Result interpretation
How to read the result
- Sales below break-even produce a loss.
- Sales above break-even start contributing to profit.
- If fixed costs or variable costs are understated, the break-even point will look too low.
Formula
Formula used
Break-even units = Fixed costs / (Selling price per unit - Variable cost per unit)
The difference between selling price and variable cost is contribution margin per unit. Fixed costs are recovered from that contribution.
Example
Break-even example
- Fixed costs = 10,000
- Selling price per unit = 50
- Variable cost per unit = 30
10,000 / (50 - 30) = 500 units
You need to sell 500 units before the product covers fixed and variable costs.
Common mistakes
Check these before deciding
- Leaving out fixed costs such as software, rent, salaries, or insurance.
- Using average selling price without accounting for discounts or refunds.
- Treating variable costs as fixed costs.
Limitations
What this estimate does not cover
- Break-even assumes price, variable cost, and fixed costs stay stable.
- It does not predict demand or cash timing.
Use this as a planning estimate and validate costs before committing spend.
Methodology
How this calculator handles inputs
This calculator uses the values you enter above and applies the formula explained in the guide below. Results update in the browser and are intended for quick planning, comparison, and sanity-checking.
- Use consistent periods, currencies, and units across inputs.
- Review any assumptions before using the result in a decision.
- Recalculate when rates, prices, tax rules, or business terms change.

How it works
Break-Even Calculator
Use this calculator to estimate how many units you need to sell before your business becomes profitable.
What this calculator tells you
This tool calculates:
- The number of units you need to sell to cover your costs
- The revenue required to break even
- Your contribution margin per unit
- How much profit each additional sale generates
How to interpret your result
Your break-even point tells you the minimum sales volume required before you start making a profit.
- If your break-even number is low, your business can become profitable quickly
- If it is high, you will need strong demand or improved margins
The most important question is:
Can you realistically sell this number of units?
Example
If:
- Fixed costs = 10,000
- Selling price = 100
- Variable cost = 60
Then:
- Contribution per unit = 40
- Break-even = 250 units
Once you sell more than 250 units:
- Every additional sale generates 40 profit
How to reduce your break-even point
There are only three ways to lower your break-even:
1. Increase your price
Even small price increases have a large impact.
2. Reduce variable costs
Lower production, shipping, or supplier costs.
3. Reduce fixed costs
Cut overhead like rent, software, or staffing.
What is a good break-even point?
There is no universal number.
A “good” break-even point is:
- achievable within your expected sales volume
- realistic based on your market demand
- aligned with your growth timeline
Break-even for ecommerce businesses
For ecommerce:
- Include shipping, transaction fees, and returns in variable costs
- Factor in ad spend when calculating realistic margins
- Test different pricing scenarios to find a sustainable model
Break-even for service businesses
If you sell services:
- Use revenue-based break-even instead of units
- Focus on billable hours or contracts
- Consider capacity limits when setting targets
Common mistakes
- Underestimating variable costs
- Ignoring platform or payment fees
- Using unrealistic pricing assumptions
- Forgetting fixed costs like subscriptions or tools
