Cost Variance Analysis Calculator for CA and UGC NET Aspirants
Cost variance analysis is essential for understanding the differences between budgeted and actual costs in a business. This knowledge is particularly crucial for students preparing for CA (Chartered Accountancy) exams and UGC NET in Commerce. Cost variances help businesses identify areas where spending deviates from the plan, enabling managers to make strategic decisions.
Our Cost Variance Calculator is designed to simplify these calculations. The calculator is organized by types of variances, covering Material, Labour, Variable Overhead, and Fixed Overhead Cost Variances. This tool offers step-by-step answers, categorizing results as either Favourable or Adverse based on positive or negative variance values.
Each calculation type features two levels of dropdowns to enable selection among relevant options. The calculator automatically provides additional input fields and guidelines based on the selection, offering a smooth experience tailored to each variance type.
NOTE: Attention required. This calculator still in development stage, your feedback is valuable:

How to Use This Calculator
Step 1: Choose a Cost Category
Select from Material Cost Variances, Labour Cost Variances, Variable Overhead Cost Variances, or Fixed Overhead Cost Variances in the first dropdown menu.
Step 2: Select a Specific Type
After choosing a main category, an additional dropdown will appear with options like Single Material Input or Mix of Raw Materials. This second selection will tailor the input fields for the specific variance calculation.
Step 3: Enter the Required Inputs
Each input field (such as Standard Quantity (SQ) or Actual Quantity (AQ)) is defined based on industry-standard formulas. For ease of use, input field labels are consistent with textbook terminologies used in CA and UGC NET exams.
Step 4: Review the Answer.
The final answer is displayed in bold, with favorable outcomes in green and adverse outcomes in red.A. Material Cost Variances
Single Material Input
- Material Cost Variance: (SQ × SP) - (AQ × AP)
- Material Price Variance: (AQ × SP) - (AQ × AP)
- Material Usage Variance: (SQ × SP) - (AQ × SP)
Mix of Raw Materials
- Material Mix Variance: (RAQ × SP) - (AQ × SP)
- Material Yield Variance: (SQ × SP) - (RAQ × SP)
Note: RAQ (Revised Actual Quantity) is added to account for input adjustments in a mixed material scenario.
B. Labour Cost Variances
Single Labour Input
- Labour Cost Variance: (SH × SR) - (AH × AR)
- Labour Rate Variance: (AH × SR) - (AH × AR)
- Labour Efficiency Variance: (SH × SR) - (AH × SR)
Mix of Labour Input
- Labour Mix Variance (or Labour Gang Variance): (RAH × SR) - (AH × SR)
- Labour Productivity Variance: (SH × SR) - (RAH × SR)
Note: RAH (Revised Actual Hours) provides an adjusted measure for labor efficiency in a mixed-labor environment.
C. Variable Cost Overhead Variances
- Variable Overhead Cost Variance: (SH × SR) - (AVO)
- Variable Overhead Expenditure Variance: (AH × SR) - (AVO)
- Variable Overhead Efficiency Variance: (SH × SR) - (AH × SR)
Note: Ensure the rate corresponds to either hours or units, as applicable to the selected calculation.
D. Fixed Cost Overhead Variances
- Fixed Overhead Cost Variance: (SH × SR) - (AFO)
- Fixed Overhead Expenditure Variance: (BFO) - (AFO)
- Fixed Overhead Volume Variance: (SH × SR) - (BFO)
- Fixed Overhead Capacity Variance: (AH × SR) - (PFO)
- Fixed Overhead Calendar Variance: (PFO) - (BFO)
- Fixed Overhead Efficiency Variance: (SH × SR) - (AH × SR)
Key Formulas:
- BFO (Budgeted Fixed Overheads) is calculated as Budgeted Output × Standard Rate or Standard Output × Standard Rate
- PFO (Possible Fixed Overheads) adjusts BFO based on days worked and is calculated as BFO × Actual Days / Budgeted Days
Why Use This Calculator?
This Cost Variance Calculator saves time and effort, enabling students to focus on learning rather than manual calculations. Each variance result is broken down step-by-step, showing the reasoning and calculation path from start to finish. Additionally, it visually indicates outcomes as Favourable or Adverse, making it easier for users to interpret the results at a glance.
For students of CA and UGC NET, this calculator serves as an excellent practice tool for understanding and mastering cost variance concepts in a real-world context, offering clear explanations of each step in the process.
