How Much Should You Tip?

Tipping norms vary significantly by country, service type, and context. In the United States, 15-20% is standard for sit-down restaurant service, with 20% becoming the new baseline for good service. Bartenders typically receive $1-2 per drink or 15-20% of the tab. For delivery drivers, $3-5 minimum or 10-15% of the order — more for bad weather or large orders. Counter-service and fast-casual restaurants traditionally do not require tips, though it is increasingly appreciated.

The right tip reflects both service quality and your acknowledgment that tipped workers in many countries rely on gratuities as a significant portion of their income. In the US, servers typically earn a tipped minimum wage below the standard minimum wage. In contrast, tipping is uncommon or even considered rude in Japan, South Korea, and parts of Europe where service charges are included in prices. When traveling internationally, research local customs before assuming your home country's norms apply.

Frequently Asked Questions

Should I tip on the pre-tax or post-tax total?
Tipping on the pre-tax amount is technically correct, but the difference is small (a few cents to a dollar on most bills). Most people tip on the total for simplicity — either approach is acceptable.
How do I calculate 20% tip quickly in my head?
Move the decimal point one place left (divide by 10) to get 10%, then double it for 20%. For a $45 bill: $4.50 × 2 = $9.00 tip.
Is it ever acceptable not to tip?
In tipping cultures, genuinely poor service may warrant 10% or less as feedback. However, remember that kitchen issues, slow service due to understaffing, or long waits are often outside the server's control. Reserve very low or no tips for genuinely rude or negligent service.
