Calculate tip amount, total bill, and split the check between multiple people instantly.
Tipping customs vary by country and service type. In the United States, tipping is expected for most services: 15–20% for restaurant service, 15–18% for taxi/rideshare, $1–2 per drink for bartenders, 15–20% for hair/beauty services, and $2–5 per night for hotel housekeeping.
To calculate a tip mentally: for 20%, simply divide the bill by 5. For 15%, divide by 10 (giving you 10%), then add half of that. For a $60 bill: 20% = $12; 15% = $6 + $3 = $9. To split the check evenly between people, divide the total (bill + tip) by the number of people.
In most countries outside the US (Japan, most of Europe, China, Australia), tipping is not expected or is uncommon. In some places a service charge is already included in the bill — always check before tipping.
A tip is a percentage of the pre-tax bill. Multiply the bill by the tip rate, then divide the total by the number of people to split evenly.
On an $84 dinner for four with an 18% tip: tip = 84 × 0.18 = $15.12, total = $99.12, or $24.78 per person.
In the United States, 15–20% is standard at sit-down restaurants, 10–15% for delivery, and $1–2 per drink at bars. Many other countries tip far less or include service in the bill — in Japan tipping is not customary at all, while much of Europe rounds up or adds 5–10% when service isn't included.
Tip on pre-tax or post-tax? Convention is pre-tax, though tipping on the post-tax total is a common and slightly more generous shortcut.
Counter service? Optional — round up or leave 10% for good service.
