Variance analysis quantifies the difference between actual and planned performance. It is used to maintain control over a business. Major cost variances include: 1. Direct material price and quantity variances which measure the difference between actual and standard material costs. 2. Direct labor rate and efficiency variances which compare actual labor hours and rates to standards. 3. Variable overhead spending and efficiency variances which show the difference between actual and standard variable overhead costs. 4. Fixed overhead variance compares actual fixed overhead to the budgeted amount.
