## How do I calculate the variable cost?

`To calculate variable costs, you should add up all of the physical materials needed for a project. This can be done using a spreadsheet program such as Sourcetable. The formula for calculating variable costs is `Total Variable Cost = Quantity * Unit Cost`. For example, if you need 10 units of material at a cost of \$5 each, your total variable cost would be \$50.`

## How much is the variable cost per unit?

`The variable cost per unit is the sum of variable costs.`

## How do variable costs affect output?

## What is the importance of variable costs?
