Calculator guide
Split a bill including tip among your group. Use the explicitly labelled inputs below; rates, dimensions, and costs are assumptions, not live quotes.
Formula or method
Tip = bill × tip percent ÷ 100. Total = bill + tip; per-person amount = total ÷ party size.
How to use this calculator
- Set Bill Amount. The interface starts with 85; replace it with the value for your scenario.
- Set Tip Percent (%). The interface starts with 20; replace it with the value for your scenario.
- Set Party Size (people). The interface starts with 2; replace it with the value for your scenario.
- Compare the result with the worked example, then vary one assumption at a time so you can see what changes.
Worked example
Enter Bill Amount = 85; Tip Percent = 20 %; Party Size = 2 people. With those assumptions, the calculator gives Tip Amount: $17.00; Total Bill: $102.00; Per Person: $51.00. These outputs are calculated from the same implementation as the interactive tool.
Understanding the result
In this example, Tip Amount is $17.00. Total Bill is $102.00. Real-world schedules, fees, and local rules may differ from the assumptions entered in the tool.
Limitations and assumptions
- Real-world schedules, fees, and local rules may differ from the assumptions entered in the tool.
- The worked example demonstrates the stated assumptions, not a recommendation about your personal circumstances.
