How to use Bill Split & Tip Calculator

1. Prepare the required inputs

Calculate the tip and split a bill with a rounding plan that covers the total exactly. Use the units and options beside each field. Results update as inputs change; reset returns to example inputs.

Bill before tip: minimum 0, maximum 1000000000000
Tip (%): minimum 0, maximum 100
Number of people: minimum 1, maximum 100

2. Try a worked example

A 100 bill plus 15% tip shared by four people is 28.75 each.

3. Understand the calculation

Tip = bill × tip%. Total = bill + tip. Divide total cents between people and allocate any remaining cents.

4. Read the assumptions

Equal split in a currency with two decimal places. Taxes should already be included in the bill. No separate service charge is added.

5. Check and compare results

Match entered values to their labels and units. Review output labels alongside the assumptions, then change one input at a time. A currency selector changes display labels without converting amounts. Use the available save or copy actions and retain the input values so the estimate can be reproduced.

6. Fix an invalid input

Complete required fields and respect the listed bounds. Check date order, age relationships and mode-specific requirements where relevant; the error message identifies invalid combinations. Reset to example inputs to recover. A valid calculation applies to its stated model and does not verify a real-world outcome.
