Break-Even Calculator
Know when you'll be profitable

The break-even point is where your total revenue equals your total costs - you're not making a profit, but you're not losing money either. It's calculated in two ways: (1) Break-even units - the number of products you need to sell, and (2) Break-even revenue - the total sales dollars needed. At this point, you've covered all your fixed costs (rent, salaries, software) and variable costs (COGS, shipping, packaging). Every sale beyond break-even contributes directly to profit.

Fixed costs stay the same regardless of how many units you sell: rent, salaries, insurance, software subscriptions, utilities, loan payments. These costs exist even if you sell zero units. Variable costs change based on sales volume: cost of goods sold (COGS), shipping per unit, packaging materials, payment processing fees (2-3%), platform transaction fees. For example, if you sell 100 units vs 1,000 units, your rent stays the same (fixed) but your shipping costs multiply by 10 (variable).

Contribution margin is the amount each sale contributes to covering fixed costs and profit. Formula: Selling Price - Variable Cost per Unit. For example, if you sell a product for $100 and variable costs are $60, your contribution margin is $40. This means each sale contributes $40 toward covering fixed costs. Once fixed costs are covered, that $40 becomes pure profit. A higher contribution margin means you reach break-even faster and profit grows quicker beyond break-even.

Add up all monthly costs that don't change with sales volume: (1) Rent or mortgage for office/warehouse; (2) Salaries and benefits for full-time employees; (3) Insurance (business, liability, health); (4) Software subscriptions (Shopify, accounting, CRM); (5) Utilities (electricity, internet, phone); (6) Loan or equipment lease payments; (7) Marketing retainers or fixed ad spend. For seasonal businesses, calculate an average monthly fixed cost based on annual expenses. Don't include costs that vary with sales like inventory, shipping, or per-order fees.

Lower break-even by: (1) Reducing fixed costs - negotiate rent, use freelancers instead of full-time staff, switch to cheaper software, work remotely; (2) Lowering variable costs - negotiate supplier prices, optimize shipping carriers, reduce packaging costs, find cheaper fulfillment; (3) Increasing selling price - test 10-20% price increases, add value through branding or bundling; (4) Improving contribution margin - focus on higher-margin products, upsell accessories. Even small improvements compound: reducing fixed costs by 20% and increasing margin by 10% can cut break-even units by 30%+.

It depends on your industry and business model. Generally, aim to reach break-even within: (1) 3-6 months for bootstrapped eCommerce; (2) 12-18 months for funded startups; (3) 6-12 months for brick-and-mortar retail. For monthly operations, you want break-even low enough to achieve with realistic sales. If you need to sell 10,000 units monthly but your capacity is only 2,000, that's a problem. A sustainable business should hit break-even at 50-70% of capacity, leaving room for profit growth.

Break-even analysis shows WHEN you become profitable, while profit margin shows HOW profitable you are. They're connected through contribution margin. If your contribution margin ratio is 40%, you need to sell enough to generate revenue equal to 2.5x your fixed costs to break even (Fixed Costs ÷ 0.40). A higher contribution margin (better profit margin) means a lower break-even point. For example, with $10,000 fixed costs: 30% contribution margin = $33,333 revenue to break even. 50% contribution margin = $20,000 revenue to break even.

Calculate both, but use monthly for operational decisions. Monthly break-even helps you: track progress toward profitability, adjust marketing spend in real-time, plan cash flow and inventory purchases, set realistic sales targets. Annual break-even is useful for: investor presentations and business plans, tax planning, long-term strategic decisions, understanding seasonality patterns. For seasonal businesses, calculate separate break-even points for high and low seasons, as your fixed costs stay constant but sales vary dramatically.
