your lender a shout 8 – 12 weeks before to lock in your next move. They'll set up an inspection if you're returning the car. Or they'll give you a settlement figure if you want to buy it. They can also help sort out a part-exchange with a dealer.

The paperwork is different for each option. If you return the car, make sure your payments are up to date and you have your V5C document handy. To buy the car, you'll need to pay the balloon payment plus an "option-to-purchase" fee. If you part-exchange, the dealer can do most of the paperwork. But make sure you get everything in writing. This should show your car's valuation and how your equity is being used.

One important thing that is often overlooked is the mileage limit. You could face charges for going over your mileage limit when you return the car. Also, there might be penalties for unexpected damage. You'll want to think about the true cost of refinancing if you can't afford the optional final payment. Knowing these risks helps you get ready financially.

1. Return the vehicle on a PCP agreement

Returning your car means handing it back without further payments, provided it meets fair wear and tear standards and stays within the agreed mileage. The lender inspects for damage beyond normal use and checks your recorded mileage against the contract limit.

It’s a good option if the car’s value has dropped below the GMFV. You may have heard of this as “negative equity”. It also makes sense if you don't need a car anymore, or if you want to try a different type of car finance. 

Before returning the car, give it a good clean inside and out. It's also worth fixing small issues like stone chips or little scratches. Knowing the BVRLA standards helps you know what to expect. 

Minor dents and a bit of wear inside are usually fine. But bigger things like deep scratches, cracked glass, or burns and tears on the seats will likely lead to charges. A missing service history can also cost you. These charges can be anything from £50 to a few hundred pounds for each problem.

2. Pay the GMFV to own the car

Keeping your car requires paying the GMFV based-balloon payment. There might be an option-to-purchase fee, ranging from £1 to £500. Ask your lender for a settlement figure. There you’ll see the exact amount needed, including any fees or outstanding charges.

You can pay the balloon payment by taking out a new HP car loan. It's smart to compare financing offers and APRs carefully. Remember to look at the total amount you'll pay back, not just the monthly cost.

Buying the car can be a good move if you've looked after it well and you know its full history. Popular models that have been looked after are often cheap to keep on the road.

Find out if refinancing your current car finance could be a good option for you.

3. Part-exchange for a new car

Part-exchanging uses any positive equity as a deposit on your next vehicle. This is your car's current value minus the settlement figure. At the end of a PCP, the settlement figure equals the GMFV and the option to purchase fee. Mid-contract, the settlement figure is different and might not match the GMFV. 

The dealer values your car, settles your existing finance, and applies any surplus towards your new agreement. This option is a popular choice for drivers. When most drivers part-exchange their car at the end of the deal, they're basically rolling any equity into a new PCP contract.

Part-exchanging is your best bet when you have positive equity and you're ready to upgrade to another car. Popular models in good nick often give you equity for your next deposit. 

But watch out for dealers who mix your equity into their discount offers. Always talk about the new car's price separately from your part-exchange value.

Ask for clear paperwork that shows all important details, such as:

• Your car's trade-in value
• How much is left on your current finance
• Your calculated equity
• And how that equity is being used on the new deal.

Understanding vehicle equity with practical GMFV scenarios

Your equity will decide whether you walk away, break even, or profit. At the end of your PCP contract, there are three possible equity situations, depending on whether you have positive or negative equity.

Positive equity

Positive equity is when your car is worth more than the settlement figure (usually GMFV and option to purchase fee), giving you extra value. Let's look at an example. Imagine your car has an £8,000 GMFV and a total settlement of £8,200. If the car is now worth £9,500, you have £1,300 of positive equity to use as a deposit. 

Break even

When you break even, the market value is about the same as the settlement amount. With the same example, if the car is now worth £8,200, you break even. You don't have any equity, but you don't owe anything either.

Negative equity

With negative equity, your car's value is less than what you owe. The GMFV protection is there to limit how much this affects you. Using the same example, if the car is only worth £7,000 instead of its £8,000 GMFV, you're in negative equity. But you can just return the car without paying the difference, as long as it's in good condition and within the mileage limit.

