Advanced Variance Analysis
Factory overhead variances get more complex because overhead includes both fixed and variable components. You can analyze them using 1-way, 2-way, 3-way, or 4-way analysis depending on how detailed you want to get.
The 2-way analysis splits overhead variance into budget variance (actual vs. budgeted overhead) and volume variance (budgeted vs. applied overhead). The 4-way analysis breaks this down further into variable rate, fixed budget, variable efficiency, and fixed volume variances.
Material mix and yield variances help when you use multiple materials. Mix variance shows the cost impact of using different proportions of materials than planned. Yield variance measures whether you got the expected output from your material inputs.
Gross profit variance analysis examines why your gross profit changed from budget. It considers price factors (selling price changes), cost factors (cost changes), and volume factors (sales quantity changes). This helps identify whether profit changes came from pricing decisions, cost control, or sales performance.
Real-World Application: Focus on significant variances only - investigating every small difference wastes time. Use the "management by exception" principle to prioritize your attention.
