How Portugal's pension is calculated

The formula: reference remuneration × formation rate

The value of the old-age pension in Portugal comes from a multiplication¹:

monthly pension = reference remuneration × global formation rate

The reference remuneration is, in practice, your average monthly salary across your whole career. The global formation rate is the percentage of that salary you are entitled to, and it grows with your years of contributions. To estimate the value with your own figures, use the pension estimator.

The reference remuneration

The reference remuneration (RR) is obtained by dividing the total of your whole-career earnings by 14 × n, where n is the number of calendar years with a record of earnings, capped at 40¹.

Why 14 × n? Because over a year there are about 14 payments (12 months plus the holiday and Christmas bonuses). Dividing the career total by 14 × n therefore returns your average monthly salary. That figure (your career-average salary) is what you enter in the estimator.

One important detail: Social Security revalues older salaries by revaluation coefficients, to offset inflation over the decades. So the official reference remuneration is usually a little higher than the simple average of the nominal salaries.

The global formation rate

The formation rate depends on your years of career¹:

• Up to 20 years of career: the rate is 2% for each year, with a global minimum of 30%. With 15 years (the guarantee period) you reach exactly 30%; with 20 years, 40%.
• From 21 years: the annual rate varies between 2% and 2.3%, applied by brackets of the reference remuneration (in multiples of the IAS, which in 2026 is €537.13³):

Each portion of the remuneration is multiplied by its rate and by the years of career. The lower the remuneration, the higher the rate, a way of protecting more modest pensions. The global rate never exceeds 92%, reached with 40 years of contributions in the lowest bracket.

You must meet the guarantee period

Reaching retirement age is not enough. To be entitled to the old-age pension under this regime you generally need at least 15 calendar years with a record of earnings, the guarantee period². Those who do not meet it receive no pension by this route, but may be entitled to the social old-age pension, which is means-tested and calculated differently.

An example

Take a career-average salary of €1,500 and 40 years of contributions. As €1,500 splits across the brackets (€590.84 at 2.3%, €483.42 at 2.25% and €425.74 at 2.2%), about €33.83 of pension accrues per year of career. Over 40 years the global rate approaches 90% and the estimated monthly pension is around €1,353, or about €18,946 a year, paid over 14 payments. The pension estimator does this maths for you.

What the calculation does not include

The estimator gives a figure by the official formula, but some factors are left out, as they depend on your specific case:

• the minimum old-age pension, which can raise the value of a low pension;
• the exact revaluation of older salaries by coefficients;
• the pre-2002 regime and the pro-rata applicable to those who started contributing before then;
• the early-retirement cuts (sustainability factor and penalty), which apply to those who retire before the normal age, see the retirement age calculator;
• income tax (IRS) on the pension.
