// How to Calculate Tip Splits
Tipping is standard protocol when dining at sit-down restaurants, bars, and cafés. When dining in groups, splitting the total check can be a chore. This widget automates the math so you can split the costs quickly.
Mathematical Formula:
Tip Amount = Bill Subtotal × (Tip% / 100)
Grand Total = Bill Subtotal + Tip Amount
Per Person Share = Grand Total / Guests
Worked Example: $100 Bill split between 2 people with a 15% tip
Suppose you and a friend dine out, and the bill is $100.
1. Find the service gratuity: $100 × (15 / 100) = $15.
2. Find the grand total bill: $100 + $15 = $115.
3. Split between 2 guests: $115 / 2 = $57.50.
Each person pays exactly $57.50.
// Frequently Asked Questions
▸Should you tip on the pre-tax or post-tax total?
Standard etiquette dictates tipping based on the pre-tax bill total, so you are only rewarding the food and service, not the government tax.
▸Is service charge the same as a tip?
No. In many restaurants, a service charge is automatically added to the check (especially for parties of 6 or more). If a service charge is already included, tipping is optional.
▸What is a standard gratuity rate?
In North America, standard tipping is 15% for good service and 18-20% for exceptional service. In Europe and Asia, service is often built into the menu price or added as a flat cover charge.
