How to Calculate a Tip
Calculating a tip is straightforward: multiply the bill amount by the tip percentage expressed as a decimal. For example, a 20% tip on a $75 bill is $75 x 0.20 = $15. The total bill would be $75 + $15 = $90. If splitting among three people, each person pays $90 / 3 = $30.
Standard Tipping Guidelines in the United States
Restaurants (sit-down): 15% to 20% is standard, with 18% being a common default. Tip 20% or more for exceptional service. For large parties, many restaurants automatically add an 18% to 20% gratuity.
Delivery and takeout: 10% to 15% for delivery, with a minimum of $3 to $5. Takeout tipping has become more common at 10% to 15%.
Coffee and counter service: $1 to $2 per drink, or 15% to 20% for specialty drinks. For standard drip coffee, a dollar or two is customary.
Bars: $1 to $2 per drink, or 15% to 20% of the total tab for mixed drinks and cocktails.
Hair and personal services: 15% to 20% is standard for haircuts, styling, massage, and spa services.
When to Tip More or Less
Consider tipping above 20% for large groups, complex orders, special requests, or when the service was truly outstanding. Holidays are also a time when tipping above standard rates is appreciated. If service was poor, 10% to 15% is generally appropriate, and you may want to speak with a manager about the issue rather than leaving no tip at all.
Tipping on Pre-Tax vs. Post-Tax Amount
Etiquette guides generally recommend calculating your tip on the pre-tax bill amount. However, many people simply tip on the total including tax for convenience. The difference is usually small. For example, on a $100 bill with 8% tax, a 20% tip on pre-tax is $20 versus $21.60 on post-tax.
Frequently Asked Questions
How much should you tip at a restaurant?
In the United States, 15% to 20% of the pre-tax bill is the standard range for sit-down restaurant service. 18% is a commonly used default. For excellent service, 20% to 25% is appropriate. For buffets, 10% is typical.
How do you calculate a 20% tip quickly?
A quick mental math trick: find 10% of the bill by moving the decimal point one place left, then double it. For a $65 bill, 10% is $6.50, so 20% is $13.00. For 15%, find 10% and add half of that amount.
How do you split a bill evenly?
Add the tip to the total bill, then divide by the number of people. For example, a $120 bill with a $24 tip (20%) split four ways would be $144 / 4 = $36 per person.
Should you tip on tax?
Technically, etiquette suggests tipping on the pre-tax amount. However, tipping on the total including tax is common and the difference is usually small. Either approach is perfectly acceptable.
Is it okay to not tip?
In the United States, servers typically earn a lower base wage with the expectation of tips. Not tipping is generally considered inappropriate for table service. If service was genuinely poor, a reduced tip of 10% combined with feedback to management is the recommended approach.
