Tip Calculator: Split the Bill & Tip
No more awkward phone math at the table. Enter the bill, pick a tip percentage and tell it how many people are splitting — this free calculator shows the tip, the total, and exactly what each person owes, including a rounded-up total if you like easy numbers.

How to Use This Calculator
Enter the bill amount before sales tax — that's the subtotal the tip is conventionally based on. Choose a tip percentage: 15% is the floor for decent service, 18% to 20% is the modern standard in the U.S., and 25% is for standout service.
Enter how many people are sharing the bill, then click Calculate. You'll see the tip amount, the total bill, and each person's share — plus a rounded-up version of the total if the group prefers clean numbers.
Splitting with people who ordered differently? Calculate each person's share from what they ordered instead of splitting evenly, then add their portion of the tip. Click Reset to start over.
The Formula
The math is simple: Tip = bill × tip percentage, Total = bill + tip, and Share per person = total ÷ number of people. The rounded total is the exact total rounded up to the next whole dollar.
Worked example: an $86 bill at 20% with 3 people. The tip is $86 × 0.20 = $17.20, the total is $86 + $17.20 = $103.20, and each person owes $103.20 ÷ 3 = $34.40. Rounded up, the total is $104 — $34.67 per person if you prefer equal whole dollars.
Tips
For the mental-math version: 10% is the bill with the decimal moved one place left, so 20% is double that. On the $86 example, 10% is $8.60, and 20% is $17.20 — five seconds, no calculator needed.
Remember that in the U.S., restaurant staff often earn below minimum wage and depend on tips, so rounding up rather than down is the kind move — and always check the receipt for an automatic gratuity before tipping on top of one.
Frequently Asked Questions
How much should I tip at a restaurant?
In the United States, 15% to 20% of the pre-tax bill is the standard range for table service, with 20% widely considered the norm for good service. For large parties, many restaurants automatically add an 18% gratuity, so check the bill before adding your own.
Should I tip on the pre-tax or post-tax amount?
Tipping on the pre-tax subtotal is standard — sales tax is not part of the service you received. Tipping on the post-tax total overpays by the tax rate, which is why this calculator asks for the bill amount before tax. If the service was outstanding, tip on the total as a bonus.
How do I split a bill with friends?
Add the tip to the bill first, then divide the total by the number of people. Splitting the pre-tip bill and then tipping separately usually shortchanges the server. If one person ordered significantly more, you can split proportionally to what each person ordered instead of evenly.
What is the quickest way to calculate a tip in my head?
Move the decimal point one place left to get 10%, then double it for 20%. For 15%, take 10% and add half of that. On a $46 bill: 10% is $4.60, so 20% is $9.20 and 15% is $6.90. For the dollar amount, this trick beats any calculator.
Do tipping customs differ in other countries?
Yes, significantly. In Japan, tipping can be considered rude; in much of Europe, a service charge is included and tips are just small round-ups; in Canada and the U.S., 15% to 20% is expected because staff rely on tips for most of their income. Always check the local custom before you travel.
