Overtime Pay Calculator 2026

Polish labour law (Kodeks pracy) requires employers to pay an overtime supplement on top of the regular hourly rate: 50% for regular weekday overtime and 100% for night, Sunday and public holiday work. This calculator derives the hourly rate from the base monthly salary and computes total overtime pay including the statutory supplement.

How the overtime pay calculator works

Step 1: Hourly rate = base monthly salary / monthly working hours (default 168 h). Step 2: At 50% supplement — overtime pay = hourly rate × 1.5 × hours (supplement = rate × 0.5 × hours). Step 3: At 100% supplement (dobowe_100 or swiateczne_100) — overtime pay = hourly rate × 2 × hours. Monthly working hours vary. Enter the actual figure for the month instead of the default 168 h.

Example: 5,000 PLN salary / 168 h, 10 hours at 50%

Base salary 5,000 PLN, working time 168 h: hourly rate = 29.76 PLN/h. 10 overtime hours at 50%: pay = 29.76 × 1.5 × 10 = ~446 PLN (supplement = ~149 PLN). At 100% (night/holiday): 29.76 × 2 × 10 = ~595 PLN.

Frequently asked questions about overtime
