Factory Overhead Absorption Methods/Methods for FOH Application

1. Direct Material Cost Basis

Direct material cost basis = (Estimated FOH for the period / Estimated D.M. cost) x 100

2. D.L. Cost Basis

D.L. Hours Basis = (Estimated FOH for the period / Estimated D.L. Cost) x 100

3. D.L. Hours Basis

(Estimated FOH for the period / Estimated D.L. hours) = Per D.L. hour

4. Machine Hours Basis

(Estimated FOH for the period / Estimated machine hours) = Per machine hours

5. Prime Cost Basis

= (Estimated FOH for the period / Estimated prime cost) x 100

6. Conversion Cost Basis

= (Estimated FOH for the period / Estimated conversion cost) x 100

7. Units of Production Basis

= (Estimated FOH for the period / Estimated No. of units) x 100

Factory Overhead Variance Formulas

1. FOH Applied Rate/Burden Rate

= Estimated FOH for normal volume / Normal volume

2. Applied FOH for Capacity Attained/Actual Capacity

= Capacity attained x FOH applied rate

3. Variable Cost Rate/V.C.R.

= Estimated variable cost for normal volume / Normal volume

4. Variable Cost for Capacity Attained

= Capacity attained x Variable cost rate

5. Spending variance/Budget/Expense variance

= Actual FOH - Budgeted allowance

6. Capacity Variance/Volume Variance/Idle Capacity Variance

= Applied FOH for capacity attained - Budgeted allowance

7. Budgeted Allowance

= Fixed cost + Variable cost for capacity attained

8. Capacity Attained/Actual Capacity/Actual Output

= Applied FOH for capacity attained / FOH applied rate

9. Normal Volume/Standard Activity Level

= Fixed cost / Fixed cost rate

10. Over Applied/Under Applied FOH

= Actual FOH - Applied FOH for actual output

11. Variable Cost Rate (For Low & High Point Method)

= Difference in budgeted FOH / Difference in activity level
