How to split rent fairly when bedrooms aren't equal

Steps

1. 01

   Measure each bedroom in square metres

   Use a tape measure or a phone measure app. Walk-in closets count for the bedroom they belong to; en-suite bathrooms count at 50%.

2. 02

   Add common-space credit (typically 10–20%)

   Common spaces (living room, kitchen, hallway) are split equally regardless of bedroom size. So divide the rent into 'private space' (bedrooms) and 'shared space' (everything else). 80/20 is a reasonable default.

3. 03

   Apply quality multipliers

   A bedroom with a window facing brick is worth less than one with a balcony. Multiply by 0.9–1.1 for objective quality differences. Don't try to weight by 'who likes it more' - keep it factual.

4. 04

   Compute the per-room rent and add the equal-share common cost

   Each person pays: (private space % × 80% of rent) + (1/n × 20% of rent). Round to nearest €5 if it makes life easier.

5. 05

   Document the split in your group description and stick to it

   Write: 'Anna 36% (master + balcony), Ben 32% (medium room), Cara 32% (small + en-suite credit)'. Never re-litigate mid-lease.

Worked example

Once the ratio is set, log rent as a recurring expense in EvenRound using the 'shares' split mode. Whoever physically pays the landlord adds the expense each month; the others square up via Settle Up.
