About the Tip Calculator
Splitting a bill and calculating an appropriate tip at the table is a common source of quick mental math, especially in a group setting where people want to divide the total evenly without shortchanging the server.
This calculator handles both parts at once: it applies a chosen tip percentage to the bill total, then divides the full amount — bill plus tip — evenly across the number of people in your party.
Frequently Asked Questions
What's a standard tip percentage in the US?
15-20% is generally considered standard for sit-down restaurant service in the US, with 18-20% common for good service and 10-15% for below-average service, though norms vary by region and country.
Should I tip on the pre-tax or post-tax bill amount?
Etiquette guidance varies, but many people tip on the pre-tax subtotal. This calculator applies the tip percentage to whatever bill amount you enter.
How do I split a bill unevenly?
This calculator assumes an even split across all people. For itemized or uneven splits based on what each person ordered, you'd need to calculate individual subtotals separately first.
