Fixed costs ($/mo)

Variable cost/unit ($)

How it works

Finds how many units you must sell each month to cover fixed costs given your price and per-unit variable cost.

Who it's for: Small business owners, side hustlers, Etsy sellers, and product managers evaluating whether a venture is viable.

Computes break-even units as fixed costs ÷ (price per unit − variable cost per unit).

Also shows Revenue at break-even — total sales dollars at that volume.

Assumes a single product with constant price and variable cost; no step costs or discounts.

Enter Fixed costs in dollars per month — rent, salaries, software subscriptions, and other costs that do not change with volume.
Enter Price per unit — what you charge the customer before tax.
Enter Variable cost per unit — materials, shipping, payment processing, or commission per sale.
Read Units to break even — the monthly sales volume where profit equals zero.
Check Revenue at break-even to see the dollar sales target you need to hit.
If variable cost exceeds price, break-even is impossible — raise price or cut costs.

Include a profit margin target by adding desired monthly profit to fixed costs before calculating.
Seasonal businesses should use average monthly fixed costs or run separate peak/off-peak scenarios.
