Material Cost Variances
Study Tip & Formula Logic
Memorization Hack: "Hold the other guy constant." When finding Price variance, hold the Actual Quantity constant. When finding Usage variance, hold the Standard Price constant.
Interpretation: Price Variance asks "Did purchasing negotiate well?" Usage variance asks "Did production waste materials?"
Price Var = (SP - AP) × AQ | Usage Var = (SQ - AQ) × SP
Material A
Material B (For Mix/Yield)
Labor Cost Variances
Study Tip & Formula Logic
Memorization Hack: Labor is just Material in disguise! Swap "Quantity" for "Hours" and "Price" for "Rate".
Interpretation: Idle Time is always Adverse because paying workers to do nothing is a pure loss. Always deduct Idle Time from Actual Hours Paid to get Actual Hours Worked before calculating Efficiency!
Rate Var = (SR - AR) × Actual Hours Paid
Skilled Labor
Unskilled Labor
Fixed Overhead Variances
Study Tip & Formula Logic
Memorization Hack: "Fixed" means it doesn't change with output. Therefore, variances are all about under or over Absorption (Recovery).
Interpretation: The Calendar Variance only exists if the factory worked more or fewer days than budgeted. Capacity Variance checks if we utilized our planned factory hours.
Recovered FOH = Actual Output × Standard Rate per Unit
Budgeted Data (The Plan)
Actual Data (The Reality)
Sales Value Variances
Study Tip & Formula Logic
Memorization Hack: Reverse the Cost logic! For sales, Actual exceeding Standard is a GOOD thing. Always calculate as: (Actual - Standard).
Interpretation: Mix Variance tells us if we sold a higher proportion of our expensive products compared to cheaper ones. Volume Variance just looks at pure unit sales.
Sales Price Var = (AP - SP) × AQ | Sales Vol Var = (AQ - BQ) × SP
Product X
Product Y
Variable Overhead Variances
Study Tip & Formula Logic
Memorization Hack: Variable Overhead behaves identically to Labor. Just replace Rate with VOH Rate.
VOH Expenditure = (Std Rate × Actual Hrs) - Actual VOH
