What the land cost ratio is and how it is calculated
The land cost ratio (repercusión de suelo) is the price of the plot divided by the buildable area it allows:
| Item | Example |
|---|---|
| Land price | €2,400,000 |
| Buildable area | 4,000 buildable m² |
| Land cost ratio | €600 per buildable m² |
Two technical clarifications. The relevant buildable area is what can actually be materialised under planning rules, not the theoretical figure in the sales listing: alignments, setbacks, height limits and land transfers can reduce it. And the ratio is calculated on above-ground buildable m² as the dominant convention; if the project includes basements with value (sellable parking spaces), their treatment must be made explicit to avoid comparing heterogeneous figures.
Observed ranges by area type
The dispersion of land cost ratios is much greater than that of construction costs, because it incorporates each market's expected sales price:
| Area | Indicative land cost ratio |
|---|---|
| Prime areas of major capitals and high-pressure coastline | €250 – 600/m² and above |
| Intermediate and consolidated peri-urban areas | €100 – 250/m² |
| Low-demand inland Spain | From €20/m² |
At the top of the scale, the land ratio rivals or exceeds the construction cost; at the bottom, it is almost marginal. That asymmetry explains why the same development is feasible in one city and unfeasible thirty kilometres away: the works cost practically the same, the land does not.
The developer's balance rule
The classic feasibility reading orders the sales price into three approximate thirds: one third land, one third construction and one third for the rest (fees, expenses, financing and margin). It is a simplification, but it works as a quick test: when the land ratio clearly exceeds one third of the expected sales value per m², the operation requires either exceptional sales or compression of some other item, and both hypotheses deserve suspicion.
The practical corollary: the maximum payable price for land is deduced from the sales value and the construction cost, never the other way round. Buying expensive land and expecting the works to "adjust" inverts the logic and usually ends up compressing quality or margin. The works ranges feeding this calculation are those of this guide: multifamily buildings between €900 and €1,300/m² PEM above ground in 2026.
The essentials
The land cost ratio turns land into a magnitude comparable with the works and with sales, and that comparison is the heart of any feasibility study. Three checks before using it: real rather than theoretical buildable area, a clear convention on below-ground space, and coherence of the land-construction-sales trio with the rule of thirds as a first filter.
