Standard costing is a management accounting system that sets predetermined costs for products and compares them to actual costs. This method helps control expenses, facilitates budgeting, and supports pricing decisions by establishing benchmarks for materials, labor, and overhead. Variance analysis is a key component of standard costing, involving the calculation and investigation of differences between actual and standard costs. By analyzing these variances, managers can identify areas for improvement, develop corrective actions, and monitor performance across various industries.
