The Maths Most Small Businesses Refuse to Do (And Why It's Costing Them Everything)

I sat with a business owner last month who'd been running her consultancy for six years. Profitable, she said. Growing, she said. Doing well.

Then I asked her one question: "What's your effective hourly rate once you factor in all the unpaid work?"

She didn't know. She'd never calculated it.

So we did it together. Right there. Took about ten minutes.

The number that came out was £14.20 an hour.

She went quiet. Then she said something I've heard dozens of times: "I think I've been lying to myself."

The Numbers You're Avoiding

Most small business owners are excellent at tracking some numbers. Revenue. Maybe expenses. Probably VAT returns because HMRC doesn't give you a choice.

But there's a whole category of calculations that get quietly ignored:

  • True cost per client (including the calls, the revisions, the follow-ups nobody logs)
  • Profit per project (not gross margin — actual profit after your time is costed)
  • Break-even point (not roughly — precisely, including your own wage)
  • Cost of delivery creep (what happens when a £2,000 project becomes £2,800 worth of work)

These aren't complicated sums. They're just uncomfortable ones.

And because they're uncomfortable, they don't get done. So decisions get made on gut feeling, on hope, on what competitors seem to be charging.

What Happens When You Finally Do the Maths

Here's what I've seen happen when business owners actually sit down and work through their real numbers:

1. They stop saying yes to bad-fit clients.

Once you know that a certain type of project costs you money (or earns you less than minimum wage), you stop chasing it. You get selective. That feels scary at first, then liberating.

2. They raise prices — and nothing bad happens.

The fear of raising prices is almost always worse than the reality. Most clients don't blink. Some push back. A few leave — and those are usually the ones you should have filtered out years ago.

3. They stop over-delivering without realising it.

When you can see exactly how much time and money goes into each project, you naturally become more disciplined. Not stingy — just boundaried. You deliver what you promised, brilliantly. And then you stop.

4. They finally pay themselves properly.

This is the big one. So many business owners pay themselves last, pay themselves inconsistently, or pay themselves whatever's left over. Once you've done the real maths, you build your salary into the cost base — not as an afterthought, but as a non-negotiable.

A Simple Exercise You Can Do This Week

Pick your last five completed projects or clients. For each one, calculate:

  1. Total revenue received
  2. Direct costs (subcontractors, materials, software, travel)
  3. Hours spent — all of them, including emails, calls, prep, revisions
  4. Your hourly rate = (Revenue - Direct Costs) ÷ Hours

Don't round up. Don't leave out the awkward bits. Be honest.

If the number that comes out is lower than you'd pay someone else to do the same work, you have a pricing problem.

If it's lower than the minimum wage, you have a business model problem.

Either way, now you know. And knowing is where change starts.

Why This Changes Everything

Getting your numbers right isn't about spreadsheets. It's about power.

When you know exactly what you need to charge to be profitable, you stop apologising for your prices. You stop discounting out of fear. You stop taking on work that drains you.

You start quoting with confidence because you've done the maths. You know what a yes is worth — and what a no protects you from.

This is what separates businesses that grow sustainably from businesses that stay busy but stuck. The maths doesn't lie. And once you've faced it, you can finally make decisions based on reality instead of hope.

The Invitation

If you've been avoiding these calculations, this is your nudge. Not to beat yourself up — but to get clear.

Ten minutes with a spreadsheet could change how you price, how you sell, and how you feel about your business.

Do the maths. Then do something about what you find.
