Variance Analysis Flashcards
Materials price variance =
AQ(AP-SP)
Materials price variance is based on
amount of materials used in production
Materials quantity variance =
(AQ-SQ)SP
Favourable materials quantity variance
AQ < SQ
Fault of variance goes to
decision maker
Labour efficiency variance
(AH-SH)SR

Materials variance includes
Price and Usage
Labour variance includes
Rate, Direct, Efficiency
Labour rate variance uses
Hours x rate
Materials price variance uses
Input quantity x cost/unit
Materials usage variance uses
Output quantity x material quantity needed/unit -> variance x cost/unit
Direct labour variance uses
output quantity x hours required/unit x rate
Labour efficiency variance uses
actual output x hours -> hours variance x rate
