Price variance

Price variance is the actual unit cost of a purchased item, minus its standard cost, multiplied by the quantity of actual units purchased. The price variance formula is:

(Actual cost incurred - standard cost) x Actual quantity of units purchased
= Price variance

If the actual cost incurred is lower than the standard cost, this is considered a favorable price variance. If the actual cost incurred is higher than the standard cost, this is considered an unfavorable price variance. However, achieving a favorable price variance might only be achieved by purchasing goods in large quantities, which may put the business at risk of never using some of its inventory. Conversely, the purchasing department may be committed to having very little inventory on hand, and so buys materials in very small quantities, which tends to result in unfavorable price variances. Thus, the operational plan of a business tends to drive the types of price variances that it incurs.

The price variance concept can be applied to any type of cost. For example, there is the labor rate variance for labor costs, the purchase price variance for materials, the variable overhead spending variance for variable overhead, and the fixed overhead spending variance for fixed overhead.
