Como Funciona Divisor de Contas
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.
Análise Matemática e Fórmulas
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.
Compute the total tip, add the initial subtotal and any taxes, and divide the final sum by the count of active participants.
Exemplos Práticos de Aplicação
Example 1: Splitting a dinner among 4 friends with a 15% tip
- Bill Subtotal: $100.00, Tip: 15%, People: 4
- Calculate tip amount: $100.00 × 0.15 = $15.00
- Grand Total: $100.00 + $15.00 = $115.00
- Divide by 4: $115.00 ÷ 4 = $28.75 per person
Example 2: Bill with tax and custom tip splits
- Subtotal: $80.00, Tax: $8.00, Tip Rate: 20%, Diners: 2
- Tip Amount: $80.00 × 0.20 = $16.00
- Grand Total: $80.00 + $8.00 + $16.00 = $104.00
- Divide by 2: $104.00 ÷ 2 = $52.00 per person
