Understanding Gratuity and Bill Splitting
Tipping is standard etiquette across hospitality and restaurant industries worldwide. This calculator allows dining groups to compute fair gratuity based on bill subtotal and distribute the final payment evenly per guest without manual math errors.
Mathematical Formula
Tip Amount = Bill × (Tip% ÷ 100)
Total Due = Bill + Tip Amount
Per Person = Total Due ÷ Number of Guests
Total Due = Bill + Tip Amount
Per Person = Total Due ÷ Number of Guests
Step-by-Step Worked Example
Step 1: Bill subtotal is $85.00.
Step 2: Desired gratuity is 18% ($85.00 Ã 0.18 = $15.30).
Step 3: Total bill with tip equals $100.30.
Step 4: Divided between 2 diners = $50.15 each.
Important Considerations & Limitations
Calculation assumes all diners share equal responsibility for food and beverages. Tax considerations vary by municipal jurisdiction.
