Break-Even Point Analysis
Last reviewed: May 2026
A break-even calculator determines the exact point where total revenue equals total costs — the number of units you need to sell or the revenue level you need to reach before a business, product, or project starts generating profit. Below the break-even point, you're operating at a loss; above it, every additional sale contributes directly to profit. This is one of the most fundamental calculations in business, used for pricing decisions, startup feasibility analysis, marketing budgets, and expansion planning.1
The core formula is: Break-Even Units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit). The denominator — price minus variable cost — is called the contribution margin: how much each unit sold contributes toward covering fixed costs and eventually generating profit. For example, if your fixed costs are $10,000/month, you sell at $50/unit, and each unit costs $20 in variable costs, your break-even is 10,000 ÷ (50 − 20) = 334 units per month.2
| Scenario | Fixed Costs | Price/Unit | Variable Cost | Contribution Margin | Break-Even Units |
|---|---|---|---|---|---|
| Coffee shop | $8,000/mo | $5.00 | $1.50 | $3.50 | 2,286 |
| SaaS product | $15,000/mo | $49/mo | $3/mo | $46 | 327 subscribers |
| E-commerce | $5,000/mo | $35 | $18 | $17 | 295 orders |
| Consulting | $6,000/mo | $150/hr | $20/hr | $130 | 47 hours |
| Food truck | $4,500/mo | $12 | $4 | $8 | 563 meals |
Fixed costs remain constant regardless of sales volume: rent, salaries, insurance, loan payments, software subscriptions, and equipment depreciation. Variable costs scale with each unit sold: raw materials, packaging, shipping, payment processing fees, and sales commissions. Some costs are semi-variable — utilities, for instance, have a base cost plus usage. The accuracy of your break-even analysis depends on correctly categorizing costs. A common mistake is treating partially variable costs as entirely fixed, which understates the break-even point.
Break-even analysis reveals the relationship between pricing and volume. Raising your price from $50 to $60 increases the contribution margin from $30 to $40, reducing the break-even from 334 units to 250 — a 25% reduction in required volume. Conversely, a 20% price cut from $50 to $40 drops the margin from $30 to $20, pushing break-even from 334 to 500 units — a 50% increase in required volume. Price changes have asymmetric effects on break-even because they directly affect the contribution margin. Use our Markup vs Margin Calculator alongside this tool when setting prices.3
| Price | Variable Cost | Margin | Break-Even (at $10K fixed) | Change |
|---|---|---|---|---|
| $40 | $20 | $20 | 500 units | +50% |
| $50 | $20 | $30 | 334 units | Baseline |
| $60 | $20 | $40 | 250 units | −25% |
| $75 | $20 | $55 | 182 units | −46% |
Beyond unit-based break-even, businesses need to know when they'll break even over time. A startup with $100,000 in initial investment, $8,000/month in fixed costs, and a $5,000/month contribution margin (after variable costs) breaks even on monthly operations immediately but needs 20 months to recoup the initial investment ($100,000 ÷ $5,000). This distinction matters for investors and for planning runway — use our Startup Runway Calculator to model cash flow timelines.4
The break-even point is where total revenue equals total costs — no profit, no loss. Every unit sold beyond break-even generates profit; every unit below generates loss. The formula is straightforward: Break-Even Units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit). A coffee shop with $8,000 monthly fixed costs (rent, insurance, salaries) selling lattes at $5.50 with $1.50 in variable costs (milk, cup, lid, coffee beans) per drink breaks even at 2,000 lattes per month ($8,000 ÷ $4.00 contribution margin). At 2,500 lattes, the shop earns $2,000 profit. At 1,500 lattes, it loses $2,000. Understanding this number transforms business decisions: it tells you the minimum viable sales volume, informs pricing strategy, and reveals how cost changes affect profitability.
| Business | Fixed Costs/Mo | Price | Variable Cost | Contribution | Break-Even Units |
|---|---|---|---|---|---|
| Coffee shop | $8,000 | $5.50 | $1.50 | $4.00 | 2,000/mo |
| SaaS product | $15,000 | $49/mo | $3 | $46 | 326 subscribers |
| E-commerce (apparel) | $5,000 | $45 | $18 | $27 | 185 orders/mo |
| Freelance consultant | $3,000 | $150/hr | $10/hr | $140 | 22 hours/mo |
| Food truck | $4,500 | $12 | $4 | $8 | 563 servings/mo |
Contribution margin — the difference between selling price and variable cost per unit — is the amount each sale contributes toward covering fixed costs and generating profit. A high contribution margin means fewer sales are needed to break even and each additional sale is highly profitable. Software businesses with 90%+ contribution margins break even with relatively few customers and become extraordinarily profitable at scale. Restaurants with 30% contribution margins need high volume to cover substantial fixed costs. When evaluating pricing decisions, always think in terms of contribution margin: a 10% price increase on a product with a 40% contribution margin raises contribution by 25% (from $40 to $50 on a $100 product), which can dramatically reduce the break-even volume.

