Leasing or a loan: what the decision actually turns on

A loan buys ownership. The bank advances the purchase price, you buy the car, and with the final instalment it is yours with no strings attached. What happens to it afterwards — keep it, sell it, modify it, drive twenty thousand kilometres a year — is nobody else's business.

Leasing buys use for a period. The leasing company stays the owner, you become the registered keeper, and you are not paying for the car but for the value it loses during the term plus interest on the capital tied up in it. At the end you hand back something you never owned.

The distinction sounds academic and is the whole of this piece. It explains why the lease payment on the same car is lower, why a lease carries obligations a loan never has, and why at the end of the term one of them leaves you with a car and the other with an empty parking space.

The payment has three parts, and only the first has anything to do with the car. The amortisation part is the calculated loss in value: acquisition value minus the agreed residual, divided by the number of months. The interest part covers the capital the leasing company has sitting in the car during the term. On top come arrangement and administration costs, often as a one-off fee at the start.

That tells you which levers exist. A high residual lowers the payment because less depreciation is spread across the term — but it moves the risk to the end. A long term lowers the payment too, while costing more interest overall. A down payment reduces the amount to be financed and so shrinks both parts at once.

A lease often does not state an interest rate at all; it hides in the gap between acquisition value, residual and the sum of the payments. A contract that does not disclose it can still be checked arithmetically: add the down payment, every instalment and the residual, compare that against the cash price, and the cost of finance appears as a single figure.

A typical car loan is an annuity loan: the payment stays the same across the term, but its composition shifts month by month. At the start the interest share is large and the repayment share small, because interest is charged on a balance that is still high. Every payment cuts the balance a little, and since the interest share follows the balance, the repayment share in the next payment grows automatically.

In practice: in the first half of the term the outstanding balance falls noticeably more slowly than the number of payments made would suggest. Anyone selling after two years of four has repaid less than half. That is not an irregularity but the shape of the curve, and it is more pronounced the longer the term.

Two rates appear in every loan offer, and only one is usable for comparison. The nominal rate is the bare price of the money. The annual percentage rate folds in arrangement fees, the payment schedule and the timing of charges — it is the figure that makes two offers comparable. Offers without an APR cannot be compared, only guessed at.

Comparing leasing and a loan by the monthly payment is worthless, because the two payments contain different things. It only becomes a comparison over the total outlay for the same period, the same mileage and the same car — with an end-of-term value honestly assumed on both sides.

On a loan that end value is what the car fetches on the market when the term ends. It is an asset and belongs on the credit side of the calculation. On a lease it is worth nothing to you, because it belongs to the leasing company — unless the contract gives you a purchase option at a price below market value.

Because the car belongs to someone else, the contract prescribes how it is to be treated. These rules are not harassment — they protect the calculated residual — but they cost money, and they are not in the monthly payment.

The most expensive item is regularly the combination of mandatory comprehensive cover and a low excess. Anyone used to an older car carrying third-party cover alone tends to underestimate this by more than the payment differs between two offers.

Two curves run alongside each other during a finance agreement: the market value of the car and the outstanding balance of the loan. The market value falls most steeply in the first years; the balance falls most slowly at the start. In between, the car is worth less than the debt secured on it.

As long as nothing happens, this is uncomfortable on paper and irrelevant in practice. It becomes a problem in a write-off or a theft: the insurer pays the replacement value, which is the market value, and the loan remains due in full. You pay the difference for a car that no longer exists.

The answer is GAP cover, which pays exactly that difference. It is often included in a lease and usually absent from a loan. Whether it is worth having depends on the size of the down payment and the length of the term: a large deposit and a short term close the gap by themselves, while full finance over many years opens it wide.

Leasing suits a predictable, even driving pattern and someone who changes cars every three or four years anyway. It suits cars whose depreciation is hard to judge, because the risk of getting it wrong sits with the leasing company — but only where the contract contains no residual value guarantee from the lessee.

A loan suits someone who keeps the car a long time. The expensive part of depreciation falls in the first years; carrying on after that means driving through the cheapest years of a car's life, which a lease never reaches because the term ends first. It also suits irregular mileage, towing, retrofits and anything else a return inspection takes a dim view of.

And there is a third route that appears in no advertisement: buy a used car for cash or on a short loan, one where the steep part of the depreciation curve is already behind the previous owner. For the same monthly outlay you end up with a car you own rather than a return date in the calendar.

Finance contracts get signed at the sales desk, once the decision about the car is long made and nobody has the appetite to read figures. The process is designed for exactly that. The points below can be settled in ten minutes, and they are regularly worth more than haggling over the car itself.

The most effective order is obvious and rarely followed: negotiate the purchase price first, then talk about finance. Anyone who opens with the monthly payment is not negotiating price but term — and a payment can be pushed down almost at will by stretching the term or raising the residual.

You find the cash price by comparing the same car across Europe: same year, same engine, comparable mileage. That figure is the yardstick every finance offer is measured against, and it stays useful even if you end up financing anyway.

Carvexia is not a party to any of these contracts. The marketplace shows listings and prices; the loan, the lease and the insurance are agreed with a bank, a leasing company or a dealer, and their terms are in their documents alone.
