How U.S. restaurant tipping works
In the United States, restaurant servers, bartenders, hotel staff, taxi drivers, and delivery workers earn a significant share — often the majority — of their income from tips. Under the Fair Labor Standards Act, employers can pay tipped workers as little as $2.13 per hour federally (many states set higher tipped minimum wages), as long as tips bring total compensation up to the regular minimum wage. That legal structure is why a 15%–20% tip is considered standard rather than optional.
The math is trivial — the etiquette is not
The formula: Tip = Bill × Rate. Total: Total = Bill × (1 + Rate). Per person: Total ÷ People. What varies is the base you tip on — subtotal or total-with-tax — and how much rounding you do. Convention is to tip on the pre-tax subtotal, but in practice most diners tip on the whole check to avoid the mental math. On an 8% sales tax bill the difference is under half a percent.
Worked example
Four diners split an $84.60 restaurant bill and want to leave 20%. Tip = $84.60 × 0.20 = $16.92. Total = $101.52. Per person = 101.52 ÷ 4 = $25.38. Rounding up to $26 per person adds a small buffer for the server and keeps everyone's math simple.
What's expected in the U.S. today
| Service | Standard | Great service | Notes |
|---|---|---|---|
| Sit-down restaurant | 18%–20% | 22%–25% | On subtotal; more for large parties |
| Counter service / coffee shop | 0%–15% | 15%–20% | Tip if seated or personal service |
| Food delivery | 10%–20% | 20%–25% | Minimum $2–$5, more for bad weather |
| Taxi / rideshare | 10%–15% | 15%–20% | Round up for short rides |
| Bartender | $1–$2 per drink or 15%–20% | 20%+ | Higher for complex cocktails |
| Hotel housekeeping | $3–$5 per night | $5–$10 | Left daily, not at checkout |
| Hair salon / spa | 15%–20% | 20%+ | Tip the person who did the work |
Automatic gratuity and 'service charge'
Restaurants often add an automatic 18%–20% gratuity for groups of six or more — check the itemized bill. When it's already applied, an additional tip is only for exceptional service. Newer 'service charge' or 'kitchen fee' line items are trickier: they may or may not go to the staff. The IRS distinguishes tips from service charges for tax purposes, and if the charge isn't distributed to staff it's essentially a menu-price increase in disguise. Tip on top if the check says 'service charge' but the server confirms it doesn't reach them.
Tipping outside the United States
- Europe: 5%–10% is generous in most countries — servers are paid a full wage. France, Italy, and Spain often include 'service compris'; check the bill.
- UK & Ireland: 10%–12.5% is common; discretionary and often already added as a 'service charge'.
- Japan: no tipping; leaving change can be considered rude.
- China & most of Southeast Asia: not customary in local restaurants; 5%–10% at high-end / tourist venues.
- Middle East: 10%–15% is expected in restaurants; small tips for hotel and taxi staff.
Quick mental math tricks
- 10% is one decimal shift left. $84.60 → $8.46.
- 20% is 10% doubled. $8.46 × 2 = $16.92.
- 15% is 10% + half of 10%. $8.46 + $4.23 = $12.69.
- 18% is 20% minus 10% of the 20%. $16.92 − $1.69 = $15.23.
- To split evenly, divide before rounding — rounding first and dividing usually shortchanges the server.
