1. What is Proportional Bill Division?

Proportional bill division is a fair way to split expenses based on each person's income share. It ensures that each person contributes according to their financial capacity rather than splitting bills equally regardless of income differences.

2. How Does the Calculator Work?

The calculator uses the proportional division formula:

Where:

• \( Share \) — Amount the person should pay ($)
• \( Total\ Bill \) — The entire bill amount ($)
• \( Income\ Share \) — The person's percentage of total household income (%)

Explanation: The equation calculates a fair share by multiplying the total bill by the individual's percentage contribution to the total household income.

3. Importance of Proportional Division

Details: Proportional bill division helps maintain financial fairness in households with income disparities. It prevents financial strain on lower-income earners when expenses are shared.

4. Using the Calculator

Tips: Enter the total bill amount in dollars and the person's income share as a percentage (0-100). The calculator will determine their fair share of the bill.
