AcqNotes: Cost Variance. The high-low method computes the variable cost rate by dividing the change in the total costs by the change in the number of units of manufactured. How do I find the CPI? Then, add together the current prices of the same products. Divide the total of current prices by the old prices, then multiply the result by Finally, to find the percent change in CPI, subtract What are the main causes of variance?

Following are the possible causes of this variance: Appointing low grade workers. Inadequate training to employees. Incorrect Instructions.

Us e of sub —standard material requiring rework. Use of defective machinery and equipment. Incompetent supervision. Poor working conditions. Poor scheduling of production processes. Is variance always positive? Variance is always nonnegative, since it's the expected value of a nonnegative random variable. Moreover, any random variable that really is random not a constant will have strictly positive variance. What is variance percentage?

Definition: A percent variance is the change in an account during a period of from one period to the next expressed as a ratio. In other words, it shows the increase or decrease in an account over time as a percentage of the total account value. What does a positive variance indicate? The reason is that having less revenues than planned is not good.
