Frequently Asked Questions

How much should I tip?

In the US, 15-20% of the pre-tax bill is standard for table service at restaurants. For exceptional service, 20-25% is common. For takeout or counter service, 10-15% is typical, though expectations vary by region.

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

Convention is to tip on the pre-tax subtotal, though many people tip on the total including tax out of convenience. Tipping on the pre-tax amount is perfectly acceptable.
