Residual value leases: who pays when the forecast is wrong

The residual value is the leasing company's forecast of what your asset will be worth when the lease ends, and it sets your monthly rental. The higher the forecast, the less of the asset's cost you pay off during the term, so the lower your payment. What decides whether that forecast costs you anything is not how it was calculated, but who is holding it. In the UK, 'residual value lease' is used for two agreements that split that risk in opposite directions: on one the funder has promised the figure and absorbs any shortfall, on the other the shortfall is a bill you pay. Your own agreement is the only place that tells you which one you have.

The HMRC and accounting references on this page were checked on 14 October 2026. The Budget on 28 October 2026 may change how leases are taxed, so check the position again before you sign.

The same two words describe two opposite deals

Two products get sold as a residual value lease, and they are not variations on a theme.

In the first, the funder keeps the risk. Lombard sells an agreement under exactly that name, aimed at high-value specialist equipment, and sums it up in one line on its own Residual Value Lease page: 'Lombard retain the risks and rewards of the asset.' The rentals are 'priced according to the asset's anticipated future value', and at the end you either return the asset for sale or re-hire it. If the machine fetches less than predicted, that is the funder's loss.

In the second, you keep it. Put a residual value inside a finance lease and the exposure travels with it. HMRC is direct about the difference in its VAT manual on leasing cars. On a fully amortised lease, where the rentals cover the asset's whole value, 'it is the lessee who takes the risk on how much the car will be worth on eventual disposal'. On contract hire, which the same manual notes 'is also known as an operating lease', 'it is the leasing company that takes the risk over the eventual value of the car'. That is the difference between a finance lease and an operating lease, and the residual value is where it shows up.

Both are legitimate, and either can be the right one. We don't write leases at iwoca, so we have no stake in which way you go.

How to tell which one you have been offered

The quote usually will not tell you, because it is a monthly figure. The agreement will, and four things in it give the answer away:

• Whether the end figure is described as guaranteed or only as assumed. A guarantee is the funder's promise, so the risk is theirs. An assumption is a pricing input, and the risk is yours.
• Whether there is a clause about making good a shortfall. HMRC defines the instrument, a residual value guarantee, as 'a guarantee made to a lessor by a party unrelated to the lessor that the value (or part of the value) of an underlying asset at the end of a lease will be at least a specified amount'. If you are the party giving it, you are carrying the risk.
• Whether your mileage or your usage is capped, with charges for damage beyond fair wear and tear. A funder keeping the resale risk protects the asset's condition, because it is the one that has to sell it. That is the shape behind business car leasing, where you hand the car back at the end.
• What the document is called. Lombard tells its own customers: 'Your lease will be documented on a Planned Rental Agreement for a Residual Value Lease. If your lease is documented on a Lease Agreement then you have a Lease.' Other funders use other names, but the agreement type is written at the top of the paperwork.

Signing a guarantee is not neutral paperwork, either. HMRC notes that where a guarantee is entered into at inception it 'may make the lease a finance lease'. Give it at the start and you may have changed what kind of lease you have. Give the same guarantee later and the classification does not normally change.

You can't really negotiate the residual itself. It is the funder's own risk position, not a discount it is holding back. What you can change are the inputs behind it, and you can get a second quote.

‍

Where the number comes from, and why you probably can't see it

The funder sets it, for its own purposes. The inputs are the length of the lease, the usage you agree to (mileage on a vehicle, hours on a machine), the specification, the expected wear and tear, and trade data on what similar assets have been fetching second hand.

So it is a forecast rather than a measurement: a professional view of a second-hand market three to five years out, expressed as a percentage of what you are paying today. It isn't exact or scientific, and the whole of your monthly rental is built on it.

The arithmetic is trivial, the original cost multiplied by the residual percentage. Getting hold of the percentage is the problem. UK funders are under no obligation to publish it and most do not, so a finance lease quote often arrives as a monthly figure with the assumption buried inside. That is a real difference from the United States, where consumer car leases quote a residual as standard, and it is why much of the advice on calculating your own residual doesn't apply here.

So work backwards. Ask the funder what end value the quote assumes, in pounds, and what happens if the asset sells for less. A funder keeping the risk will tell you. One passing it to you should be able to point at the clause. Then get a second quote, because the assumed residual varies a lot between equipment finance providers, which means so does your rental.

‍

What the residual value does to your monthly payment

Every pound of value deferred to the end is a pound you are not paying off during the term. It still carries interest the whole time, though, because the funder has still bought the asset.

Take a £60,000 machine on a five-year agreement, nothing paid up front, at an illustrative 9% a year. Assume a residual of 15%, or £9,000, and the rental is about £1,126 a month. Assume 30%, or £18,000, and it drops to about £1,007.

So the higher assumption saves you roughly £119 a month, which is £7,160 over five years. It also costs about £1,840 more in total, because that extra £9,000 sits there accruing interest, and it leaves £18,000 of the machine's value riding on a forecast instead of £9,000. A higher residual buys a lower payment now in exchange for more interest and more exposure later. The figures are illustrative rather than a quote, and your funder's rate and fees will differ.

