Tip

In the US, 15-20% is standard for sit-down restaurants, with 20%+ for great service. Per-person = (bill + tip) ÷ number of people.

Tipping Norms & Splitting the Bill

Tipping customs vary a lot by country, and even within the US by service type. In the US, sit-down restaurants generally expect 15-20% of the pre-tax total, while counter service, delivery, and bars often use different norms.

Per-person amount = (bill + tip) ÷ number of people

Tipping around the world

Outside the US, tipping norms shift dramatically — in Japan, tipping is often considered unnecessary or even mildly awkward, since excellent service is viewed as a standard expectation rather than something extra to reward. In much of Europe, a service charge is frequently built into the bill already, so an additional 5-10% rounding-up tip is polite but far smaller than the American norm. Always worth a quick check of local custom before assuming the percentage you're used to at home applies.

FAQ

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

Tip on the pre-tax subtotal. Tipping on the post-tax amount rounds up slightly, which is fine too, but pre-tax is the technically correct baseline most etiquette guides recommend.

Is tipping mandatory in the US?

Tipping isn't legally required, but it's a strong social expectation for sit-down service, since many servers are paid a lower base wage that assumes tip income. Skipping it entirely is generally considered rude unless service was genuinely bad.

What if the bill already includes a service charge?

Some restaurants (especially for large groups) add an automatic gratuity or service charge, usually 18-20%. Check the bill carefully — if it's already there, an additional tip isn't expected, though you can add a little more for exceptional service.

Tipping context matters

Customs differ by country and by whether service charge is already included. Confirm the bill before adding a percentage. For group meals, calculate a base split, then adjust for people who ordered differently.

Separate the tip, total bill and per-person amount

Enter the bill amount and tip rate to calculate the tip and the total including the tip. If the bill is being shared, the resulting total can then be divided among diners. Check whether a service charge has already been included so that you do not count the same charge twice.

Common mistakes and interpretation

For a $150 bill with a 10% tip, the tip is $15 and the total is $165. Split four ways, that is $41.25 per person before any rounding. Real-world payment can follow the restaurant’s rules and your preferred rounding method.

Practical use

Tipping customs vary widely by country and venue. The calculator handles the arithmetic; whether a tip is expected and what rate is appropriate should be based on local practice and the bill itself.
