Maly ZUS Plus Calculator 2026
Enter your income for the previous year — the calculator returns the contribution base and monthly ZUS contributions under Maly ZUS Plus.
How Maly ZUS Plus works
Base = 50% × (annual income / 12), min. 30% of the minimum wage (2026: 1441.80 PLN), max. 60% of the forecast average wage (2026: 60% × 9420 = 5652 PLN). The contribution rates are the same as for full ZUS.
Example: previous-year income 60,000 PLN
Base = 60,000 / 12 × 50% = 2500 PLN. Total social contributions ≈ 820 PLN/month + health ≈ 450 PLN.
