Three friends, one bill, and the quiet standoff over who does the maths. This page ends it in about ten seconds. Enter the bill, pick a tip percentage, and you get the tip amount, the total, and what each person pays, with or without tax.

The argument it settles

A tip is a percentage of the bill, and the total is the bill plus tax plus tip. Tip = Bill × Tip %. Tax = Bill × Tax %. Total = Bill + Tax + Tip. Each share = Total ÷ People.

The tip is usually calculated before tax, as a percentage of the pre-tax bill. After-tax tipping comes out slightly higher — see How Much to Tip for the full before-vs-after-tax comparison.

The usual picks are 15%, 18%, 20%, or 25% at a restaurant; 10%, 15%, or 20% for delivery; and splits of 2–8 people.

As a rough guide in the US, 15–20% is standard for sit-down restaurant service, 10–15% for delivery, and 10% or a flat dollar or two for counter service. These are customs, not rules. Good service earns more, poor service less, and in some countries tipping is not expected at all. The calculator also handles the split: even, by number of people, or uneven, and rounding if you want each share to land on a tidy number.

One bill, done properly

Dinner bill $86.40, tax 8%, tip 20% on the pre-tax bill, split between 3 people. Tax comes to $86.40 × 8% = $6.91. Tip is $86.40 × 20% = $17.28. Total: $86.40 + $6.91 + $17.28 = $110.59. Each share: $110.59 ÷ 3 = $36.86 per person.

Had the tip been calculated after tax instead, it would be ($86.40 + $6.91) × 20% = $18.66, about $1.38 more. That is the whole before-vs-after-tax debate in one number: small on one meal, noticeable over a year of eating out.

Tip amount is what goes to the server. Total is what the table pays altogether. Per person is the fair split. If shares come out uneven (like $36.86), rounding up to $37 each leaves a few cents extra, a tidy way to cover a rounding gap without an awkward coin hunt. For uneven splits, one person had the steak, another had a salad, work out each person’s share on their own items first, then add tip per person. And check the receipt first: some bills already include a service charge or gratuity for large groups, and tipping on top of that means paying twice. Tipping customs vary by country, city, and setting, so check local norms when travelling. The calculator does not know your local tax rate, so enter the one on your receipt.

Questions

Should I tip before or after tax?

Most people tip on the pre-tax bill, and that is the calculator’s default. Tipping after tax gives a slightly larger tip. Either is acceptable. Pick one and stay consistent.

How much should I tip at a restaurant?

In the US, 15–20% of the pre-tax bill, with 20% the common default for good service. See How Much to Tip for the full guide.

How do I split a bill fairly?

For an even split, divide the total by the number of people. For an uneven split, work out each person’s food and drink, add their share of tax and tip, and total those.

What if the bill already includes a service charge?

Then a tip is usually already covered. Check the receipt for “service charge,” “gratuity,” or “service included” before adding more.

Can I round each share up to a tidy number?

Yes. Rounding each share up to the nearest dollar or pound leaves a few cents extra, which covers the rounding gap without an awkward coin hunt.
