- 2. Excess income
- Income − parents’ needs
- 3. Offset
- 45% of the excess earned income (other income: 100%)
- 4. Child supplement
- Maximum amount (€297 per child) − offset
- Parents’ net income
- €1,500
- Parents’ needs (standard need €563 + supplement €67.56 + 77% housing share €577.50)
- €1,208.06
- Excess income
- €291.94
- Offset against the child supplement (45%)
- - €131.37
- Child supplement (maximum amount €297 − offset)
