How Tip Calculation Works
Tip Amount = Bill × (Tip % ÷ 100)
Total = Bill + Tip Amount
Per Person = Total ÷ Number of People
Total = Bill + Tip Amount
Per Person = Total ÷ Number of People
How Much to Tip by Service Type
| Service | Suggested Tip | Notes |
|---|---|---|
| Sit-down Restaurant | 15–20% | 20% is the norm in most US cities |
| Buffet | 10% | Someone still refills drinks and clears plates |
| Takeout / Counter Service | 0–10% | Optional; consider tipping during busy hours |
| Food Delivery | $3–5 or 15–20% | More for bad weather or long distance |
| Bar | $1–2/drink or 15–20% | $1 for beer, $2 for cocktails as a baseline |
| Coffee Shop | $0.50–1 | Not required; tip more for complex drinks |
| Hair Salon | 15–20% | Cash tips preferred by stylists |
| Rideshare / Taxi | 15–20% | Minimum $2 for short rides |
| Hotel Housekeeping | $2–5/night | Leave on the pillow with a thank-you note |
Mental Math: Quick Tip Shortcuts
- 10%: Move the decimal left one place. $85 → $8.50
- 15%: Find 10%, then add half. $8.50 + $4.25 = $12.75
- 20%: Double the 10% figure. $8.50 × 2 = $17.00
- 25%: Divide the bill by 4. $85 ÷ 4 = $21.25
Tip on Pre-Tax or Post-Tax?
Tip on the pre-tax amount. The tax goes to the government, not your server. On a $50 food bill with $4 tax and a 20% tip, the difference is only $0.80. Tipping on the post-tax total is also fine — most servers won’t notice the difference.

Special Situations
- Bad service: Tip at least 10%. Bad food is the kitchen’s fault, not your server’s. Speak to the manager instead.
- Comped meals / gift cards: Tip on the original price, not what you paid.
- Happy hour discounts: Tip on the full price — the bartender worked just as hard.
- Large groups (6+): Many restaurants auto-add 18–20% gratuity. Check your bill first.
- Movers: $20–50 per mover, or 15–20% of the total.
