Break Even Point

Finance · 3 min read

The exact moment your business stops losing money and starts making it. Everything before this is investment. Everything after is profit.

Imagine you start a small bakery. Before you sell a single loaf of bread, you've already spent money. Rent on the storefront: $3,000 a month. An oven: $5,000 (let's spread that over a year, so about $400 a month). Your own salary: $4,000 a month. Insurance, utilities, software: another $600. Total monthly costs before baking anything: $8,000.

These are your fixed costs — they don't change whether you sell zero loaves or a thousand.

Now the bread itself. Each loaf costs you $2 in flour, yeast, packaging, and the bit of electricity it takes to bake. You sell each loaf for $8. So every loaf you sell contributes $6 toward covering those fixed costs ($8 revenue minus $2 variable cost = $6 contribution).

The question: how many loaves do you need to sell each month to cover the $8,000 in fixed costs?

$8,000 fixed costs ÷ $6 contribution per loaf = 1,334 loaves

That's your break-even point. Sell 1,334 loaves in a month and you've broken even — not made any money, but not lost any either. Loaf #1,335 is your first dollar of actual profit.

This number is one of the most useful things you can know about your business. It tells you the floor — the volume below which you're losing money. It tells you whether your pricing makes sense. (If break-even requires you to sell more bread than physically exists in your neighborhood, your prices are too low.) It tells you whether your fixed costs are realistic. (If you'd need a 5,000-loaf month, maybe don't lease the giant storefront.)

Most entrepreneurs never calculate this. They look at total revenue and total expenses at the end of the year and try to figure out if they made money. The break-even calculation reverses the question: what would have to be true for this to work?
