How overtime pay is calculated
The calculator adds the overtime supplement on top of the ordinary hourly rate for those hours:
Overtime pay = Hourly rate × Number of hours × (1 + Supplement ÷ 100)
If you work 8 overtime hours at an hourly rate of 280 kr with a 50 % supplement, you get 280 × 8 × 1.5 = 3,360 kr total for those hours.
Note: Overtime supplement rules can vary between collective agreements and employment contracts. Norway's Working Environment Act requires at least a 40 % supplement, but many agreements give a higher rate. Check your own agreement for the correct rate — this calculator applies to Norwegian employment law only.
