Free tool
Find your break-even point
Enter your fixed costs, price, and variable cost per unit to get your break-even point, revenue, and margin instantly. Free, no signup.
Free, no signup. Nothing you enter here is stored.
How it works
Enter your fixed costs
Rent, salaries, software — whatever stays the same regardless of how much you sell each month.
Enter price and variable cost
What you charge per unit, and what it actually costs you to produce or deliver each one.
See your break-even point
Instantly get the units and revenue needed to cover costs, plus your contribution and gross margin.
Why use this tool
Four numbers from three inputs
Break-even units, break-even revenue, contribution margin, and gross margin all calculate from the same three numbers.
Instant recalculation
Change your price or costs and see immediately how the break-even point shifts — no spreadsheet to rebuild.
Catches an impossible scenario
If your price doesn't cover your variable cost, the tool flags it clearly instead of showing a nonsensical negative break-even point.
No accounting background needed
Plain field labels (not accounting jargon) make this usable without a finance degree.
Free, no signup, no limit
Model as many pricing scenarios as you want with no account and no cap.
Nothing you enter is stored
Cost and pricing figures stay in your browser — nothing is logged or sent to a server.
When you'd actually use this
Pricing a new product or service
Test different price points to see how each one changes the number of units you need to sell to break even.
Deciding whether to take on a fixed cost
Model how a new hire or subscription (a new fixed cost) changes your break-even point before committing to it.
Evaluating a discount or promotion
See how a temporary price cut affects the units needed to break even during that period.
Writing a business plan
Break-even analysis is a standard section lenders and investors expect — get the numbers right before writing the narrative around them.
Checking if a cost increase is sustainable
Model rising supplier costs (variable cost) against your current price to see the new break-even point.
Tips for best results
- 1Be honest about which costs are truly fixed — a cost that scales with sales volume (like payment processing fees) belongs in variable cost, not fixed cost.
- 2Recalculate whenever your pricing or cost structure changes — break-even isn't a one-time calculation for a growing business.
- 3A low contribution margin means you need very high volume to be profitable — check whether that volume is realistic before committing to a price.
- 4Use monthly fixed costs and a monthly break-even target for the clearest, most actionable read on the number.
Frequently asked questions
What is a break-even point?
It's the number of units you need to sell (or the revenue you need to generate) for total revenue to exactly equal total costs — beyond that point, each additional sale contributes to profit.
What is contribution margin?
It's the price per unit minus the variable cost to produce or deliver that unit — the amount each sale contributes toward covering fixed costs and, beyond break-even, toward profit.
What counts as a fixed cost versus a variable cost?
Fixed costs (rent, salaries, software subscriptions) stay the same regardless of how much you sell; variable costs (materials, per-unit shipping, payment processing fees) scale directly with each unit sold.
Does this calculator store the numbers I enter?
No — every calculation happens in your browser and nothing is saved or sent anywhere.
What if my break-even point looks impossibly high?
That usually means fixed costs are too high relative to your contribution margin — consider whether the price can go up, variable costs can come down, or some fixed costs can be cut or delayed.
Does break-even analysis account for taxes?
No — this calculates a pre-tax break-even point based on operating costs and pricing; taxes are a separate consideration on top of the profit generated beyond break-even.
Is a service business calculated the same way as a product business?
Yes — treat a billable hour or a client engagement as the "unit," with your rate as price and any direct costs (subcontractors, tools tied to delivery) as variable cost per unit.
How is gross margin different from contribution margin here?
In this calculator, gross margin is shown as contribution margin expressed as a percentage of price — a quick way to see what share of each sale is profit before fixed costs are covered.
