Fixed costs

Rent, salaries, software — costs that don’t change with volume.

Selling price per unit

Variable cost per unit

Materials, packaging, per-sale fees — costs that scale with each unit.

Optional — the volume you expect to sell, to see the profit or loss there.

Where you break even

You need to sell 400 units — about $16,000.00 in revenue — before this covers its costs. Every unit after that adds $25.00 to profit.

Cost vs. revenue

Revenue Total cost Break-even

The shaded area left of the crossover is a loss; right of it is profit. Below the break-even point revenue can’t cover total cost.

At 500 units

Revenue

$20,000.00

Total cost

$17,500.00

Profit

$2,500.00

Margin of safety

20%

100 units clear

Selling 500 units is above break-even, so it turns a profit. Margin of safety is how far sales can fall before you hit break-even.

This is a single-product break-even model (one price, one variable cost). For planning only — it assumes costs stay linear and every unit made is sold.

Find Your Break-Even Point in Seconds

Enter your fixed costs, your selling price per unit, and your variable cost per unit, and this calculator tells you exactly how many units you have to sell — and how much revenue you have to book — before you stop losing money and start making it. It also shows your contribution margin per unit, your margin ratio, and the profit or loss at any target sales volume you plug in, plus your margin of safety at that volume.

What sets it apart is the chart. Most break-even calculators hand you a single number; this one draws the actual cost-versus-revenue lines with the crossover marked, so you can see the loss region on the left, the profit region on the right, and how fast the two lines separate. Change a price or a cost and every figure and the chart update instantly.

An honest note on the model: this is a single-product break-even (one price, one variable cost per unit). It assumes your costs stay linear and that every unit you make is sold — so treat it as a fast planning estimate, not a full financial model for a mixed catalog with step costs or tiered pricing.

Common Use Cases

Pricing a new product: Test a price against your unit cost and see how many sales it takes to cover your setup and overhead.
Setting sales targets: Turn a monthly rent-and-salaries figure into a concrete unit and revenue goal for the team to hit.
Weighing a fixed commitment: Before signing a lease, hiring, or buying equipment, see how many extra units the new fixed cost forces you to sell.
Comparing suppliers: Drop in a lower variable cost per unit and watch your break-even point and margin move.
Discount decisions: Lower the price and instantly see how many more units a promotion has to move to stay above water.
Freelance and service rates: Treat a booked hour or project as a "unit" to find how much you must bill to cover your baseline expenses.

Privacy: The entire calculation runs in your browser using plain arithmetic and a canvas chart. Your costs, prices, and margins are never uploaded or sent to any server, there is no signup, and there is no limit on how many scenarios you can model.

FAQ

Frequently asked questions.

How do I find my break-even point?

Enter your fixed costs, your price per unit and your variable cost per unit. The tool shows how many units you must sell and how much revenue you need to cover your costs.

What is the break-even formula?

Break-even units equal fixed costs divided by (price minus variable cost per unit). The part in brackets is called the contribution margin.

What does the chart show?

It draws your total cost line and your revenue line. Where they cross is your break-even point. The space to the left is loss and the space to the right is profit.

Does it work for many products?

It models one product with one price and one variable cost. For a mixed catalog, treat it as a quick estimate. Yes. It is free to use with no daily limit, no account and nothing to install.
