It is a technique for determining both variable cost per unit and total fixed cost separately from the total cost. The main assumption under this method is that the variable cost per unit and fixed cost for all the levels is the same. It only considers the highest and lowest levels of activity for calculating variable and fixed costs. High low method calculator is based on the same assumption. Under this method, first of all, we calculate variable costs per unit. And the next step is to calculate the fixed cost with the help of the variable cost per unit calculated in the first step.

This method will help in determining the total cost at different levels using a linear equation:

y = a + (b*x)

Where y = total cost for x number of units

a = fixed cost

b = variable cost per unit

x = number of units under calculation

The formula to calculate variable cost per unit and fixed cost using the high-low method is as follows:

**Variable Cost Per Unit**:

(y2 – y1)/(x2 – x1)

Where y2 = cost at the highest production level

y1 = cost at the lowest production level

x2 = total units at the highest production level

x1 = total units at the lowest production level

This will provide the result of variable cost per unit. Let us denote this variable cost per unit by ‘**b**.’

**Fixed Cost**:

After calculating variable cost per unit, put this value in the formula of fixed cost to obtain fixed cost.

**Fixed Cost** = y2 – (b*x2)

## High Low Method Calculator

## How to Calculate using High Low Method Calculator?

Simply insert the following data into the high-low method calculator for an instant calculation.

**Cost at Highest Production Level** – Insert the total cost of the highest level into the calculator. Note this is the total cost, variable, and all fixed costs.

**Cost at Lowest Production Level** – Insert the total cost of the lowest level into the calculator.

**Total Units at Highest Production Level** – Input the total number of units manufactured at the highest level.

**Total Units at Lowest Production Level** – Input the total number of units manufactured at the lowest level.
