Split the rent by room, not by headcount

Bigger room, bigger share. Enter the total rent and the size of each bedroom; add a bump for a private bathroom or a balcony and the shares rebalance.

Rent split by room

Filled in with an example. Replace it with your own numbers.

NameRoom size (sq ft)Bump (%)
Big room with bath$1,591.07
Middle room$1,125.00
Small room$883.93
Total$3,600.00

Share of rent equals share of bedroom area after the bump for a private bath or balcony. Common space is assumed shared equally.

Questions

How is the share calculated?

Each room's share of the rent equals its share of the total bedroom area, after any adjustments. Common space is assumed to be shared equally, so it does not change the ratio.

What if we would rather split evenly?

Enter the same size for every room. The calculator then gives everyone the same share.
