Comment Fonctionne Partage d'Addition

To split a bill, you first calculate the total tip based on a percentage of the pre-tax or post-tax amount. This tip is added to the bill subtotal to find the grand total, which is then divided by the number of active participants in the group.

Analyse Mathématique et Formules

The calculation involves finding the tip amount as a percentage of the subtotal, adding any sales tax, and then dividing the cumulative sum by the number of diners.

Formule PrincipalePer Person Share = (Subtotal + (Subtotal × Tip %) + Tax) ÷ Total People

Compute the total tip, add the initial subtotal and any taxes, and divide the final sum by the count of active participants.

Exemples Pratiques d'Application

Example 1: Splitting a dinner among 4 friends with a 15% tip

  1. Bill Subtotal: $100.00, Tip: 15%, People: 4
  2. Calculate tip amount: $100.00 × 0.15 = $15.00
  3. Grand Total: $100.00 + $15.00 = $115.00
  4. Divide by 4: $115.00 ÷ 4 = $28.75 per person

Example 2: Bill with tax and custom tip splits

  1. Subtotal: $80.00, Tax: $8.00, Tip Rate: 20%, Diners: 2
  2. Tip Amount: $80.00 × 0.20 = $16.00
  3. Grand Total: $80.00 + $8.00 + $16.00 = $104.00
  4. Divide by 2: $104.00 ÷ 2 = $52.00 per person

Erreurs Courantes à Éviter

  • Double-Tipping on Tax: Calculating the tip on the post-tax bill instead of the pre-tax subtotal, resulting in an accidentally higher gratuity.
