What break-even analysis tells you

Your break-even point is the moment your total revenue exactly equals your total costs — no profit, no loss. Every unit you sell after that point contributes directly to profit. It's one of the first numbers we help clients establish, because it turns "is my pricing sustainable?" from a guess into a calculation.

The core formula Break-even units  =  Fixed costs  ÷  (Price per unit − Variable cost per unit)

The three numbers behind the formula

  • Fixed costs — expenses that stay the same regardless of how much you sell, such as rent, insurance, core salaries and software subscriptions.
  • Price per unit — what a customer pays for one unit of your product or service.
  • Variable cost per unit — costs that rise and fall directly with sales volume, such as materials, packaging, freight or sales commission.

Price minus variable cost is your contribution margin — the amount each sale contributes toward covering fixed costs, and then profit.

Worked example

Melbourne café roasting and selling bagged coffee: Fixed costs of $8,000/month (rent, wages, insurance, subscriptions), a retail price of $65/unit, and a variable cost of $24/unit.

Contribution margin = $65 − $24 = $41
Break-even units = $8,000 ÷ $41 = 195.1, rounded up to 196 units/month
Break-even revenue = 195.1 × $65 ≈ $12,684/month

How to use the results

01

Sense-check feasibility

Compare the break-even units to what your market and current capacity can realistically absorb.

02

Test the levers

Use the scenario chips to see how a price rise, a cheaper supplier or a smaller lease changes the outcome.

03

Set sales targets

Turn the monthly figure into a weekly or daily target your team can track against.

A few important caveats

  • This is a single-product model. If you sell several products or services at different margins, you'll get a more accurate figure from a gross-profit break-even calculation — ask us and we'll run it for you.
  • It doesn't account for tax, loan repayments, owner drawings or seasonal swings in demand — all of which we factor in when we prepare a full cash flow forecast for clients.
  • Treat the output as a planning guide, not a guarantee — real-world costs shift, so we recommend revisiting this quarterly or whenever a major cost changes.
