About the Safety Margin Calculator
What is the Safety Margin Calculator?
The margin of safety is the gap between your actual or budgeted sales and the break-even point. It tells you how much sales can drop before the business starts losing money.
Enter sales, fixed costs and variable costs as a share of sales to get the cushion in rupees and as a percentage.
How to use the Safety Margin Calculator
- Actual or Budgeted Sales (₹) (sample: 50,00,000)
- Fixed Costs (₹) (sample: 12,00,000)
- Variable Costs as % of Sales (sample: 60)
- Press Calculate Margin of Safety (results also refresh as you type). The result card shows the Margin of Safety, along with Margin of safety amount, Break-even sales, Operating profit (MOS × CM ratio) and Reading.
Formula used
Margin of safety % = (Sales − Break-even sales) ÷ Sales × 100
- Break-even sales = fixed costs ÷ (1 − variable cost ratio)
- Profit = margin of safety × contribution margin ratio
A negative margin of safety means sales are below break-even.

Tips for using the Safety Margin Calculator
- A margin of safety under 20% signals vulnerability to a downturn.
- Raise it by cutting fixed costs or improving the contribution ratio.
