Social Benefit for Inclusion (PSI) Calculator

How much Social Benefit for Inclusion (PSI) could you receive? This calculator estimates the monthly PSI of a person with a disability (incapacidade of 80% or more) by adding the fixed base component to the complement, which is the difference between a threshold that grows with the household and the income the household already has.

Pick the beneficiary’s age, enter the other adults and minors in the household and the household’s monthly income (excluding the PSI itself). Assumes an incapacidade of 80% or more (fixed base component) and a single beneficiary in the household. 2026 mainland figures.

Educational estimate, not advice. It computes the base component (incapacidade of 80% or more) plus the complement; it does not decide entitlement, apply the means-tested base for 60-79%, the +75% complement uplift for multiple beneficiaries or Social Security’s exact income-counting rules.

What the PSI is and who can claim it

The Prestação Social para a Inclusão (PSI), or Social Benefit for Inclusion, is a monthly benefit from Portugal’s Social Security for people with a disability and an incapacidade of 60% or more. It has two cash parts: the base component, which offsets the general extra costs of disability, and the complement, which fights poverty and goes to those on low incomes. This calculator estimates both, assuming the person meets the access conditions.

How it is calculated

For someone with an incapacidade of 80% or more, the base component is a fixed amount, independent of income: €333.64 a month for adults (18+) and €166.82 for under-18s (plus 35% in a single-parent household). The complement works like the RSI: a threshold is computed (€670 × the household scale, where the holder counts 1, each other adult 0.7 and each minor 0.5) and the household’s reference income is subtracted. Because the base component itself counts as income, the calculator adds it to the income you enter. The complement is what is left, up to a maximum of €670.

The 2026 figures

In 2026 the base component reference value is €333.64 a month (€4,003.68 a year) and the complement is €670 a month (€8,040 a year), set by Portaria no. 58-A/2026/1 and updated with the Social Support Index (IAS). The complement equivalence scale (1 / 0.7 / 0.5) is fixed in the PSI regime. The figures are for mainland Portugal.

Worked example

An adult with an incapacidade of 80% or more, alone in the household and with no other income: the base component is €333.64. The complement threshold is €670 × 1 = €670; because the base counts as income, the complement is €670 − €333.64 = €336.36. The total PSI is €333.64 + €336.36 = €670 a month. If the household already had €200 of income, the complement would fall to €670 − (€200 + €333.64) = €136.36 and the total PSI would be €470 a month.

Frequently asked questions

What is the Social Benefit for Inclusion (PSI)?
It is a monthly benefit from Portugal’s Social Security for people with a disability and an incapacidade of 60% or more. It pairs a base component, which offsets the general extra costs of disability, with a complement for those on low incomes. It replaced older benefits such as the lifelong monthly allowance.
What is the PSI amount in 2026?
The base component is €333.64 a month for adults (18+) and €166.82 for under-18s, set by Portaria no. 58-A/2026/1. The complement has a maximum of €670 a month and is granted under a means test. The total PSI received is the sum of the two parts.
How is the PSI complement calculated?
A threshold is computed as €670 times the household scale (1 for the holder, 0.7 per other adult, 0.5 per minor) and the household’s reference income is subtracted. Because the base component counts as income, it is added to the income. The complement is the difference, up to a maximum of €670; if income reaches the threshold, there is no complement.
Does income affect the base component?
For an incapacidade of 80% or more, no: the €333.64 base component is guaranteed regardless of income. For an incapacidade between 60% and 79% the base component is reduced according to income, under specific rules this calculator does not apply (it assumes 80% or more).
Which income counts for the complement?
The reference income of the whole household counts: work (89% for the holder), pensions, capital and property income and the base component itself. Some benefits are excluded (such as the RSI, the old-age solidarity supplement or social subsidies). Social Security applies its own rules, so the real amount may differ from this estimate.
Does this calculator decide whether I qualify for the PSI?
No. It only estimates the amount assuming an incapacidade of 80% or more, a single beneficiary in the household and that the access conditions are met. The decision on entitlement, the certification of the disability, the exact counting of income and the means test are all up to Social Security.
