Tip Calculator

To calculate a tip, multiply the bill amount by the desired percentage. Example: on a €50 bill, a 15% tip is €7.50, for a total of €57.50.
Explanation
Tipping customs vary a lot by country: in the United States, 15-20% is a common range in restaurants, while in France service is legally included in the displayed price (since a 1955 law), and tipping is a purely optional gesture, typically 5-10%, to reward good service — never an obligation there. This calculator applies a straightforward percentage to the bill amount, then splits the total among diners if you're sharing the check — handy for a dinner with friends. If you're instead trying to calculate a discount or a price markup, check out our percentage calculator, which relies on the same underlying calculation.
Example: a €50 bill split between 2 people
Inputs
Bill: €50. Tip: 15%. Diners: 2.
Calculation
First calculate the tip amount: €50 × 15% = €7.50. Add it to the bill to get the total: €50 + €7.50 = €57.50. Finally, divide that total by the number of people: €57.50 ÷ 2 = €28.75 each.
Result
The tip is €7.50, for a total of €57.50, or €28.75 per person.
Frequently asked questions
How much should I tip?
This varies significantly by country and context. In the United States, 15-20% is customary in a sit-down restaurant for satisfactory service. In France, service is included in the displayed price by law, and 5-10% is a common optional gesture rather than an expectation. Always check local customs for where you are.
How do I split a tip fairly between several people?
This calculator divides the total (bill + tip) by the number of diners for an even split. If some diners ordered very different amounts, it may be fairer to split proportionally to what each person actually consumed rather than equally.
Is the tip calculated before or after tax?
In practice, tips are usually calculated on the total amount shown on the bill, tax already included — this calculator follows that same convention.
