Formula & Mathematical Methodology: Pre-Tax Tip & Group Split Equations

Total per Person = Subtotal × (1 + Tip%100 + Tax%100)People
Tip = Subtotal × (Tip% / 100); Tax = Subtotal × (Tax% / 100); PerPerson = (Subtotal + Tax + Tip) / People
  • Subtotal: Pre-tax food and drink total
  • People: Number of diners splitting the bill

Rounding: Rounded to 2 decimal places.

Worked Example: $120 Pre-Tax Bill with 18% Tip and 8.25% Tax Split 4 Ways

Four friends split a $120 pre-tax dinner bill with 8.25% sales tax and an 18% tip.

  1. Tip (on $120 pre-tax) = $120 × 0.18 = $21.60 ($5.40/person).
  2. Sales Tax = $120 × 0.0825 = $9.90.
  3. Grand Total = $120.00 + $21.60 + $9.90 = $151.50 → $37.88 per person.
Result: Grand total is $151.50 ($37.88 per person, including $5.40 tip each).
