Ok so here’s the mnemonic from Becker, “PURE” and I have modified it a bit:
P Q P AQ(AP – SP) Price Var and VAR OH SPEND Var
U P Q SP(AQ- SQ) Usage/Qty Var
R H R AH(AR – SR) Rate Var
E R H SR(AH- SH)Efficiency Var and VAR OH EFF Var
P is Price Variance, and is also Variable OH SPENDING Var. AQ(AP – SP)
U is Usage/Quantity Variance SP(AQ – SQ)
R is Rate Variance AH(AR – SR)
E is Efficiency Variance, also is Variable OH EFF Var.
SR(AH – SH)
Notice how the letters carry over into the formula’s. This is the memory trick that I used to remember them– “PURE, QPHR, PQRH”. Lastly “ASAS” to remember the first letter for each successive formula. It is silly, but this helped me a lot. In my opinion, you definately need to work several of these problems as sometimes you have to calculate a number that goes into the formula. There are lots of problems in Wiley BEC book and cpareviewforfree
