Method and assumptions
Enter the subtotal in one currency. Tax is added once. Choose a tip on the subtotal or subtotal plus tax; included service sets the extra tip to zero. Rounding the whole bill and rounding every share are different: the collected total and extra collected are shown separately. Country reminders provide context and do not set a tip rate.

Frequently asked questions
How is the tip and per-person amount calculated?
Enter the subtotal in one currency. Tax is added once. Choose a tip on the subtotal or subtotal plus tax; included service sets the extra tip to zero. Rounding the whole bill and rounding every share are different: the collected total and extra collected are shown separately. Country reminders provide context and do not set a tip rate.
How do I split a bill that already includes the tip?
If the entered bill already contains tax and tip, use tax 0% and tip 0% to split that final amount once. Alternatively mark service included to suppress an extra tip. Any selected rounding still changes the amount actually collected; this is an equal split, not an itemized allocation.
