Mortgage costs soar: from 20,000 to 277,000 euros

The 300,000-euro mortgage interest jumps from 20,000 to 277,000

The same apartment, the same loan, the same term. The only thing that has changed is the price of money. A calculation circulating these days puts figures to what many already suspect: a 300,000-euro mortgage over 25 years that a year ago closed with total interest of 20,000 euros would now accumulate 277,000. Almost fourteen times more. The entire loan, principal included, approaches 600,000 euros. The cause is the surge in the Euribor (the Euro Interbank Offered Rate), which has moved from negative territory to exceeding 4%, and the increased cost of fixed-rate mortgages, which in some cases are already offered at over 5.7% APR.

The arithmetic does not deceive: whoever signs today pays for one and a half apartments. An independent breakdown confirms the magnitude of the gap. At a rate of 0.5%, a 300,000-euro mortgage over 30 years generates payments of 898 euros and a total of 323,828 euros. At 5.4%, the payment rises to 1,683 euros and the total skyrockets to 605,880 euros. The difference between the two scenarios exceeds 282,000 euros. Translated into plain language: at rates of 4% over 25 years, you pay for two apartments; at 5% over 30 years, one and a half apartments. Compound interest does the rest.

Why the Euribor has turned the payment into something else

The twelve-month Euribor has exceeded 4% for the first time since 2008. This detail is not minor: the majority of mortgages signed in Spain during the last decade are variable-rate. The official data used in the analysis indicate that in 2013, more than 92% of mortgages established were variable, and the average term of loans signed that year was around 23 years, meaning many borrowers still have ten years of payments ahead. The semi-annual or annual revision has reached thousands of families with the same effect: payments jumping by several hundred euros at once.

The snapshot of a typical mortgage holder illustrates this: someone who had a payment of 96 euros has gone on to pay 143. In their case, it is an anecdotal episode because they amortize at a good pace, but the pattern repeats in much larger loans. With monthly payments of 800 or 1,000 euros over 30 years, revisions have added 400 euros to the bill. This money comes from consumption, and consumption accounts for 60% of GDP. The sequence anticipated by some analyses is clear: first, the shopping basket is affected, then the car, then vacations.

Who can buy today and who is left out

The problem, according to voices in the sector, is no longer just those who signed variable-rate loans. It is those who want to sign now. With these rates, the traditional buyer—salaried, 20% down payment, stable income—finds it difficult to balance the operation. The profile sustaining demand in provincial capitals and metropolitan areas is different: buyers with liquidity, many of them foreign or non-resident, who need no financing or only minimal financing.

Some argue that this money is no longer just local savings. It points to wealth seeking refuge outside their countries of origin and to developments sold entirely before putting up a "for sale" sign. In municipalities around Madrid, 100-square-meter apartments are marketed for 350,000 or 400,000 euros plus VAT, and they sell. The paradox is evident: the residential market is sustained by demand that does not depend on credit, while the buyer who does depend on the bank is left looking through the window.

Salaries, inflation, and the equation that does not add up

The question hovering over all this is how it adjusts. If salaries do not rise at the pace of the cost of money, the equation breaks somewhere. The data cited in the analysis point to an accumulated loss of purchasing power that, between 2021 and the end of the horizon being considered, could approach 25% or 30%. Wage increases agreed upon in collective bargaining agreements for the coming years are considered insufficient to compensate for this deterioration.

This leaves two scenarios on the table. The first, a price correction that returns the market to financable levels. The second, a market that paralyzes without crashing: owners with endurance do not sell, new construction slows, development activity fades, and real estate wealth becomes illiquid. This scenario has a silent cost: less employment in construction, balance sheets beginning to reflect impairment losses, and a society aging with its wealth frozen in bricks.

The saver watches the same movie and sees something else

Not everyone loses with rising rates. Those who have paid off their housing and have savings in the bank see money finally earning interest for them. This part of the analysis is often left out of the narrative, but it explains why the debate is not unanimous: there are two viewpoints on the same central bank move, and only one of them appears in headlines. Rate hikes always have two sides, and the side of the one receiving interest rarely appears on the front pages.

The complete calculation, broken down item by item and with crossed rate scenarios, leaves a difference that surprises even those who expected the blow. The final figure depends on the term, the exact rate, and when the loan is signed. But the order of magnitude no longer allows discussion: the cost of money has rewritten the real price of housing without the price of housing moving.
