How to calculate the difference rate of property fee index

Material cost variance rate refers to the ratio of material cost variance to material planned cost, usually expressed as a percentage.

Material cost variance refers to the difference between the actual cost and the planned cost of materials. A positive number indicates the difference rate of overspending, and a negative number indicates the difference rate of savings. The calculation formula is as follows:

Material cost variance rate = (opening material cost variance+current month warehousing cost variance)/(opening raw material planned cost+current month warehousing material planned cost) × 100% In actual work, the calculation of material cost variance rate is completed by compiling a "material cost variance calculation table".

Last month's material cost variance rate = material cost variance on balance at the beginning of the month/planned material cost on balance at the beginning of the month X 100%; material cost variance on issue this month = planned material cost on issue this month x material cost variance rate.

Actual cost of materials issued this month = planned cost of materials issued this month+variance of materials issued this month = planned cost of materials issued this month+variance of materials issued this month, actual cost of materials issued this month = (planned cost of materials issued at the beginning of the month+planned cost of new materials this month-planned cost of materials issued this month) ×( 1+ variance rate of materials costs).
