Room rent points calculator

A room in a shared house is scored under a different system from a self-contained home, and the differences work against tenants who assume otherwise. Communal space is divided by the number of rooms sharing it, energy performance is scored per square metre of your own share, and there is a set of deductions — for a small room, poor daylight, or a bathroom you can only reach through the landlord's living room — that has no equivalent in the ordinary system.

Your own spaceYour room (m²)The room you rent exclusively. Under 8 m² a deduction applies — see below.

Shared spacesRooms sharing these spacesThe number that decides everything: communal space is divided by this, so the same kitchen is worth four times less in an eight-room house than in a two-room one.

Maximum lawful bare rent: EUR 0,00

A room is always in the social sector, whatever it scores. A surcharge raises the lawful rent but never moves the room out of rent regulation.

What to do about it

A points total on its own changes nothing. Which route is open to you depends on one date — when your tenancy started — so fill that in and the deadlines below are computed for you.

Tenancy start dateThe date on the contract. Everything below turns on this.Address of the propertyYour nameLandlord or agency

Why the number of housemates matters so much

Every communal square metre is divided by the number of rooms entitled to use it. A generous 40 m² kitchen-living room is worth 20 points to a tenant in a two-room house and 5 points to a tenant in an eight-room one — for exactly the same kitchen. If a landlord adds rooms to a house, the lawful maximum rent of every existing room falls. That is the single most useful thing to know before signing.
