The Margin That Isn't All Take-Home: A STEALTH Conditioning Case Study

Nick Hogan runs STEALTH Conditioning, a strength and conditioning practice, and was one of the first coaches on FitFocus. He ran his own figures through the FitFocus business audit calculator, and it returned an 81 percent net margin. That number is correct. Nick does take that profit home every month. It still isn't the whole story of his fitness business profit margin, because the interesting part is what happens to that money next. Most solo operators are looking at the same gap in their own numbers without noticing it.

$15,000 a month, $2,900 in costs, 81 percent margin

This is the unedited output. Revenue, hard costs, and what's left after the bills are paid.

Line	Amount
Monthly revenue	$15,000
Monthly costs	$2,900
Net profit	$12,100
Net margin	81%

The $2,900 breaks down into a gym licence and floor fee of $1,250, marketing of $750 that now covers the editor who cuts Nick's videos together, software and tech of $800, payment processing of $50, and insurance of $50. All of it is real spend. What's left after those bills, $12,100, is Nick's to take home. That part isn't in dispute.

Gross profit isn't free cash

Nick does take the $12,100 home every month. What the raw margin doesn't show is that a healthy business can't spend all of it as personal income. Some of it has to go back into the business. Tax and super set-asides. New equipment. Software upgrades. Marketing spend to keep growing. A buffer for a slow month. None of that shows up as a cost on the calculator, because it isn't a bill Nick has to pay this month. It's money he chooses not to spend today so the business is still standing next quarter.

An 81 percent margin describes what's left after the bills. It doesn't describe what's actually free to spend, because staying in business means continuing to invest in it.

So the number worth chasing isn't what's left after the bills. It's what's left after the business has taken its share too. Rather than publish a guess as fact, it helps to set the reinvestment assumption yourself and watch the real figure move.

What's the honest margin?

Pick the share of monthly profit a solo operator should hold back for tax, super, equipment, and growth. The reserve comes out of the $12,100 net profit, and the free cash margin is whatever is left measured against the $15,000 of revenue. Here is how three reasonable assumptions land. The estimates below are independent and have not been confirmed by Nick for his own business.

Share held back	Monthly reserve	Free cash per month	Free cash margin
20% (light)	$2,420	$9,680	65%
35% (middle)	$4,235	$7,865	52%
50% (heavy)	$6,050	$6,050	40%

At the middle assumption, holding back 35 percent leaves a $4,235 monthly reserve and $7,865 of genuinely free cash, a 52 percent margin. That's the version Nick could defend to an accountant, an investor, or himself.

A different, more honest 52 percent

Fifty-two percent is still a strong small business. It's just not 81. Push the assumption to its conservative and generous ends and the honest number still sits somewhere between the low-40s and high-60s, nowhere near what the raw calculator prints by default. That's normal. Most solo coaching businesses look like this once ongoing reinvestment has a real number attached, and it doesn't make the business a bad one. It makes the number a real one.

This is the same trap behind most rules of thumb about a healthy profit margin for a fitness business. The headline percentage looks generous until you subtract the parts nobody bills you for. It's worth reading alongside how much of that margin quietly leaks to tools, which is the subject of what your software should cost as a percentage of revenue. FitFocus passes Stripe's standard processing fees through at cost with no platform markup, which is part of how its one flat plan keeps that leak small and predictable as a practice like STEALTH grows.

Run your own numbers through the same two questions

What does the calculator say your margin is, and what does it look like once ongoing reinvestment has a number attached? Every solo coach and personal trainer running their own book should be able to answer both. Run the free business audit, or book a 30-minute demo to see how FitFocus fits the way you already coach.

Revenue, cost, and profit figures are Nick Hogan's own, entered into the FitFocus business audit calculator. The free cash estimates use an independent reinvestment assumption and have not been confirmed by Nick against his own numbers.
