About the Break-Even Calculator
Before launching a product, setting a price, or scaling a business, knowing your break-even point is fundamental. It tells you exactly how many units you need to sell — or how much revenue you need to generate — before you start making a profit. This calculator computes your contribution margin, break-even units, and break-even revenue instantly from three simple inputs.
How Break-Even Analysis Works
Every sale you make contributes a fixed amount toward covering your fixed costs. That amount — the contribution margin per unit — is the difference between your selling price and what it costs to produce or deliver one unit. Once enough units are sold to cover all fixed costs in total, you've reached break-even. Every unit sold beyond that generates pure profit (before taxes).
Formula
Contribution Margin / Unit = Selling Price − Variable Cost / Unit
Break-Even Units = Fixed Costs ÷ Contribution Margin / Unit
Break-Even Revenue = Break-Even Units × Selling Price
Contribution Margin Ratio = Contribution Margin / Unit ÷ Selling Price
Fixed vs. Variable Costs
- Fixed costs — expenses that don't change with sales volume: rent, salaries, insurance, annual software subscriptions, equipment leases. These accrue whether you sell zero units or 10,000.
- Variable costs — expenses that scale directly with production or sales: raw materials, packaging, payment processing fees, per-unit shipping, sales commissions. These only occur when you make a sale.
When to Use This Calculator
- Product pricing — determine the minimum viable price for a product given your cost structure
- New business planning — find out how much revenue you need before the business can sustain itself
- Campaign budgeting — calculate how many conversions a paid campaign needs to cover its cost
- Service pricing — use client engagements or projects as "units" to find your break-even client load
- Evaluating a new offer — quickly test whether a new product or service is viable before investing in it
Break-even analysis is a simplified planning tool. It does not account for taxes, financing costs, inventory shrinkage, changing demand, or price elasticity. Real-world profitability depends on many additional factors.
Frequently Asked Questions
What is a break-even point?
The break-even point is the level of sales at which total revenue equals total costs — meaning the business neither makes a profit nor suffers a loss. At break-even, every dollar of contribution margin from sales exactly covers fixed costs. Sales beyond break-even generate profit; sales below it result in a loss.
How do you calculate break-even units?
Break-even units = Fixed Costs ÷ Contribution Margin Per Unit. The contribution margin per unit is simply selling price minus variable cost per unit. For example, if fixed costs are $10,000, selling price is $50, and variable cost is $30, the contribution margin is $20 and break-even is 500 units.
What is the difference between fixed and variable costs?
Fixed costs stay constant regardless of sales volume — rent, insurance, salaries, software subscriptions, and equipment depreciation are common examples. Variable costs change directly with production or sales volume — raw materials, packaging, payment processing fees, and sales commissions are typical variable costs.
Why can a business fail to break even at its current price?
If the selling price is less than or equal to the variable cost per unit, the contribution margin is zero or negative — meaning every sale either breaks even on unit economics or actively loses money. In this case, no volume of sales can cover fixed costs. The business must either raise prices or cut variable costs.
Should break-even units be rounded up?
Yes. Since you cannot sell a fraction of a unit (in most businesses), the break-even point should be rounded up to the nearest whole unit. Selling exactly the fractional break-even quantity would leave a small loss; the next whole unit above it puts you into profit.
Can service businesses use a break-even calculator?
Absolutely. For service businesses, treat each 'unit' as a client engagement, project, or service package. Fixed costs are your overhead (office, staff, subscriptions), selling price is your average project fee, and variable cost is what you spend on each project (contractor fees, software, direct materials). The same formula applies.
Does break-even mean I am making a profit?
No. Break-even means you are covering all costs but earning zero profit. To generate profit, you need to sell more units than the break-even quantity. Break-even analysis is a floor, not a goal — it tells you the minimum you need to sustain operations, not the volume you need to earn a meaningful return.
