About This Calculator
A tip calculatortakes the awkward mental math out of dining, ride-shares, deliveries, and any other situation where you need to leave a gratuity. Enter your bill amount, choose or type a tip percentage, and the tool above instantly shows you the tip amount, the new total, and — if you're splitting the check with friends — the exact amount each person owes.
Use it for restaurants, bars, taxis, hotel housekeeping, hairdressers, or any service where a percentage tip is customary. The presets cover the most common rates in the United States (10%, 15%, 18%, 20%, 25%), and the custom field lets you enter any percentage you want, including fractions like 17.5%.
How to calculate a tip without a calculator
The simplest mental shortcut is the 10% trick: move the decimal point of the bill one place to the left, and that's 10% of the bill. To get 20%, double it. To get 15%, take 10% and add half of it. So a $48.00 bill is $4.80 at 10%, $9.60 at 20%, and $7.20 at 15%.
For percentages in between — like 18% — calculate 20% first, then shave off a tenth. 20% of $48 is $9.60; subtract $0.96 (a tenth of $9.60) and you get roughly $8.64. The calculator above gives you the exact figure to the cent, but the trick is handy when your phone is in your pocket.
How much should you tip in the United States?
Tipping norms vary by service, but here are the current U.S. guidelines most etiquette experts and industry groups agree on:
Restaurants (sit-down): 18–20% of the pre-tax bill for standard service, 25% for exceptional service. Some establishments add an automatic gratuity for parties of 6 or more.
Bartenders: $1–$2 per drink, or 15–20% of the tab.
Food delivery: 15–20% of the order total, with a $5 minimum for small orders.
Taxis and rideshares: 15–20% of the fare, rounded up to the nearest dollar.
Hairdressers and barbers: 15–20% of the service.
Hotel housekeeping: $2–$5 per night, left daily rather than at checkout.
Coffee shops and counter service: Optional — typically $1 or rounding up to the next dollar.
Tipping on the pre-tax vs. post-tax total
Etiquette guides traditionally recommend tipping on the pre-taxsubtotal, since sales tax isn't something the server provided. In practice, many people tip on the post-tax total because it's easier and the difference is small — a few cents on a typical bill. This calculator lets you enter whatever bill amount you want, so you can choose either approach.
Splitting the bill
When dining with a group, the simplest fair split is to add the tip to the bill total and divide by the number of people. The calculator above does exactly that — type the number of people and you'll see the per-person amount including their share of the tip. If someone in the group ordered significantly more than the rest, consider an itemized split instead and only divide the tip.
Frequently Asked Questions
How do I calculate a 20% tip?
Move the decimal point of the bill one place to the left to get 10%, then double it. A $50 bill: 10% is $5.00, so 20% is $10.00. The calculator above gives you the exact figure for any bill amount instantly — just hit the 20% preset.
How much should I tip on a $100 bill?
At standard U.S. rates: 15% = $15, 18% = $18, 20% = $20, 25% = $25. Most people tip 18–20% on restaurant bills, so $18–$20 on a $100 check is the norm. Increase to 25% for exceptional service.
Is 15% still an acceptable tip in 2026?
15% used to be the standard but has shifted upward over the past decade. Today most U.S. etiquette guides treat 18% as the new baseline for adequate restaurant service, with 20% considered standard for good service. 15% is still acceptable in casual or counter-service settings but is increasingly seen as low for a sit-down meal.
Should I tip on tax or pre-tax?
Etiquette experts recommend tipping on the pre-tax subtotal because tax isn't part of the service. In practice, the difference is small (a few cents on most bills) and many people just tip on the total for convenience. Either is acceptable.
How do I split a bill with tip among multiple people?
Add the tip to the bill total, then divide by the number of people. For a $80 bill with a 20% tip ($16) split among 4 people: $96 ÷ 4 = $24 per person. The calculator above does this automatically when you enter the number of people.
Do I have to tip if a service charge is already included?
Generally no. Many restaurants in the U.S. add an automatic gratuity (typically 18%) for large parties, and some add a 'service charge' on every check. If the line item explicitly says 'gratuity' or 'service charge,' that money goes to staff and an additional tip is optional. If you're unsure, ask your server whether the service charge is the tip.
How much should I tip for delivery?
15–20% of the food total is the U.S. standard for delivery drivers, with a minimum of $5 for small orders or $7–$10 in bad weather. The 'delivery fee' charged by the restaurant or app is usually not the driver's tip — it goes to the company.
Is tipping required in the United States?
Tipping is not legally required in the U.S., but it's a deeply ingrained social norm in the service industry. In most states, tipped workers earn a sub-minimum 'tipped wage' (as low as $2.13/hour federally) and rely on tips to make a living wage. Choosing not to tip is widely considered impolite outside of explicit no-tipping establishments.
