The high-low method is a technique for estimating the fixed and variable components of a mixed cost by analyzing data from high and low activity levels.
It is a cost estimation technique that involves selecting the highest and lowest levels of activity within a given period and using the corresponding costs associated with those activity levels to estimate fixed and variable costs.
The high-low method assumes that costs can be divided into fixed and variable components, where fixed costs remain constant regardless of the activity level, while variable costs change in proportion to the activity level.
