The 30% rule. Rent is sustainable when it stays under 30% of net income. We take that 30% of the salary and divide it by the barri's rent per m² to get the most space you could rent without overpaying, and what kind of home that is.
Prices (registered). Average contract rent per m² and barri, 2025 — deposits lodged with INCASÒL (Government of Catalonia). It is what the average tenant with a lease pays, capped renewals included.
What you'd pay moving now. Asking prices for new leases are higher. That is why we also show the district's asking price (idealista): the gap between registered and asking is the "lease lottery".
