Most business owners I meet can tell me their turnover. Far fewer can tell me their gross margin. And almost none can tell me their cost per lead.
That’s a problem — because profit isn’t made at the top line. It’s built, lever by lever, throughout the business.
In this post, I’m going to walk you through the 12 numbers that matter most in any business. And as we go through them, I’m going to make a distinction that most business owners miss: the difference between a lever — a number you can actively pull to change an outcome — and an outcome — the result of pulling that lever.
It matters because if you focus all your energy on outcomes and ignore the levers, you’ll never know what to change. The numbers are in order, 1–12, as they flow through the business. The label tells you what each one is.
One more thing before we dive in: not every lever applies equally to every business, and not every lever has the same power. A trade business might have very little room to move on average basket size, but huge opportunity in its conversion rate. A service business might have a fixed price list, but enormous leverage in how many leads it generates. Understanding which levers matter most in your business is half the work.
One note: if measuring and managing these numbers feels like a job for someone else as well as you, it’s worth reading honestly about what business coaching costs and the problems to watch out for when hiring a coach before you go looking for help.
The 12 Numbers That Drive Your Business
1. Number of Leads — Lever
This is the very top of the funnel — and it’s the one most business owners feel most emotionally about. Leads are the lifeblood of the business, and generating them consistently is marketing 101. Every business owner should measure this, without exception.
Measure leads from every channel: web enquiries, referrals, telephone, social media, exhibitions, networking. Once you know the number, go deeper — what channels are delivering the best quality leads? Are you tracking cost per lead (marketing spend ÷ number of leads) by channel? If not, start now.
The number of leads is a high-impact lever in most businesses. More leads almost always mean more opportunity — but only if the next lever is in good shape.
Leads can come from
Paid Advertising
Social media
A lead is someone who responds to your marketing efforts, but not all will be genuine Prospects.
2. Prospect Conversion Rate — Lever
Not all leads are created equal. A lead is an expression of interest — a prospect is someone who has taken a genuine step further into your process. Your prospect conversion rate measures how effectively you’re moving leads to that next stage.
Formula: Prospect conversion rate = Number of prospects ÷ Number of leads
If this rate is low, the problem is usually in how you qualify leads, how quickly you follow up, or whether the right people are finding you in the first place. This is a lever you can move — often quickly, and with a big impact downstream.
3. Number of Prospects — Outcome (of #2)
The number of prospects in your pipeline at any time is a direct outcome of how many leads you generate (lever 1) and how well you convert them (lever 2). On its own, it’s a useful indicator of pipeline health — but the way to grow it is to work the levers above it, not to stare at this number.
4. Customer Conversion Rate — Lever
How many of those prospects turn into paying customers? Are you leaving money on the table by not following up properly? Are there gaps in your sales process that allow prospective customers to slip through the net?
Formula: Customer conversion rate = Number of new customers ÷ Number of prospects
The cost to acquire a customer (marketing spend ÷ number of new customers) is one of the most important metrics you can track. It keeps you honest about your marketing spend and allows you to budget realistically for growth. For most professional service businesses, there’s a 1–2 month lag before a new client is profitable — so understanding this number is essential for cash flow planning.
5. Number of New Sales — Outcome (of #4)
Like the number of prospects, the number of new sales is a result — it tells you what happened when you pulled levers 1 through 4. It’s a vital health check, but to change it, go back upstream to leads and conversion rates. That’s where the work is.
Note on repeat business: Many businesses rely heavily on returning clients — subscription models, trade suppliers, service retainers. For these businesses, calculating repeat revenue and churn separately from new business gives a much cleaner view of growth. Treat them as different metrics and focus on them differently.
6. Average Basket / Order / Invoice Value — Lever
There are only two ways to grow revenue: get more customers, or get existing customers to spend more. That’s it. Which makes average order value one of the most underused levers in most businesses.
Formula: Average basket = Total revenue ÷ Number of sales
Beyond the average, look at customer lifetime value and annual customer value. These numbers inform your marketing budget, your pricing strategy, and your long-term planning. If you are in doubt about raising your prices, this article may be worth a read
This lever isn’t equally powerful in every business. A business with a fixed price list has less room to move here than a project-based business with scope to upsell or package services. Know your room.
