Quick Reference
How this calculator works
This tool uses the petrol-car engine-capacity schedule and shows an annual estimate rounded to the nearest dollar. The displayed bands and calculation share the same effective-dated database rules.
Find the band containing the engine capacity, then add its base amount to the per-cc amount above the previous band limit. The stored annual coefficients already include the applicable adjustment factor; do not multiply the result again.
Vehicle age does affect the amount payable: cars older than ten years can attract an age surcharge. This tool shows the base schedule before that surcharge. Diesel, hybrid and special vehicle schemes may require additional or different calculations.
Fully electric cars use motor power and an additional flat component. Use the EV vs Petrol calculator for that schedule; petrol engine capacity is not a substitute for EV motor power.

Frequently asked questions
- Does this tool include tax for an older car?
- The result is the petrol-car base schedule. An age surcharge may apply after ten years and is excluded from this estimate.
- Can I enter motor power instead of engine capacity?
- No. This petrol-car tool takes engine capacity in cc. The EV vs Petrol calculator uses the separate electric-car motor-power schedule and flat component.
