Questions people ask
How do you split rent fairly with different room sizes?
Split a share of the rent equally for the kitchen, lounge and bathrooms everyone uses, and divide the rest by each bedroom's size.
What share should be split equally?
Often 30% to 50%. The more time everyone spends in shared spaces, the larger the equal share should be.
What about an en-suite bathroom or balcony?
Add its area to that room's size so its occupant pays a bit more.
