Ending Roommate Rent Drama With Math
Splitting rent equally sounds simple on paper — until one roommate gets a master bedroom with a private bath and walk-in closet, while another gets a converted den with paper-thin walls.
The Problem With "Just Divide By N"
Most roommates default to dividing rent by head count because negotiating feels awkward. But this almost always leaves someone feeling resentful. In high-cost US rental markets like New York, San Francisco, Austin, and Seattle, a couple hundred dollars a month makes a huge difference.
Traditional rent splitters are often rigid 3-step forms built a decade ago. They don't support modern living situations like couples sharing one bedroom, mixed income brackets, or detailed amenity adjustments.
Our Scientific Approach
My Rent Splitter is based on published consumer valuation studies and fair-division economics. We break your apartment into two components:
- Private Space Value: Weighted by square footage, en-suite vs. shared bathrooms, closet dimensions, natural lighting, and parking privileges.
- Common Shared Space: Living areas, kitchens, balconies, and entryways, split equally per occupant regardless of bedroom tier.
When combined, each roommate pays for exactly what they use — leaving everyone confident that their share is mathematically fair.
100% Privacy by Design
Financial conversations with roommates should be private. That's why:
- No user account or login is ever required.
- Calculations execute 100% client-side inside your browser.
- Shareable URLs encode parameters directly in the hash/query — nothing is saved to a server database.
