What matters most
| Priority | How to apply it |

| Downside risk | Mixed product margins require a weighted average. |
| Verification point | Break-even does not include a return for the owner unless entered as a cost or target profit. |
How to use this guide
Use current selling price, variable cost per sale, fixed costs and the same sales period throughout the model. For this page, the comparison is only valid when the monetary basis and timing are consistent.
- Start break even analysis guide by defining the cash-flow decision before entering figures.
- Validate the base case against this page-specific point: Use contribution per unit, not gross revenue.
- Build a realistic downside scenario around this constraint: Mixed product margins require a weighted average.
- Before acting, verify this final check against current statements, contracts or official guidance: Break-even does not include a return for the owner unless entered as a cost or target profit.
Worked example
If fixed costs are $6,000 and contribution is $30 per order, simple break-even is 200 orders before target profit.
What can change the answer
- For break even analysis guide, confirm whether every amount is gross or net and whether GST is included, excluded or not applicable.

Frequently asked questions
What is the break-even formula in units?
Divide fixed costs by contribution per unit, where contribution is selling price minus variable cost. With $6,000 fixed costs and $30 contribution per order, break-even is 200 orders.
What if the selling price is no higher than the variable cost?
There is no positive contribution to cover overhead. Selling more at that price does not reach break-even; the price, variable cost or offer needs to change.
Does reaching break-even pay the owner a profit?
Only if owner remuneration or a target profit has been included in the model. Covering the costs you entered is different from reaching an income target.
