How the break-even calculator works
The break-even calculator uses three numbers: your fixed costs, your selling price, and your variable cost per unit. Fixed costs are the bills you pay no matter how many (or how few) sales you make. Variable costs move with each sale: materials, packaging, shipping, payment processing fees.
The calculator subtracts variable cost from selling price to get your contribution per unit, the amount each sale actually contributes toward covering your fixed costs. Divide your fixed costs by that contribution and you get the number of units you need to sell before you stop losing money. Multiply by the selling price and you have your break-even revenue.
All figures are per month, matching your fixed cost input. Change any number and the results update immediately.
Why knowing your break-even matters
Most small business owners have a rough sense of what they need to sell to "get by", but rarely have the exact number. That gap is expensive. When you know your break-even point, you can set realistic sales targets, price new products with confidence, and spot quickly whether a slow month is a blip or a structural problem.
It also changes how you think about costs. Every dollar you add to fixed costs raises the number of sales you need to make before you see any profit. Every dollar you cut from variable costs lowers the bar. Those two levers work in opposite directions and both are worth pulling, but you cannot pull them deliberately until you know where you stand.
If you are evaluating a new product line, a price change, or a move to bigger premises, running the numbers through this break-even calculator first takes the guesswork out of the decision.
How to lower your break-even point
There are three ways to reduce the number of sales you need to cover your costs.
Raise the price. Even a small price increase has an outsized effect on contribution margin. If your variable cost is $80 and you lift the price from $200 to $220, your contribution jumps from $120 to $140, almost 17% more per sale. You will break even in fewer units even if nothing else changes.
Cut variable cost. Better supplier terms, fewer returns, more efficient fulfilment. Anything that reduces what you spend per sale widens the gap between price and cost. This is often easier to act on than raising prices, especially in competitive markets.
Cut fixed costs. This is where automation earns its keep. Admin tasks, manual reporting, data entry, follow-up sequences. These are labour costs baked into your fixed overhead. Automating them saves time and cuts the monthly fixed costs you have to cover before you turn a profit. A business spending $2,000 a month on avoidable admin that gets automated away needs to make fewer sales every single month to stay in the black.
For more context on the numbers behind each product or service, the profit margin calculator shows you what percentage of revenue you actually keep. The automation ROI calculator estimates what a workflow automation would save you.
