How the tip is calculated

Formulatip = bill × tip % ÷ 100 · total = bill + tip · each = total ÷ people

Everything is worked out in whole cents rather than decimals, which is why the per-person amounts always add back up to the total. Splitting $100 three ways gives $33.34, $33.33 and $33.33 — not three payments of $33.33 that leave the table a cent short.

How to work out a tip in your head

  1. 10% — move the decimal point one place left. On $85.50 that is $8.55.
  2. 20% — double it: $17.10.
  3. 15% — 10% plus half of it: $8.55 + $4.28 = $12.83.
  4. 18% — 20% minus 10% of that: $17.10 − $1.71 = $15.39.

In many US states there is an even quicker route: sales tax is close to half a standard tip, so doubling the tax line on the receipt lands near 15–18% in a lot of places. Check it against your local rate before relying on it.

What percentage to tip

Tipping norms are cultural, not mathematical, and they change. In the United States as of 2026 the common ranges are roughly:

SituationTypical range
Sit-down restaurant, table service18–20%, more for exceptional service
Bar, per drink$1–2 a drink, or 15–20% on a tab
Food delivery15–20%, with a few dollars as a floor on small orders
Coffee shop / counter serviceOptional — the prompts start at 10% but nothing is expected
Taxi and rideshare10–15%
Hairdresser / barber15–20%

Outside North America the picture is very different. In much of Europe service is included and rounding up is plenty; in Japan and South Korea tipping can be actively unwelcome. Use the custom percentage box rather than the default when you are travelling.

Tip on the pre-tax or post-tax total?

Both are common and neither is wrong. Tipping on the pre-tax subtotal is the traditional rule and is what most etiquette guides still say; tipping on the total including tax is simpler and slightly more generous — on an 8% tax rate it adds about 1.5% to the tip on a 20% baseline.

Enter whichever figure you want to tip on in the bill box. If you want to tip on the subtotal but split the taxed total, work out the tip first, then add the tax back yourself.

Worked examples

$85.50 bill, 18% tip, split three ways

Tip $15.39, total $100.89. Split three ways: one person pays $33.63 and the other two pay $33.63 — the cents are distributed so the table pays exactly the total.

$42 bill, and you want the total to land on a round number

Choose round the total up with a 20% tip: the total becomes $51.00 and the tip adjusts to $9.00. Easier with cash, and no maths at the table.

A $23 delivery order

20% is $4.60. On small orders many people round up to $5 — the tip rounding option does it in one tap.

Common uses

  • Restaurants: the tip and the split in one go.
  • Group meals: everyone pays the same, and the cents work out.
  • Delivery and rideshare: quick percentages on small totals.
  • Travel: a custom percentage for local norms.
  • Checking a card terminal's suggestion before you tap.

Frequently asked questions

How much should I tip at a restaurant?
In the United States, 18–20% on table service is the common range in 2026, with 15% at the low end and more for exceptional service. Norms differ a lot by country — in much of Europe and Asia, service is included or tipping is not expected at all.
How do I calculate a 20% tip quickly?
Move the decimal point one place left to get 10%, then double it. On a $47.60 bill: 10% is $4.76, so 20% is $9.52.
Should I tip on the pre-tax or post-tax amount?
Traditionally the pre-tax subtotal, though tipping on the total is common and only slightly more generous. Enter whichever amount you want to tip on — the calculator uses exactly the number you give it.
How does the split handle leftover cents?
By giving the extra cents to the first payers rather than rounding everyone up. Three people splitting $100.00 pay $33.34, $33.33 and $33.33. The result flags when a split is uneven so nobody is surprised.
Can I tip a fixed amount instead of a percentage?
Not directly here, but the maths is easy: divide your intended tip by the bill and multiply by 100 to get the percentage, or use the percentage calculator to find it.
What does the rounding option do?
"Round the tip" moves the tip to the nearest whole dollar. "Round the total up" pushes the grand total to the next whole dollar and puts the difference into the tip — useful when paying cash. Neither changes the bill itself.
