Tip calculator quick answer
A tip calculator answers three practical questions: how much to tip, what the total bill becomes after tax and tip, and how much each person pays when the bill is split.
tip = tip base * tip percent / 100
Tip formula
tip = bill amount * tip percentage / 100
If the pre-tax bill is $50 and the tip is 20%:
tip = 50 * 20 / 100 = \$10
Pre-tax vs post-tax tipping
Some people calculate the tip on the food and drink subtotal before tax. Others calculate it on the post-tax receipt total, especially when a payment terminal presents suggested tips after tax. This calculator lets you choose either basis.
Splitting the bill
The per-person amount is:
per person = total bill / number of people
For equal splitting, include subtotal, tax, and tip in the total before dividing.
