Break-Even Analysis

Break-even is the sales level at which revenue exactly covers fixed and variable costs. Divide monthly fixed costs by contribution per unit (price minus variable cost) to get break-even units, or by the contribution margin ratio to get break-even revenue. Anything sold above it contributes to profit.

Getting the inputs right

  • Fixed: rent, salaries, software subscriptions, loan EMIs, insurance
  • Variable: raw material, packaging, shipping, payment gateway and marketplace fees, commissions
  • Use prices net of GST — GST collected isn't revenue
  • Rerun it whenever prices, costs or the team change

Worked example: D2C product brand

  1. 1Fixed costs ₹6,00,000 a month; selling price ₹1,000 (excluding GST); variable cost ₹600.
  2. 2Contribution = ₹400 per unit; ratio = 40%.
  3. 3Break-even = ₹6,00,000 ÷ ₹400 = 1,500 units, or ₹15 lakh revenue a month.

Selling 2,000 units gives ₹2 lakh profit and a 25% margin of safety.
