1. What is the Rent Split Calculator?

This calculator helps roommates in Thailand fairly divide rent based on their individual salaries. It follows the principle that those who earn more should contribute proportionally more to shared housing costs.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Total Rent — The full monthly rent amount for the shared accommodation
• Individual Salary — Your monthly salary before tax
• Total Salary — Combined monthly salaries of all roommates

Explanation: The formula calculates each person's fair share by determining what percentage of the total household income they contribute.

3. Importance of Fair Rent Splitting

Details: Salary-based rent splitting is particularly important in Thailand where income disparities between roommates can be significant. This method ensures housing costs are proportional to each person's earning capacity.

4. Using the Calculator

Tips: Enter the total monthly rent in THB, your monthly salary in THB, and the combined monthly salaries of all roommates in THB. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why split rent based on salary?
A: It creates a fair system where housing costs are proportional to each person's ability to pay, rather than simply dividing equally regardless of income differences.

Q2: Should utilities be split the same way?
A: That's up to the roommates. Some prefer to split utilities equally, while others apply the same salary-based percentage.

Q3: What if someone's salary changes?
A: The rent split should be recalculated whenever there are significant changes to individual salaries.

Q4: Is this method legally binding in Thailand?
A: No, this is just a suggested fair division method. The legal responsibility depends on the rental contract.

Q5: How to handle unequal room sizes?
A: You might first allocate rent by room size, then adjust each person's share based on the salary proportion for their room.
