This free break-even calculator from Nemin.io tells you how many units you need to sell to cover your costs. Enter your fixed costs, selling price per unit and variable cost per unit to see your break-even units, break-even revenue and contribution margin per unit.
It’s a simple way to test prices, plan a product launch or understand how much you need to sell each month before you start making a profit.

How the Nemin.io Break-Even Calculator Works
- Contribution margin per unit = selling price − variable cost per unit
- Break-even units = fixed costs ÷ contribution margin, rounded up to a whole unit
- Break-even revenue = break-even units × selling price
If the variable cost is equal to or higher than the price, the calculator shows 0 units, because each sale loses money and you can never break even at that price.
Worked Example
Fixed costs of $6,000 a month, a $50 selling price and a $20 variable cost give a contribution of $30 per unit. You need to sell 200 units, or $10,000 in revenue, each month to break even. Raising the price to $55 cuts the break-even point to 172 units.
How to Use the Nemin.io Break-Even Calculator
- Enter Fixed costs ($).
- Enter Selling price per unit ($).
- Enter Variable cost per unit ($).
- Click Calculate break-even to see your results instantly.
- Change one input at a time to compare scenarios, then click Reset to start again.
The Break-Even Calculator runs entirely in your browser, so you can test as many scenarios as you like.
Fixed Costs vs Variable Costs
| Fixed costs | Variable costs |
|---|---|
| Stay the same regardless of sales | Rise and fall with each unit sold |
| Rent, salaries, software, insurance | Materials, packaging, shipping, payment fees |
Getting this split right is the most important step. Misclassifying costs can make the break-even point look much better or worse than it is.
Ways to Lower Your Break-Even Point
- Raise prices to increase contribution per unit.
- Reduce variable costs through better suppliers or processes.
- Cut fixed costs you don’t need.
- Sell higher-margin products or bundles.
How Price Changes Your Break-Even Point
With $6,000 in fixed costs and a $20 variable cost per unit, here’s how the selling price changes the break-even point:
| Price | Contribution per unit | Break-even units | Break-even revenue |
|---|---|---|---|
| $40.00 | $20.00 | 300 | $12,000.00 |
| $50.00 | $30.00 | 200 | $10,000.00 |
| $55.00 | $35.00 | 172 | $9,460.00 |
| $60.00 | $40.00 | 150 | $9,000.00 |
Small price changes can move the break-even point a lot, because they change the contribution from every single unit.
Who the Break-Even Calculator Is For
- Founders planning a product launch
- Small businesses setting sales targets
- Ecommerce sellers testing prices
- Service businesses working out how many clients they need
- Anyone considering a new fixed cost such as rent or hiring
Break-Even for Service Businesses
Service businesses can use the same formula. Treat each client, project or billable hour as a unit, use your price per unit and the direct cost of delivering it (such as contractor fees) as the variable cost. For example, if each client pays $1,500 a month and costs $500 to serve, with $6,000 in monthly fixed costs, you need 6 clients to break even.
Using Break-Even Analysis to Plan
Break-even analysis is useful before launching a product, hiring, signing a lease or changing prices. Run several scenarios in the calculator to see how sensitive your break-even point is to price and cost changes, then plan sales targets with a margin of safety above the break-even level.
Key Terms Explained
- Fixed costs: Costs that stay the same regardless of sales, such as rent and salaries.
- Variable costs: Costs that rise with each unit sold, such as materials and shipping.
- Contribution margin: Price minus variable cost; what each unit contributes to fixed costs.
- Break-even point: The sales level where total revenue equals total costs.
- Margin of safety: How far sales can fall before you drop below break-even.
Tips for Accurate Break-Even Calculator Results
- Separate fixed and variable costs carefully.
- Use the average selling price after discounts.
- Include payment and shipping fees as variable costs.
- Plan sales targets above break-even for a margin of safety.

Break-Even Calculator FAQs
Is the Nemin.io break-even calculator free?
Yes. It’s free to use with no account.
How do I calculate my break-even point?
Divide fixed costs by the contribution margin per unit (price minus variable cost).
Why are units rounded up?
You can’t sell part of a unit, so the calculator rounds up to the first whole unit that covers your costs.
What if the result is 0?
Your variable cost is equal to or higher than your price, so each sale loses money.
Can service businesses use it?
Yes. Treat a client, project or hour as the unit.
Is break-even the same as profit?
No. Break-even is the point where profit is zero; every unit after that adds profit.
How do I calculate break-even in sales dollars?
Divide your fixed costs by the contribution margin ratio, which is (price − variable cost) ÷ price. For example, with $10,000 in fixed costs, a $50 price and a $30 variable cost, the ratio is 40%, so break-even sales are $10,000 ÷ 0.40 = $25,000. The calculator shows break-even revenue as break-even units × price, which gives the same answer, apart from rounding units up to whole numbers.
How many clients do I need to break even?
Treat each client as a unit. Enter your monthly fixed costs, the average monthly fee per client as the price, and the direct cost of serving one client as the variable cost. The break-even units result is the number of clients you need. Our guide on how many clients you need to break even walks through this in more detail.
What is the margin of safety?
The margin of safety shows how far sales can fall before you reach break-even. It’s calculated as (current sales − break-even sales) ÷ current sales. A larger margin of safety means more room to absorb a slow month.
What is break-even analysis used for?
Break-even analysis helps you test prices, decide whether a product or service is worth launching, set sales targets and see how changes in costs affect profitability. It’s a planning tool and assumes your price and costs per unit stay the same.
