Tip Calculator with Split Bill

About the Tip Calculator

Tipping is an essential part of dining and service culture across North America and many parts of the world. Our Tip Calculator allows diners, travelers, and event organizers to quickly calculate exact gratuity amounts, grand totals, and fair per-person splits with total transparency.

Choose from popular preset tip rates (10%, 15%, 18%, 20%, 25%) or enter a custom percentage. If dining with colleagues or friends, adjust the Split Between headcount to see the exact amount each person owes in food and tip.

Key Tipping & Bill Splitting Formulas

Calculating tips accurately relies on these straightforward mathematical formulas:

How to Calculate a Restaurant Tip Step-by-Step

1. Determine Pre-Tax Subtotal: Look at your restaurant receipt and use the subtotal before sales tax for traditional tipping.
2. Choose Your Gratuity Level: 15% is standard for adequate service, 18% for good service, and 20% or higher for exceptional hospitality.
3. Calculate the Tip: Multiply the subtotal by your chosen percentage as a decimal (e.g. $80.00 x 0.20 = $16.00 tip).
4. Add to Get Grand Total: Add the tip to your bill subtotal (and any applicable sales tax): $80.00 + $16.00 = $96.00.
5. Split If Dining in a Group: Divide the final total by the number of paying guests (e.g. $96.00 ÷ 4 = $24.00 per person).

Worked Example: A dinner bill comes to $65.00. Adding an 18% tip gives a gratuity of $65.00 x 0.18 = $11.70, resulting in a grand total of $76.70. If split between 2 people, each pays $38.35.

Frequently Asked Questions (FAQ)

What is the standard tip at a restaurant in the United States?

In the United States, 15% to 20% is the accepted standard for table service. 15% is typical for acceptable service, 18% for good service, and 20% or higher for outstanding service or fine dining.

Should tip be calculated before or after sales tax?

Etiquette guidelines recommend calculating tips on the pre-tax food and beverage subtotal. Tipping after tax means you are paying gratuity on government taxes, although many guests tip on the bottom line for simplicity.
