Unfavorable variances are uncovered through a process called variance analysis. This involves comparing two figures: the actual result and the planned (or standard) result. The difference between these two figures is the variance. If that difference shows your business spent more than planned or earned less than planned, it's unfavorable.
Let's break down how this works in practice. Suppose you've set a budget for producing 1,000 units of your product. You've estimated that each unit will require 2 pounds of raw material at $5 per pound. So, your standard cost for materials per unit is
0. If, in reality, you used 2.2 pounds of material per unit or the material cost increased to $5.50 per pound, you'd end up with an unfavorable materials variance. This could be due to inefficient production (using more material) or unexpected price increases from suppliers.
Similarly, for sales, if you budgeted to sell 500 units at $20 each, for a total revenue of
0,000. If you only sold 450 units at $20 each, your actual revenue would be $9,000. That
,000 difference (
0,000 budgeted - $9,000 actual) is an unfavorable sales volume variance. You didn't sell as many units as planned. Or, if you sold 500 units but had to offer a discount, dropping the price to
8 per unit, your actual revenue would be $9,000, creating an unfavorable sales price variance. The mechanics involve straightforward subtraction, but the real work begins when you investigate why these variances occurred.
