Tip Calculator

The calculation itself is one multiplication: bill × tip rate. The judgement calls are what the bill should be, what the rate should be, and how the result divides between people. Get those three right and the arithmetic follows. In the United States the convention is to tip on the pre-tax subtotal, because tax is money that never reaches the restaurant. On a $92 subtotal with $8.05 of tax, 20% is $18.40 rather than $20.01 — a $1.61 difference per meal, and roughly $150 a year for someone eating out twice a week.

Percentages people actually use

In US full-service restaurants, 18% is the floor for adequate service, 20% is the working standard, and 25% signals genuinely excellent service or a low-value bill where the server did the same work for less money. Counter service and coffee sit around 10–15% or a rounded dollar amount. Delivery is typically 15–20% with a $5 minimum, since a short-distance driver on a small order otherwise earns almost nothing. Bartenders are conventionally tipped $1–2 per drink or 20% of the tab. Hair and beauty services run 15–20%; taxis and rideshare 10–15%; hotel housekeeping $3–5 per night, left daily because staff rotate.

Tipping outside the United States

Tipping norms are local, not universal. In Japan and South Korea tipping is not practised and can cause discomfort. In much of continental Europe service is included by law and rounding up or leaving 5–10% is generous. The UK commonly adds a 12.5% discretionary service charge that you may ask to remove. Australia and New Zealand pay full minimum wages and treat tipping as optional. In many parts of the Middle East and South Asia, 10% is standard. Before travelling, check whether service is already on the bill — paying twice is the most common tourist error.

Automatic gratuity and double-tipping

Parties of six or more are frequently charged an automatic gratuity of 18–20%, which appears as a line item rather than in the tip box. Scan the itemised bill for "service charge", "gratuity", or "auto-grat" before adding anything. Where a charge is already applied, an additional tip is entirely optional and usually reserved for exceptional service. Card terminals compound the problem by suggesting percentages calculated on the post-tax, post-service-charge total, which can push a nominal 20% suggestion to an effective 26%.

Splitting a bill without shortchanging anyone

An even split works when orders are comparable. When they are not, split by item: each person's share of the tip should be proportional to their share of the subtotal, not divided equally. Calculate each person's subtotal, apply the same tip percentage to each, then add each person's share of tax. When rounding to whole dollars, round each person up — rounding down leaves the server short. If one person pays by card and others reimburse in cash, the payer should collect the rounded amounts and adjust their own share downward to keep the total exact.

Mental shortcuts that hold up

• 20%: move the decimal one place left and double it. $46.80 → $4.68 → $9.36.
• 15%: 10% plus half of 10%. $46.80 → $4.68 + $2.34 = $7.02.
• 18%: 20% minus a tenth of that 20%.
• Tax-based estimate: in an 8% tax jurisdiction, doubling the tax line lands close to 16%.

Why the tip matters more than it looks

Under the US federal tipped minimum wage, direct employer pay can be as low as $2.13 an hour, with tips expected to close the gap to the standard minimum. Servers frequently "tip out" bussers, runners, and bartenders as a percentage of their sales rather than their tips — so an unusually low tip on a large bill can leave a server paying to serve a table. Where service genuinely fails, speaking to a manager corrects the problem more effectively than reducing the tip, which typically penalises the wrong person.
