How Much Should You Tip?

Tipping customs vary by service type. Here are the standard tip percentages in the United States:

• Restaurants (sit-down): 15-20% of pre-tax bill
• Bars: $1-2 per drink or 15-20% of tab
• Coffee shops: $1-2 or 15-20% for specialty drinks
• Hair salons/barbers: 15-20%
• Food delivery: 15-20%, minimum $3-5
• Taxi/rideshare: 15-20%
• Hotel housekeeping: $2-5 per night
• Valet parking: $2-5

How to Calculate a Tip

The formula is simple: Tip = Bill Amount × (Tip Percentage / 100). For a $85 bill with 18% tip: $85 × 0.18 = $15.30. Total = $100.30.

Quick mental math trick: To calculate 20%, move the decimal point one place left (that's 10%), then double it. For $85: 10% = $8.50, so 20% = $17.00.

Tipping on Pre-Tax vs Post-Tax

Traditionally, tips are calculated on the pre-tax amount. However, many people tip on the total (post-tax) for simplicity. The difference is usually small — on a $100 bill with 8% tax, tipping 20% pre-tax is $20.00 vs $21.60 post-tax.

Splitting the Bill

When splitting with friends, there are two common approaches:

• Even split: Divide the total (bill + tip) equally — simplest method
• Proportional split: Each person tips based on what they ordered — fairer for unequal orders

Our calculator handles even splits. Enter the number of people and see each person's share of both the total and the tip.

When Not to Tip

Tipping is generally not expected for counter service, fast food, takeout (though appreciated), or in countries where service charges are included. Always check if a gratuity has already been added to your bill, especially for large parties.
