Car Lease vs Buy UK 2026/27 — Compare the Total Cost

The monthly payment is often the first number people compare when deciding whether to lease or buy a car. That is rarely enough. Leasing and buying place different costs and risks in different parts of the agreement: deposit, monthly payments, mileage, servicing, insurance, tax, depreciation, resale value, finance interest and the cost of ending early.

The Car Lease vs Buy Calculator→ compares simplified total costs over selected periods. It can help you test a planned usage pattern, but it is not a finance offer and does not assess whether a vehicle is suitable or affordable. The written lease or finance agreement, the vehicle’s current costs and your household budget are the evidence for a real decision.

This guide explains the UK comparison for 2026/27 without assuming that one route is always cheaper. The best choice can change with how long you keep the car, how many miles you drive, whether you need ownership, how predictable your income is and whether you can absorb an unexpected repair or early-exit cost.

What leasing and buying mean

Leasing normally gives you use of a vehicle for an agreed period and mileage in exchange for an initial payment and regular rentals. Depending on the product, maintenance may be included or purchased separately. At the end, the vehicle is usually returned under the contract terms rather than becoming your asset. Check the exact agreement: products differ, and terminology can be used differently by providers.

Buying means you acquire the vehicle with cash or finance. With a cash purchase, the upfront cost is high but there may be no finance interest. With a personal loan or hire purchase, payments spread the cost and the agreement determines when ownership passes. Personal contract purchase can create a final optional payment and conditions that differ from both a simple lease and an outright purchase.

Do not compare a lease with a finance product only by the monthly figure. Compare the cash flows and the end position at the same date. At the end of a lease you may have a returned vehicle and no asset. At the end of a purchase you may own a car with a resale value, but also face depreciation, maintenance and market risk.

Use the calculator as a total-cost model

Start by choosing the comparison period. A three-year view and a five-year view can tell different stories because the buying option may retain value while a lease may have different rental and renewal costs. Use the same vehicle specification, expected miles and running-cost assumptions where the options are genuinely comparable.

Enter the initial payment, monthly payments, finance interest, fees, servicing, maintenance, tax, insurance assumptions and expected resale value. The calculator’s result is only as good as the inputs. If a lease includes servicing but a purchase scenario does not, the comparison is distorted. If a purchase includes a realistic resale value but a lease return charge is omitted, the result is also distorted.

Run a central scenario and downside cases. Test higher mileage, lower resale value, a repair allowance, a different holding period and an early-exit event. A car decision should survive reasonable changes in assumptions, not just produce a winning result in one precise forecast.

Monthly payment versus total cost

A lease can look attractive because the deposit and monthly rental fit a monthly budget. A finance purchase can have a higher monthly payment but leave an asset at the end. Neither observation establishes the total cost.

For a lease, add the initial payment, every rental, arrangement fee, delivery charge, maintenance cost not included, excess-mileage cost, damage or condition charges and any end-of-term purchase or exit amount. For a purchase, add the deposit, finance payments, interest, arrangement fees, servicing, repairs, tax, insurance and the opportunity cost of capital where relevant. Then subtract the realistic resale value at the comparison date.

The resale value is not guaranteed. It depends on model, age, mileage, condition, demand, accident history, maintenance records and wider vehicle-market conditions. Use a conservative range rather than a single optimistic number.

Mileage is a contract issue

Lease agreements often specify an annual or total mileage. Exceeding it can create a charge, and the per-mile cost may be much higher than the cost of choosing a more suitable mileage allowance at the start. Underestimating mileage because a commute is currently short can create a problem after a job change, family change or longer travel pattern.

Buying avoids a contractual excess-mileage charge, but mileage still affects depreciation, servicing and resale value. A high-mileage vehicle can be harder to sell or worth less. Enter the expected mileage in both scenarios and test what happens if it increases.

Do not assume that returning the vehicle early removes the obligation to pay. Read the agreement’s early-termination terms and ask the provider for a written settlement figure before making a decision to exit.

Condition, maintenance and end-of-term charges

A lease return normally requires the vehicle to meet contract standards for condition and use. Ordinary wear may be treated differently from damage, missing equipment, tyre condition or modifications. The provider’s return guide and contract determine what can be charged.

Buying gives you more control over the vehicle, but you carry the maintenance risk. A warranty may cover some failures and not others. Servicing, tyres, brakes, breakdown cover, MOT testing where applicable and repairs should be included in a realistic annual budget. GOV.UK explains the MOT process and timing; check the current requirements for the vehicle rather than assuming that a newer car never needs planning for testing.

Maintenance included in a lease is not free in an economic sense. It is part of the rental or contract price. Its value depends on the coverage, exclusions, service intervals and the cost you would otherwise have incurred.

Depreciation and residual value

Depreciation is often the largest economic cost of owning a new vehicle. It is the reduction in value between purchase and sale. A buyer absorbs that change directly, while a lease provider estimates residual value when setting the rentals. The lease price may still reflect depreciation, financing, risk and provider margin.