The GMFV protection means you won't be out of pocket if your car's value drops suddenly, as long as you've met the contract's terms. GMFV protection only kicks in at the very end of your PCP contract. If you choose to settle your agreement early or mid-term, the guaranteed value no longer applies, and you could face negative equity if the car's market value is low.

What to do when your car is worth more than the GMFV?

If your car’s market value is higher than the settlement figure (including the GMFV), you’ve got positive equity. You can cash this in by either part-exchanging the car or selling it privately and using the extra value to settle your finance.

How to get a fair valuation

Start by getting multiple quotes from dealers, car buying services, and even online tools. You can use these valuations to compare offers and strengthen your negotiating position.

Always ask the dealer to break down the numbers. You want a clear, written summary showing:

• Your car’s trade-in value
• Your current settlement figure
• The final equity is being put towards your new deal

Why timing matters

Sell before a big model update or new number plate release; these can dent your car’s value. Cars in good condition sell best during high-demand seasons (spring for convertibles, winter for 4x4s), and dealers often pay more just before new registrations launch.

Avoid hidden equity traps

Some dealers might try to bury your equity in the deal. Always negotiate the price of your next car before talking about part-exchange. That way, you’ll see exactly what your current car is worth, and where that equity is going.

What to do when your car is worth less than the GMFV?

If your car’s market value is lower than the GMFV when your PCP contract ends, don’t panic. That’s exactly what the “guaranteed” bit protects you from. You can hand the car back without paying the shortfall, as long as you’ve stuck to the contract terms. You’ll only face charges for excess mileage or damage beyond fair wear and tear.

Can I still keep the car?

Yes, but you’ll need to pay the full GMFV, even if the car is worth less at that point. This is a personal choice, and it’s up to you whether keeping the car is worth the extra cost.

What if I’m in negative equity mid-contract?

If you're considering early settlement mid-term when your car is worth less than the settlement figure, get quotes for both the settlement amount and current market value. You’ll need to either pay the shortfall upfront or roll it into a new finance deal. Early settlement during negative equity rarely works in your favour unless your situation has changed. For example, if you need a different car or want to reduce monthly costs.

How to help your car's value exceed the GMFV

Maintaining a complete service history, keeping the car in excellent condition, and choosing popular car makes and models help maximise resale value above the GMFV. Small investments in care and maintenance often pay back multiples in retained equity.

Service your car

Service your car as scheduled, preferably at main dealers or approved specialists. Keep all paperwork, stamps, and receipts. A missing or incomplete service history can knock hundreds off your car's value. If you're handy with basic maintenance, you can still do oil changes and minor jobs, but make sure the important services are done by professionals.

Regular maintenance checks

Basic maintenance like keeping tyres in good condition, fixing minor scratches promptly, and regular cleaning all contribute to better valuations.

Keep to mileage limits

Choose realistic mileage limits upfront rather than hoping you'll drive less. It's usually much cheaper to buy extra miles at contract start than pay excess charges later. Calculate your annual driving, including commutes, weekend trips, and holidays. 

Choose a popular model

Popular colours, sensible engine choices, and desirable options help hold value. Avoid very high-performance variants or niche specifications that appeal to limited buyers. 

Time your contract

Timing your contract end can affect value, too. Spring is often better for convertibles, while 4x4s sell better before winter. Avoid major model updates or new registration periods when possible, as these can temporarily reduce demand for older stock. 

Conclusion

GMFV shapes your entire PCP finance, from monthly payments to end-of-agreement options. Understanding how it works helps you decide on your best route for your agreement.

Your end-of-contract options each work differently depending on whether you have positive equity, break even, or face negative equity. The GMFV protects you from market downturns, while positive equity gives you a valuable deposit contribution for your next car or reduces the cost to keep your current one.

Smart choices at the start of your contract set you up for success later. Choose realistic mileage, maintain your car well, and compare offers based on total cost rather than just monthly payments. Remember that, while not negotiable, GMFV can vary between lenders, so shopping around pays off.

Eight weeks before your finish date, grab a few valuations so you know whether you’re sitting on equity or cruising into a return. This knowledge puts you in control of the decision.

GMFV shields you from market dips. Just stick to your mileage and fair-wear-and-tear limits. Plan your mileage, keep your service history tidy, and you’ll finish your PCP with options and maybe extra cash in your pocket.
