Buying a car outright, signing a lease agreement, or financing through PCP — the choice determines not just your monthly cash flow but your total cost of ownership over the life of the deal. Each path has a different trade-off between upfront cash, flexibility and long-term value.
This 2026 guide breaks down how each option works, what you give up and when each makes financial sense, so you can pick the right one for your budget and driving habits.
Buy vs lease car: the core difference
When you buy a car you own it — no mileage limits, no end-of-term bill, and no requirement to hand it back. You do carry the full depreciation hit, typically 15–25% in year one and about half the car's value over five years.
A lease (or PCP, which is a form of finance) is closer to renting. You make fixed monthly payments for a set term, usually with a mileage allowance and an option to buy the car at the end. The monthly payments are lower because you are only paying for the depreciation during the lease period.
Buying and holding for 5+ years usually wins on total cost; leasing often wins on monthly cash flow.
PCP explained: how it actually works
PCP (Personal Contract Purchase) is a hire-purchase agreement with a twist. You put down a deposit, make monthly payments for 2–4 years, and at the end you either return the car, part-exchange it, or pay a final 'balloon' payment to own it outright.
The monthly payments are typically lower than a standard loan because they are based on the car's projected depreciation over the term, not its full value. But you never own the car unless you pay the balloon — and if your mileage exceeds the agreed allowance, you pay excess charges.
Car finance comparison: total cost and flexibility
Buying outright is almost always the cheapest way to have a car for the long term, because you avoid interest charges entirely. The trade-off is a large upfront outlay and carrying the full depreciation yourself.
Leasing and PCP are cheaper month-to-month but more expensive overall, because you are always paying for the steepest part of the depreciation curve — the first few years when a car loses the most value. If you plan to keep cars for 5+ years, buying wins.
Mileage limits, wear and end-of-term costs
PCP and lease agreements come with strict mileage limits — typically 10,000 to 12,000 miles a year. Exceed that and you pay per extra mile at the end. Wear and tear is judged against the finance company's standards, and dents, scratched alloys or worn seats can trigger charges.
Buying outright has no such restrictions. Drive as much as you like, modify the car, sell it early — you answer to no one. The only penalty is the market value when you do sell, which is the same depreciation cost you would face on any path.
| Option | Monthly cost | Total cost | Flexibility | End result |
|---|---|---|---|---|
| Buy outright | High (loan if borrowed) | Lowest over 5+ years | Full | You own it |
| PCP | Low | Higher over 5+ years | Low (mileage/condition limits) | Return, exchange or pay balloon |
| Lease | Lowest | Highest | Very low | Must return |
When buy vs lease car makes sense in 2026
Buy if you keep cars for five years or more, drive irregular mileage, or want the freedom to modify, sell or keep the car indefinitely. The total cost of ownership is lowest when the depreciation is absorbed over a long ownership period.
Lease or use PCP if your cash flow needs low monthly payments, you drive a consistent mileage within the allowance, and you like having a new car on warranty every few years. The trade-off is that after 3–4 years you have nothing to show for it.
Lease vs buy: run your own numbers
The answer depends on how long you plan to keep the car, your tolerance for monthly payments versus total cost, and whether you want to own at the end. The calculators below let you enter your own deposit, term, interest rate and mileage to see which path is cheaper for your exact situation.
Whatever you choose, make sure you have budgeted for VED, MOT, fuel and insurance on top — those running costs are the same regardless of how you finance the car.

Frequently asked questions
Is it cheaper to buy or lease a car in the long run?
Buying outright is almost always cheaper over a 5+ year ownership. You avoid interest charges and you own the asset at the end. Leasing always costs more in total because you repeatedly pay for the steepest part of the depreciation curve — new car, return, new car.
What is a balloon payment in PCP?
The balloon payment is the lump sum you can optionally pay at the end of a PCP agreement to take ownership of the car. If you do not pay it, you hand the car back and walk away — but you have never owned it. The balloon is typically 40–60% of the car's original price.
Can I go over the mileage limit on a PCP or lease?
You can, but you pay excess mileage charges at the end — usually 6–15 pence per mile over your agreed allowance. If you regularly exceed the limit, buying outright is cheaper because there are no mileage penalties.
What happens if I want to exit a PCP early?
You can usually settle the outstanding finance early, but you will owe the remaining payments plus any early termination fee. The amount is often substantial, which is why locking in the right term up front matters more than a low monthly payment.
Do I still pay VED and MOT if I lease a car?
Yes. Road tax (VED), the MOT and insurance are your responsibility even on a lease or PCP. The finance company will usually require you to keep the car taxed and the MOT current, and some will insist you use a main dealer for servicing to maintain the warranty.
