What is the break-even point?

Your break-even point is the number of units you must sell to cover all your costs — the moment you stop losing money and start making it. Below it you're in the red; above it, every additional sale is profit.

Break-even units = Fixed costs ÷ (Price per unit − Variable cost per unit)

With $10,000 in fixed costs, a $50 price, and $30 variable cost per unit, you break even at $10,000 ÷ ($50 − $30) = 500 units, or $25,000 in revenue.

How to calculate break-even (step by step)

  1. Sum your fixed costs — rent, salaries, software subscriptions, insurance. Everything that doesn't change with sales volume.
  2. Determine your variable cost per unit — materials, packaging, shipping, transaction fees. What each additional sale costs you.
  3. Calculate contribution margin per unit = Price − Variable cost per unit.
  4. Divide fixed costs by contribution margin — the result is your break-even point in units.
  5. Multiply by price — that's your break-even revenue.

Worked example: contribution margin building to break-even

A small DTC brand with the following economics:

Input Value
Fixed costs (monthly) $12,000
Price per unit $60
Variable cost per unit $24
Contribution margin per unit $36
Break-even units 334 units
Break-even revenue $20,040

Now watch how contribution margin accumulates as sales grow:

Units sold Total contribution Cumulative vs fixed costs Status
100 $3,600 −$8,400 Still in the red
200 $7,200 −$4,800 Approaching break-even
300 $10,800 −$1,200 Almost there
334 $12,024 $0 Break-even reached
400 $14,400 +$2,400 Now in profit
500 $18,000 +$6,000 Each unit past 334 is pure profit

Every unit sold past 334 drops $36 of contribution margin straight to the bottom line. Before 334, you haven't yet covered rent and salaries. This is why the break-even point is the most important volume target in any business — it's the minimum viable scale.

What-if: price change impact

Raise the price from $60 to $70 (variable cost stays $24):

Change Before After
Contribution margin per unit $36 $46
Break-even units 334 261
Break-even revenue $20,040 $18,270

A $10 price increase drops the break-even point by 22% — 73 fewer units to cover the same fixed costs. That's why pricing is often the highest-leverage business decision.

The key idea: contribution margin

The denominator — price minus variable cost — is your contribution margin per unit: the slice of each sale left over to cover fixed costs. At $36 per unit here, it takes 334 units to cover $12,000 of fixed costs. Raise your price or cut variable costs and the contribution margin grows, so you break even sooner. If price is below variable cost, contribution is negative and you can never break even no matter how much you sell — the calculator will flag this.

Why break-even analysis matters

Break-even analysis tells you the minimum viable scale of a product, campaign, or whole business. It answers questions like: "Can this product ever pay for itself?" "How many units do I need to sell before I can quit my day job?" "Does this marketing campaign generate enough volume to cover its own cost?"

Pair it with your profit margin to set realistic sales targets, your marketing budget to decide how much ad spend is affordable, and the contribution margin calculator to drill into the variable vs fixed cost split.

The benchmarks table below serves two purposes: the top rows show contribution margins by industry (use these to calibrate your price and cost inputs), and the bottom rows show typical break-even timelines (the time dimension — how long businesses in those industries usually take to reach profitability). Your calculator results give the volume dimension: exactly how many units and how much revenue you need. Together they tell you whether the numbers are achievable in your market.

Industry benchmarks

Typical SaaS contribution margin 70–80% (very high — breaks even fast)
Typical ecommerce contribution margin 40–60%
SaaS (bootstrapped / SMB) 12–24 months to break even
E-commerce (lean / DTC) 6–18 months to break even
Retail (brick & mortar) 2–3+ years to break even
Restaurant 3–5 years typical

Frequently asked questions

How do you calculate the break-even point?

Divide fixed costs by the contribution margin per unit (price minus variable cost per unit). For example, $10,000 in fixed costs with a $20 contribution margin breaks even at 500 units.

What is contribution margin?

Contribution margin is price per unit minus variable cost per unit — the portion of each sale that goes toward covering fixed costs and then profit. A higher contribution margin lowers your break-even point.

What is the difference between fixed and variable costs?

Fixed costs stay the same regardless of how much you sell (rent, salaries, software). Variable costs change with each unit sold (materials, shipping, transaction fees). Both are needed to find your break-even point.

How do I lower my break-even point?

Reduce fixed costs, raise your price, or cut variable cost per unit. Any of these increases the contribution margin or shrinks what it must cover, so you reach profitability with fewer sales.

What is break-even revenue?

Break-even revenue is the total sales dollars you need to cover all costs — break-even units multiplied by your selling price. This calculator shows both so you can set revenue targets alongside unit targets.

Can break-even analysis be used for a new product?

Yes — it is one of the best early tests for a new product. Enter your expected fixed costs, price, and variable cost per unit to see how many units you must sell before the product pays for itself.
