How to Calculate Tips and Split Bills
Enter the total bill amount, select or type your desired tip percentage (common options like 15%, 18%, 20%, and 25% are available as quick buttons), and enter the number of people splitting the bill. The calculator instantly shows the tip amount, total bill including tip, and the per-person share — all updating in real time as you adjust any value.
The tip calculator handles common dining scenarios: a solo dinner with a standard tip, a group meal split evenly, or a custom tip percentage for exceptional (or poor) service. You can adjust the tip percentage freely — there is no minimum or maximum. The per-person amount is calculated by dividing the total (bill + tip) by the number of people, rounded to the nearest cent.

Frequently Asked Questions
How much should I tip at a restaurant?
In the United States, the standard tip for sit-down restaurant service is 15–20% of the pre-tax bill. For exceptional service, 20–25% is common. For takeout or counter service, 10–15% is typical. Buffet service usually warrants 10%. Bartenders customarily receive $1–2 per drink or 15–20% of the bar tab. Tipping norms vary significantly by country — in Japan tipping is considered rude, while in many European countries a service charge is included in the bill.
How do I split a bill evenly among a group?
Add the tip to the total bill, then divide by the number of people. For example, a $120 bill with an 18% tip: tip = $120 x 0.18 = $21.60, total = $141.60, divided by 4 people = $35.40 each. This calculator handles the math automatically — just enter the bill, tip percentage, and number of people. For more complex splits where people ordered different amounts, calculate each person's share of the subtotal first, then apply the tip percentage to each individual share.
Should I tip on the pre-tax or post-tax amount?
Etiquette experts generally recommend tipping on the pre-tax subtotal, since the tax goes to the government and is not part of the service you received. However, many people tip on the post-tax total for simplicity, and the difference is usually small. On a $100 meal with 8% tax, tipping 20% on the pre-tax amount ($20.00) versus the post-tax amount ($21.60) differs by only $1.60. Either approach is acceptable.
How do I tip for a large group?
Many restaurants automatically add a gratuity of 18–20% for parties of 6 or more — check your bill before adding an additional tip. If no automatic gratuity is included, 18–20% is standard for large groups, reflecting the extra effort required to serve a bigger table. Some people recommend tipping slightly higher for large parties because service complexity increases non-linearly with group size.
Is my bill data private?
Yes. All calculations are performed in your browser using JavaScript. No bill amounts, tip percentages, or group sizes are ever sent to a server or stored anywhere. You can verify this by checking your browser's DevTools Network tab — no requests are made while using the calculator. Closing the tab erases all inputs.
