How It Works
The Tip Calculator calculates appropriate gratuity for dining and hospitality services, computes total payment due, and splits the bill evenly across parties.
Choose from standard gratuity presets (15%, 18%, 20%) or enter a custom rate, with optional rounding up to clean whole dollar values.
Formula & Calculation
Gratuity & Bill Split Formulas
Total = Bill + (Bill × TipRate)
Tip Amount=Bill × (Tip Percentage / 100)
Total Bill=Pre-tip Bill + Tip Amount
Share Per Person=Total Bill / Number of People
Step-by-Step Example
Example: 4-Person Dinner ($120.00 Bill, 20% Tip)
Calculating gratuity and equal dinner splits:
Step 1: Calculate total tip:
$120.00 × 0.20→ $24.00 gratuityStep 2: Calculate total payment:
$120.00 + $24.00→ $144.00 totalStep 3: Split evenly across 4 diners:
$144.00 / 4 people→ $36.00 per person ($30 food + $6 tip)Each diner pays $36.00, covering a $30.00 meal share and $6.00 tip.
Assumptions & Edge Cases
- Pre-Tax vs. Post-Tax Tipping: Etiquette tradition generally recommends tipping on the pre-tax food and beverage subtotal. However, many diners tip on the post-tax total for simplicity.
- Even Split Rounding: When splitting an odd total across multiple people, pennies are allocated to ensure the exact sum of individual payments equals the total bill.
