Gross vs. Net Rental Yield in Spain: What's the Real Difference?

If you've compared rental listings in Spain, you've probably seen two different-looking numbers for what feels like the same thing: gross yield and net yield. They can differ by more than a full percentage point on the exact same property — and the gap is exactly where a rental that "looks great" turns out to be mediocre once you run the real numbers.

Gross yield: the headline number

Gross yield is the simplest possible measure of a rental's return — annual rent divided by what it costs you to acquire the property:

gross yield = annual rent ÷ total acquisition cost

It's easy to calculate and useful for a first-pass comparison across listings, but it ignores everything that actually happens after you buy: the property sitting empty between tenants, community fees, IBI (property tax), insurance, maintenance. Two properties with identical gross yield can have very different real returns once those costs are accounted for.

Net yield: what's left after the costs that actually happen

Net yield starts from the same rent figure but subtracts the costs of actually running the rental — typically vacancy and annual operating expenses — before dividing by the acquisition cost:

net yield = (annual rent − vacancy loss − annual expenses) ÷ total acquisition cost

This is the number that reflects what you'd actually pocket in a normal year, which is why it's almost always lower than the gross figure — sometimes substantially.

A worked example

Take a property priced at €180,000, with typical Spanish buying costs of 10% (ITP or VAT, notary, land registry, and gestoría fees — a common back-of-envelope range, not a fixed number; verify against your specific region and property type), renting for €850/month, with one month of vacancy a year and €1,400 in annual expenses (community, IBI, insurance, maintenance):

That's a 1.2-point gap between the headline number and the real one — on a completely ordinary, unremarkable property. On a listing with higher fees or a longer typical vacancy, the gap gets wider.

The detail most calculators skip: what's in the denominator

Here's a nuance worth knowing, because it changes the answer: should the denominator be just the purchase price, or the purchase price plus buying costs?

Using price alone flatters the yield — it pretends the ITP/VAT, notary, and registry fees you actually paid don't count as capital you put into the deal. They do. HazNúmeros' calculator uses total acquisition cost (price + buy costs + any initial renovation) as the denominator for both gross and net yield, because that's the actual cash you committed — not just the number on the purchase contract. It's a stricter standard than some quick online calculators use, and it's the reason our numbers sometimes look slightly lower than a figure you might see elsewhere for the same property.

What net yield here does not include

This is important enough to say plainly: the net yield above is before income tax. Spain taxes rental income through IRPF (for resident landlords) or a separate non-resident rate, with deductions and reductions that can change your after-tax return meaningfully — sometimes by more than the gross-to-net gap itself. We're building a dedicated tax guide and calculator for this; until then, treat the net yield figure here as pre-tax operating return, not your final take-home number.

Quick answers

Is a 4% net yield good for a Spanish rental? It depends heavily on the city and property type — coastal tourist areas and prime city centers often run lower (buyers are partly paying for capital appreciation potential), while smaller cities and secondary neighborhoods can run meaningfully higher. There's no single "good" number without city-by-city context.

Why is my gross yield different from what a listing site shows me? Most likely a different denominator (price only vs. price + buying costs) or a different rent assumption (asking rent vs. realistic achievable rent). Always check what's actually being divided by what before comparing two sources.

Does net yield include mortgage payments? Not in this calculation — this is yield on total cash invested, treating the purchase as if bought outright. If you're financing the purchase, mortgage interest and principal are a separate cash-flow layer on top of this number, not part of it.
