If you ask most business owners how their business is doing, you’ll hear one of two answers:
“We’re busy.”
or
“Turnover is up/down.”
The problem? “Busy” and “turnover” are not the same as “healthy and profitable.”
You can have record sales and still be:
- Losing money,
- Struggling to pay bills, or
- Constantly stressed about cash.
That’s where financial KPIs (Key Performance Indicators) come in. They’re the small set of numbers that actually tell you whether your business is on track – not just in theory, but in day-to-day reality.
In this guide, we’ll walk through five essential financial KPIs every small business should track monthly this financial year:
- Revenue
- Gross Profit & Gross Margin %
- Operating Expenses
- Net Profit
- Cash Balance / Cash Runway
For each one, we’ll unpack:
- What it is
- Why it matters
- How to calculate it
- What “red flags” look like
Then we’ll show you how monthly reporting turns these KPIs from static numbers into powerful decision-making tools – and how you can get them set up for your business.
- Why KPIs (Not Just Turnover) Matter
Think of your business as a car.
- Turnover (revenue) is like your speedometer – it tells you how fast you’re going.
- But you also need:
- A fuel gauge (cash),
- Engine temperature (expenses and profit),
- Warning lights (trends and ratios that show risk).
If you only look at one dial, you can go very fast straight into trouble.
1.1. KPIs turn chaos into clarity
Without KPIs, many owners run on gut feel:
- “I think we’re doing okay.”
- “We’re busy, so things must be fine.”
- “There was money in the bank when I checked last week.”
With a small set of well-chosen KPIs:
- You can see what’s really happening – every month.
- You can pick up issues early: margins shrinking, costs creeping up, cash getting tight.
- You have something solid to base decisions on, not just emotion.
1.2. KPIs help you steer, not just report
KPIs are not just for your accountant, and they’re not just for the bank.
They help you answer practical questions like:
- Can we afford to hire right now?
- Is this big client actually profitable or just keeping us busy?
- Should we increase prices?
- Are we spending too much on overheads?
- How many “slow months” can we survive?
The magic is not in collecting data for the sake of it, but in choosing a few KPIs you track consistently, then using them to steer the business.
Let’s look at the five core ones.
- KPI #1 – Revenue: The Top Line (But Not the Whole Story)
What it is
Revenue is the total amount your business earns from selling products or services before any costs are deducted. It’s also known as sales or turnover.
Why it matters
Revenue tells you:
- Whether the market is buying what you’re selling.
- Whether your marketing and sales activities are working.
- Whether you’re growing, shrinking, or standing still.
If revenue is flat or dropping, you might have a demand problem (pricing, product-market fit, sales process, marketing) that no amount of cost-cutting will fix.
How to calculate it
It’s simple:
Revenue = Total sales for the period (month, quarter, year).
You can split it by:
- Product/service line
- Client type or segment
- Location / branch
- Once-off vs recurring revenue
The more you break it down, the more insight you get.
Red flags
Revenue alone doesn’t tell the whole story, but there are warning signs to watch for:
- Flat or declining revenue for 3–6 months in a row
- Heavy reliance on one or two big clients (concentration risk)
- High revenue growth with no increase in profit (you’re working harder but not earning more)
If you see these, you want to dig deeper – which is where the next KPI comes in.
- KPI #2 – Gross Profit & Gross Margin %: Are Your Sales Actually Worth It?
What it is
Gross profit is:
Gross Profit = Revenue – Direct Costs (Cost of Sales)
Direct costs (or cost of sales) are the costs directly linked to producing or delivering your product/service, such as:
- Stock / inventory
- Materials
- Production labour (sometimes)
- Subcontractors for client work
- Shipping and packaging
Gross margin % shows gross profit as a percentage of revenue:
Gross Margin % = (Gross Profit ÷ Revenue) × 100
Why it matters
You can have great revenue but poor gross margins and still end up broke.
Gross profit and margin tell you:
- Whether your pricing makes sense
- Whether your direct costs are under control
- Whether each sale generates enough to pay overheads and profit
Low margins mean you’re working hard for very little reward. Improving gross margin is often the fastest way to improve profitability without cutting essential overheads.
How to calculate it (simple example)
Imagine this month you:
- Made revenue of R200,000
- Spent R120,000 on direct costs (stock, subcontractors, etc.)
Then:
- Gross Profit = R200,000 – R120,000 = R80,000
- Gross Margin % = R80,000 ÷ R200,000 = 40%
Red flags
Watch out for:
- Gross margin steadily decreasing over several months
- A sudden drop in margin after taking on new products or clients
- Offering discounts or under-pricing to “keep busy”
These can mean:
- Cost of stock or service delivery has increased and you haven’t increased prices
- You’re over-delivering (scope creep) without being paid for it
- You’re giving away too much in discounts
If revenue is okay but profit isn’t, the gross margin is usually where the story starts.
- KPI #3 – Operating Expenses: Is Your Cost Base Under Control?
What it is
Operating expenses (also called overheads) are the costs of running your business that are not directly tied to each individual sale. Examples:
- Rent
- Salaries & admin staff
- Marketing & advertising
- Software subscriptions
- Phone, internet, insurance
- Travel and entertainment
- Accounting, legal, bank charges
These are the “keep the lights on” costs.
Why it matters
Even with good revenue and healthy gross margins, bloated overheads can eat your profit.
Tracking operating expenses helps you:
- See whether your cost base is growing faster than your sales
- Spot subscriptions and services you’re not using
- Make informed decisions about hiring, marketing spend, and other overheads
You don’t necessarily want the lowest expenses – you want the right expenses for the level and type of business you’re running.
