How to Calculate a Tip
Calculating a tip is straightforward multiplication:
- Determine the bill amount (pre-tax subtotal is traditional, but post-tax is also acceptable).
- Choose your tip percentage: 15% for adequate service, 18% for good service, 20% for great service, 25% for exceptional service.
- Multiply: Bill amount x tip percentage = tip amount.
- Add to bill: Bill + tip = total amount due.
- Split if needed: Divide the total by the number of people.

Frequently Asked Questions
How much should I tip?
In the United States, the standard tip for sit-down restaurants is 15-20% of the pre-tax bill. For excellent service, 20-25% is common. Buffets typically warrant 10%, and takeout 0-10%. For delivery, 15-20% or a minimum of $3-5 is standard. Always tip on the pre-tax amount.
Do you tip before or after tax?
Etiquette experts recommend tipping on the pre-tax amount (subtotal). The tax is paid to the government, not the server, so it should not factor into the tip. However, tipping on the total (post-tax) is also acceptable and makes mental math easier — the difference is usually small.
How do you calculate a 20% tip?
To calculate a 20% tip: multiply the bill amount by 0.20. For example, a $50 bill x 0.20 = $10 tip. A quick mental math shortcut: move the decimal point one place left to get 10%, then double it. $50 to $5.0 to $10.00 tip.
How do you split a bill with tip?
First, calculate the total bill including tip. Then divide by the number of people. For example: $80 bill + $16 tip (20%) = $96 total / 4 people = $24 per person. For simplicity, you can round up per-person amounts to the nearest dollar.
