Tip and Split Calculator
Working out a tip and dividing a restaurant bill should take seconds, not an argument over loose change. This calculator does both at once: you enter the bill amount, the tip percentage you want to leave, and the number of people sharing, and it returns the tip in dollars, the grand total and the amount each person owes. The math is deliberately simple and transparent. The tip is the bill multiplied by your chosen percentage, the total is the bill plus that tip, and the per-person share is the total divided evenly by the number of diners. Because tipping norms vary, the percentage is left fully editable: 15 to 20 percent is customary for table service in the United States, with 18 to 20 percent common for good service, while counter and takeout orders often take less. You can tip on the pre-tax subtotal or the post-tax total simply by typing whichever figure you prefer into the bill field. The per-person amount already includes each diner's share of the gratuity, so once everyone pays their equal portion there is nothing more to add. Every figure here is computed deterministically from your three inputs, and the worked example below reconciles exactly to the calculator.
Each person pays the bill plus tip, divided evenly: per person = bill x (1 + tip) / people. An $80.00 bill at 18% split 4 ways means a $14.40 tip, a $94.40 total, and $23.60 each.
Tip and split formula
tip = bill x t
total = bill + tip
per person = total / n
t = tip rate as a decimal
n = number of people
The tip is a straight percentage of the bill, the total adds that tip to the bill, and the per-person share splits the total equally across everyone at the table.
Worked example
Four friends share a meal with an 80 dollar bill and leave an 18 percent tip.
- Tip: 80 x 0.18 = 14.40
- Total: 80 + 14.40 = 94.40
- Each person: 94.40 / 4 = 23.60
Each person pays 23.60. These are the calculator's default inputs, so the result above matches the widget exactly.

Tip and split calculator: frequently asked questions
How do I calculate a tip and split the bill?
Multiply the bill by the tip percentage to get the tip, add it to the bill for the total, then divide the total by the number of people. For an 80 dollar bill at 18 percent split four ways, the tip is 14.40, the total is 94.40, and each person pays 23.60.
What tip percentage is standard?
In the United States, 15 to 20 percent of the pre-tax bill is customary for table service, with 18 to 20 percent common for good service. Counter service and takeout often take less or nothing. The percentage is editable so you can tip what you feel the service deserves.
Should I tip on the pre-tax or post-tax amount?
Either is acceptable, though tipping on the pre-tax subtotal is the traditional approach. Tipping on the post-tax total adds a little extra. This calculator applies the percentage to whatever bill figure you enter, so type the subtotal if you want to tip pre-tax.
How do I split unevenly between people?
This tool splits the total equally. For an uneven split, work out each person's share of the items, apply the same tip percentage to each share, then add tax proportionally. An equal split is simplest and is what most groups use for a shared meal.
Does the per-person amount include the tip?
Yes. The per-person figure is the full total, bill plus tip, divided by the number of people, so each share already covers its portion of the gratuity. There is nothing extra to add on top once everyone pays their equal share.
