Know Your Breakeven Number

Ask most business owners what their monthly revenue target is, and they'll answer instantly. Ask them what their breakeven point actually is (the exact revenue needed just to cover costs before a single rand of profit is made) and the answer is often a vague guess. That gap is where a lot of financial risk quietly lives.

A tool most businesses skip

Breakeven analysis is one of the simplest financial tools available, yet it's frequently skipped in favour of gut-feel budgeting. Without knowing the true breakeven point, decisions on pricing, hiring, and expansion all get made without a clear picture of the floor beneath the business.

What the numbers actually show

Why accurate cost data matters

A reliable breakeven analysis depends on accurate separation of fixed and variable costs, the same data integrity that underpins correct VAT and income tax reporting to SARS. Businesses with messy, uncategorised expenses in their accounting system struggle to calculate breakeven accurately, and that same mess raises the risk of misstatements in tax submissions. Clean bookkeeping serves compliance and strategy at the same time.

Working out the real breakeven point

Breakeven analysis requires three inputs: total fixed costs (rent, salaries, insurance and other costs that don't change with sales volume), variable cost per unit or per rand of sales, and the selling price. The formula, at its simplest, divides fixed costs by the contribution margin (selling price minus variable cost) to show how many units, or how much revenue, are needed before all costs are covered. Modern cloud accounting platforms can automate much of this once the chart of accounts properly separates fixed from variable costs.

From breakeven to pricing decisions

Once the breakeven point is known, every pricing and cost decision becomes clearer. A price increase's impact on breakeven volume becomes calculable rather than guessed, and a new hire's effect on the fixed cost base, and therefore how much additional revenue is needed to justify it, becomes a concrete number rather than a leap of faith. Breakeven analysis turns abstract anxiety about "making enough money" into a specific, trackable target.

Putting it into practice

  • Separate your costs properly. Review your chart of accounts and clearly classify every expense as fixed or variable.
  • Work out the contribution margin for your core product or service: selling price minus variable cost per unit.
  • Determine your breakeven revenue. Divide total fixed costs by the contribution margin percentage to find the breakeven revenue target.
  • Compare actual revenue against the breakeven point every month, not just at year-end.
  • Re-run the analysis after major changes. Recalculate whenever you hire, change pricing, or take on new fixed costs like additional premises.

Conclusion

The breakeven point is probably the one number in the business that isn't being tracked, and it's worth changing that. Once it's known, pricing, hiring, and growth decisions stop being guesswork and start resting on the real economics of the business.
