Should I tip before or after tax?
That depends on your local custom and preference. The calculator lets you base the tip on the pre-tax subtotal, subtotal plus tax, or subtotal plus tax and service.

Tip and split formulas
Keep each line item separate so the receipt total and per-person total stay clear.
Tax
tax = subtotal x tax rate / 100Service charge
service charge = subtotal x service rate / 100Tip
tip = selected basis x tip rate / 100, or fixed tip amountBill total
total = subtotal + tax + service charge + tipSplit
per person = rounded total / peopleFAQ
What does rounding buffer mean?
When each person is rounded up or the total is rounded up, the collected total can be slightly higher than the exact bill. The buffer shows that extra amount.
