Social Security allows workers to continue contributing beyond their ordinary retirement age through what is known as delayed retirement, which gives the right to a financial supplement that is recognized when the pension is finally accessed. In this case, the General Social Security Law establishes that, if upon reaching the ordinary age the required minimum contribution period has already been met, the interested party may choose between several incentive formulas. One of them is an additional percentage of 4% for each full year of contributions between the ordinary age and the effective retirement date.
The amount of the contributory pension depends directly on the years of contributions, so whoever certifies 15 years old will be entitled to 50% of the regulatory baseand to receive the full or 100% pension it is necessary to be at least 36 years and 6 months of contributions. That is precisely why Social Security allows workers who already meet all the requirements to retire to voluntarily prolong their working life, increasing the future pension through the supplement for delayed retirement, regulated in article 210.2 of the General Law of Social Security.
Between 4,800 and 13,500 euros at a time
The worker is free to choose how he receives the incentive. The first option is a permanent increase of 4% on the monthly pension for each full year that you extend your working life beyond the ordinary age. It must be taken into account that from April 1, 2025, periods of between six and twelve months add an additional 2% from the second year of delay, a novelty that was introduced by the Royal Decree-law 11/2024.
To understand this, let’s take an example in which a worker with a pension of 1,500 euros per month who delays his retirement for two full years would see his benefit increased by 120 euros per month for life, since the accumulated 8% is applied every month for the rest of his life. The second option is to collect a lump sum amount at the time of retirement, without reducing the pension. As detailed by Social Security:
“The worker will receive, each year after retiring, an amount that can range between 4,800 and 13,500 euros depending on the years delayed,” they explain from Social Security. The exact amount depends on the pension section recognized, that is, the higher the pension, the greater the amount of the single payment per year deferred.
A mix of both, another possibility
Workers who do not want to opt for a single modality can combine both options: an additional percentage of 4% on the pension and a flat-rate amount for each full year of contributions between the ordinary age and the effective retirement date.
In this case, the single payment is equivalent to half the amount that would correspond if the flat-rate incentive had been chosen exclusively. Furthermore, when the delay reaches eleven years or more, this payment is limited to the equivalent of five years, while the remaining years only generate the 4% increase.
Since April 1, 2025, these incentives are compatible with active retirement, which allows you to collect 50% of your pension while continuing to work and, upon permanent retirement, apply the accumulated delay supplement. Those who access partial, flexible retirement or in a situation similar to discharge are excluded.
To access this supplement, it is necessary to have reached the ordinary retirement age and have the minimum contribution period required for the contributory pension, which is generally 15 years.
The supplement is not applied automatically, but must be chosen when applying for retirement. The worker can choose between the 4% increase, the single payment or a mixed formula, so not all those who delay their retirement will see their monthly pension increased.
Practical example of how the pension increases if retirement is delayed
To understand it better, a simple example can be given. A worker with an initial pension of 1,500 euros per month who decides to delay his retirement for one year and chooses the additional percentage modality will begin to collect 1,560 euros per month. If you delay retirement for two years, the pension would rise to 1,620 euros per month, by applying an extra 8%.
Furthermore, if after those two full years you extend your working life for another six months, you could add an additional 2%, according to the regulations in force since April 2025. In that case, the total improvement would be 10% on the initial pension.
In short, the delay has become a way for those who want to continue working beyond the ordinary age and improve their future pension. The key is that the 4% per year increase exists, but it is not automatic for everyone: you must meet the legal requirements and expressly choose this modality when requesting retirement.
