How it is calculated
Break-even revenue = Break-even units × Selling price. Units for a target profit = (Fixed costs + Target profit) ÷ Contribution per unit. Margin of safety % = (Expected − Break-even units) ÷ Expected units × 100.
Worked example
Fixed costs ₹2,00,000, price ₹500, variable cost ₹300: contribution ₹200 per unit, break-even = 2,00,000 ÷ 200 = 1,000 units (₹5,00,000 revenue). At 1,500 units, profit = 1,500 × 200 − 2,00,000 = ₹1,00,000 and margin of safety = 33.33%.