7. Top Line Revenue — Outcome (of #1–6)
This is the number most of us know. And while it’s important, revenue on its own tells you surprisingly little. Two businesses with the same revenue can have very different levels of profitability depending on how that revenue is made up. A thorough understanding of how your revenue is built — from leads through to average basket value — is what separates a business owner from someone who just has a job.
8. Gross Margin — Lever
In golf they say “drive for show, putt for dough.” In business, margin is the putt. You can have impressive top-line revenue and still be running a loss if your margin is thin.
Gross margin is what’s left after you’ve paid the direct costs of delivering each sale — the costs that go up and down with your volume. Think materials, subcontractors, delivery costs, direct labour on a job. It can and should be expressed as a percentage of revenue.
Important: This is not the same as the gross profit in your accounts. Accountants include fixed costs (wages, rent, insurance) in cost of goods sold to comply with accounting standards. As a business owner, you must keep variable and fixed costs separate. If you mix them, you can’t forecast, you can’t plan, and you can’t price properly.
Gross margin is a highly moveable lever in most businesses — through better buying, smarter pricing, tighter job costing, or reducing waste and rework. It often has the highest impact on net profit of any lever in the business.
9. Gross Profit — Outcome (of #7 and #8)
Formula: Gross Profit = Revenue − Cost of Sale (direct/variable costs only)
Gross profit is what you have left to run the business with — to cover your overheads, wages, and still make a net profit. It’s the direct result of your top-line revenue and your gross margin percentage. Pull the right levers on both, and gross profit grows. Allow either to drift, and you’ll feel it quickly.
10. Overheads — Lever, but largely fixed
Let’s be honest about overheads: for most businesses, most of the time, these costs don’t move much. Rent, rates, insurance, software subscriptions, leases — they tend to stay roughly the same whether you’re busy or quiet. That’s what makes them “overhead.”
But here’s what I’d push back on: overheads are not untouchable. In fact, for some businesses — particularly those where top-line growth is slow or where margins are tight — a review of overheads can be one of the quickest ways to improve the bottom line. Every pound saved here goes straight to net profit.
So yes, they’re largely fixed. No, we don’t include them in cost of sale (that would corrupt your gross margin calculation). But don’t ignore them — review them at least annually. Ask: what are we paying for that we’re not fully using? What contracts are we just rolling over out of habit? Is there a better deal to be had?
In some businesses, this is the first lever worth looking at — particularly in a downturn or a period of restructuring. Just don’t confuse cutting overheads with building a business. It’s a useful fix, not a growth strategy.
11. Wages & Salaries — Lever, worth its own focus
Wages and salaries sit separately from overheads because they deserve their own attention. The payroll is usually the largest single cost in any people-based business, and it’s worth measuring in its own right.
The key ratio to track: wages as a percentage of gross profit (or revenue). This tells you how productive your team is relative to what they cost. If this ratio is creeping up, it’s a sign that either your revenue isn’t growing as fast as your headcount, or your margin is being squeezed.
Like overheads, wages are largely fixed in the short term — you can’t easily halve your team on a slow month. But they’re absolutely worth managing carefully as the business grows. How you and your team use your time has a direct impact on the return you get from your wages bill.
12. Net Profit — Outcome (the one that counts)
Net profit is the figure that really matters. It’s what’s left after everything — revenue earned, costs of delivery, overheads, wages, the lot. This is what funds your growth, your drawings, your future.
Here’s the honest truth though: by the time you see your net profit figure, it’s too late to change it. It’s a lag indicator — it tells you what happened, not what’s happening. That’s why everything above it matters so much. Focus your energy on the levers — leads, conversion rates, average basket, margin, overheads, wages — and net profit becomes the natural result.
So, Where Do You Start?
If you’re new to tracking these numbers, don’t try to measure all 12 at once. Start with the ones that give you the most leverage in your specific business right now.
Not generating enough leads? Start there. Converting well but not growing? Look at average basket and margin. Making good revenue but no profit? Dig into gross margin and overheads. The numbers will tell you where to look — if you’re measuring them.
When I work with clients, this is always one of the first things we get into together. Not because numbers are the most exciting part of running a business, but because without them you’re flying blind. And flying blind is fine — until it isn’t.
