The formulas to calculate the rate, volume, and mix impacts are:
Rate Impact=(Current Price−Previous Price)×Previous Volume×Previous Mix
Volume Impact=(Current Volume−Previous Volume)×Previous Price×Previous Mix
Mix Impact=(Current Mix−Previous Mix)×Previous Price×Previous Volume
Let's say the current price is $10, the previous price is $8, the current volume is 1500 units, the previous volume is 1000 units, the current mix is 0.6, and the previous mix is 0.5. Using the formulas:
Rate Impact=(10−8)×1000×0.5=1000
Volume Impact=(1500−1000)×8×0.5=2000
Mix Impact=(0.6−0.5)×8×1000=800
So, the rate impact is $1000, the volume impact is $2000, and the mix impact is $800.
Rate Volume Mix (RVM) analysis is a method used to break down the changes in revenue or profit into three components: rate (price), volume, and mix. It helps businesses understand the impact of each factor on their financial performance.
