Break-Even Analysis Calculator
Calculate the exact units and revenue needed to cover all costs and reach profitability for any business or product.
Business Parameters
Rent, salaries, insurance, subscriptions — costs that don't change with sales volume.
Materials, production, shipping, commissions — costs that increase with each unit sold.
Your expected or target sales volume for this period (optional — for margin of safety calculation).
Quick Tips
- Contribution Margin = Selling Price − Variable Cost per Unit.
- Higher contribution margin = fewer units needed to break even.
- Margin of safety >25% gives reasonable cushion against sales shortfalls.

Simplifications
This calculator assumes a linear relationship between sales volume and costs, and a single product at a fixed price. Multi-product businesses should calculate weighted average contribution margin. Also consider taxes and financing costs for a complete P&L picture.
What Is Break-Even Analysis?
Break-even analysis is a financial calculation that identifies the exact sales volume at which total revenue equals total costs — the "break-even point." At this point, a business neither makes a profit nor incurs a loss. Every unit sold above the break-even point contributes pure profit; every unit below it results in a loss. Understanding your break-even point is one of the most fundamental exercises in business planning and financial management.
The break-even concept is built on the distinction between fixed costs (which don't change with volume) and variable costs (which scale with each unit produced or sold). The contribution margin — selling price minus variable cost per unit — measures how much each sale contributes toward covering fixed costs. Once total contributions from all sales equal total fixed costs, you've broken even.
Break-even analysis is used by entrepreneurs evaluating new business ideas, product managers pricing new products, CFOs stress-testing financial models, and operations teams planning production capacity. It provides an objective threshold for viability before committing resources to a business or product line.
How to Calculate the Break-Even Point
Formulas
Contribution Margin = Selling Price − Variable Cost per Unit
Break-Even Units = Fixed Costs ÷ Contribution Margin
Break-Even Revenue = Break-Even Units × Selling Price
Margin of Safety = (Planned Units − Break-Even Units) ÷ Planned Units × 100%
Fixed Costs — rent, salaries, insurance: costs that don't vary with volume
Variable Cost per Unit — materials, shipping, commissions: costs that scale with volume
Contribution Margin — the amount each unit contributes to covering fixed costs and profit
Worked Examples
Example 1: E-commerce Product
Fixed costs: $5,000/mo | Selling price: $45 | Variable cost: $18 | Contribution margin: $27
Break-Even Units = $5,000 / $27 = 186 units | Break-Even Revenue = 186 × $45 = $8,370. Sell 187+ units to be profitable.
Example 2: SaaS Startup
Fixed costs: $30,000/mo (team + infrastructure) | MRR per customer: $99 | Variable cost per customer: $5 (hosting, support) | CM: $94
Break-Even Customers = $30,000 / $94 = 320 customers | Break-Even MRR = $31,680/mo ($380K ARR). This is the MRR milestone where the business becomes self-sustaining.
Example 3: Restaurant
Fixed costs: $15,000/mo | Average check per cover: $35 | Variable cost per cover (food + direct labor): $14 | CM: $21
Break-Even Covers = $15,000 / $21 = 714 covers/mo | Break-Even Revenue = $25,000/mo. At 50 covers/day (6-day week), you break even at just ~24 covers/day.
Break-Even Analysis Across Business Types
| Business Type | Typical CM % | Fixed Cost Range | Key Variable Costs |
|---|---|---|---|
| SaaS / Software | 70%–90% | $10K–$200K/mo | Hosting, support, payment processing |
| E-commerce (Physical) | 30%–60% | $2K–$50K/mo | COGS, shipping, platform fees |
| Restaurant / Food | 40%–65% | $8K–$40K/mo | Food cost (~30%), direct labor |
| Consulting / Services | 60%–85% | $5K–$50K/mo | Contractor fees, tools per project |
| Manufacturing | 20%–50% | $20K–$500K/mo | Raw materials, direct labor, energy |
When to Use This Calculator
- New product launches: Before investing in production or marketing, calculate whether the product can realistically generate enough volume to cover its costs.
- Pricing decisions: Model how a price increase or decrease shifts the break-even point and affects risk exposure.
- Business plan validation: Include break-even analysis in your business plan to show investors when the business becomes self-sustaining.
- Cost structure changes: When adding fixed costs (new hire, new office), recalculate break-even to understand how much additional revenue is needed to justify the investment.
- Scenario planning: Run conservative, base, and optimistic scenarios to understand the risk range before committing capital.
Tips for Lowering Your Break-Even Point
- Increase your price before cutting costs. A 10% price increase on a product with a 40% contribution margin reduces break-even units by roughly 20%. Test pricing with small segments before a full rollout.
- Negotiate variable costs relentlessly. Every $1 reduction in variable cost per unit improves your contribution margin by $1 and reduces break-even units proportionally. Supplier negotiations, shipping optimization, and process efficiency all count.
- Audit fixed costs quarterly. Software subscriptions, office space, and redundant services often accumulate. Reducing fixed costs by $1,000/month cuts break-even units by $1,000 ÷ Contribution Margin.
- Use break-even to set minimum viable sales targets. Before committing to a campaign or product, set a hard decision rule: if sales don't reach break-even within X weeks, pause and evaluate. This prevents throwing good money after bad.
- Model multiple scenarios before launching. Calculate break-even under pessimistic (lower price, higher costs), base, and optimistic scenarios. If even the optimistic scenario barely breaks even, the risk-reward profile is unfavorable.
Frequently Asked Questions
About This Calculator
Calculate break-even point using fixed costs, variable cost per unit and unit price. The tool shows units and revenue needed to break even, with clear formulas to help you test price or cost scenarios and understand contribution margin impacts.
Frequently Asked Questions
How is the break-even point calculated?
Break-even units = Fixed Costs 梅 (Price 鈭?Variable Cost per Unit). Break-even revenue = Break-even units 脳 Price.
What inputs do I need?
Provide total fixed costs, variable cost per unit and unit price. Optionally adjust assumptions to see how contribution margin shifts the break鈥慹ven point.
What is contribution margin?
Contribution margin per unit = Price 鈭?Variable Cost per Unit. It represents how much each unit contributes to covering fixed costs and then profit.
What is the margin of safety?
Margin of Safety = (Planned Units − Break-Even Units) ÷ Planned Units × 100%. It shows how far sales can drop before you hit break-even and start losing money. A margin of safety above 25% is considered healthy for most businesses.
How can I lower my break-even point?
Three levers: (1) Increase selling price — even a 10% increase significantly reduces break-even units if demand is price-inelastic. (2) Reduce variable costs — negotiate supplier prices, optimize shipping, reduce waste. (3) Reduce fixed costs — review all subscriptions and overheads. A combination of all three is usually most effective.
