For self-employed workers, meeting the contribution requirements is key to ensuring 100% of their pension upon retirement. In 2025, those who wish to receive their full regulatory base must have accumulated at least 36 and a half years of contributions. In 2027, this minimum will increase to 37 years. If this contribution period is not reached, the pension will be calculated by applying a reduction percentage based on the years of contributions.  

For example:  

• Regulatory base: A self-employed person with a base of €1,435.3 per month would receive 100% (€1,435.3) only if they meet the contribution requirements.
• Reduction by years: With only 15 years of contributions, 50% of the regulatory base is considered, resulting in a pension of €717.
• Gradual increase: From year 16, each additional month of contributions between months 1 and 49 increases the base by 0.21%. For example, with 16 years of contributions, the pension would be calculated on 52.52% of the base, resulting in €753.3.

This gradual system continues until reaching 100% of the pension after 36 and a half years of contributions. Therefore, it is essential that self-employed people plan their retirement and contribute what is necessary to ensure maximum coverage. 

Conclusion:

Not reaching the appropriate contribution period significantly reduces the amount of the pension. Knowing these details allows self-employed people to make informed decisions to ensure their financial well-being in retirement.
