Fair Rent Breakdown
Total: $3000 / moThe 50/50 Balanced Formula
Half of your rent pays for equal access to the kitchen, living room, and amenities. The other half is distributed based on private square footage and exclusive perks.
Private Bathroom Premium
In Balanced mode, a private bathroom increases that room's weighted score by 25%; a balcony adds 8%.
Couple Fair Share
The Couple option increases that room's weighted score by 30% in Balanced mode. Compare the result with your own household agreement.
How does the 50/50 rent split work?
Balanced mode divides half the rent equally between bedrooms. The other half follows room size, with optional weights for a private bathroom, balcony, or couple. Compare the result with the equal and room-size methods before agreeing on a split.
How does a private bathroom affect the calculation?
In Balanced mode, the calculator multiplies that bedroom's weighted score by 1.25. A balcony multiplies it by 1.08. These are model assumptions for a household discussion, not fixed market rates.
How does the calculator handle a couple sharing a bedroom?
Selecting Couple multiplies that room's weighted score by 1.30 in Balanced mode. The equal half is still divided by bedroom, so review the result with everyone in the household.
