Calcul Pourboir Usa

In the United States, gratuity (often called a "tip" or "pourboir") is a customary practice to show appreciation for good service. This guide explains how to calculate the proper gratuity for your meal, including standard tip percentages and how to use our gratuity calculator.

How to Calculate US Gratuity

Calculating gratuity in the US is straightforward. The standard method is to calculate a percentage of the total bill before tax. Here's how to do it:

Determine the total bill amount before tax.
Choose a tip percentage based on the quality of service (15-20% is typical).
Multiply the bill amount by the tip percentage to get the tip amount.
Add the tip amount to the bill to get the total amount to pay.

Note: Some restaurants may include tax in the bill, so check with your server if you're unsure whether to calculate gratuity on the pre-tax or post-tax amount.

Standard Tip Percentages

The standard gratuity percentages in the US vary depending on the quality of service and the type of establishment:

Service Quality	Tip Percentage
Poor	10-12%
Fair	12-15%
Good	15-18%
Excellent	20% or more

In some cases, such as when splitting the bill, you may want to calculate the tip based on the total bill before tax and then divide it among the people paying.

Formula Used

Gratuity Amount = Bill Amount × (Tip Percentage ÷ 100)

Total Amount to Pay = Bill Amount + Gratuity Amount

For example, if your bill is $50 and you want to leave a 15% tip:

Gratuity Amount = $50 × (15 ÷ 100) = $7.50

Total Amount to Pay = $50 + $7.50 = $57.50

Worked Examples

Example 1: Standard Meal

Bill Amount: $45.00

Tip Percentage: 18%

Gratuity Amount: $45 × 0.18 = $8.10

Total Amount to Pay: $45 + $8.10 = $53.10

Example 2: Splitting the Bill

Bill Amount: $80.00

Tip Percentage: 15%

Number of People: 4

Gratuity Amount: $80 × 0.15 = $12.00

Total Amount to Pay: $80 + $12 = $92.00

Amount per Person: $92 ÷ 4 = $23.00
