Break-Even Analysis for Small Business: Know Exactly How Much You Need to Sell

Break-even analysis tells you the sales level where total contribution covers fixed costs. At break-even, operating profit is zero.Core formulasContribution margin per unit = Selling price minus variable cost per unit.Break-even units = Fixed costs divided by contribution margin per unit.For a multi-product business, break-even revenue equals fixed costs divided by the contribution margin ratio.Worked D2C exampleA product sells for ₹1,200. Product cost is ₹420, packaging ₹60, payment and marketplace costs ₹90, and average shipping subsidy ₹130. Variable cost is ₹700 and contribution is ₹500 per order.With monthly fixed costs of ₹3,00,000, break-even volume is 600 orders. Break-even revenue is ₹7,20,000.Use break-even for decisionsDiscountingIf a ₹200 discount cuts contribution from ₹500 to ₹300, break-even volume rises from 600 to 1,000 orders. A discount may improve conversion, but it also raises the volume required to cover costs.HiringIf a new hire adds ₹60,000 to monthly fixed costs, break-even rises to 720 orders at ₹500 contribution. The hire should support at least 120 extra contribution-positive orders or create equivalent savings or capacity.Target profitRequired units = (Fixed costs + Target profit) divided by contribution per unit. With ₹3,00,000 fixed costs, ₹2,00,000 target profit and ₹500 contribution, the business needs 1,000 orders.Margin of safetyMargin of safety = (Actual sales minus break-even sales) divided by actual sales × 100. If monthly revenue is ₹10 lakh and break-even revenue is ₹8 lakh, the margin of safety is 20%, assuming the cost structure stays similar.Monthly checklistUpdate realised prices after discounts.Include transaction costs, returns and shipping subsidies.Update fixed costs.Calculate break-even units and revenue.Compare actual sales with break-even.Run a downside scenario.Mistakes to avoidIgnoring returns and failed deliveries.Using list price instead of realised price.Treating founder labour as permanently free.Assuming the sales mix never changes.Confusing accounting break-even with cash break-even.FAQsCan freelancers use it?Yes. Treat billable projects or hours as units, direct project costs as variable costs and recurring business expenses as fixed costs.How often should you calculate it?Monthly works for many small businesses. Recalculate sooner when pricing, salaries, rent, product mix or supplier costs change materially.SourceU.S. Small Business Administration, Break-even point
