Break-Even Calculator — Units & Revenue to Profitability
Enter your fixed costs, price per unit, and variable cost per unit to find your break-even point—the minimum sales needed to cover all costs.
Rent, salaries, insurance, subscriptions—costs that don't change with sales

Understanding Break-Even Analysis
What is Break-Even Point?
The break-even point is where total revenue equals total costs—you're not making profit, but you're not losing money either. Every sale after this point is pure profit (minus variable costs).
Break-Even Units = Fixed Costs / (Price - Variable Cost) Fixed vs Variable Costs
Stay the same regardless of sales volume:
- • Rent / mortgage
- • Salaries (fixed staff)
- • Insurance premiums
- • Software subscriptions
- • Loan payments
- • Utilities (base amount)
Change with each unit sold:
- • Raw materials / inventory
- • Packaging
- • Shipping per order
- • Payment processing fees
- • Sales commissions
- • Per-unit labor
Contribution Margin
The contribution margin is how much each sale "contributes" toward covering fixed costs and then profit. It's the selling price minus variable costs.
Contribution Margin = Price - Variable Cost per Unit Using Break-Even Analysis
- • Set sales targets – Know the minimum you need to survive
- • Evaluate pricing – See how price changes affect break-even
- • Assess new costs – Understand impact of hiring or new expenses
- • Launch decisions – Determine if a new product is viable
- • Investor pitches – Show you understand your economics
Lowering Your Break-Even Point
1. Reduce fixed costs – Negotiate rent, cut unused subscriptions, go remote
2. Raise prices – Increases contribution margin per sale
3. Lower variable costs – Better supplier deals, optimize shipping
4. Increase average order value – Bundles, upsells, minimum orders
Calculate break-even for each product line separately. A product with low margins might be dragging down your overall profitability.
When to Use This Calculator
Before Launching a Product
Before committing to a product line, calculate whether you can realistically sell enough units at a viable price to cover fixed costs. A product that requires 10,000 units/month to break even may be unviable for a small business.
After Adding Fixed Costs
Every time you sign a lease, hire a salaried employee, or add a subscription, recalculate your break-even. You need to know the new minimum revenue target before committing.
Setting Sales Targets
Use the break-even point as your floor when setting monthly revenue goals. Your sales team needs to know this number — it is the minimum, not the target.
Industry Benchmarks
Typical contribution margins by business type. Higher contribution margin means you break even faster.
| Business Type | Contribution Margin | Break-Even Difficulty |
|---|---|---|
| SaaS / Software | 75–90% | Low |
| Consulting / Services | 60–80% | Low–Moderate |
| E-commerce | 30–50% | Moderate |
| Retail | 20–40% | Moderate |
| Restaurant | 25–35% | High |
Common Mistakes
Classifying semi-fixed costs incorrectly
Labor that scales with output (part-time hourly staff) is variable, not fixed. Misclassifying it understates your variable costs and makes break-even look easier than it is.
Not recalculating after cost changes
Your break-even point changes every time a fixed cost or variable cost changes. Treat it as a living number, not a one-time calculation.
Ignoring product mix
If you sell multiple products, use a weighted average contribution margin. A single product with a great margin may subsidize others with poor margins without you realizing it.
Confusing cash break-even with accounting break-even
Depreciation is a non-cash fixed cost. Your cash break-even (the point where cash flow is neutral) is different from your accounting break-even and is equally important.

Frequently Asked Questions
What is a break-even point?
The break-even point is the number of units sold (or total revenue) where your total costs equal total revenue — you are neither profitable nor losing money. Every unit or dollar of revenue above break-even contributes to profit.
How do I calculate break-even in units?
Break-Even Units = Fixed Costs / (Selling Price - Variable Cost per Unit). The denominator is called the contribution margin per unit. For example, if fixed costs are $5,000/month, selling price is $50, and variable cost is $20, then break-even = 5000 / 30 = 167 units.
How can I lower my break-even point?
Four strategies: (1) Reduce fixed costs — negotiate rent, cut subscriptions, go remote. (2) Raise prices — increases contribution margin per sale. (3) Lower variable costs — better supplier deals, optimize shipping. (4) Increase average order value — bundles, upsells, minimum orders.
What is contribution margin?
Contribution margin is the amount each unit sold contributes toward covering fixed costs. Contribution Margin = Selling Price - Variable Cost per Unit. A higher contribution margin means fewer units needed to break even. Check PlainBizBench for typical contribution margins by industry.
How long does it typically take a small business to break even?
Most small businesses take 2-3 years to reach break-even on total startup investment, though monthly cash flow break-even (covering operating expenses) can be achieved in 6-18 months. Service businesses typically break even faster than product-based businesses because variable costs are lower.
