Key takeaways
- BEP = Fixed Costs ÷ (Price − Variable Cost).
- Price minus Variable Cost is called the contribution margin.
- If the variable cost per unit exceeds the price, there's no break-even point at all.
- The result is a count of units, not a currency amount.

What is the break-even point?
Running a business usually involves two kinds of costs: fixed costs, which stay the same no matter how much you sell (like rent), and variable costs, which change with each unit made or sold (like materials). The break-even point is the exact number of units where total revenue equals total costs — the business is neither making nor losing money.
Why does the break-even point matter?
Before launching a product, knowing the break-even point tells you whether your pricing plan is realistic, and how many sales you actually need before you start seeing real profit.
A small business with $12,000 in monthly fixed costs, selling a $50 product that costs $30 to make, needs to sell exactly 600 units a month just to cover its costs.
The formula
| Symbol | What it means | Example |
|---|---|---|
| Fixed Costs | Total costs that don't change with sales | $12,000 |
| Price | How much you sell each unit for | $50 |
| Variable Cost | Cost to make or buy each unit | $30 |
| BEP | Units needed to sell to break even | 600 |
How to find the break-even point step by step
- 1Subtract the variable cost from the price. This is the contribution margin — how much each sale contributes toward covering fixed costs.
- 2Divide the fixed costs by that contribution margin. This spreads the fixed costs across the profit each unit provides.
- 3The result is the break-even point in units. Selling exactly this many units means revenue equals total costs.
- 4Any units sold beyond that number generate profit. Each additional sale adds the full contribution margin to profit.

Common mistakes to avoid
- Forgetting the price must exceed the variable cost. If the variable cost per unit is higher than the price, the business loses more money with every sale, and there's no break-even point.
- Ignoring the units. The result is a count of units, not a currency amount — multiply by the price if you want the break-even revenue instead.
- Leaving out real fixed costs. Insurance, software subscriptions, and salaries are easy to forget but still count as fixed costs.
Tips and tricks
- To find break-even revenue instead of units, multiply the BEP result by the price per unit.
- Pairs well with the profit margin calculator for checking whether a pricing strategy is healthy beyond just breaking even.
- For looking at a single sale rather than the whole business, use the profit or loss calculator instead.
Where you'll use it in real life
- Launching a product: deciding on a price and sales target before spending money on production.
- Small business planning: checking whether current sales volume covers fixed monthly costs like rent and salaries.
- Pricing decisions: seeing how a price change shifts the number of units needed to break even.
- Investor pitches: break-even analysis is a standard part of showing a business plan is realistic.
Quick summary
Break-even point is BEP = Fixed Costs ÷ (Price − Variable Cost): find the contribution margin first, then divide the fixed costs by it. The result tells you exactly how many units must sell before a business turns a profit. Use the calculator above to test your own numbers.
Worked example
A small business has $12,000 in fixed monthly costs, sells its product for $50 per unit, and each unit costs $30 to make.
- 01BEP = Fixed Costs / (Price - Variable Cost)
- 02Contribution per unit = $50 - $30 = $20
- 03BEP = 12000 / 20
- 04BEP = 600 units
These numbers are pre-filled in the calculator above.
Frequently asked questions
What happens if I sell fewer units than the break-even point?
The business is operating at a loss, because total revenue hasn't yet covered the fixed costs. Selling more units, raising the price, or cutting costs all move the break-even point closer.
How do I lower my break-even point?
You can raise the selling price, lower the variable cost per unit, or reduce fixed costs — any of these increases the contribution margin or shrinks what needs to be covered, both of which reduce the number of units needed to break even.
What's the difference between fixed and variable costs?
Fixed costs stay the same regardless of sales volume, like rent or insurance. Variable costs rise and fall with each unit produced or sold, like raw materials or packaging.
Can the break-even point be a decimal, like 1,250.5 units?
Mathematically yes, but in practice you round up to the next whole unit, since you can't sell half a physical unit and still cover all your costs.
