Estimate your UK Vehicle Excise Duty (VED)
Use this calculator to estimate your yearly UK road tax based on registration date, emissions, fuel type, and vehicle class.
Important: This is an estimate for planning purposes and may differ from official DVLA charges, exemptions, or temporary rate updates.
How UK vehicle tax works
Vehicle tax in the UK (often called road tax, car tax, or VED) is based on a combination of factors, including when the vehicle was first registered, its CO₂ emissions, fuel type, and list price. The exact rules have changed several times, which is why many drivers are unsure what they should pay.
This page gives you a practical calculator and a clear explanation so you can estimate your yearly tax before renewal or before buying a vehicle.
What affects your vehicle tax amount?
1) Registration date
The registration date determines which tax scheme applies:
- Before 1 March 2001: tax is mainly based on engine size.
- 1 March 2001 to 31 March 2017: tax is primarily based on CO₂ bands.
- From 1 April 2017 onward: first-year tax is emissions-based, then most cars move to a standard annual rate.
2) CO₂ emissions
Higher-emission vehicles generally pay more, especially in the first year for newer cars. Lower-emission vehicles usually pay less, though policies for electric and low-emission vehicles have changed over time.
3) List price supplement
For many cars first registered from April 2017 onward, an additional charge can apply if the original list price was over £40,000. This supplement typically applies for a limited period in the early years of the vehicle’s life.
4) Vehicle class
Vans and motorcycles often follow different rate structures from cars. That is why this calculator lets you choose vehicle type before estimating your annual tax.

Quick examples
Example A: Typical petrol car (post-2017)
A petrol car registered in 2021 with a list price below £40,000 usually pays the standard annual rate on renewal.
Example B: Higher-value car
If the original list price was above £40,000 and the car is still within the supplement window, add the expensive car supplement to the standard annual rate.
Example C: Older car (pre-2001)
For older registrations, engine size can still be the key factor, so the calculator will ask for cc instead of relying on CO₂.
Tips before you buy a used car
- Check the exact DVLA tax due date and amount before purchase.
- Ask for CO₂ data and original list price (if applicable).
- Factor road tax into your total annual running cost, alongside insurance, fuel, and maintenance.
- Remember that tax rules can change between budget cycles.
