Milometry 1.2.0: Thai, vehicle types, motorbike rates and electric cars

Version 1.2.0 is the biggest change to Milometry since it launched, and almost all of it comes from one question that kept arriving in different forms: "my vehicle is not a petrol car, what happens to my figures?" Here is what happens now.

Thai, and Thailand

Milometry reads in Thai, its seventh language after English, French, Spanish, German, Dutch and Japanese. Every screen, the exports, the reminders, the Siri phrases and the permission prompts are in Thai, and so is this site, including the tutorials.

Thailand is the thirteenth country with a scheme built in. The figure is the Thai government's reimbursement for official travel in a private vehicle, 4 baht a kilometre for a car and 2 baht for a motorcycle, set by the Ministry of Finance in 2007. It is a benchmark, not a tax-free allowance for private employers, and the app says so in every place the figure appears. There is a separate post on what the Thai rate is and is not.

As always, language and rates are separate choices. A Thai speaker working in Britain reads Thai and claims HMRC rates.

Every vehicle has a type

A vehicle is now a car, a van, a motorbike, a scooter or a company car, and that decides how its business trips are priced:

• HMRC pays motorbikes 24p a mile with no 10,000-mile threshold, on a distance pool of their own, so a motorbike's miles never eat into the car's band. Germany publishes 20 cents for a motorbike and Austria 50 cents under the same 30,000 km ceiling as a car, and the app applies each.
• The Dutch, Belgian and Spanish allowances pay any vehicle the same per kilometre, so a scooter there is priced from the car figure.
• Where an authority publishes nothing for motorbikes (the IRS, the CRA, the ATO, Ireland, France), those trips are recorded and counted but left out of the figure, and every total says how many it left out. Nothing is silently priced at the car rate.
• A company scheme or a custom rate prices whatever you drive.

Each vehicle also has a default category for its trips, so a van used only for work files its drives as business without a swipe, and an include-in-mileage switch for a vehicle you track but do not claim.

Electric cars, charged and costed

Tell Milometry a car is electric or a plug-in hybrid and the fill-up screen becomes a charge screen: kWh, cost, where you plugged in, and the battery percentage before and after. A plug-in gets both.

Three things make this more than a renamed fill-up:

• A tariff book holds your home, off-peak, work and public rates, with the hours your off-peak window runs. A charge prices itself from the kWh, and every journey is costed at your cheapest home rate rather than the last motorway rapid charger.
• Battery readings measure your real efficiency from any two charges, no charge to 100% needed. The app says what a full battery is worth at that efficiency, and spots a charge that was never logged.
• Everything downstream follows: the live figure while you drive, each trip's cost, the calculator, Insights, the trip PDF and the CSV, and CO₂ counted at the grid's generation rate rather than as zero.

The numbers behind why this matters are in Electric cars in 2026, by the numbers, and the cost of a mile under each kind of charging is in What an electric mile actually costs.

Smaller things

• The claim PDF and the detailed CSV show each trip's vehicle type and energy.
• A year's rates you corrected by hand, the motorbike figure included, are kept apart from a template update.
• Thai, like every language, keeps its own date patterns and number formatting.

Claim figures are estimates to help you keep a record. They are not tax advice.
