Calculate Vehicle Excise Duty (VED/road tax) based on fuel type and CO2 emissions.
Pick first registration date
Choose pre-March 2001 (engine-size based), March 2001-March 2017 (13-band CO2), or April 2017+ (first-year scaled + £195 flat from year 2). The calculator picks the right scheme.
Enter CO2 emissions or engine size
For 2001+ cars enter CO2 in g/km from the V5C registration document. For pre-2001 cars enter the engine size in cc. CO2 figures are on the brochure and V5C log book.
Add list price (if relevant)
For cars registered from April 2017 with list price £40,001+, tick the Expensive Car Supplement box. List price means manufacturer’s RRP including options, not the discounted invoice price.
Select fuel type
Choose petrol, diesel (RDE2-compliant diesel from April 2018 onwards pays petrol rates; older diesel pays a surcharge in year 1), hybrid (alternative fuel discount £10/year), or electric.
Read year-by-year cost
See first-year VED, years 2-6 standard rate (plus supplement if applicable), and year 7+ rate. Use 6-yearly total for comparison shopping — high CO2 cars cost £4k-£10k+ in VED over the first six years.
How the Vehicle Excise Duty expensive car supplement works in 2026/27, which cars it applies to (including electric vehicles), and how much it adds to the annual bill.
