The lump sum (basic amount for calculating the activity premium) is equal to €638.28.

The lump sums vary depending on whether you live alone or in couple and depending on the number of children or people at your load :

The amount of the activity bonus shall be calculated taking into account:

1. on the one hand, a lump sum which varies according to the composition of the household and the number of dependent children to which must be added 59.85% the amount of the household's professional income. This amount may be increased taking into account the professional income of each worker. This increase is called enhancement.
2. on the other hand, the resources taken into account of the household.

The calculation formula is as follows:

Amount of the activity bonus = (lump sum possibly increased + 59.85% professional income + individual bonuses) - the resources taken into account by the household.

Can the amount of the activity bonus be increased?

The amount of the premium may be increased if you are in isolation and depending on the composition of your home.

This increase is called markup.

Increase according to the composition of the household

The rate of this increase shall be:

• 50% for the 1^re extra person
• 30% per additional person
• 40% per additional person beyond 3^e person if your household has more than 2 children or dependents under 25 years of age.

Isolation surcharge

If you are a single parent, i.e. single, divorced, separated or widowed with dependent or pregnant children, the lump sum is increased.

This increased lump sum shall be granted from the month in which one of the following events occurs:

• Declaration of pregnancy
• Declaration of birth of a child
• Declaration of care of a child
• Declaration of separation
• Declaration of widowhood.

The increased lump sum can be granted for 12 months, continuous or discontinuous, during a period of 18 months following the event.

This amount varies depending on the number of dependent children.

If your youngest dependent child is under 3 years of age, the increased lump sum is granted to you until the age of 3.

The increased lump sum shall be equal to 128.412% the basic lump sum.

Adds to it 42.804% the basic lump sum for each child.

What is the individual bonus?

Each member of the household with a professional activity can obtain a bonus that varies according to his monthly professional income (average over the last 3 months).

This bonus is due if the average monthly salary is higher than €726.29.

The amount of the subsidy is increasing according to income.

It ranges between a few euros (€26.29 for a monthly income of €700, for example) and €240.63 if the average salary is more than €1,698.78.

Beyond that, the amount of the subsidy remains constant.
