# Fixed and Variable Costs

Costs can be classified into two categories, fixed and variable costs. These costs behave differently based on the level of sales volumes. Suppose we are running a restaurant and have identified certain costs along with the number of annual units sold of 1000.

Item: Raw Materials (cost for hamburgers)
Total Annual Cost: 650
Item: Building Rent
Total Annual Cost: 9000

Identify which cost item above is fixed and variable and why? What is the cost per unit of each? Suppose we increased our sales volume to 6000 units and then to 8000 units the following year (and are still within the relevant range), what would be the total annual cost and unit cost of fixed and variable costs?

...e is rent. You have to pay the same rent regardless of the number of burgers sold.

If there are 1,000 units sold, then divide each cost by 1,000.
Variable Cost (Hamburgers) - \$650 / 1,000 units = \$0.65 / unit
Fixed Cost (Rent) - \$9000 / 1,000 units - \$9 / unit
Total Cost / Unit - (\$650 + \$9000) / 1000 = \$9.65 / unit

If the sales volume increases to 6,000 units, ...
