How it works
The quick overview
If you've landed here looking for a car depreciation calculadora, good news — Car Depreciation calculadora runs in your browser, shows the working, and doesn't try to sell you a spreadsheet template.
Fuel costs quietly rival insurance over a few years; worth running. Write down the mileage, not the odometer total — then work it out and the rest of this page explains what the answer means.
Project a car’s resale value year by year using straight-line or declining-balance depreciation and real market rates.

Scenarios where Car Depreciation calculadora pays off
Car Depreciation calculadora is aimed at people arriving with questions like these:

- "How to calculate car depreciation"
- "Car depreciation example"
When it isn't the right tool
Every tool has an edge where it stops being the right answer. Car Depreciation calculadora is no exception:
- For legally binding tax or medical decisions — cross-check with HMRC, NHS or a qualified professional.
- For very large or very small extremes the rounding error outgrows the useful precision.
- When the underlying rate or threshold has changed since the page was last reviewed — always verify with the primary source.
- When the input you have is already a derived figure (net of something) — feeding it in as "gross" will double-subtract.
Where this calculation usually breaks
Every time you work it out for a new scenario, one of these creeps in — it's worth knowing them ahead of time.
- Mixing up units — grams in one field, ounces in another, then wondering why the answer is off.
- Treating a percentage as a whole number. 20% means 0.20 in the maths, not 20.
- Rounding at every step. Keep four decimals internally and only round the final number.
- Using last year's thresholds. If the page isn't dated, assume it's stale and check GOV.UK.
- Reading a tool like this as advice. It is maths, not a decision — the decision is still yours.
The sources behind the numbers
Where the maths needs an external authority, we cross-check against:
- HPI
- FIPE
- Autotrader
