How to Calculate a Tip and Split a Restaurant Bill
Dining out with friends and family is one of life's great pleasures, but the arrival of the check can bring uncomfortable mathematical confusion. How much should you tip the waitstaff? Should you calculate gratuity before or after sales tax? And how do you divide the total fairly when splitting the bill?
Customary Gratuity Standards
Tipping etiquette varies widely by region. In the United States and Canada, tips represent a significant portion of a service worker's income, with customary ranges typically including:
- 15%: Standard baseline for adequate service.
- 18%: Standard for good, attentive service.
- 20% or more: Excellent, exceptional service.
In many European and Asian countries, service charges are already built into food prices or wages, and a smaller nominal round-up is customary.
The Tip and Bill Split Formula
Tip Amount = Pre-Tax Bill × (Tip % ÷ 100)
Total Bill = Subtotal + Sales Tax + Tip Amount
Per Person Share = Total Bill ÷ Number of Diners
Step-by-Step Dining Scenario
Four colleagues enjoy lunch together. The food subtotal is $84.00, sales tax is $6.72 (8%), and they agree to tip 18%.
- Calculate Tip: Tip on the $84 subtotal.
$84.00 × 0.18 = $15.12 tip. - Calculate Grand Total:
$84.00 (food) + $6.72 (tax) + $15.12 (tip) = $105.84. - Divide by 4 Guests:
$105.84 ÷ 4 = $26.46 per person.
Each person contributes exactly $26.46.
