Break-Even Calculator
How many units cover your fixed costs, what that is in revenue, how many more it takes to hit a profit target, and how far today's volume sits above the line.
Fixed Costs per Month (rent, salaries, software, anything that does not move with volume)
Price per Unit
Variable Cost per Unit (materials, payment fees, shipping, per unit labour)
Units You Sell Now (optional, for the margin of safety)
Monthly Profit Target (optional)
Values shown are examples. Card processing is a variable cost, so a per transaction fee belongs in the variable line, not the fixed one.

Questions people ask
How is the break-even volume calculated?
The page divides your monthly fixed costs by the contribution margin per unit, which is price per unit minus variable cost per unit, and rounds up to a whole unit. Break-even revenue is that unit count times the price.
What goes in fixed costs and what goes in variable costs?
Fixed costs are the ones that do not move with volume, such as rent, salaries and software. Variable costs rise with each unit sold, such as materials, payment fees, shipping and per unit labour; the page puts card processing in the variable line.
How does the profit target change the result?
The page adds your monthly profit target to fixed costs and divides by the contribution margin, which gives the units and revenue you need to earn that profit.
What is the margin of safety?
It is how far the units you sell now sit above the break-even volume, as a share of current units. A negative figure means current volume is below break-even.
