Estimate child support based on net income and number of children.
In Poland alimenty are not set by law in fixed amounts. Art. 135 § 1 of the Family and Guardianship Code provides that the scope of maintenance depends on the justified needs of the entitled person (e.g. the child) and the earning and asset capacity of the obligor. The court sets the amount after hearing the case. This calculator shows an indicative range based on case law and does not replace the court’s assessment.
The Act does not contain an alimenty table or minimum amounts. The percentage ranges below reflect court practice — they are not statutory.
| Number of children | Indicative % of income (lower) | Indicative % of income (upper) |
|---|---|---|
| 1 | 15% | 20% |
| 2 | 23% | 32% |
| 3 | 31% | 44% |
| 4 | 39% | 56% |
| max. total | 60% | 65% |
