Fixed production overhead variances
The total fixed production variance is an attempt to explain the under- or over-absorbed fixed production overhead.
Remember that overhead absorption rate = | Budgeted fixed production overhead |
Budgeted level of activity |
If either the numerator or the denominator or both are incorrect then we will have under- or over-absorbed production overhead.
- If actual expenditure ± budgeted expenditure (numerator incorrect) » expenditure variance
- If actual production / hours of activity » budgeted production / hours of activity (denominator incorrect) » volume variance.
- The workforce may have been working at a more or less efficient rate than standard to produce a given output » volume efficiency variance (similar to the variable production overhead efficiency variance).
- Regardless of the level of efficiency, the total number of hours worked could have been more or less than was originally budgeted (employees may have worked a lot of overtime or there may have been a strike and so actual hours worked were less than budgeted) » volume capacity variance.
