Calculate a tip amount, total bill, and per-person split from a bill amount and tip percentage.
This tool calculates a tip amount as bill × tip %, the total bill including tip, and an even per-person split if you're sharing the bill -- the standard everyday restaurant tip calculation.
Enter your bill amount, tip percentage, and number of people splitting the bill. The tip amount, total, and per-person share appear instantly.
The tool multiplies the bill by the tip percentage divided by 100 to get the tip. It adds the tip to the bill for the total, then divides the total by the number of people for a per-person figure. If you enter fewer than one person, it treats the group as one person. The tip is applied to whatever bill amount you type, so the result depends on whether that amount includes tax.
Tip = bill x tip % / 100. Total = bill + tip. Per person = total / number of people.
A $50.00 bill with an 18 percent tip and one person gives a tip of $9.00 and a total of $59.00. Now try a larger group: a $86.40 bill at 20 percent shared by three people. The tip is $17.28, the total is $103.68, and each person's share is $34.56. Because the calculation is done on the whole bill and then divided, the per-person figure is the same as if each person tipped 20 percent on their own third of the bill, as long as everyone shares equally. When the total does not divide evenly, the tool shows the per-person amount rounded to two decimals, so three people paying a rounded share may be a cent above or below the exact total.
Some restaurants add a mandatory service charge or automatic gratuity for large parties, and delivery apps or bars may handle tips differently. Look at the receipt before adding a second tip on top of an included charge. The tool does not know whether a service charge is already on the bill, so it will add whatever percentage you enter. Also, tipping norms vary by service type, location and situation: a coffee counter, a taxi ride, a hair salon and a sit-down restaurant can each carry different expectations, and any figures you read online are general conventions rather than rules.
Entering the percentage as a decimal is the most frequent error; type 18, not 0.18. Another is typing the total after the tip has already been added, which results in tipping on a tip. The tool also assumes a single tip percentage for the whole bill, so it cannot handle different rates for different items. For a mix of sales tax and tip, see the Sales Tax + Tip Calculator, and for an even split focused on a group, the Tip Split Calculator covers that scenario. Nothing here is a rule about what you owe; tipping is a personal decision that you can adjust based on service quality, local custom, and your own budget.
15-20% is commonly cited for sit-down restaurant service in the US, though norms vary by service type and region -- use whatever percentage reflects the service you received and your own judgment.
It is calculated on whatever bill amount you enter. If you type the pre-tax subtotal, the tip excludes tax. If you type the total including tax, the tip includes it.
The per-person value is shown rounded to two decimals, so when the total does not divide evenly the shares can differ from the exact total by a cent.
Leave the number of people at 1. The per-person figure will then equal the total including tip.
That is your choice. Check the receipt first, since an automatic charge may already cover the gratuity, and the tool will add any tip you enter regardless.
