Enter the bill amount, choose a tip percentage, and split the total among diners.
A check comes to 84.60 before tax. Four people are splitting it and want to leave 18 percent.
Tip 15.23, total 99.83, 24.96 each.
Both are done and neither is wrong, but they are not the same number. Tipping on a pre-tax subtotal of 84.60 at 18 percent gives 15.23. If tax has already pushed the check to 91.80 and you tip on that, you pay 16.52 — about 1.30 more, purely because you tipped on money the restaurant never received. Decide which you mean, then enter that figure in the bill field consistently, or your tip percentage will drift depending on how heavily your area taxes restaurant meals.
It is often easier to pick the total you want and let the tip fall out of it. On an 84.60 check, paying 100 flat means a tip of 15.40, which is 18.2 percent. To do this in the calculator, try tip percentages until the total is the round number you want — or work it directly: (Target total − Bill) ÷ Bill × 100 gives the percentage. Rounding up to the nearest whole currency unit per person is the version most groups actually use, because it avoids anyone owing 24.9575.
The per-person figure here divides everything equally, which is right when everyone ate roughly the same and wrong when one person had a starter and tap water. For an itemised split, total each person’s own share of the subtotal, then apply the same tip percentage to each share — the tip stays proportional and nobody subsidises anyone else. The one thing to avoid is splitting the food evenly but the tip by item, or vice versa, which produces a total that does not match the check.
Many checks for larger parties include a service charge or gratuity line. If one is present, the tip has already been applied and entering the check total here will tip on top of a tip. Read the itemised lines before you calculate: if you see a percentage already added, either enter the subtotal before that line, or set the tip percentage to whatever extra you actually intend to add.
That is a judgement call, not an arithmetic one, and it varies by country, by venue type and by what the service charge on the check already covers. This tool does not push a number at you — it takes whatever percentage you type and does the division. The practical approach is to check the receipt for an existing service charge first, decide the percentage you are comfortable with, then use the calculator to split it accurately.
Take 10 percent by moving the decimal one place left, then build from it. On 84.60, ten percent is 8.46. Half of that is 4.23, so 15 percent is 12.69. Double the ten percent for 20 percent, which is 16.92. Anything between those two you can estimate by splitting the difference, and 18 percent lands at 15.23 — which is exactly what the calculator returns.

Because it is a true division of the total. If four people split 99.83 the exact share is 24.9575, shown as 24.96, and four payments of 24.96 come to 99.84 — a cent over. Groups usually handle this by rounding each share up to the nearest unit, which also builds in a little extra tip.
