How to Split Rent Fairly by Square Footage: SHARE Calculator
Split rent fairly based on room size and shared space.
Why this tool?
This simple calculator is my small contribution to help those navigating the housing crisis. Finding a place is hard enough; splitting the rent shouldn't add to the stress.
If you are looking to rent a place with others, this tool provides a fair starting point for dividing costs. It calculates each person's share based on their private room size and the common areas.
It's meant to save time and energy in cities where finding accommodation is already a challenge. If you find it useful, please share it with others!
Frequently Asked Questions
How to split rent fairly in a shared apartment?
The fairest way to split rent is based on room size. Calculate each room's proportion of the total private square footage, then factor in shared areas. The SHARE Calculator automates this by dividing rent proportionally based on room dimensions and a configurable shared space value.
How to share rent with roommates and common areas?
When figuring out how to share rent, common areas like living rooms and kitchens should be factored in. The SHARE Calculator uses a configurable 'shared space value' (0-1) to determine how much weight shared areas carry. A value of 0.75 means shared space is worth 75% of private room value.
How do subjective features like a balcony or big windows affect the rent split?
The SHARE Calculator intentionally focuses on the objective math of square footage and shared areas to provide a fast, fair baseline estimate. Once you have this baseline, you can easily adjust the final price with your flatmates to account for subjective features (like sunshine or an ensuite bathroom) without overcomplicating the initial calculation.
