The UK's HMRC approved mileage rate has been frozen at 45p per mile since 2011. Despite fuel, insurance, and servicing costs rising significantly. In real terms, drivers who claim mileage today are reimbursed roughly 30% less than they were a decade ago once inflation is accounted for.

Helpful tips
🔢
Set your rate before adding trips
Enter your approved mileage rate and currency at the top first. Every trip you add will calculate instantly from that rate, and changing it later will update all trips at once.
↩️
Use the Return button for round trips
Once a trip has resolved, hit the Return button to instantly add the reverse journey with addresses already filled in. Great for day trips where you drove there and back.
💾

Your trips, rate, parking entries, and settings are saved to your browser as you go. Close the tab, come back later. It'll all be waiting. It stays until you clear your browser's site data.
🅿️
Log parking with the right VAT setting
If your receipt shows a VAT-inclusive total, choose Incl. and enter your VAT rate. The calculator will extract the net claimable amount for you. If your receipt already shows the ex-VAT price, choose Excl. instead.

How travel expense calculation works
Your actual driving distance,
multiplied by your approved rate

A mileage claim reimburses you for using your own vehicle for work. The principle is simple: the distance you drive is multiplied by a rate per kilometre or mile set by your employer or tax authority. That rate is meant to cover fuel, wear and tear, insurance, and depreciation. Not just petrol.

Distances are calculated using real road routing, not straight-line estimates. This matters more than people expect: a journey that looks like 30 km on a map can easily be 40 km by road, and you are entitled to claim the actual driven distance. Always use a route-based calculator rather than estimating from a map.

Where parking is involved, the net cost. After removing any VAT, is typically claimable on top of the mileage amount. Keep your receipts, note the VAT rate shown, and record whether the amount on the receipt is inclusive or exclusive of VAT. This calculator handles that arithmetic for you.

Mileage claim = distance × rate per unit
Parking net = gross ÷ (1 + VAT%/100)
Total total = mileage + parking net
Unit miles = km × 0.621371

travel expense claims

It depends on your country and employer. In the Netherlands the standard rate for 2024 is €0.23 per kilometre. In the UK, HMRC allows 45p per mile for the first 10,000 miles and 25p beyond that. In the US, the IRS standard mileage rate is set annually. Your employer may have their own rate; use whichever is specified in your expense policy, as long as it doesn't exceed the tax authority's approved limit.

This calculator uses OpenStreetMap data and the OSRM routing engine, which may calculate a slightly different route than Google Maps. Both are using real roads, but routing engines weigh factors like road type, turn restrictions, and speed differently. Small variations of a few percent are normal. If there is a significant discrepancy, double-check that the addresses resolved to the correct locations, as partial or ambiguous addresses can occasionally be misinterpreted.

If your employer is VAT-registered, they can reclaim the VAT element of a parking receipt, meaning you should only claim the net (excl. VAT) amount from your employer. This calculator strips VAT from your parking total automatically. Always keep your original receipts, as VAT reclaims require the receipt to show the supplier's VAT number. Note that some parking operators, particularly on-street parking and councils, do not charge VAT at all.

Mileage rates are generally treated as VAT-exclusive by nature, reimbursing a fixed amount per distance unit without a VAT component being separately identified. In some jurisdictions (notably the UK), HMRC provides an advisory fuel rate that can be used to calculate the VAT element of a mileage claim, but this only applies when the employer is reclaiming VAT on the fuel portion. For most standard expense claims, the rate you enter is what you get; no VAT adjustment needed on the mileage itself.

Yes. If you drove there and back, both legs are claimable. Use the Return button on any trip card to instantly add the reverse journey with addresses pre-filled. The outbound and return distances may differ slightly if the routing engine finds a different optimal route in each direction, which is normal and fine to submit.

Generally, any trip made wholly and exclusively for business purposes is claimable: visiting a client, attending a meeting at another office, travelling to a training event, or making a delivery. The regular commute between your home and your permanent workplace is not claimable in most countries, as it is considered a personal expense. If you travel from home directly to a temporary work location, that may be claimable in full; check your employer's policy and local tax rules to be sure.
