Assumptions

True monthly cost ≈

$635 /month

The loan payment badly understates the real cost — running costs add about 43% on top. The levers: revisit the insurance/fuel/maintenance assumptions, or consider a less expensive car.

Loan payment $365
Running costs / month $270
Estimated depreciation over the term $12,238
Total paid over the term $42,099

Estimates based on the assumptions above — real offers will differ.

How to Read Your Result

Four things worth understanding before you sign a finance agreement.

The loan payment is not the true cost Insurance, fuel or energy, and maintenance sit on top of the finance quote. The chart shows how much of the true monthly cost each one adds.
Compare loan-only to true cost The comparison bar makes the gap explicit — a smaller loan payment can still mean a larger monthly outlay once running costs are added.
Running costs are your assumptions Insurance, fuel, and maintenance are editable chips, not researched averages — put in your own numbers or quotes for an honest answer.
Depreciation is real but not a monthly bill The estimated depreciation stat shows value lost over the term — it matters at resale, even though it is not cash you pay each month.

What This Tool Does and Doesn't Do

The loan maths is standard amortization, and the running-cost figures are exactly what you type in — nothing is estimated for you behind the scenes. Everything runs entirely in your browser. Nothing you type is sent anywhere unless you press "Explain my numbers", and even then only the figures go, never your name or contact details.

What it can't do is quote you insurance, fuel prices, or a finance rate. Those vary by place, by car, and by your own driving. Treat the result as a well-informed estimate that tells you which questions to ask.

Important: This is educational information, not financial advice. Confirm the figures with a qualified adviser, insurer, or lender before you commit to anything.
