How the tip calculator works
The tip calculator helps you estimate results using the assumptions and values you provide. Review the formula and example before relying on the result.
Formula and assumptions
Tip = bill × tip rate ÷ 100. Per person = (bill + tip) ÷ number of people.
Example
An 80 bill with a 15% tip totals 92; split between two people, each pays 46.
Important information
