Fixed-overhead variance
Fixed-overhead variance is the total difference between actual fixed manufacturing overhead incurred and the amount applied to production under absorption costing.

The waterfall chart starts at applied overhead of €110,000 and steps upward through two adverse variances — a volume variance of +€10,000 and a spending variance of +€2,000 — to reach actual overhead of €122,000. The chart makes clear that the total adverse gap of €12,000 combines two distinct causes: spending more than the budgeted fixed overhead (spending variance) and producing fewer units than the denominator volume used to set the absorption rate (volume variance).
The formula
Variables
- Fixed manufacturing overhead actually incurred (€)
- Planned fixed manufacturing overhead for the period (€)
Adverse if actual exceeds budget; measures whether fixed costs were kept within the plan
Variables
- Planned fixed manufacturing overhead (€)
- Fixed overhead rate per unit (€ per unit)
- Actual production volume
Adverse when actual output falls short of budgeted volume; reflects the cost of under-utilised capacity
