Enter your vehicle’s UK registration number to estimate the annual road tax (VED) cost. This calculator provides an estimate based on typical 2025 UK tax rates. For precise rates, verify with the official GOV.UK vehicle tax service.
Understanding your road tax obligations in the UK is essential whether you’re buying, selling, or simply keeping your vehicle legally on the road. The Road Tax Calculator by Registration is a quick and efficient way to check how much Vehicle Excise Duty (VED) you owe—using just your number plate.
A UK road tax calculator allows drivers to check their road tax instantly by entering the vehicle registration number (VRN). It connects with the DVLA database to retrieve real-time vehicle details like fuel type, CO₂ emissions, engine size, and registration date. Based on this data, it calculates your annual VED (Vehicle Excise Duty).

Tax Estimate
Based on the type of vehicle and CO₂ emissions, your road tax amount is calculated according to current UK tax bands.
UK road tax (VED) is based on:
| Vehicle Type | Tax Basis |
|---|---|
| Petrol/Diesel | CO₂ emissions (g/km) |
| Hybrid | Reduced rate based on emissions |
| Electric (EVs) | £0 tax (until April 2025) |
| Older Cars | Engine size (pre-2001 vehicles) |
Newer cars (registered after April 2017) pay a flat standard rate after the first year, with an additional charge for cars over £40,000.
Let’s say your vehicle’s registration number is AB12 CDE. You enter this into the calculator, and it finds:
Make: Ford
Model: Focus
Fuel: Petrol
CO₂ Emissions: 125 g/km
First Registered: 2021
Your Estimated Road Tax:
First Year: Based on emissions
Subsequent Years: £190 standard rate (as of 2025)
Electric vehicles (EVs) will no longer be exempt from road tax starting April 2025.
VED bands are reviewed annually and may change with each budget.
Always double-check the final amount on Gov.uk before making a payment.
