Four numbers, four questions — and why the gaps between them matter most
Four terms. Four different numbers. And business owners routinely use them interchangeably — right up until one of those numbers is the one a bank, an accountant or a buyer actually wants to see.
Revenue. Gross profit. Net profit. Cash. Which one actually tells you how the business is doing?
The honest answer: none of them alone. Each one answers a different question, and the gaps between them are often more informative than any single figure.
The short answer
| Term | What it measures | The question it answers |
|---|---|---|
| Revenue | Total sales before any costs | How much did I sell? |
| Gross Profit | Revenue minus the direct cost of what was sold | Am I pricing and sourcing well? |
| Net Profit | Gross profit minus all operating expenses | Is the whole business viable? |
| Cash | Actual money that has moved in and out | Do I have enough available right now? |
Walking through one example, four ways
A business sells $100,000 of product this month. That's revenue.
The stock sold cost $40,000 to buy. Revenue minus that direct cost leaves $60,000 gross profit — the margin on what was actually sold.
Running the business — rent, wages, insurance, marketing — costs $45,000. Gross profit minus those operating costs leaves $15,000 net profit — what the business earned overall for the month.
But $30,000 of the sales haven't been paid yet, the business bought $10,000 of new equipment, and repaid $4,000 of loan principal. The bank balance moved by nowhere near $15,000 — because cash measures something different again: money that has genuinely moved.
Why the gaps matter more than any single number
Revenue vs gross profit reveals whether your pricing and direct costs are under control. High revenue with thin gross profit usually points to a pricing or sourcing problem.
Gross profit vs net profit reveals whether overheads are proportionate. A healthy gross margin eaten up by net profit means the cost of running the business is the issue — not what you sell it for.
Net profit vs cash reveals timing — unpaid invoices, stock, asset purchases, debt repayments and owner withdrawals all explain why profit and cash rarely match.
Which number should you actually watch?
Not one — each serves a different decision:
Use revenue to track growth and sales performance.
Use gross profit to check whether your pricing and direct costs are sustainable.
Use net profit to judge whether the business, as a whole, is genuinely viable.
Use cash to know whether you can actually pay what's due this week.
A business owner who only watches revenue can miss a business quietly losing money. One who only watches cash can miss a business that's profitable but poorly timed. Understanding all four, and where they diverge, is what gives you the full picture.
A quick self-check
Do I know my gross margin as a percentage — not just a dollar figure?
Has the gap between gross profit and net profit been growing or shrinking?
Can I explain, in general terms, why last month's profit and my bank balance don't match?
Which of these four numbers have I actually looked at in the last 30 days?
When should you get professional help?
your gross margin looks thinner than you'd expect for your industry;
the gap between net profit and cash is large and you can't easily explain it;
you want a monthly report that shows all four figures together, rather than piecing them together yourself; or
you're preparing to apply for finance or bring in an investor, and need to present these clearly.
