ACCT 001 Lecture Notes - Lecture 24: Cost Driver, Break Even, Weighted Arithmetic Mean
Document Summary
That range over which the assumed fixed cost relationship is valid for the normal operations of an organisation. Fixed costs per unit very inversely with activity: as unit cost changes the level of cost driver changes. Examples of fixed costs: rent per month. In total, vary proportionally with changes in activity level: remain the same on a per unit basis. Examples: meters of fabric, 5% sales commission, /hour wage rate. Cost behaviour is defined with respect to a single, specific cost object/ driver. Some fixed costs do not fit the fixed cost classification completely: fixed over a moderate range of activity and then, rise or fall to new levels beyond that range. Cost function: y = a1, 0
