Tip Calculator

Calculators · Added 12 August 2026

Enter the bill, choose a percentage, and get the tip, the total and the amount each person owes. It also handles the two details most tip calculators skip: tipping on the pre-tax amount, and rounding the total to something you can actually hand over.

The total on the check, as printed.

Only needed if you want to tip on the pre-tax amount.

How to use the tip calculator

  1. 1Enter the bill total as printed on the check, and pick your currency.
  2. 2Choose a tip percentage from the presets, or enter your own.
  3. 3Set how many people are splitting it — leave it at one if you are paying alone.
  4. 4If you want to tip on the pre-tax amount, enter the tax shown on the bill and tick that option.
  5. 5Tick 'round the total up' to get a whole number; the tip absorbs the difference and the effective rate is shown.

Examples

A straightforward dinner

Input
84.50 bill, 18% tip, paying alone
Result
Tip 15.21 · Total 99.71

Split four ways

Input
156.00 bill, 20% tip, 4 people
Result
Tip 31.20 · Total 187.20 · 46.80 each

Tipping before tax

Input
100.00 bill including 8.00 tax, 20% tip on the pre-tax amount
Result
Tip 18.40 · Total 118.40

Tipping on the full 100 instead would add 20.00 — the gap grows with the tax rate.

About the tip calculator

The quick mental version

Ten percent is the decimal point moved one place left, and everything else builds from there. Half of that ten is five, so 15% is the two added together. Double the ten and you have 20%. On an 84.50 bill: 8.45, plus 4.23, gives about 12.70 for 15%; or 16.90 for 20%.

That approximation is close enough to leave cash on a table. This calculator exists for the cases where it is not — an awkward split, a percentage between the round numbers, or a bill large enough that a couple of currency units either way is worth a moment's arithmetic.

Splitting a bill without an argument

An even split is the fastest route and works when everyone ate roughly the same. Where it goes wrong is the table where one person had a starter and tap water and another had three courses and a bottle of wine — an even split silently moves money between them, which is fine if everyone agrees and irritating if nobody discussed it.

The middle path most groups end up at: split the tip and the tax evenly, since service and tax scale with the whole table, and assign the food and drink lines to whoever ordered them. It takes a minute longer and it is the version nobody remembers afterwards, which is the point.

Frequently asked questions

Should I tip on the amount before or after tax?
The common convention in the United States is to tip on the pre-tax subtotal, on the reasoning that sales tax is not part of the service. Tipping on the total is also widespread and nobody will object to it. On a typical bill the difference is a percent or two of the total, so the honest answer is that either is fine — this tool supports both so you can see the gap rather than guess at it.
How much is a normal tip?
It depends entirely on where you are, and no calculator should pretend otherwise. In the United States 15–20% is the usual range for table service. In much of Europe service is included and rounding up is enough. In Japan tipping can cause genuine offence. Check the local convention before assuming a percentage travels.
Why does the effective rate change when I round up?
Because rounding adjusts the total, and the tip is what absorbs the difference — the bill itself is fixed. Rounding a 99.71 total up to 100 turns an 18% tip into about 18.3%. The tool shows that recalculated rate so the rounding is never hidden from you.
Does it handle a service charge already on the bill?
Not as a separate field. If a service charge is already included, that is usually the tip — enter 0%, or a small extra percentage if you want to add to it. Read the bill carefully first: an included service charge and a blank tip line on the card machine is a common way to be tipped twice.
