Know Your Numbers, But Which Ones Exactly?
“Know your numbers.”
If you’re a business owner, you’ve heard this more times than you can count.
From accountants. From mentors. From podcasts. From well-meaning friends.
And while it’s technically good advice, it’s also very unhelpful on its own.
Because most founders don’t struggle with wanting to know their numbers.
They struggle with knowing:
Which numbers actually matter
What those numbers should look like
How often to review them
What to do when they don’t look good
So instead of repeating the cliché, let’s make it useful.
If you focus on just three financial pillars to start, Revenue, Profit and Cash, you’ll be ahead of a lot of business owners.
1. Revenue: The Engine
Revenue is the top line. It tells you whether there is demand for what you sell.
But knowing your revenue doesn’t mean glancing at total sales at the end of the month. It means understanding what’s actually driving it.
Here’s what to actually look at:
Total Revenue (Monthly)
What did you generate this month?
Is it growing, flat, or declining?
How does it compare to your target?
Trends matter more than a single number.
Revenue by Product or Service
What products or services are selling?
What’s underperforming?
Where are your highest margins?
Many businesses are surprised to discover their main offer isn’t actually their most profitable one.
Revenue Per Client or Customer
What’s your average sale value?
Are clients buying once or repeatedly?
Are you relying on a small number of large customers?
Revenue concentration risk is the risk of being overly reliant of one or a few main customers and it’s often invisible until it’s too late.
Revenue Forecast
What’s already contracted?
What’s likely but not guaranteed?
Where are the gaps?
This is about what’s coming. If revenue is weak, your problem is usually strategy, pricing, positioning or sales execution. But revenue alone doesn’t tell you if you have a sustainable business.
That’s where profit comes in.
2. Profit: The Discipline
Revenue is exciting. Profit is disciplined.
You can grow revenue and still feel constant pressure. In fact, that’s very common.
To understand profit properly, look at:
Gross Profit
Revenue minus direct costs (cost of goods sold or direct service delivery costs).
What does it cost me to deliver what I sell?
Is my pricing covering those costs comfortably?
Are margins improving or shrinking?
If your gross margin is tight, scaling may actually increase stress rather than relieve it.
Operating Expenses
Review your:
Wages and contractors
Marketing
Software
Rent
Professional fees
These should be intentional investments, not reactive spending.
Net Profit
What’s left after all expenses.
Ask yourself:
What percentage of revenue is profit?
Is that enough to justify the risk you’re carrying?
Are you paying yourself properly?
Profit is what funds growth, resilience and your personal income.
But here’s where most founders get caught out: They might be profitable and still run out of cash.
3. Cash: The Reality
Cash is the oxygen of your business.
You don’t go out of business purely because of a lack of revenue. You go out of business because of a lack of cash.
To truly “know your numbers,” you must understand:
Cash Balance
How much cash is in the bank right now?
How many months of expenses does that cover?
Cash Flow Timing
When does money come in?
When does it go out?
Are large expenses clustered in certain months?
Profit and cash are not the same thing. You can invoice $100,000 and not see the money for 60 days.
Accounts Receivable
Who owes you money?
How old are those debts?
Are you following up consistently?
Rising receivables are an early warning sign of a cash issue.
Cash Forecast
This is where real clarity comes in.
A simple 3–6 month cash forecast answers:
Will I make payroll?
Can I invest in growth?
When will pressure hit?
Without forecasting, every decision feels reactive. With forecasting, you move from stress to strategy.
Why “Know Your Numbers” Feels So Frustrating
Because most business owners:
Get reports from their accountant that they don’t fully understand
Look at them irregularly
Don’t know what good looks like
Avoid them when things feel tight
Finance then becomes something you react to, rather than something you use to lead.
The shift happens when you stop treating numbers as judgment and start treating them as data.
Numbers aren’t there to shame you. They’re there to inform decisions.
Revenue tells you if the market wants what you’re offering. Profit tells you if your model works. Cash tells you if you can survive and grow.
That’s it.
A Simple Starting Point
If you want something practical, start here each month:
Review your monthly revenue and compare it to target.
Review your gross margin and net profit percentage.
Review your current cash position and a 3-month forecast.
From there, you can go deeper into pricing, cost structures, and forecasting systems.
But don’t overcomplicate the beginning.
The Real Meaning of “Know Your Numbers”
It doesn’t mean memorising every line of your P&L.
It means:
You know where your revenue is coming from.
You understand whether you’re actually making money.
You’re not surprised by cash shortages.
When you know those three things, you’re no longer operating in survival mode.
You move from guessing to leading.
And that’s when financial clarity stops being annoying advice and starts becoming a competitive advantage.
