How to Calculate a Tip
Calculating a tip manually requires multiplying your bill by the tip percentage. For a 20% tip, multiply the bill by 0.20. For 18%, multiply by 0.18. Then add the tip to get the total.
Example: Bill = $85.50 · Tip = 20% Tip amount = $85.50 × 0.20 = $17.10 Total = $85.50 + $17.10 = $102.60 Per person (4 people) = $102.60 ÷ 4 = $25.65
The quick mental math trick
To quickly calculate a 20% tip: move the decimal point one place left (10% of the bill), then double it. For $85.50: 10% = $8.55 → doubled = $17.10. For 15%: find 10%, then add half of that.
When and how much to tip
In the United States, tipping at restaurants is a social norm and servers typically earn most of their income from tips. 15-20% of the pre-tax bill is standard. For exceptional service, 25% or more is appropriate. In the UK, 10-15% is typical. In many European countries and Japan, tipping is not expected or customary.
Frequently Asked Questions
How much should I tip at a restaurant?
In the US, the standard tip is 15-20% of the pre-tax bill. 15% for adequate service, 18% for good service, 20% for great service, and 25%+ for exceptional service. For poor service, you can tip less or speak with a manager.
Should I tip on the pre-tax or post-tax amount?
Technically, tip should be calculated on the pre-tax amount since servers didn't 'earn' the tax portion. However, in practice, most people tip on the total bill including tax. The difference is usually small — on a $100 bill with 8% tax, it's only about $1.60.
How do I split the bill with tip?
Enter the total bill amount, tip percentage, and number of people in this calculator. It automatically calculates the total including tip and divides it equally among all people.
Do I tip on alcohol?
Yes, tip on the full bill including drinks. Bartenders and servers put effort into preparing drinks too. At a bar where you're ordering drinks only, $1-2 per drink or 15-20% is appropriate.
Is tipping mandatory?
In the US, tipping is not legally mandatory but is a strong social norm. In many other countries — Japan, South Korea, China, many European nations — tipping is not expected and can sometimes be considered rude. Always check local customs when travelling.
