#### How to Solve Variance Analysis Questions

## CPA Exam Prep: A Deeper Look At Variance Analysis Formulas

Mastering multi-step word problems is one key to scoring high on the CPA Exam. Not only will competence with these questions boost your confidence, but also it will speed up your calculations, allowing you to allot time to other areas of the exam.

### Summary of Variance Formulas

### Two keys to solving variance problems are:

- Find clue words within the question to indicate which operation to do and which values to use, and
- Make sure that all values are in the same denomination, such as cost per pound or hours per widget.

#### Practice Question

Carson, Inc., a manufacturer of garden tools, uses variance analysis to measure the efficiency of manufacturing overhead. Information for the manufacture of shovels for the month of April can be found below:

Actual | Budgeted | |

Shovels manufactured | 7,000 | 7,500 |

Variable OH costs | $2,000 | $0.60/DL hour |

Fixed overhead costs | $12,000 | $11,250 |

Fixed OH per unit | $1.25 per unit ($11,250/7,500 units) | |

Direct labor hours | 3,250 | 0.4 hour/shovel |

*

*Key Words: marked above in bold & italics*### What is the variable overhead efficiency variance?

**VOH efficiency variance**: efficiency compares what *was used* to what *was budgeted to be used*.

#### (AQ – SQ) x SP

What **quantity** should be used in calculations: shovels or hours? Variable overhead costs (VOH) in this practice question are budgeted based upon direct labor (DL) hours, so the AQ and SQ must be hours.

[(**Actual** DL hours for 7,000 shovels) – (**budgeted** hours for 7,000 shovels)] x budgeted rate for VOH =

[3,250 – (7,000 x .4 hour)] x $0.60 =

(3,250 – 2,800) x $0.60 = **$270 variance**

Because an extra 450 hours were used above what was budgeted to be used, this is an **Unfavorable** variance.
