How It Works
Enter the bill total and desired tip percentage, and the calculator multiplies them to find the tip. You can also reverse the calculation to find the original bill or the tip percentage when you know the other two values. In the U.S., the customary restaurant tip ranges from 15% to 20% of the pre-tax bill.
Example Problem
Your dinner bill is $65. You want to leave an 18% tip. How much is the tip?
- Tip = $65 × 18 / 100 = $11.70
- Total with tip: $65 + $11.70 = $76.70
Frequently Asked Questions
How much should you tip at a restaurant?
In the U.S., 15–20% is standard for sit-down restaurants. 15% is the minimum for adequate service, 18% is common, and 20% or more rewards excellent service. Many restaurants auto-add 18% for parties of six or more.
Should I tip on the pre-tax or post-tax amount?
Etiquette experts generally recommend tipping on the pre-tax subtotal. However, tipping on the total including tax is common and simpler, and the difference is usually small.
How do I quickly calculate a 20% tip?
Move the decimal one place to the left (that gives you 10%) and double it. For a $45 bill: 10% is $4.50, so 20% is $9.00.