How to calculate it
For a given period (e.g. month):
Operating Expenses = Sum of all overhead categories (excluding cost of sales, tax, interest, etc.)
You can break it down into:
- Staff expenses
- Premises
- Marketing
- Software & tools
- Admin & professional services
Red flags
- Operating expenses increase consistently while revenue is flat or declining
- One category suddenly spikes (e.g. marketing spend with no return, runaway staff costs)
- Owner draws far more than the business can support sustainably
If your expenses creep up quietly, your profit can evaporate even when sales look fine.
- KPI #4 – Net Profit: The Real Score
What it is
Net profit is what’s left after all costs:
Net Profit (before tax) = Gross Profit – Operating Expenses
This is the money your business actually generates from its operations, before tax. You can also look at Net Profit %:
Net Profit % = (Net Profit ÷ Revenue) × 100
Why it matters
Net profit is the answer to:
“Is all of this effort, stress and risk actually worth it?”
It’s what:
- Allows you to reinvest in the business
- Enables you to build cash reserves
- Ultimately pays you as the owner
Tracking net profit monthly:
- Shows you whether your year is on track – not just at year-end
- Highlights combinations of problems (e.g. margins dropping and expenses creeping up)
- Helps you see whether growth is profitable growth, not just more work
How to calculate it (simple example)
Continuing earlier:
- Revenue: R200,000
- Direct costs: R120,000 → Gross profit: R80,000
- Operating expenses: R50,000
Then:
- Net Profit (before tax) = R80,000 – R50,000 = R30,000
- Net Profit % = R30,000 ÷ R200,000 = 15%
Red flags
- Net profit is consistently below your target or below market norms for your industry
- Profits swing wildly from month to month with no clear explanations
- Revenue grows but net profit doesn’t (or even shrinks)
Net profit is a symptom. If it doesn’t look good, you need to go back and examine:
- Revenue trends
- Gross margin
- Expenses
The good news? When you track these pieces monthly, you can pinpoint where the problem lies.
- KPI #5 – Cash Balance & Cash Runway: How Long Can You Breathe?
What it is
Cash balance is simply:
How much cash is in your bank account(s) at a given point in time.
Cash runway (or “months of cash”) is:
Cash Runway (months) = Cash Balance ÷ Average Monthly Expenses
It answers the question:
“If no more money came in, how long could we survive at our current spending level?”
Why it matters
Cash is not just “another KPI” – it’s survival.
You can:
- Be profitable on paper and still run out of cash.
- Have big revenue months but get squeezed if customers pay late.
- Get caught by VAT, PAYE, or income tax when you’ve spent the cash you should have set aside.
Tracking cash balance and runway helps you:
- See danger coming before the bank balance hits zero
- Decide whether you can afford to invest or need to hold back
- Sleep at night knowing you have a buffer
How to calculate it
- Note your cash in all business accounts (exclude personal accounts):
- e.g. Total cash = R120,000
- Work out your average monthly operating expenses (and possibly loan repayments), say over last 3–6 months.
- e.g. Monthly expenses = R60,000
- Then:
Cash Runway = R120,000 ÷ R60,000 = 2 months
This means: if all income stopped tomorrow and you kept spending as usual, you could last roughly 2 months.
Red flags
- Less than 1–2 months of expenses in cash, especially in a volatile business
- Constantly dipping into personal funds or overdrafts to cover short-term gaps
- Paying tax late because the cash “wasn’t set aside”
Healthy businesses typically aim for at least 1–3 months of runway (more in high-risk industries). Your ideal buffer depends on your risk tolerance and how predictable your cash flows are.
- How Monthly Reporting Turns KPIs Into Action
KPIs are only powerful if you see them regularly and use them to drive decisions.
Looking at them once a year – when your accountant sends annual financials – is like checking your car’s speed, fuel and engine temperature only when you reach your destination.
7.1. What monthly reporting actually means
Monthly reporting means:
- You receive a simple, consistent set of reports every month, usually including:
- Profit & loss (income statement)
- Balance sheet
- Cash movement summary
- KPI dashboard (the 5 KPIs we’ve discussed)
- You compare:
- Actual vs budget
- This month vs previous months
- This year vs last year
This turns the 5 KPIs into a dashboard, not just numbers on a spreadsheet.
7.2. Why monthly (not quarterly or yearly)?
Monthly is frequent enough to:
- Catch problems early, while they’re small
- See trends – not just spikes
- Build habits: you know you’ll review the numbers every month
Quarterly can work in some cases, but for most small businesses, three months is more than enough time to drift badly off course.
Yearly is simply too late. By then:
- You can’t change what’s already happened
- You’ve lost the opportunity to steer mid-flight
- And you’re often shocked by tax and profit figures
7.3. How KPIs change your conversations and decisions
With monthly KPIs, your conversations shift from:
- “I feel like things are tough.”
- “It seems like profits are okay.”
To:
- “Revenue is up 12% on last year, but gross margin has dropped 4 points – let’s talk pricing and costs.”
- “Operating expenses have crept up 18% in six months. Where exactly is that coming from?”
- “Cash runway is down to 1 month – we need to slow spending or speed up collections.”
You stop flying blind and start steering with your eyes open.
- Putting It All Together – And Getting Help
To recap, the five core financial KPIs you should track this financial year are:
- Revenue – Are we selling enough?
- Gross Profit & Margin % – Are our sales actually profitable?
- Operating Expenses – Is our cost base under control?
- Net Profit – Is the business truly rewarding our effort and risk?
- Cash Balance & Runway – How long can we keep going if things wobble?
You don’t need a massive finance department to track these. But you do need:
- Decent bookkeeping (up to date, not six months behind)
- A simple monthly reporting rhythm
- Someone who can help you interpret the numbers and act on them
