1. What is Income-Based Rent Splitting?

Income-based rent splitting is a fair way to divide rent among roommates or partners based on each person's income. This method ensures that those who earn more contribute proportionally more to the household expenses.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Total Rent — The combined rent amount for the household
• Individual Income — Your personal after-tax income
• Total Income — Combined after-tax income of all household members

Explanation: The formula calculates what percentage of the total household income you earn, then applies that percentage to the total rent.

3. Benefits of Income-Based Rent Splitting

Details: This method creates a fair living situation where no one is overburdened by rent payments relative to their income. It's particularly useful for couples with different income levels or roommates with varying financial situations.

4. Using the Calculator

Tips: Enter the total monthly rent amount, your monthly after-tax income, and the combined monthly after-tax income of all household members. All values must be positive numbers.

Q3: What if someone's income changes significantly?
A: The split should be recalculated whenever incomes change substantially to maintain fairness.
