ACC 1110 Lecture Notes - Lecture 3: Scatter Plot, Linear Regression, Fixed Cost
Document Summary
This assumption allows the costs to be separated into variable or fixed cost category. A total variable cost will increase or decrease in proportion to the change in activity level. For example, when more pages of flyer are printed, the more paper will be used. However, the unit variable cost or cost per sheet of paper remains the same and does not vary as number of pages printed varies. A total fixed cost remains the same in total despite a change in activity level. For example, the storage rental remains the same regardless of how many items you placed in the storage unit. However, unit fixed cost will increase when activity level decreases. Based on the characteristics of aforementioned costs and the assumption of relevant range, most costs -- whether, mixed, variable, or fixed, can be estimated using this formula: Estimation methods: scatter graph or scattergram, high-low method, linear regression using excel.
