Given:
Actual Production 6,000 units @ 1.5 standard hours per unit.
Budgeted hours: 10,000
Fixed overhead cost per unit is $0.50 per hour.
6000 units * 1.5 std. hrs/unit = 9,000 hours
Actual hours: 9,000 hours * $0.50 per hour = $4,500
Budgeted hours: 10,000 hours * $0.50 per hour = $5,000
Fixed Factory Overhead Volume Variance = $5,000 - $4,500 = $500 UNFAVORABLE.
It is unfavorable because the production is inefficient. It is more favorable if the produced units are higher than 6,000 units and the actual hours of production are more than the budgeted hours of production.
