Variance analysis is a crucial tool for evaluating the financial performance of an organization by comparing actual costs with budgeted standards. The assignment content highlights two types of variance: Cost Variance Analysis, which includes direct material, direct labor, and overhead variances; and Sales Variance Analysis, which examines the difference between cost of goods sold (COGS) and sales. Overhead fixed price variance and overhead variable cost variance are specific examples of cost variances, while sales value variance and sales margin are key components of sales variances. The analysis aims to identify deviations from standards, allowing for timely corrective action and improving cost control. The partial plan and single plan methods are discussed as approaches for analyzing and valuing inventory at standard costs.
