Rent, salaries, insurance, software, loan payments, utilities, and other monthly overhead.
Selling price must be higher than variable cost per unit. This calculator provides a simplified planning estimate and does not account for taxes, financing costs, inventory timing, or mixed product lines.
How This Calculator Works
This break-even calculator estimates how many units your business needs to sell each month before sales cover your fixed costs and variable costs. It starts with fixed monthly costs, subtracts variable cost from selling price to find contribution margin, then divides fixed costs by contribution margin.
Contribution margin is the amount each sale contributes toward covering overhead and profit. If you sell a product for $50 and it costs $20 to produce, package, and ship, the contribution margin is $30. Every unit sold contributes $30 toward rent, salaries, insurance, and other fixed costs.
If you enter current monthly sales volume, the calculator also estimates margin of safety. That shows how far above or below break-even your current sales are.
