Category Range What It Means Status
Sit-down restaurant — standard service 18% – 20% Now commonly cited as the baseline for good full-service dining post-2020, up from the older 15% convention. Calculate on the pre-tax subtotal. Good
Sit-down restaurant — excellent service ★ 20% – 25% For above-and-beyond service — attentive staff, accommodating special requests, or a especially long or complex visit. ★ Best
Sit-down restaurant — older baseline 15% The traditional US minimum, still common but increasingly viewed as the floor rather than the norm for full-service dining. Okay
Bartenders 18% – 20% of the tab Same range as restaurant service; some patrons instead tip $1–$2 per drink for simple orders at a busy bar. Good
Hair stylists / salon / spa 15% – 20% Applies to the service cost before any product purchases, which usually aren't tipped on. Good
Rideshare / taxi drivers 10% – 20% Higher end for help with luggage, a long or difficult route, or excellent communication. Okay
Food delivery ~10%, or a flat $3–$5 minimum Often lower than dine-in service since delivery apps already charge separate service and delivery fees. Okay

Worked Examples

Simple Dinner, No Tax Entered

Bill Amount
$60.00
Tax Amount
not entered
Tip Percentage
20%
Split Between
1 person
$12.00 tip, $72.00 total

$60.00 × 20% = $12.00 tip. Total = $60.00 + $12.00 = $72.00. With no tax entered, the calculator tips on the full bill amount.

Dinner With Tax Backed Out (Pre-Tax Tipping)

Bill Amount
$107.50
Tax Amount
$7.50
Tip Percentage
20%
Split Between
1 person
$20.00 tip, $127.50 total

Pre-tax subtotal = $107.50 − $7.50 = $100.00. Tip = $100.00 × 20% = $20.00. Total = $107.50 (bill, incl. tax) + $20.00 = $127.50 — about $1.50 less tip than tipping on the post-tax total would give ($107.50 × 20% = $21.50).

Group Dinner Split 4 Ways

Tax Amount
$12.00
Tip Percentage
18%
Split Between
4 people
$30.96 tip, $214.96 total, $53.74 per person

Pre-tax subtotal = $184.00 − $12.00 = $172.00. Tip = $172.00 × 18% = $30.96. Total = $184.00 + $30.96 = $214.96. Per person = $214.96 ÷ 4 = $53.74.

2 people
$11.25 tip, $56.25 total, $28.13 per person

$45.00 × 25% = $11.25 tip. Total = $45.00 + $11.25 = $56.25. Per person = $56.25 ÷ 2 = $28.125, rounded to $28.13.

Bill Amount
$32.00
Tax Amount

Split Between
1 person
$4.80 tip, $36.80 total

$32.00 × 15% = $4.80 tip. Total = $32.00 + $4.80 = $36.80. The 15% rate is the older baseline convention — many now tip 18-20% even at the bar.

What Each Value Means

Tip Amount (dollars ($))
The gratuity in dollars, calculated as the tip percentage applied to either the full bill or the pre-tax subtotal, depending on whether a tax amount was entered.
Pre-Tax Subtotal (dollars ($))
The bill amount minus sales tax — the amount tipping etiquette guides recommend basing the tip on, since tax is collected for the government rather than the service provider.
Per-Person Split (dollars ($))
The total bill (including tip) divided evenly by the number of people sharing the check.

Frequently Asked Questions

Should I tip on the pre-tax or post-tax total?
Tipping etiquette says the pre-tax subtotal is more correct, since sales tax goes to the government, not your server — tipping on the post-tax total effectively tips extra on money that never reached the person serving you. In practice, many people tip on the printed total out of convenience since it's the number right in front of them, and the dollar difference is usually small. This calculator tips on the pre-tax subtotal automatically whenever you enter a tax amount, and falls back to tipping on the full bill amount if you leave tax blank.
What percentage should I tip at a restaurant?
18% to 20% is now commonly cited as the standard for good full-service dining, up from the older 15% baseline that many people still use as a floor. For excellent service, 20% to 25% is a common range. The exact 'right' number depends on your region, the restaurant type, and your own judgment — there's no single legally or universally correct rate in the US.
How do I split a bill and tip evenly among a group?
Add the tip to the bill first, then divide that combined total by the number of people — not the bill and tip separately, which can introduce rounding mismatches. This calculator does that automatically: enter the number of people splitting the bill, and it divides (Bill + Tip) by that count to show what each person owes.
Do tipping percentages differ by service type?
Yes. Common US conventions: sit-down restaurants 18-20% (up to 25% for excellent service), bartenders 18-20% of the tab, hair stylists and spa services 15-20%, rideshare and taxi drivers 10-20%, and food delivery around 10% (often lower since delivery apps already charge separate service and delivery fees). These are common ranges, not fixed rules — always use your own judgment for the specific service you received.
Is tipping the same everywhere in the world?
No — tipping norms vary enormously by country and culture. Some countries (much of East Asia) consider tipping unnecessary or even mildly awkward, some European countries expect a small rounding-up rather than a percentage, and some places automatically add a service charge to the bill so an additional tip isn't expected. This calculator uses US dining and service conventions; if you're tipping abroad, look up the local custom before applying a US percentage.
