How Tip Calculations Work
The tip is calculated as a percentage of the pre-tax bill amount. The four key figures are:
Tip Amount
Bill × Tip% ÷ 100
$80 × 20% = $16.00
Total Bill
Bill + Tip Amount
$80 + $16 = $96.00
Tip Per Person
Tip Amount ÷ People
$16 ÷ 4 = $4.00
Total Per Person
Total Bill ÷ People
$96 ÷ 4 = $24.00
Tipping Guide by Service Type
Standard tipping norms vary by service type and country. The table below reflects US customs — arguably the world's most tip-dependent service economy.
| Service | Typical Range | Suggested | Notes |
|---|---|---|---|
| Restaurant (sit-down) | 15 – 20% | 20% | More for exceptional service |
| Café / Coffee | 10 – 15% | 15% | Optional at counter service |
| Bar / Drinks | $1–2 per drink | 15–20% | Or $1–2 per round |
| Delivery | 10 – 15% | 15% | Min $3–5 for small orders |
| Hair / Salon | 15 – 20% | 20% | On service cost, not products |
| Taxi / Rideshare | 10 – 20% | 15% | More for help with luggage |
| Hotel porter | $1–2 per bag | $2/bag | Tip at time of service |
| Housekeeping | $2–5/night | $3/night | Leave daily, not checkout only |
Frequently Asked Questions
In the US, 15–20% is the standard range. 15% is considered acceptable, 18–20% is good, and 25%+ is exceptional. In the UK and Europe, tipping customs are lower — 10–12% is typical — and in some Asian countries tipping is uncommon or even considered rude.
Etiquette guides generally recommend tipping on the pre-tax subtotal, as the server didn't provide the government's service. In practice, the difference is small — on a $100 bill with 8% tax, tipping 20% pre-tax is $20 vs. $21.60 post-tax. Either is perfectly acceptable.
Tipping on takeout is optional but appreciated. A 10% tip is a common gesture to acknowledge the packaging and preparation work. If the restaurant is a full-service establishment where staff split tips, tipping is more important.
The calculator divides both the total tip amount and the total bill equally by the number of people. This assumes everyone ordered roughly the same amount. If orders varied significantly, consider splitting by individual order amounts instead.
The quality meter reflects how generous your tip percentage is relative to US norms: Low (under 10%), Fair (10–14%), Good (15–19%), Generous (20–24%), Exceptional (25%+). It's a quick visual cue — not a judgment — to help you decide on the right amount.
Yes — entering 0 or selecting Custom and typing 0 will show a $0 tip. The meter will show "Low". Tipping is always voluntary; the calculator makes no assumption about what you should give.
