Calculate a fair rent split for a couple and single roommate in a 2-bedroom home. Equitably splits private square footage and shared common space.
Couple & Single: Rent Split
Calculate a fair rent split for a couple and single roommate in a 2-bedroom home. Equitably splits private square footage and shared common space.
Why this calculation is mathematically fair
The dual-pool model splits the apartment into 50% private bedrooms and 50% shared living spaces. The couple pays for 1 private room based on its size and amenities, but pays 2 human shares of the common area pool (kitchen, living room, laundry). This avoids both extremes: splitting 50/50 by room (unfair to the single roommate) or 33/33/33 equally (unfair to the couple who only get 1 bedroom).
Frequently asked questions
Why should a couple pay more than 50% for a 2-bedroom apartment? +
Because an apartment is not just bedrooms. Two people occupy kitchen space, refrigerator shelves, living room couches, and shared bathrooms twice as much as a single occupant. Paying two shares of the shared living pool keeps it fair for everyone.
Should a couple pay two-thirds (66.7%) of the rent? +
No. Charging a couple two-thirds of the total rent treats them as if they rented two separate private bedrooms. They share one room, so their private room charge should reflect just that single bedroom.
How should utilities and internet be split with a couple? +
Utilities like electricity, water, gas, and household cleaning supplies are consumed per person, so they should generally be split in 3 equal parts (or adjusted if someone works from home full-time).
