Presentation Transcript

You should be able to:

Distinguish between fixed costs and variable costs

Use knowledge of this distinction to deduce the break-even point for some activity

Make decisions on the use of space capacity, using knowledge of the relationship between fixed and variable costs

Make decisions about the acceptance or rejection of a contract or activity, based on knowledge of the relationship between fixed and variable costs

Cost-volume-profit analysis

Those that stay fixed (the same) when changes occur to the volume of activity

Fixed

Those that vary according to the volume of activity

Variable

The behaviour of costs

Graph of variable costs against the volume of activity

The slope of this line gives the variable cost per unit of activity
