Tip Calculator
Calculate tip, tax, and total for a bill, then split evenly across the group. Pre-tax or post-tax tipping, custom percentages, and per-person totals.
How to Use
- Enter the pre-tax bill total in dollars.
- Enter the tip percentage. The U.S. customary range is 15–25% for sit-down restaurants.
- Optionally enter sales tax — the calculator can apply your tip to the pre-tax or post-tax amount.
- Enter the number of people splitting the bill. The calculator divides the final total evenly.
- Read the tip amount, total bill, and per-person share.
- Use one of the quick-tip presets (15%, 18%, 20%, 25%) for the standard ranges.

A Brief History of the Tip
The word "tip" most likely comes from the late 17th-century English noun for a small gift, possibly via thieves' cant. By the 18th century, English coffeehouses had brass urns marked "TIPS" — "To Insure Prompt Service" is folk etymology, not the actual origin — and the practice of small payments to servers was well established in Europe long before it crossed the Atlantic. American tipping took hold after the Civil War, when wealthy Americans returning from European travel imported the custom. It was initially controversial: a serious anti-tipping movement in the late 19th and early 20th centuries argued that the practice was undemocratic and incompatible with the dignity of the American worker. Six states briefly banned tipping outright between 1909 and 1916.
The defining moment for the U.S. came in 1966, when Congress amended the Fair Labor Standards Act to allow employers to pay tipped workers a sub-minimum cash wage, with tips making up the difference to the federal minimum wage. The federal tipped minimum has been frozen at $2.13/hour since 1991. Many states set higher tipped minimums, and seven states (California, Oregon, Washington, Nevada, Montana, Alaska, Minnesota) require the full standard minimum wage regardless of tips. This wage structure is the structural reason U.S. tipping percentages have crept upward decade by decade.
The mid-2010s saw a rapid expansion of "tip creep" — point-of-sale screens at counter service, takeout, and self-checkout asking for tips on transactions where tipping was historically uncommon. Customers report increasing fatigue with the practice, and several restaurants have experimented with no-tipping policies (rolling service charges or higher menu prices into the worker's wage). The math at the bottom of the page is the same regardless of which model you prefer.
About This Calculator
This calculator handles the standard restaurant-bill math: bill amount, optional sales tax, tip percentage applied to the pre-tax base, total computed, and divided across N people. If you'd rather tip on the post-tax amount (matching what most card-reader screens do), set the tax rate to 0 and increase the bill amount to include tax — the math comes out the same.
Quick presets cover the standard U.S. ranges: 15% (passable service), 18% (standard), 20% (good), and 25% (excellent or large-party gratuity). Outside the U.S., adjust to local custom. Everything runs entirely in your browser; no bill or location information is transmitted or stored.
Frequently Asked Questions
Should I tip on the pre-tax or post-tax amount?
Pre-tax is the etiquette-book convention — your server didn't earn the sales tax. Post-tax is what most card readers and tip-suggestion screens use. The dollar difference is small (a few cents to a couple dollars) and either way is socially acceptable. Pick whichever you can do quickly without the calculator if you're in a hurry.
How much should I tip in the U.S.?
Sit-down restaurants: 15–20% (20%+ for excellent service or large parties). Bars: $1–2 per drink or 15–20% of the tab. Delivery drivers: 10–15% or $3–5 minimum. Coffee shops and counter service: tipping is optional but appreciated; a dollar or rounding up is fine. Hotel housekeeping: $2–5 per night, left daily. Hairstylists and barbers: 15–20%. Tipped workers in many U.S. states earn a sub-minimum wage that depends on tips bringing them up to the standard minimum.
How does tipping work outside the U.S.?
It varies enormously. Western Europe: 5–10% is generous (often included as service charge). Japan: tipping is generally not expected and can even be considered rude. Mexico, Caribbean: 10–15% is typical at restaurants catering to tourists. Australia, New Zealand: tipping is not expected but is welcomed for great service. Always check local custom; the U.S. is at the high end globally.
What about automatic gratuity for large parties?
Restaurants commonly add an automatic 18–20% gratuity for parties of 6, 8, or more. By IRS rules these auto-gratuities are treated as service charges (wages), not tips, with different tax handling for the restaurant. Read the bottom of your check carefully — adding a separate tip on top of an auto-gratuity is a common mistake.
Should I tip on the bottle of wine?
Etiquette is mixed. Some tip the full percentage including wine; others tip the standard percentage on food only and a smaller flat amount per bottle (e.g., $5 per bottle). Top sommeliers at high-end restaurants typically expect the full percentage on wine; casual restaurants are more relaxed.
Is the suggested tip on the receipt accurate?
Often it includes the sales tax in the basis (post-tax tip), and sometimes it's calculated against the total including delivery fees, service fees, or auto-gratuity that already went to the staff. Always check the math. Tipping screens at counter service have steadily expanded to include businesses where U.S. tipping was traditionally rare; you're not obligated to use the on-screen suggestions.
