April 13, 2026 in United Kingdom — Working out how much road tax you owe in the UK has never been easier with a car tax calculator. Whether you are buying a new car, checking VED rates for a used vehicle, or planning your next purchase, this guide explains exactly how to use a car tax calculator UK in 2026 and what information you need.

How to Use a Car Tax Calculator UK

A car tax calculator takes the guesswork out of Vehicle Excise Duty (VED) estimates. Simply enter your vehicle's CO2 emissions figure — found on the V5C logbook or via the GOV.UK vehicle enquiry service — and the calculator returns your exact first-year and annual road tax rate.

For the most accurate car tax estimate, you also need the vehicle's fuel type (petrol, diesel, electric, or hybrid) and its first registration date. Cars registered from April 2025 follow the new first-year graduated rates, while earlier registrations use a different calculation method.

Car Tax Rates 2026: What the Calculator Shows

  • 0g/km (electric) — First year £0, then £10 annually for years 2-6
  • 1-50g/km (plug-in hybrid) — First year £10, then £50 annually
  • 76-90g/km — First year £130, then £50 annually
  • 131-150g/km — First year £205, then £190 annually
  • 226-255g/km — First year £1,565, then £190 annually
  • Over 255g/km — First year £2,605, then £190 annually

What Affects Your Car Tax Calculation

The two key factors are CO2 emissions and first registration date. For vehicles registered from April 2025, first-year rates are graduated across 20 bands. For earlier registrations, a different table applies. Fuel type also matters — electric vehicles and alternative fuel vehicles receive favourable rates.

Car Tax Calculator vs DVLA Check

Use the car tax calculator to estimate costs before buying. Use the DVLA check to verify a specific vehicle's actual tax status. The calculator gives a theoretical rate; the DVLA check gives the actual registered rate for a specific registration number.
