**Choose the term by how long you genuinely need the car, then check the total cost rather than the monthly figure. A longer term almost always costs less per month and more in total. The 3-month minimum suits a need with an end date, a longer term suits a need without one, and mileage is usually the tie-breaker.**

The monthly figure is the wrong thing to decide on. How to work out which term costs less in total, and what changes when the end date is uncertain.

## Start with the need, not the price

The most expensive mistake in leasing is choosing a term to reach a monthly figure. A long agreement taken because it looked cheaper per month, on a need that ended in July, costs more than the short one that would have matched it.

So the first question is not what you can afford a month. It is how long you will actually want this car. If there is a date — a contract ending, a build slot arriving, a season closing — the term should reach it and stop.

If there is no date, a longer term is usually the better buy, because you are not paying a premium for an ending you do not need.

## Do the total, not the monthly

Work it out on the back of an envelope before anything else. Take the monthly figure, multiply by the term, and remember that the month up front is the first of those months rather than an addition to them.

Take the [BMW X5 M Sport](https://performanceandprestige.co.uk/cars/bmw-x5-m-sport): on the 3-month minimum the total is its monthly figure three times over, and doubling the term doubles the total. If your need is four months, ask for both — the 3-month minimum plus the cost of covering the gap, and a four-month term quoted properly — because which of the two is cheaper is not something the monthly figure will tell you.

The comparison only works when both sides sit on the same mileage, the same term and the same inclusions. If they do not, you are comparing two different products and the arithmetic is decoration.

## How does mileage change the answer?

The included allowance is 1,000 miles a month on every agreement, and excess mileage is charged per mile at a rate published on each car's page, 95p to £10 across the catalogue.

That matters more on a short term than a long one, because a long term has more months to absorb a heavy one. A thousand miles over the allowance inside a three-year agreement disappears into the quiet months. Across three months there is very little room for it.

So if your use is uneven — a summer of long journeys, a project two hundred miles away — say so at the quote stage and have the mileage set for it. Mileage agreed in advance is priced into the figure. Mileage discovered at collection is settled per mile, and per mile is always the expensive way to buy it.

## What if the end date is uncertain?

Take the shorter term. The term binds both sides once it is agreed and early termination is not a plan; an extension is a conversation, and a conversation is a much better position to be in than a contract you want out of.

Tell us at the enquiry stage that the end is uncertain. It changes which cars we suggest, because a vehicle with nothing committed after your window is a far better candidate for an extension than one that is already spoken for.

The reverse holds too. If you know the need is long and stable, say that as well — the monthly figure normally improves as the term lengthens, and there is no reason to buy flexibility you will not use.

What you should not do is split the difference by guessing. A term chosen to hedge an unknown date tends to be wrong at both ends: long enough to outlive the need, short enough to need extending anyway.

## The five questions that settle it

Is there a date the need ends? If there is, match the term to it.
What is the total across each term? Not the monthly figure.
How many miles will you really do, and when? Uneven use punishes a short term.
How certain is that end date? Uncertainty argues for shorter, not longer.
Is this the right car for the whole period? A convertible from October is a different proposition from a convertible from April.


If four of the five point the same way, that is your term. If they split, the tie-breaker is almost always the end date rather than the money.

## Does the car itself change the choice?

It does, in two ways that are easy to miss.

The first is practical fit. A car you are unsure about — a low nose in a town full of steep ramps, a firm ride on a long commute, a real-world range on a route without chargers — is an argument for the shortest term. Three months is long enough to find out and short enough to be wrong.

The second is availability. Some cars are easier to secure for a long window and some for a short one, and across the partner-sourced part of the catalogue that is genuinely vehicle by vehicle. Asking what is available from March for three months gets a better answer than naming one car and one term with no room in either.

[Supercar, grand tourer or SUV](https://performanceandprestige.co.uk/guides/supercar-grand-tourer-or-suv-which-to-hire) is the companion question if the car itself is still open.

## What does not change with the length of the term?

Everything about the shape of the agreement. One month up front, then one a month, whichever term you choose. The same 1,000 miles a month. The same delivery, or collection by you, and the same return at the end, anywhere in mainland Britain. The same driver criteria, because those are set against the car rather than the term.

The security deposit does not move with the term either. It is set against the vehicle — from £1,500 to £50,000 across the catalogue — and confirmed in writing for your car before anything is agreed.

The insurance arrangement is confirmed with you before signing in both cases, and it is never something to infer from the length of the term.

## Frequently asked questions

### Is it cheaper to take a longer term and hand the car back early?

No. The term you agree is a commitment for its whole length, so handing a car back early does not shorten it or reduce what is owed. If three months is what you need, take three months.

### Can I start on three months and extend?

It depends on what is committed on that specific car after your window, so raise it at the enquiry stage rather than in the last few weeks. Flagging it early costs nothing and often changes which vehicle we put you in.

### Does a longer term always mean a lower monthly figure?

Normally, on the same car and the same mileage, because the cost is spread across more payments. It is not something we can guarantee on a partner-sourced car, which is quoted against the specific vehicle, so ask for both terms and compare the written figures.

### What happens at the end of the term, whichever you choose?

We collect the car from an address you choose, repeat the condition check and the photographs taken at handover, read the mileage against the allowance, and release the deposit on the timing given to you in writing once everything matches.
