Child support calculator for a child — estimated amount

Estimate child support based on net income and number of children.

How does the calculator work?

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.

Rates and thresholds (indicative)

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%

Conditions and exceptions

• The final amount is set only by the court (Art. 135 § 1).
• No statutory minimum — there is no fixed minimum alimenty; it depends on needs and capacity.
• Alimenty fund — benefit when enforcement is ineffective and statutory criteria are met.
• Art. 135 § 3: the scope of alimenty is not affected by fund benefits, social assistance, 500+, childcare benefit etc.

Examples

• One child, income 5000 PLN net → indicative range calculated from percentage bands. • Two children, income 6000 PLN → indicative range calculated from percentage bands. • Three children, income 8000 PLN → indicative range calculated from percentage bands. The final amount is set by the court after examining the child's needs and the obligor's capacity.

FAQ

On what basis is the amount of alimenty set?: Art. 135 § 1: the scope of maintenance depends on the justified needs of the entitled person (e.g. the child) and the obligor's earning and asset capacity. The Act does not set fixed amounts — the court sets the final amount.
Where do the percentage ranges (15–20%, 8–12%) come from?: From court practice. Courts often use about 15–20% of income for one child and about 8–12% for each further child. The calculator reflects these ranges for estimation only.
Can the court award alimenty higher or lower than the calculator?: Yes. The court examines the child's needs and the parent's capacity. The result may be outside the calculator range.
What is the alimenty fund and when can you use it?: Benefit from the fund is due when enforcement of alimenty fails and statutory criteria are met. Details: gov.pl.
Until when does a parent pay alimenty for a child?: Art. 133 § 1: until the child is able to support themselves. Age is not decisive — education and real self‑support are key.
Can alimenty be reduced or increased?: Yes. If circumstances change you can apply to the court to change the order. A change requires proceedings.
Do benefits from the alimenty fund count towards the child's needs?: No. Art. 135 § 3: the scope of alimenty is not affected by fund benefits, social assistance, 500+ etc. The court sets alimenty based on the obligor's capacity and the entitled person's needs.
