Enter your car details, energy cost, journey and year-to-date (YTD) business miles. We’ll calculate your actual trip cost and your HMRC mileage allowance for a single and a return journey, applying 45p/mi up to 10,000 miles then 25p/mi after.
Disclaimer: HMRC mileage allowance rates are correct at time of writing but may change in the future. Always check the latest HMRC guidance.
For petrol/diesel, enter price per litre. For EVs, enter price per kWh. Values are editable.
We’ll automatically apply 45p/mi until you reach 10,000 mi in the tax year, then 25p/mi after that.
