How to Calculate Flexible Budget
A flexible budget adjusts based on output or sales volume. Here’s how to calculate it:
- Determine your expected **output/activity level** (units sold, hours worked, etc.)
- Multiply output by **variable cost per unit**
- Add **fixed costs** (which don’t change)
- The sum is your **flexible budget** for that output level

💡 What Is a Flexible Budget?
A flexible budget is a dynamic financial plan that changes based on actual output, sales volume, or service activity. It allows you to compare actual vs expected costs more accurately and control variable expenses.
✅ How to Calculate a Flexible Budget – Step-by-Step
Step 1: Separate Fixed and Variable Costs
- Fixed costs: Rent, salaries, insurance
- Variable costs: Raw materials, utilities, commissions
Step 2: Identify the Cost Behavior Formula
Variable Cost = Cost per Unit × Activity Level
Total Cost = Fixed Cost + (Variable Cost × Actual Units)
Step 3: Input Actual Activity Level
Insert actual units produced, hours worked, or revenue generated.
Step 4: Apply the Formula
Adjust the variable part of the budget using the actual output to calculate your flexible budget total.
Step 5: Compare with Actuals
Compare your flexible budget with actual financials to find variances.
🧠 Example:
| Category | Fixed Cost | Variable Cost/unit | Output (units) | Total Cost |
|---|---|---|---|---|
| Salaries | ₹50,000 | — | — | ₹50,000 |
| Raw Materials | — | ₹30 | 3,000 | ₹90,000 |
| Power | — | ₹5 | 3,000 | ₹15,000 |
| Misc Fixed | ₹10,000 | — | — | ₹10,000 |
✅ Flexible Budget Total = ₹50,000 + ₹90,000 + ₹15,000 + ₹10,000 = ₹1,65,000
