Understanding restaurant tipping etiquette is one of those things everyone needs but nobody formally teaches. This guide covers everything — from the standard 20% tip to special situations like group dining, bad service, and buffets.
📊 The 2026 Restaurant Tipping Standard
The national average tip at US sit-down restaurants is now 19.4%. The expected range for good service is 18–20%, with 25% for exceptional service. Tipping below 15% is generally considered a sign of dissatisfaction.

Understanding Restaurant Tipping Etiquette
Should you tip on the pre-tax or post-tax amount?
Tipping on the pre-tax amount is technically correct since you're rewarding the service, not the government. In practice, most Americans tip on the full post-tax bill — the difference is usually under $1.50 on a $50 meal and it's not worth the mental math.
What if the service was bad?
Before reducing your tip, consider what caused the poor experience. Slow food, wrong orders, or cold dishes are usually kitchen problems — not your server's fault. If the service itself was inattentive, rude, or dismissive, tipping 10% signals your dissatisfaction while still acknowledging the work done.
Group dining and automatic gratuity
Most restaurants add 18–20% gratuity automatically for groups of 6 or more. Always check your bill before adding more. If the automatic gratuity is already there, you're done — no additional tip needed unless you want to add more for exceptional service.
The tip on alcohol debate
You should tip on your full bill including drinks. Your server carried and served your drinks too. Some diners tip on food only and tip separately per drink at the bar — either approach is acceptable.
How to Calculate a Restaurant Tip Quickly
The fastest mental math trick for a 20% tip: move the decimal point one place to the left to get 10%, then double it.
Example: $68 bill → $6.80 (10%) → $13.60 (20% tip)
For 15%: find 10%, then add half of that. $68 → $6.80 + $3.40 = $10.20
