Work out the tip, the total and exactly what each person owes when the bill is split — with preset tip rates, custom percentages and cent-exact rounding. Runs entirely in your browser — your numbers never leave this device.
Money is rounded half-up to whole cents. Each per-person figure is rounded separately, so per-person × people can differ from the total by a cent or two — settle the odd cent in the group chat, not at the table.
Enter the bill, choose a tip — the presets cover the rates people actually use, 10, 15, 18, 20 and 25 percent, and the field accepts any custom percentage — and say how many people are splitting. The tip is the bill times the percentage, the total is the bill plus the tip, and each person's share is the total divided by the party size. The worked example below is the shape of the answer: a bill of $84.50 at 18% gives a $15.21 tip and a $99.71 total, which splits three ways at $33.24 a head.
Rounding is where bill splitters quietly disagree, so this one states its rule: every money value is rounded half-up to whole cents. The tip is rounded first, the total is the bill plus that rounded tip, and each per-person figure is rounded separately. That last step is why per-person times people can land a cent or two away from the total — a $4.75 tip split between two is $2.375 each, which rounds to $2.38, and two lots of $2.38 make $4.76. Somebody covers the odd cent; the calculator's job is to make the size of the odd cent visible rather than hide it inside a vague total.
What counts as 'the bill' is your call and worth a second's thought before you type it. Tipping on the pre-tax subtotal is the traditional convention in much of the United States; tipping on the full amount including tax is simpler and a little more generous. Likewise, if a discount or a voucher reduced the bill, many people tip on the original amount, since the server did the same work — the Discount Calculator linked below works out what a percentage off actually saved, if you want that figure before deciding. This calculator does the arithmetic at the rate you give it; choosing the rate stays a social decision, not a mathematical one.
In the United States, 15–20% of the bill is the conventional range for table service, with 18% and 20% the most common choices — the presets on this page are 10, 15, 18, 20 and 25%. Customs differ sharply by country: in much of Europe a service charge is already included and rounding up is enough, and in Japan tipping is not customary at all. The calculator accepts any percentage, including 0, because the right rate is set by where and what the meal was.
The traditional convention is on the pre-tax subtotal, because the tax is not part of the service you received. In practice many people tip on the full total for simplicity — on a typical tax rate the difference is a percent or two of the bill. Use whichever your group is comfortable with; enter that amount as the bill here and the split follows from it.
Because each per-person figure is rounded half-up to whole cents separately. The classic case is in the worked examples: a $4.75 tip split two ways is $2.375 each, which rounds to $2.38, and 2 × $2.38 is $4.76 — one cent over. Real groups settle the odd cent informally; what matters is that the rounding rule is stated, so the difference is explained rather than looking like an error.
This calculator splits evenly, which is the right tool for shared meals and the wrong one for a table where one person had a salad and another had the steak and wine. For uneven splits, each person can run their own subtotal through the same tip percentage separately — the arithmetic per person is identical, only the bill figure changes.
Yes — enter 0% if a service charge or auto-gratuity is already on the bill and you are not adding to it, and the tool becomes a pure bill splitter. If you want to add something on top of an included 18%, enter the included charge as part of the bill and set the tip field to just the extra percentage you intend to add.
