Tip Calculator
This tip calculator works out the tip and the total for a restaurant bill or any service, and splits it evenly between any number of people. It can round each person's share up to the next dollar and compares common tip percentages side by side.

How to Calculate a Tip
- Tip = bill × tip percentage ÷ 100
- Total = bill + tip
- Each person pays = total ÷ number of people
Worked Examples
One person: an $80 bill with an 18% tip.
- Tip: 80 × 0.18 = $14.40
- Total: 80 + 14.40 = $94.40
Splitting the bill: a $100 bill with a 15% tip, shared by 3 people.
- Total: 100 × 1.15 = $115.00
- Each share: 115 ÷ 3 = $38.333…, rounded up to $38.34, which collects $115.02
- With “round up” on, each person pays $39, a total of $117, which makes the tip 17%

Tips for Tipping
Quick mental math
10% is the bill with the decimal point moved one place left. 15% is 10% plus half of it, and 20% is double 10%. On $64, 10% is $6.40, 15% is $9.60 and 20% is $12.80.
Check for an included service charge
Some restaurants add an automatic gratuity, often for large groups. Check the bill before adding a tip so you don’t tip twice.

Frequently Asked Questions
How do I calculate a tip?
Multiply the bill by the tip percentage as a decimal. An 18% tip on an $80 bill is 80 × 0.18 = $14.40, making the total $94.40. For a quick estimate, find 10% by moving the decimal point one place left, then double it for 20%.
How much should I tip at a restaurant?
The Emily Post Institute's guideline for wait service at a sit-down restaurant is 15 to 20 percent of the pre-tax bill, and 10 percent at a buffet. Many people tip toward the higher end, or more, for great service.
Should I tip on the total before or after tax?
Etiquette guides, including the Emily Post Institute, base the tip on the pre-tax bill, because the tax is a government charge rather than part of the service. Tipping on the total after tax is common too and gives the server a little more. Enter whichever amount you prefer.
How do I split a bill with a tip?
Add the tip to the bill and divide by the number of people. A $120 bill with a 20% tip is $144, so four people pay $36 each. If the total doesn't divide evenly, the calculator rounds each share up to the next cent so the bill is always covered.
What is 20% of $50?
$10. 10% of $50 is $5, and 20% is twice that. The total with the tip is $60.
Do I tip on a discounted bill?
When you use a coupon or a discount, many people tip on the original price before the discount, because the server did the same work. Enter the full price as the bill to do that.

Sources & Assumptions
- The Emily Post Institute — General tipping guide (sit-down wait service 15–20% pre-tax; buffet 10% pre-tax)
- Each person's share is rounded up to the whole cent, so an uneven split always covers the bill and tip; any extra cent goes to the tip. "Round up" rounds each share to the next whole dollar.
