Tip Calculator
Calculate the tip and split the bill without doing math at the table. Enter the bill amount, your tip percentage, and the number of people splitting, and the calculator shows the tip amount, the total bill, and how much each person owes.
Quick answer
Tip amount = bill × (tip% / 100). Total = bill + tip. Per person = total / party size. Standard US tip is 15–20%; 18% is typical for good service.

How to calculate a tip
The math is simple: multiply the bill by your chosen tip percentage expressed as a decimal. 20% of $85 = $85 × 0.20 = $17. The total is $85 + $17 = $102. Splitting four ways is $102 / 4 = $25.50 per person.
Mental shortcuts: for a 20% tip, move the decimal one place left and double the result ($85 → $8.50 → $17). For 10%, just move the decimal one place ($85 → $8.50). For 15%, take 10% and add half of it ($8.50 + $4.25 = $12.75). Most people can calculate any common percentage this way in a couple of seconds.
Tipping norms in the US
Standard tipping norms in 2025: sit-down restaurants 15–20% (18% typical for good service), bars $1–2 per drink or 15–20% on a tab, taxis and rideshares 15–20%, food delivery 15–20% with a $5 minimum on small orders, hair salons 15–20%, hotel housekeeping $3–5 per night, valet parking $2–5, tour guides 10–20%, baristas $1 or 10–15%.
Tip inflation is real — "standard" percentages have crept up over the past two decades, and suggested tip options on card readers now often start at 18%, 22%, 25%. The right answer is what you believe is fair for the service, not whatever the screen suggests. Servers in the US depend heavily on tips because the tipped minimum wage is only $2.13 in many states.
Common mistakes
- Tipping on post-tax instead of pre-tax. Pre-tax is etiquette-correct, but the difference is usually less than a dollar per meal. Don't stress about it.
- Not tipping on a discounted meal. A 2-for-1 coupon doesn't reduce the server's workload. Tip on the full pre-discount value.
- Forgetting the automatic gratuity. Parties of 6+ often have 18% already added to the bill. Check before tipping again.
- Skipping tip on takeout. Many people tip 10% or less on takeout, which is typical. Nothing at all is fine for pickup, but 10% is appreciated if staff bagged and packed the order.
Frequently asked questions
What is a standard tip percentage in the US?
15% for acceptable service, 18–20% for good service, 25%+ for excellent. Parties of 6+ often have 18% added automatically.
Should I tip on pre-tax or post-tax?
Etiquette says pre-tax. In practice most people tip on the total for simplicity. The difference is usually under a dollar.
Do you tip on a discount or coupon?
Yes, on the pre-discount amount. The server's workload doesn't change because you had a coupon.
How do I split a bill with different orders?
Either split evenly (fair if everyone ordered similarly) or calculate each person's subtotal + tax + tip proportionally. The calculator above supports even splits.
