Buy outright, lease for 3 years, then what? Honest comparison needs the same window on both sides. Buy: 25,000 now, keep for 3 years, sell for 15,000 — net cost 10,000 across 36 months = 278/month. Lease: 300/month × 36 = 10,800 with zero at end. In this example lease costs 800 more but saves the upfront capital and the hassle of selling. Neither is always right — depends on cashflow, mileage, and how you feel about always driving something new.

Vehicle-cost comparator.

A worked example

Try the defaults: buy price of 25,000, resale value at end of 15,000, lease monthly of 300, period of 36. The tool returns 800.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Buy Price, Resale Value at End, Lease Monthly, and Period. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.

The formula behind this

Buy net = price minus expected resale. Lease total = monthly × months. Ignores cost of capital locked up in the buy path. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

Using this to think, not predict

Financial plans are wrong by month six — new information arrives and reshapes the picture. The point of running projections isn't to be right in ten years; it's to be less wrong in the decision you're making this week.

What this doesn't capture

Real plans get re-run against new information every year or two. The result here is a reasonable direction, not a destination. Treat it as a starting point for thinking, not a commitment to a specific future.

Example Scenario

Buy vs lease produces a cost comparison based on the inputs provided.

Inputs

Buy Price:25,000 £
Resale Value at End:15,000 £
Lease Monthly:300 £
Period:36 months
Expected Result£800.00

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Sources & Methodology

Methodology

Buy net = price minus expected resale. Lease total = monthly × months. Ignores cost of capital locked up in the buy path.

Frequently Asked Questions

Does this include maintenance?
No. Most leases include maintenance; buyers pay it separately. Add 500-1,500/year to buy path for a fair comparison on older vehicles.
What about mileage?
Leases cap annual mileage. Exceeding the cap is expensive. If you drive heavy miles, buying is usually cheaper over 3+ years.
Are there tax differences?
For personal use, minimal in most jurisdictions. For business use, lease can be fully deductible while buy requires depreciation. Check with an accountant.
What about holding longer?
The longer you hold a bought car, the better buy looks. Cars held 6+ years usually beat leasing on pure cost, provided maintenance does not spike.
