Executive summary
What this edition covers.
Mixed macro signals — a softer naira, cheaper crude — are exactly when you need to know your margin of safety: how far sales can fall before you hit break-even. This edition explains the formula ((actual sales − break-even sales) ÷ actual sales), why two equally profitable businesses can carry very different risk, and how to monitor your cushion.
Key takeaway
Last week we found the break-even point — the sales level at which a business covers its costs. This week’s question is how far above that line you are sitting. That gap, expressed as a percentage, is your margin of safety: the share by which sales could fall before the business starts to lose money. A wide margin means you can absorb a slow month or a cost shock; a thin one means you are one bad month from red ink. It is the single clearest measure of how much financial risk your business is carrying right now.
