Baht bill split calculator

Split a total bill equally after adding any extra amount you choose. Enter the bill exactly as charged, the extra amount in baht, and the number of people sharing. The result divides the total into satang, distributing any remainder explicitly. It assumes no standard tip, tax or restaurant service-charge rate.

See the calculation.

Accept bill and extra with at most two decimal places. Convert each decimal amount to integer satang before addition. Divide total satang equally; distribute the remaining satang one each.

A worked example

1,000 baht among 3 people: one pays 333.34 and two pay 333.33 baht.

What the result leaves out

Only whole-satang amounts are accepted: at most two decimal places for bill and extra. The displayed shares add back to the entered total. Do not add taxes or service charges twice if already on the bill.
