Tip Calculator & Bill Splitter

Enter the bill and a tip percentage to see the tip and total, then split it across any number of people to get the amount each person owes.

How to use

  1. Enter the bill amount.
  2. Pick a tip percentage and the number of people splitting it.
  3. See the tip, total, and the amount each person owes.

Tipping norms vary sharply. In the US and Canada service is not built into wages, so 15–20% is effectively expected. Japan and Korea do not tip at all, and most of Europe already includes a service charge — rounding up is enough.

In depth

In the US, tipping is wage structure rather than generosity

Federal law permits a "tip credit": an employer may pay tipped staff a cash wage below the minimum and count tips toward the difference.

The federal minimum cash wage is $2.13 an hour. If tips don't bring earnings up to the minimum the employer must make up the shortfall, but that reconciliation happens on a weekly average — so in practice each shift's tips are that person's income.

States differ. California, Washington and Oregon among others allow no tip credit at all and must pay the full state minimum regardless of tips. Tipping persists there, but not as the mechanism that makes the wage legal.

Withholding a tip in the US is therefore closer to docking someone's pay than to rating the service. It is a difference in labour law, not in manners.

Three broad regimes around the world

Where tips are part of the wage — the US and Canada. Restaurants 15–20%, bars $1–2 per drink, taxis 10–15%, hotel porters $1–2 per bag.

Where service is already included — most of Europe. A bill marked servizio incluso or service compris has it built in; 5–10% or rounding up covers genuine satisfaction.

Where tipping isn't done — Korea, Japan, China. In Japan, money left behind is treated as forgotten and staff may chase you down the street to return it. Insisting reads as an imposition.

When unsure, read the bill. If a service charge, gratuity or coperto already appears as a line item, anything further is optional.

Pre-tax or post-tax barely matters

Convention is to tip on the pre-tax subtotal, since the tax is not the restaurant's money.

The gap is small either way. On a $100 meal in New York City at 8.875% sales tax, an 18% tip is $18.00 pre-tax and $19.60 post-tax — a difference of $1.60.

The suggested-tip table printed on many receipts is calculated on the post-tax total. Following it means tipping slightly above convention.

Where splitting a bill goes wrong

Even split versus by-consumption: even is easier arithmetic but penalises whoever didn't drink. Agreeing before the bill arrives avoids the awkward part.

Rounding direction matters. Rounding each person's share down leaves the total short — this calculator gives the per-person figure, so either someone absorbs the remainder or everyone rounds up.

Splitting across cards works in most US restaurants, but the tip goes on each card separately. Dividing the total tip by the number of cards and writing that on each one comes out right.

Large parties often trigger an automatic gratuity of around 18% for six or more. Missing that line and tipping again means paying twice.

Beyond restaurants

Counter service at a café is not obligatory. A tablet offering 15/20/25% can be answered with "No tip" — the practice of prompting everywhere is why people talk about "tipflation".

Delivery: 15–20% of the order or a $3–5 minimum, more in bad weather or over a long distance.

Hairdressers and barbers: 15–20%. Hotel housekeeping: $2–5 left daily rather than at the end, because the person cleaning changes day to day.

Tour guides: roughly $5–10 for a half day, $10–20 for a full day.

FAQ

How much should I tip?

It varies by country and setting, but US restaurants are typically 15–20%. Quick-select buttons and a custom field are both supported.

Can it split the bill?

Yes. Set the number of people and it divides the total and tip to show the per-person amount.

Should I tip on the pre-tax or post-tax amount?

Convention usually favors tipping on the pre-tax subtotal, but many people simply tip on the total for convenience — either way, this tool lets you enter whichever amount you prefer.

Method and sources

What this tool bases its numbers on, and how far those numbers go.

What this tool is
A reference calculator. Tipping norms vary by country, sector and situation, so it does not prescribe an amount.
Formula
Tip = base amount × tip rate. Total = base + tip. Per person = total ÷ number of people. Whether the base is pre-tax or post-tax is set by the amount you enter.
Worked example
A $100 pre-tax bill at 18% gives a $18 tip and a $118 total; split four ways, $29.50 each.
Limitations
  • It does not infer a recommended rate from your country — you choose the percentage.
  • It cannot detect a service charge or automatic gratuity already on the bill. Check the receipt for parties of six or more.
  • Whether the calculation is pre-tax or post-tax depends on the figure you enter.
  • Per-person amounts are a division and may leave a remainder — round up if the total has to match exactly.
