Quick answer: Road Tax Calculator (UK)
Simplified DVLA-style year-one and standard rates from fuel, CO₂ band, or legacy engine cc rules.
Example: Petrol 2019 car at 130 g/km might sit in a mid band with six-month option math shown.
Calculations follow the documented formula on this page; rounding and input units can change the last digit—treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
What this calculator does
- Road Tax Calculator (UK)
- Illustrative VED bands for petrol/diesel/EV - simplified 2024/25 style.
Post-2017 CO₂ tables are approximated; luxury supplement years and exact g/km breakpoints need gov.uk confirmation.
Rough first-year and standard rates from CO₂ (g/km) for post-2017 cars and a flat band for older placeholders. Not DVLA official output.
Inputs on this page: First registration year, Fuel type, CO₂ emissions (g/km), 0 if unknown, Engine size (cc) pre-2001 only, else 0. Assumptions stay visible so you can reproduce the figure elsewhere.
When to use it
- Use Road Tax Calculator (UK) when you need a transparent UK road tax calculator answer before you commit numbers to a spreadsheet, invoice, or conversation.
- Reach for it when you already know (or can estimate) First registration year and want the dependent result without rebuilding the formula by hand.
- Skip it when you need certified advice, signed-off payroll, or a lender’s official quote—those require the primary institution’s systems.
Key takeaways
- EVs still have annual VED after year one in many cases - check current law.
- Classic/historic vehicle rules differ - this tool targets mass-market cars.
- SORN saves tax but not insurance obligations.
How to use this tool
- 1Enter registration year and fuel.
- 2CO₂ drives most modern bands; EVs use a zero-emissions path in this model.
- 3Confirm on GOV.UK before you tax a vehicle.

Key formula explained
How the calculation works
The Formula
Band lookup from registration era, fuel, CO₂ or engine cc per simplified DVLA-style tables- First registration year: the value you enter for reg year.
- Fuel type: the value you enter for fuel type.
- CO₂ emissions (g/km), 0 if unknown: the value you enter for co2.
- Engine size (cc) pre-2001 only, else 0: the value you enter for engine cc.