When the forecast turns out to be wrong

Sooner or later somebody sells the asset, and it fetches whatever the market pays that day. Three things can happen to you.

Nothing. On an agreement where the funder kept the risk, the resale price isn't your business. You return the asset in the agreed condition, pay for any excess mileage or damage, and that is the end of it.

A bill. On a finance lease with a residual you are expected to cover, a shortfall is yours to make good. HMRC's guidance on terminating a finance lease puts it plainly: 'where the asset has a value lower than the terminal rental the lessee's terminal rental will exceed the terminal rebate'. If the agreement assumed £18,000 and the machine sells for £13,000, the £5,000 gap doesn't disappear because the forecast was optimistic. That is the outcome to look for before you sign.

A rebate. The upside travels with the risk too. Where you are carrying it and the asset beats the forecast, most of the surplus comes back to you: HMRC's guidance on finance leases describes the lessee requiring the lessor to sell and 'pay the majority (often over 99%) of the net sale proceeds to the lessee by way of rental rebate'. You usually instruct that sale yourself, as the funder's agent.

What you generally don't get is a right to buy the asset, and HMRC says that is deliberate: a purchase provision can move the capital allowances from the funder to you, 'and so the lessee can't simply acquire the asset at the end of the primary period'. A funder can still choose to sell it to you at market value. An optional final payment that passes ownership belongs to a business contract purchase instead, where the end figure is guaranteed from the outset, or to what happens at the end of each kind of lease, which is worth reading before your term runs out.

How wrong these forecasts get is not a secret. cap hpi, the valuation house funders buy their residual forecasts from, publishes how accurate its own have been: its Future Used Car Market Overview for October 2026 reports that its September 2023 three-year forecasts sat 10.3% above where September 2026 used values actually landed, 'just outside' the plus or minus 5% target it agrees with customers. That is the industry's own figure rather than an official statistic, and it is a fair measure of what you may be carrying. Values also move in clusters rather than one asset at a time: second-hand prices for electric cars and vans are still settling, so a four-year forecast on one is weaker than the same forecast on a diesel.

‍

What counts as a good residual value

There is no benchmark, and anyone offering you one is guessing. The right percentage depends on the asset class, the term, how hard you will work it, and the funder's own read of the second-hand market. A figure that looks generous on a machine tool would be reckless on a laptop.

What you can do is work out which side of the risk you are on, and judge the number from there. If the funder is carrying it, a high residual is good news: a lower rental, and the forecast is their problem. If you are carrying it, a high residual is a lower rental bought with a bigger bet. The question isn't whether the number is high. It's whether your company could absorb the difference if the forecast turned out to be 10% too generous.

Handing the risk over has a price, though, and it isn't only the rental. HMRC's description of how a lessor prices an operating lease notes that the customer may pay what amounts to a higher rate of interest, 'as well as losing any upside on the expected residual value at the end of the lease term'. Certainty costs you the good outcomes as well as the bad ones.

‍

The residual value in your accounts is a different number

The same two words mean something else again in accounting, which is a fair part of why this gets confusing. The standards define residual value, in wording HMRC quotes back at them, as 'the estimated amount that an entity would currently obtain from disposal of an asset, after deducting the estimated costs of disposal, if the asset were already of the age and in the condition expected at the end of its useful life'. Note 'useful life', not 'lease term': it is an estimate about the whole life of the asset, and it feeds depreciation rather than your rental.

Two near neighbours turn up alongside it. Scrap or salvage value is what the asset is worth once it is finished with, usually a much smaller figure. A capital lease is another name for a finance lease. How any of it reaches your accounts changed for periods beginning on or after 1 January 2026, and the accounting treatment of a lease is a subject of its own, and one for your accountant rather than a quote.

‍

If you would rather not carry anyone's forecast

Owning the asset removes the question. There is no residual value in a purchase, so nobody holds a view about what your equipment will be worth in five years except you, and nobody sends you a bill for getting it wrong. Hire purchase does the same job in instalments, ending with a small option-to-purchase fee that passes ownership to your company. A loan does it by letting you buy the asset outright.

An iwoca Flexi-Loan is a business loan with flexible repayment options, and it is one way to do that. You can use a Flexi-Loan to buy or replace a van or other work vehicle, and because it's unsecured, we don't take a charge over it. On a page about who holds the risk in an asset, that is the part worth noticing: the asset is yours from the start and stays outside the finance agreement. Early repayment carries no fee, which is why many of our customers only take out our finance for a few weeks, or even days. We lend to UK limited companies.

Leasing still wins plenty of the time. It is usually cheaper month to month, it keeps a large payment out of this year's cash flow, and on an asset with a short or unpredictable life, paying a funder to carry the resale risk is a sensible thing to buy. The point is knowing that is what you are buying.
