Abono de Família Calculator 2026: Portugal Child Benefit

The abono de família is a monthly benefit paid by Social Security for each child or young person in the household. How much you get depends on the family’s income bracket (escalão) and the child’s age. Enter your household annual income, how many children are entitled, and the child’s age to estimate the bracket and the 2026 monthly amount.

Use the gross annual income of the whole household. The reference income divides it by the number of entitled children, plus one.

The reference income sets the bracket

Social Security does not look only at total income: it divides it by the number of entitled children and young people, plus one. That “reference income” is then compared with multiples of the IAS (the social-support index, €537.13 in 2026) times 14. The lower the reference income, the higher the bracket, and the larger the benefit. The more entitled children you have, the lower the reference income.

Five brackets: the 5th gives no benefit

There are five brackets. The 1st runs up to 0.5 × IAS × 14 of reference income; the 2nd up to 1 × IAS × 14; the 3rd up to 1.7 × IAS × 14; the 4th up to 2.5 × IAS × 14. Above that, the household falls into the 5th bracket and receives no abono. In 2026 the annual limits are €3,759.91, €7,519.82, €12,783.69 and €18,799.55 of reference income.

The amount falls with age; single-parent families get 50% more

Within each bracket, the amount is highest for babies (up to 36 months) and steps down after 36 and 72 months. In the 1st bracket a child up to 36 months gets €190.98/month; from 36 to 72 months, €75.13. Single-parent families (one responsible adult) get a 50% increase on the benefit. This calculator shows the amount for one child of the age you choose.

What the calculator assumes (and does not cover)

It works out the bracket and the amount for one child of the chosen age, from the household annual income and the number of entitled children. It uses the 2026 IAS (€537.13). It does not include the extra increase for a 2nd or 3rd child under 36 months, the pre-natal benefit, or the difference between a new claim (assessed on the previous year’s income and that year’s IAS) and a reassessment. It is an educational estimate of the bracket and order of magnitude. The official figure is set by Segurança Social Direta.

Worked example

Take a household with €18,000 annual income and one child aged 2 (up to 36 months). The reference income is €18,000 ÷ (1 + 1) = €9,000. Since €9,000 is above €7,519.82 and below €12,783.69, the family is in the 3rd bracket. For a child up to 36 months, the 3rd bracket pays €132.07/month, about €1,585 a year. For a single-parent family, add 50%: €198.11/month. With two entitled children the reference income would fall to €6,000 (÷ 3) and the family would move up to the 2nd bracket.

Frequently asked questions

How do I know which abono de família bracket I am in?
Add up the whole household’s annual income and divide by the number of entitled children and young people, plus one. The result (the “reference income”) is compared with multiples of IAS × 14. In 2026, up to €3,759.91 is the 1st bracket; up to €7,519.82, the 2nd; up to €12,783.69, the 3rd; up to €18,799.55, the 4th; above that, the 5th bracket, which gets no benefit.
How much is the abono de família in 2026?
It depends on the bracket and age. For a child up to 36 months it ranges from €190.98 (1st bracket) to €88.43 (4th bracket) per month. From 36 months the amounts fall: €75.13 in the first two brackets, and less in the others. Single-parent families get 50% more.
What is the single-parent (monoparental) increase?
It is a 50% top-up on the abono de família for households with a single adult responsible for the child. It applies up to the 4th bracket. Tick the “single-parent family” option in the calculator to see its effect on the monthly amount.
Why does having more children raise the benefit per child?
Because the reference income divides total income by the number of entitled children plus one. With more children that figure drops, which can place the family in a higher bracket, and therefore a larger benefit for each child.
Does the child’s age change the amount?
Yes. The benefit is highest up to 36 months (to support the early years) and steps down after that, with a further step at 72 months. In the 4th bracket there is no benefit after 72 months. Choose the age band in the calculator to see the right amount.
Are the figures exact?
The €537.13 IAS, the bracket multiples (0.5 / 1 / 1.7 / 2.5 × IAS × 14), the amounts table and the 50% increase are official for 2026. The result is an educational estimate: it does not include the extra increase for a 2nd/3rd child under 36 months, the pre-natal benefit, or the difference between a new claim and a reassessment. Always confirm on Segurança Social Direta.
