The hidden costs of online coaching, and how to avoid them

Ask a coach what their software costs and they will tell you the number on the sticker: £30 a month, $50, whatever the plan page said when they signed up. That number is rarely more than half the bill. The rest arrives later, one reasonable-looking decision at a time, until the tools are eating a day of client revenue every month.

This is your total bill — the whole ledger, not just the software line. It is the companion to the model-by-model comparison of what coaching software charges: that post compares pricing structures; this one adds up everything the structure hides.

Cost one: the nutrition add-on

The classic. The base plan handles workouts; nutrition arrives as a module. Trainerize's Advanced Nutrition add-on, for instance, runs $20 to $45 a month on top of the base plan — priced, like most add-ons, off the page you compare on. It is rarely flagged on the main pricing page, because the main pricing page is designed to be comparable, and the add-on is where the comparison dies.

If you coach food at all — and most coaches eventually do — the honest comparison price is base plus nutrition from day one. A platform where nutrition is part of the base rather than a bolt-on is not "also fine"; it is a different total, permanently.

Cost two: the payment percentage

Most platforms now process payments, and they take a slice for it — on top of card processing, sometimes instead of it, always worth reading twice. The arithmetic of which structure wins at which volume is worked through properly in the cost comparison; the rule of thumb is that percentage pricing bundles processing into one number while subscriptions-plus-percentages stack two.

The percentages also differ in what they are for. A fee that includes card processing is a fee against one bill. A fee on top of processing is two fees wearing one number, which is how a plan that looked cheap stops being it.

Cost three: per-client pricing

Some platforms charge by the roster: a lower rate for 10 clients, a higher tier at 25, another at 50. It looks gentle until you notice what it actually taxes — growth. Your 26th client does not cost you more time in any interesting way, but the platform bill jumps a tier the month they sign up.

The mental test: does this cost scale with your revenue or with your client count? Revenue-linked costs self-fund. Client-count-linked costs fire before the new client has paid you anything, which is the wrong order for a young business.

Cost four: the quiet month

The most expensive month of software is the one where you earned nothing — holiday, illness, a December like every December — and the subscription charged you anyway. Twelve of those months at £40 is £480 out of the business before a single session is sold. The asymmetry is the whole point: subscriptions are a fixed cost against income that moves.

It is also the quiet argument for transaction pricing, stated plainly because we use it: NForge charges nothing in a month where nothing moves, 7.9% only when clients pay. If you earn nothing in a month, the software bill is zero, which is the only definition of "scaling with your business" that survives contact with an actual business.

Cost five: the tool you forgot to cancel

The one nobody counts because nobody can see it: the scheduling tool from 2023, the video subscription you replaced but never removed the card for, the form tool with one client still on it. Most coaches' real stacks run at least one or two subscriptions deeper than the one they can name off the top of their head. The audit takes twenty minutes: card statement, one evening, cancel everything that is not load-bearing. Twenty minutes for a bill that shrinks every month after is the best trade you will make this week.

The workbench test

Strip it back to what the job actually needs: programme building and delivery, client management, payments that collect themselves, classes if you run them, nutrition if you coach it. Every tool in your stack should map to a line in that sentence. Everything else — the analytics suite, the fourth messaging app, the funnel builder — is a cost looking for a justification, and finding it, monthly.

The platforms that look expensive at first glance and cheap by month six are the ones with the add-ons, the percentages and the tiers. The ones that look strange and end up cheap are the ones with a single number. Compare the totals, not the stickers, and do the maths on your quiet month, not your best one — the quiet month is the honest one.

The online-coaching cost ledger, compressed

• Base subscription: the sticker, and the smallest part
• Nutrition or feature add-ons: $20–45/month each, the classic multiplier
• Payment fees: on top of processing or bundled into it — read which
• Per-client tiers: a tax on growth, paid before new revenue arrives
• Quiet months: fixed costs against no income, £480+/year at £40/month
• Forgotten tools: more subscriptions than the ones you can name

Add yours up before the next renewal date. If the total is under 10% of revenue and nothing nags, keep it — cheap is not the goal, predictable is. But if you flinched at the sum, that flinch is data, and there are ways to run the whole job where the bill is one line that only moves when you do.
