How it works
What this calculadora actually does
Most Vehicles tools bury the calculation. UK Road Tax (VED) calculadora shows it. Punch in your figures, read the working, share the URL if you need a second opinion.
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.
UK Vehicle Excise Duty (VED) depends on registration date and CO₂: new cars pay a first-year rate tied to CO₂, then a flat standard rate (£180 in 2024/25; updated annually), plus a £410 luxury supplement on list-price >£40,000 for years 2–6.

When it isn't the right tool
Every tool has an edge where it stops being the right answer. UK Road Tax (VED) 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.
Mistakes we see over and over
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:
- GOV.UK
- DVLA
