Frequently Asked Questions

How much should I tip at a restaurant?+

In the United States, fifteen to twenty percent is standard for sit-down service, with eighteen percent a safe middle ground. Exceptional service deserves twenty-five percent or more. Use the slider to find the figure that feels right.

Can I split the bill between multiple people?+

Yes. Set the number of diners and the calculator divides the total, including tip, evenly across everyone. The per-person figure updates instantly as you adjust tip or bill amount.

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

Etiquette experts say tipping on the pre-tax subtotal is acceptable, but most diners simply tip on the final printed total for simplicity. Either is socially appropriate.

Do tipping customs change by country?+

Yes, dramatically. Tipping is not expected in Japan and can be considered rude. Most of Europe includes a service charge and treats tips as a small thank-you. Australia rarely tips. The United States and Canada are the heaviest tipping cultures.

How do I calculate tip without the app?+

For ten percent, shift the decimal one place left. For twenty percent, do that and double it. For fifteen percent, take ten percent and add half. These shortcuts work for any bill in under a second.
