Investopedia explains 'Semi-Variable Cost'
This type of cost is variable in the sense that greater levels of production increase total cost. If no production occurs, then a fixed cost is still incurred.
Labor costs in a factory are semi-variable. The fixed portion is the wage paid to workers for their regular hours. The variable portion is the overtime pay they receive when they exceed their regular hours.
