Thank you for your help

Business have mileage rates ?

Cryptic, right? ????

Ask a question that makes sense then.

 

I believe that the politically correct term is 'kilometer-age rate'.

 

If you google "_{mileage rate for business in Thailand"} you get:

Anywhere between 5-8 baht/km seems to be the usual for private companies today, the higher end being more common

10 baht per kilometre.

I just got 19 km/l on my last tank. ????

I think the OP is possibly asking how much per kilometer you can claim (as a business expense), if using a car for business. Most countries have a predefined amount set by their tax office.

If you are asking for the actual cost it is worked out as follows

purchase price / expected total kms before disposal

plus maintenance and repairs over the expected life time

insurance and rego 

fuel cost to travel the expected life miles

 

i believe you will find the cost will be between 14-18 B per km for average everyday vehicles.