| Price Change | New Price | New Contribution | Break-Even Change | Volume Cushion |
|---|---|---|---|---|
| −20% | $40 | $22 | +82% (364→664) | Need 82% more sales |
| −10% | $45 | $27 | +35% (364→494) | Need 35% more sales |
| Base ($50) | $50 | $32 | Baseline (364) | — |
| +10% | $55 | $37 | −19% (364→295) | Can lose 19% volume |
| +20% | $60 | $42 | −32% (364→248) | Can lose 32% volume |
This table reveals a critical insight: price cuts require disproportionately large volume increases to maintain the same break-even point, while price increases provide substantial cushion for volume loss. A 10% price cut needs 35% more sales to compensate, but a 10% price increase can absorb a 19% volume decline before reaching the old break-even. This asymmetry means most businesses should test price increases before discounting, because the math almost always favors higher prices with slightly lower volume over lower prices requiring much higher volume.
When launching a new product, break-even analysis must include one-time startup costs (product development, initial marketing, tooling, licensing) in addition to ongoing fixed costs. A product requiring $100,000 in development costs, $5,000 per month in ongoing fixed costs, priced at $79 with $25 variable cost, has a contribution margin of $54 per unit. Monthly ongoing break-even is 93 units ($5,000 ÷ $54). But recovering the $100,000 development investment requires an additional 1,852 units ($100,000 ÷ $54). At 200 units per month, ongoing expenses are covered in month one, but development cost recovery takes approximately 17 months. This "payback period" analysis is essential for investment decisions: if the expected product lifecycle is only 12 months, the $100,000 investment never fully recovers. For longer horizons, the cumulative profit after payback accelerates rapidly because fixed costs are already covered.
Real business conditions are uncertain — costs fluctuate, prices face competitive pressure, and demand varies seasonally. Sensitivity analysis models break-even under multiple scenarios: best case (lower costs, higher prices), base case (current projections), and worst case (cost increases, pricing pressure). If break-even is achievable even in the worst-case scenario, the business model is robust. If break-even requires best-case assumptions, the venture carries significant risk. Model specific scenarios: what if a key supplier raises prices 15%? What if a competitor undercuts your price by $10? What if seasonal demand drops 30% for three months? Each scenario produces a different break-even volume, building a range that informs how much cash reserve the business needs to survive fluctuations.

→ Include ALL fixed costs. Don't forget insurance, software subscriptions, accounting fees, and marketing budget. Underestimating fixed costs is the most common break-even analysis error.
→ Test multiple price points. Small price increases can dramatically reduce your break-even. A 10% price increase often reduces required volume by 20–30% due to the contribution margin effect.
→ Be honest about variable costs. Payment processing fees (2.5–3.5%), returns/refunds (5–15% of sales), and shipping damage all count as variable costs.
→ Recalculate regularly. Break-even isn't static — it changes when costs, prices, or product mix shift. Revisit quarterly at minimum.

→ Break-even tells you the minimum to survive. It's not a goal — it's the floor. Your target should be 2–3× the break-even volume for a healthy business. Below break-even, every sale still loses money.
→ Include all fixed costs, even small ones. SaaS subscriptions, domain renewals, insurance, accounting fees — these add up. Underestimating fixed costs means your break-even is optimistic.
→ Run sensitivity analysis. Calculate break-even at different price points. A 10% price increase might reduce volume needed by 25% if variable costs are high relative to price. Use our Markup Calculator to optimize pricing.
→ Recalculate when costs change. New hires, rent increases, or supplier price changes shift your break-even. Review quarterly to avoid surprises.
