Actual Actual Stnd Stnd
$ QTY $ QTY
\-----------------/ \-----------------/
1. The difference between
these numbers is price/wage/
VC OH spending variances
\------------------/ \------------/
2. Difference between these numbers is
usage/ efficiency
There are only 2 variance formulas, and they answer 3 questions each. It doesn’t matter what the question is asking, if it is DM, DL, or VC OH, these 2 formulas answer the question.
Any variance question asking for price or purchasing info is the first one.
Any variance question asking for usage (DM, DL, VCOH) is the second one.
When you get a question, set up the table as shown at the top of the page. Plug in the numbers for actual dollars and QTY and Standard dollars and quantity. Then ask yourself if its price related (use the formula for 1.) or if it is usage related (use the formula for 2.).
Find difference between the numbers. Remember that you read from left to right, and that is the right way to read. If you find the numbers are increasing as you move to the right, then it’s favorable. If the numbers are increasing as you move from the left to the right, than it’s not the right way to read so it is unfavorable.
FC OH variance is totally different.
Do not try to plug FC variance into these formulas. As soon as you see the FC in the question, move over to this
Actual Budgeted OH
OH Applied
\ -------------------------------/ \-------------------------/
spending/budget variance volume variance
Spending/budget variance is the difference between actual OH and what was budgeted. Remember FC does not change the more you produce, so look for a total number on this like ‘Actual FC OH was XXX.’ And budgeted total FC will be given to you also.
Volume variance is:
Actual quantity produced * Budgeted FC OH dollars
Budgeted activity (DL HRS/Machine HRS/etc)
NOTE: if you practice this table form while doing the homework, you will start to understand the formulas Becker gives you. Don't memorize the formulas - set up the table and do it visually. There is enough to memorize on this test already.
You must get this nailed down to pass this test. Trust me on this.
