Tip Calculator

What this calculator does

The Tip Calculator finds the tip amount for a restaurant bill, the total after the tip, and the amount each person owes when the bill is split. You can enter any tip percentage and divide the result among up to 100 people.

The calculator also shows a quick-reference table for common tip percentages from 5% to 50%. This makes it easy to compare a standard 15% or 20% tip with a more generous amount without re-entering the bill.

How to use this calculator

1. Enter the bill amount.
2. Enter the tip percentage you want to leave.
3. Enter the number of people sharing the bill.
4. Click Calculate.

The default example uses a $55 bill, a 15% tip, and one person. The tip is $8.25, the total is $63.25, and the per-person total is also $63.25. If the same bill were split four ways with a 20% tip, each person would owe $16.50 before any additional rounding.

Tip formulas

Tip amount      = bill × tip percentage ÷ 100
Total           = bill + tip amount
Tip per person  = tip amount ÷ number of people
Total per person = total ÷ number of people

The quick table applies the same formula to 5%, 10%, 12%, 14%, 15%, 18%, 20%, 25%, 30%, and 50% tips. The bill amount stays fixed while the percentage changes.

What the results mean

The tip amount is the extra money added for service. The total is what the table will charge before any separate fees. The per-person figures divide both the tip and the total evenly. The calculator does not round each person's share up to a whole dollar; it displays the exact share so you can decide how to round.

Whether you tip on the pre-tax or post-tax amount is a personal and regional convention. The calculator uses whichever bill amount you enter, so enter the subtotal if you prefer to tip before tax.

Assumptions and limitations

• The tip percentage is applied only to the bill amount entered. Tax, delivery fees, and service charges are not added automatically.
• The split is even. It does not account for people ordering different items.
• The number of people must be a whole number from 1 to 100.
• The calculator does not enforce a minimum or maximum tip. A 0% tip is allowed.
• Rounding is left to the user; the displayed per-person values may include fractions of a cent.
• Tipping customs vary widely by country and type of service.

Frequently asked questions

Should I tip before or after tax?

There is no single rule. Many people tip on the pre-tax subtotal, while others use the final total for simplicity. Enter the amount you want the percentage applied to, and the calculator will use it consistently.

How do I split a bill unevenly?

This calculator splits evenly. For an uneven split, calculate each person's share separately or use the total tip amount as a starting point and assign amounts manually.

Why does the per-person total have more than two decimals?

The calculator shows the exact mathematical share before cash rounding. If you are paying in cash, round each person's share to a convenient amount and adjust the total slightly.
