What Is Break-Even Analysis?
Break-even analysis determines the exact point where your business generates enough revenue to cover all costs — the point where you stop losing money and start making it. Every founder and operator should calculate their break-even point before launching a product, hiring a new employee, or scaling ad spend.
The Break-Even Formula
Break-Even Units = Fixed Costs ÷ (Selling Price – Variable Cost per Unit)
Break-Even Revenue = Fixed Costs ÷ Gross Margin %
Example Calculation
A SaaS product with:
- Fixed costs (salaries, office, software): $15,000/month
- Price: $99/month per customer
- Variable cost: $15/month per customer (support, infrastructure)
- Contribution margin per customer: $84/month
Break-even = $15,000 ÷ $84 = 179 customers
At 179 paying customers, you stop burning cash on operations. Use the Break-Even Calculator to model this for your specific cost structure.
Fixed Costs vs Variable Costs
Fixed costs: Costs that don't change with sales volume — rent, salaries, subscription software, loan payments.
Variable costs: Costs that scale with each unit sold — raw materials, payment processing fees, per-user infrastructure costs.
Mixed costs: Costs with both components — shipping (flat base + per-order), support (base team + volume-based calls).
Misclassifying costs is the most common break-even error. Treating variable costs as fixed overstates the break-even point. Treating fixed costs as variable understates it.
Break-Even for SaaS Businesses
SaaS break-even is unique because revenue is recurring — you don't re-earn a customer's value monthly, but you also don't lose it unless they churn. SaaS break-even analysis must factor in churn: at 5% monthly churn, your average customer lifetime is 20 months, which constrains how many customers are active simultaneously and therefore how quickly you reach break-even headcount.

Why Reaching Break-Even Changes Everything
Pre-break-even, every month is survival mode. Every customer matters desperately. Post-break-even, new customers are pure profit growth. Your entire operational psychology shifts. The fastest path to reaching break-even is usually: reduce fixed costs, increase price, or both simultaneously — not simply adding more customers.
