How to use this calculator
Enter the bill amount, the tip percentage and the number of people sharing the total. Choose rounding only if you want to adjust the final payment. Confirm whether your bill already includes a service charge before adding another tip.
Method and interpretation
Tip amount is bill × tip rate / 100. The total is bill plus tip, and an equal split divides that total by the number of people. Splitting the total equally assumes everyone is contributing the same amount regardless of individual items ordered.
Assumptions and limits
The number of people must be a positive whole number. This estimate does not infer tax rules or whether a tip should be calculated before or after tax. Use the bill basis you intend, and remember that rounding a per-person amount can make the collected total differ from the original total.
Worked example
On a $100 bill with a 20% tip, the tip is $20 and the total is $120. An equal split among 3 people is $40 each before any rounding adjustment.
