What your result means
This calculates a company-car advisory fuel amount from miles, fuel type and the relevant engine or charging band. It uses HMRC advisory fuel rates effective 1 September 2026, not AMAP mileage rates for employee-owned vehicles.
Hybrid cars are treated as petrol or diesel for these advisory rates. Fully electric cars use separate home and public charging rates.
Worked example
A 500-mile business journey in a 1,401–2,000cc petrol company car:
- Rate
- 17p per mile
- Miles
- 500
- Advisory amount
- £85.00
The rate is a current-policy reference, not a substitute for checking the official guidance.

| Small | 14p | 15p | 11p |
| Medium | 17p | 16p | 13p |
| Large | 27p | 22p | 20p |
| Electric — home | 7p | — | — |
| Electric — public | 15p | — | — |
Source and review timing
HM Revenue & Customs publishes these advisory rates on GOV.UK. The displayed set is effective from 1 September 2026; HMRC reviews advisory rates periodically, so confirm the current official guidance before using a result.
These rates apply to employees using a company car in the appropriate circumstances. They differ from Approved Mileage Allowance Payments for employees using their own vehicle.
Select the correct scheme
Choose AFR for a company car and the matching fuel/engine band or electric charging location. Choose the HMRC Mileage Calculator for qualifying business travel in an employee-owned vehicle. A fuel price or actual vehicle cost can justify a different evidenced rate in relevant circumstances; this page does not assess that evidence.
Assumptions and limitations
- Petrol, diesel and LPG engine band labels must be matched to HMRC’s specific thresholds.
- Electric home/public charging selection reflects where charging occurs.
- Rates are subject to periodic review and eligibility rules.
