Calculate How Many Units Must Sell Before This Business Turns a Profit
The break-even point answers one question: at what sales volume does this business cover all its costs? Most business owners calculate it once, at launch, then never update it. Costs rise, product lines expand, new staff get hired. The break-even point shifts. Nobody notices until cash feels chronically short despite sales that look adequate. This book is for operators who want to use break-even as a live decision tool, not a launch formality.
This book was originally written in Bahasa Indonesia for Indonesian operators. Examples, regulations, currency (Rupiah), and institutional references reflect Indonesian context. The frameworks, diagnostics, ratios, and operator habits described apply broadly to small and mid-sized businesses in other emerging markets and to many developed-market SME settings as well.
The book comes from three separate break-even miscalculations across three different businesses: a product line that looked healthy on monthly revenue reports but had been operating below its own break-even for 18 months while a more profitable line covered its losses silently; a services business that hired permanent staff based on project volume without first calculating how many additional projects were needed to cover the new fixed costs; and a craft workshop that set prices by undercutting competitors without checking whether those prices cleared break-even after all variable costs were counted. Three different industries, one root cause: break-even was not being calculated routinely, and the number was not being used as a decision threshold when it mattered.
What you'll find
- Break-even calculation for single-product, multi-product, and service businesses, including fixed-cost allocation across multiple product lines
- How to update break-even when fixed costs change, and why this review is more important than the original calculation
- Contribution margin analysis: which product lines or sales channels are actually covering their share of fixed costs
- How to use break-even as a threshold for pricing decisions, investment decisions, and new hire decisions
- Sales channel break-even: why the same product sold through different channels can have completely different margin profiles
- Capacity break-even: how to calculate the minimum utilization needed before adding fixed capacity makes financial sense
- Break-even documentation for investor presentations and due diligence review
Who this is for
- Small-business owners who have never calculated how many units they need to sell before the business covers all its costs
- Mid-cap directors managing multiple product lines without knowing which ones are above and which are below their individual break-even points
- Pre-IPO teams that need break-even analysis documented by product line and sales channel for investor review
