Retirement pension spending will rise from €112,861 million in 2024 to €422,315 million in 2050, according to projections by the Ministry of Inclusion, Social Security and Migration. No political party has yet specified how it plans to finance that increase.
There is a figure worth keeping handy before discussing pensions at any bar: **€112,861 million**. That is what retirement benefits cost in Spain in 2024. And there is another worth bearing in mind even more: **€422,315 million**. That is what, according to estimates by the Ministry of Inclusion, Social Security and Migration, those same benefits will cost in 2050. The bill almost quadruples in twenty-five years. It is not a projection from a foreign think tank or an opposition calculation: it comes from the very department headed by **Elma Saiz**.
The interesting question is not whether spending will rise. That is beyond dispute. The question is who pays for it and how. And there, for now, silence. Parties have promised to protect pensions during the campaign for the November 29 elections, but none has put a concrete mechanism on the table to tackle the increase. Promising that pensions will not be touched is easy. Explaining where the money will come from, considerably less so.
## The burden on the economy: from 12.7% to 15.3% of GDP
The increase is not measured only in nominal euros. Pensions will gain weight within the overall economy. In 2024 they accounted for **12.7% of GDP**. Official projections point to them reaching **15.3% in 2050**, the year in which spending peaks and up to which the system's revenue scheme was designed in the last reform. Across the whole period, average spending will stand at around 14% of GDP.
The **Independent Authority for Fiscal Responsibility (AIReF)** works with higher forecasts. It calculates that spending on this type of benefit amounted to 13% of GDP in 2025 and will reach **16.4% in 2050**. That is, half a point more than the Ministry says for the same year. It is not a dramatic difference, but it marks the direction: official estimates may fall short.
The trend does not stop at mid-century. By 2070, the total cost of pensions could reach **€824,999 million**, nearly seven times more than today. Broken down by type of retirement, the bulk of the outlay at mid-century will correspond to standard retirement benefits, although early and delayed retirement will also gain weight.
## What has already grown in this term
This is not a film that starts in 2050. The pension bill has been growing during **Pedro Sánchez's** term. Retirement benefit spending rose from **€122,365 million in 2023 to €138,816 million in 2025**, up 13.5%. In the first eight months of 2026, Social Security had already allocated **€91,351 million** to paying these benefits.
The future increase is driven by several factors. The main one is the retirement of the baby boom generation, which accounts for around **31% of the Spanish population**. Their pogre exit from the labour market will push the number of pensioners to unprecedented levels. Projections suggest Spain could have up to **17.7 million pensioners** in the coming decades. At the end of 2025 there were already 6.5 million retirees, representing 69% of all benefit recipients. The figure rises to 6.65 million in August 2026.
Other factors also play a role: rising life expectancy, greater female labour participation, and the fact that new generations of retirees reach retirement with longer contribution records and higher salary bases. Added to this is the annual uprating of pensions in line with CPI, which drives the growth of the average pension year after year. In 2026 benefits rose by **2.7%**. For 2027, the leading research centres expect pensions to register an increase approaching **3.5%**.
## What the parties say (and what they don't)
The **Partido Popular (Spain's main conservative party)** has shown its commitment to the system. Its leader, **Alberto Núñez Feijóo**, has declared that pensions «are non-negotiable and that's it; enough», and has maintained that if he reaches La Moncloa (the prime minister's office), benefits will continue to be uprated in line with CPI. However, the party's spokesperson in Congress, **Ester Muñoz**, noted that the system «as it stands does not work and is going to collapse». Faced with that message, Feijóo reiterated that if he becomes prime minister he will guarantee the viability of the public pension system.
**Vox** proposes studying other models, such as a mixed capitalization system. Its national spokesperson for Economy, Energy and Deregulation, **José María Figaredo**, stated that the current system is «in danger of extinction» under this government. The party avoids specifying a concrete proposal, considering that the real state of public finances must first be known. Along those lines, the group's spokesperson in Congress, **Pepa Millán**, said the party's intention is that pensions be guaranteed «whatever it takes».
Minister **Elma Saiz** responds to these doubts categorically: «The pension system is sustainable, robust and equitable». She accuses the PP of backing privatization and cuts, recalling that the reform the conservatives launched in 2013 capped the annual uprating at **0.25%**. Saiz also notes that the PP voted against the reform that established pensions growing with the average CPI of the previous year and against the 2023 reform, which focused on strengthening the system's revenues. In 2021, both the PP and Vox tabled motions to block that reform from even being debated in Congress.
## An exercise in prudence
The figures projected for 2050 should be read as estimates, not as an exact snapshot of the future. Inflation, wage trends, legislative reforms, economic crises, geopolitical conflicts, migration flows or the economy's own growth could alter both total spending and the real value of the amounts forecast for several decades from now. A 2050 figure is a hypothesis, not a certainty.
What is a fact is that the pension system is at the centre of the political and economic debate of the election campaign. The parties are dropping hints about the space it will occupy in their programmes, but have not yet made public the concrete line they will take. And meanwhile, the bill keeps growing.
