Start with the bill amount before tip. Multiply by the tip percentage to get the tip amount. Add that back to the bill, then divide by the number of people splitting the check.
Work the numbers in the right order
If the bill is $100 and the tip is 20%, then the tip is $20 and the full total is $120. If four people split evenly, each person pays $30.
Quick example
Bill × tip rate = tip amount. Bill + tip amount = total. Total ÷ people = per-person share.
When the split is not perfectly even
Some groups split evenly for simplicity. Others adjust for drinks, appetizers, or larger entrees. The calculator is best for the fast equal-split version, which is often the least stressful option in the moment.

Plug in the bill, tip rate, and group size when you want the total and per-person amount in one step.
