Q

What are the steps of the weighted average contribution method?

A
  1. Calc weighted average contribution for products
  2. Deduct from standard contribution per unit for each product
  3. Difference = ans, shows diff between contribution generated and average contribution

16
Q

How is total variance split?

A
  • Planning
  • Operational
17
Q

What are planning variances?

A
  • Compares revised budget and original
  • Deemed to be uncontrollable
  • Management should not be held accountable
18
Q

When is a planning variance favourable?

A

Revised standard cost < original standard cost

19
Q

When is a planning variance adverse?

A

Revised standard cost > original standard cost

20
Q

Why are planning variances uncontrollable?

A

Original standard was not reflective of attainable standard

21
Q

What are operational variances?

A
  • Compares actual results with revised budget
  • Deemed controllable
  • Management held responsible
22
Q

What are some good reasons for a change in the original standard cost?

A
  • Change in main material
  • Unexpected increase in material price
  • Change in working methods
  • Unexpected change in pay rate
