Master Bedroom Rent Premium Calculator — frequently asked questions
How does this master bedroom rent split calculator work?+
It starts from an equal rent split, estimates the master bedroom's advantage from size, private bath, closet space, balcony, parking, noise, and natural light, then shifts that premium while keeping the total rent unchanged.
How much extra should someone pay for the master bedroom?+
The fair premium depends on the rent, how much larger the room is, whether it has a private bath, storage, outdoor space, parking, and whether it is quieter or brighter than the other bedrooms.
Can I customize the value of a private bath or parking spot?+
Yes. The free calculator uses balanced default values. Pro unlocks custom values for size, closet space, private bath, balcony, parking, noise, light, and rounding.
Is my rent or roommate information sent to a server?+
No. Rent, bedroom sizes, amenity values, and premium calculations happen entirely in your browser.
