Since the 2019 Social Security Reform, the INSS (Brazil’s National Social Security Institute) benefit calculation uses 100% of your contribution salaries since July 1994. It applies a 60% coefficient to the average, plus 2% for each additional year of contribution.

The Change in the Calculation Under Constitutional Amendment 103/2019

Before Constitutional Amendment 103/2019, Law 9.876/1999 required the benefit base (salário de benefício) to be calculated from the average of the highest 80% of contribution salaries since July 1994. The reform changed that formula. It now uses 100% of contribution salaries from the same starting month, with no discarding of the lowest 20%.

The change may look minor, but it has a significant impact when the insured worker had periods of low pay. Because every salary is counted, not just the highest 80%, the average tends to drop for anyone whose earnings varied over the course of a career.

How the 60% Coefficient and the Increments Work

The other major change was a fixed 60% coefficient applied to the benefit base as the starting point. For each year of contribution beyond the minimum required for retirement, 2% is added to the coefficient. The required minimums are:

• Women: 15 years (180 contributions);
• Men: 20 years (240 contributions).

For example, for a woman with 30 years of contribution: 60% + (15 extra years × 2%) = 90% of the salary average. To reach 100%, she would need 35 years of contribution (15 minimum + 20 additional years × 2% = 100%).

Women need 35 years of contribution to receive 100% of the average; men need 40 years. Anyone who retires earlier receives proportionally less.

For a man with 40 years of contribution: 60% + (20 extra years × 2%) = 100% of the salary average. In other words, men need 40 years of contribution to reach 100% of the benefit base.

What Makes Up the Benefit Base

The benefit base is the amount to which the coefficient is applied. It is the simple arithmetic average of all contribution salaries since July 1994, adjusted for inflation using the INPC (Brazil’s National Consumer Price Index). This amount is subject to the RGPS (General Social Security Regime) ceiling, which in 2026 is R$ 8.475,55.

Contribution salaries above the ceiling are capped at the ceiling for calculation purposes. Salaries below the floor (the minimum wage) are counted at the amount actually contributed. Including every salary, even months of minimum contributions, tends to pull the average down for careers with irregular earnings.

The Pension Factor: When It Still Applies

The pension factor (fator previdenciário) is a reducing mechanism that takes into account age, length of contribution and life expectancy. Constitutional Amendment 103/2019 largely emptied it of effect, but did not abolish it entirely. It remains a calculation option for retirement by length of contribution under the transition rules, for workers who still choose that route, when it works in the insured person’s favor.

In practice, the INSS calculates the benefit both with and without the pension factor and grants the higher amount. For most insured workers with a long contribution history, the simple coefficient without the factor tends to be more advantageous than the pension factor, which penalized people who retired early.

A Practical Calculation Example

Consider a concrete example: a woman, age 62, with 32 years of contribution and an average salary of R$ 3.500,00.

Calculation: 60% + (17 extra years × 2%) = 60% + 34% = 94% of R$ 3.500,00 = R$ 3.290,00 in benefits.

If the same worker had 35 years of contribution: 60% + (20 × 2%) = 100% of R$ 3.500,00 = R$ 3.500,00. In this example, each additional year of contribution adds R$ 70,00 per month, and that increase carries through the rest of her life.

How to Check the Calculation in the CNIS and Request Corrections

Verifying the benefit calculation starts with a careful review of the National Social Information Registry (CNIS), which compiles your employment records, contribution salaries and contributions as a self-employed worker. Before you file for retirement, you should check that every employment relationship is recorded, that the contribution salaries reflect what you actually earned, and that no periods are missing. Pay particular attention to 1994 through 2000, when the digitization of records still had significant gaps at many companies and in informal work.

If you find discrepancies, you can request an update to the CNIS through the Meu INSS app or in person at an INSS office. Bring your work card, pay stubs, contracts and contribution payment slips as proof of the correct amounts. In more complex situations, such as unregistered employment, contributions paid late by employers, and companies that have since closed, you may need to go to court to obtain recognition of the time and salaries. In those cases, the claim rests on witness testimony and documents from the period worked.

Another important point is choosing the right moment to apply for retirement. Because the coefficient rises 2% for each additional year of contribution, working a few more months can significantly increase your monthly benefit. On the other hand, delaying your application has an opportunity cost, because you go without payments during that time. The decision should also take into account your life expectancy, your health, your projected earnings over the coming years and any other sources of income. We recommend running personalized simulations before making a final choice.

Frequently Asked Questions

Do contributions above the ceiling increase the benefit average?

No. Contribution salaries are capped at the RGPS ceiling, both for payment of contributions and for calculating the benefit. Even if a worker earns more than the ceiling, the contribution and the amount counted toward the benefit base are limited to the ceiling in force for each month. If you earn a high income, you should consider supplementary private pension products to offset this limit.

Do periods of sickness benefits count toward the benefit base average?

The months in which the insured person received sickness benefits (auxílio-doença) are not included in the benefit base average, because there was no contribution salary in those periods. However, those periods do count as contribution time for the minimum contribution period (carência) and for the 2%-per-year coefficient increment. The effect on the average may be positive (if your salaries in those months would have been low) or neutral.

Is the calculation different for someone who retired before the reform and requests a review?

If you retired before November 2019 (when Constitutional Amendment 103/2019 took effect), your benefit was calculated under the rules in force at that time. A review of those benefits follows the law in effect when the benefit was granted. It may be based on a proven error, a period that was not counted or another specific ground. The so-called whole-life review (revisão da vida toda) (Tema 1.102 of the STF, Brazil’s Federal Supreme Court) was overturned as a general thesis. Earlier rulings, payments and procedural situations should be checked against the court’s modulation of effects.