Residual-value assumptions are uncertain. New model releases, used-car demand, mileage, condition, tax treatment and technology changes can alter the resale market. Electric vehicles and conventional vehicles can have different depreciation patterns, but do not rely on a fixed generalisation. Use current comparable listings carefully and treat them as evidence with uncertainty, not a guaranteed future price.

If you buy a vehicle outright, the retained asset has a benefit only if you can sell it at the assumed value and are willing to bear the timing and transaction effort. If you need to keep the vehicle longer, a lower annual cost may emerge after finance is cleared, but repair risk and depreciation continue.

Finance, ownership and consumer protection

Read the finance agreement’s annual percentage rate, total amount payable, deposit, term, optional final payment, ownership condition, settlement rights and missed-payment consequences. MoneyHelper’s car-finance guidance explains why the total cost and ownership outcome should be compared, not only the monthly payment.

The FCA provides consumer information about car finance and complaints. Use regulated firms and keep copies of the agreement, pre-contract information and communications. If a broker or dealer describes a product as “cheap” or “flexible”, translate that description into the actual total amount payable and conditions.

Do not confuse a lease with a finance agreement that ends in ownership. The legal rights, voluntary termination provisions, settlement process and end-of-term options can differ. Ask the provider to explain in writing what happens if you want to end the contract, exceed mileage or return the vehicle early.

Tax, insurance and running costs

Vehicle tax is separate from the finance decision. GOV.UK publishes current vehicle tax rate tables; check the vehicle’s classification, registration details and applicable rate rather than copying an old estimate. Insurance can vary significantly by driver, postcode, vehicle, mileage and cover level. A quote for one car cannot be reused as a general percentage for another.

Fuel or charging cost should reflect realistic mileage and usage. An electric vehicle may have different home, public-charging and energy assumptions from a petrol or diesel car. Include installation or access costs where relevant and test the result if public charging is more frequent than expected.

Company-car tax and business-use treatment are separate questions. A private household comparison should not be mixed with an employer-provided car calculation unless the tax, benefit and ownership assumptions are explicitly modelled. If the vehicle is used for work, check the employer’s policy, mileage reimbursement and tax treatment using current official guidance.

When leasing may fit

Leasing may fit a driver who values a predictable contract, prefers to change vehicles regularly, can estimate mileage accurately and does not need the vehicle as an owned asset. A maintenance-inclusive arrangement may make budgeting easier, although coverage and exclusions must be checked.

Leasing may be less suitable for someone with uncertain mileage, likely job or family changes, irregular income, a need to modify the vehicle, or a preference to keep a car after finance ends. The early-exit terms and return-condition rules should be treated as central, not fine print.

When buying may fit

Buying may fit someone who expects to keep the vehicle beyond the finance period, drives variable mileage, wants control over resale or needs to avoid return-condition rules. Once finance ends, the household may have a lower monthly cash requirement, but the vehicle is still not free: depreciation, repairs, insurance, tax and maintenance continue.

Buying can also be more flexible if plans change, but selling a financed car may require settlement of the outstanding balance. If the car is worth less than the settlement amount, the owner may need to provide additional money to exit. Check the settlement figure before assuming that ownership creates easy flexibility.

A practical decision checklist

Write down:

• the comparison period and expected annual mileage;
• initial payment, monthly payments, finance interest and all fees;
• whether servicing, tyres, repairs and breakdown cover are included;
• vehicle tax, insurance, fuel or charging assumptions;
• lease return standards, excess mileage and early-exit terms;
• purchase finance settlement conditions and optional final payment;
• conservative, central and optimistic resale values;
• what happens if income falls or the car is needed for longer; and
• whether owning the vehicle at the end is important to the household.

Then run the Car Lease vs Buy Calculator→ for more than one holding period. Keep the written lease or finance quote beside the calculation and update the model when a provider changes the terms.

Common mistakes

The most common mistake is choosing the lowest monthly payment. Others include ignoring the initial payment, treating a deposit as a refundable amount, omitting fees, underestimating mileage, assuming all maintenance is included, using an optimistic resale value and forgetting insurance or vehicle tax.

Some buyers compare a new leased vehicle with an older owned vehicle without accounting for different reliability and specification. Some lessees accept a low mileage allowance and then pay for extra miles. Some owners assume the car’s resale value will cover the outstanding finance. All of these errors can reverse the apparent winner.

Frequently Asked Questions

Bottom line

Lease versus buy is a total-cost and flexibility decision, not a monthly-payment contest. Include the initial payment, all rentals or finance payments, fees, maintenance, mileage, tax, insurance, energy or fuel, early-exit conditions and the end value of the vehicle.

Use the Car Lease vs Buy Calculator→ to test comparable scenarios, then read the full written agreement. MoneyHelper, FCA and GOV.UK provide general consumer and vehicle guidance, but only the provider’s current terms and your household budget can establish whether a particular arrangement is affordable and suitable.
