The KPIs every online coach should track

The six numbers that tell you whether your coaching business is working, and how often to look at each one.

Most coaches know roughly what came in last month and have no idea whether that is better or worse than the month before. There is no shortage of numbers available — your platform reports some, your payment processor reports others, Instagram reports a great many — and none of it adds up to a picture, because nobody wrote anything down.

You do not need a dashboard. You need about six numbers, checked on the right cycle, recorded somewhere you can compare them.

Followers and website traffic are not KPIs

A key performance indicator is a number that changes what you do. If a figure goes up or down and your week looks identical either way, it is not a KPI — it is trivia you have taught yourself to feel something about.

Follower count fails this test for almost every solo coach. So does website traffic, video views, email list size and the number of people who opened your last newsletter. They are all real measurements of real things. The problem is what sits between them and your income: a coach with 30 clients does not have a reach problem, and doubling reach would not change the roster, because the roster is limited by how many people you can coach properly.

Audience numbers start mattering when they are the actual constraint — when you have space for eight more clients, you are converting enquiries at a normal rate, and there simply are not enough enquiries. Until then, tracking them daily is a way of feeling busy about your business without doing anything to it.

The other reason to leave them out is that a metric list you actually maintain has to be short. Twelve numbers is a spreadsheet you will fill in twice and abandon. Six is a ten-minute job once a month, and a list you keep for two years is worth far more than a comprehensive one you keep for two months, because the whole value is in the trend.

The six numbers worth tracking

These six cover the three things that can go wrong in a coaching business: not enough money coming in, not enough clients coming in, and clients leaving faster than you replace them. Each one has a reading that should make you do something specific.

Number
NumberWhat it tells youHow oftenWhat a bad reading means you do
Monthly recurring revenueWhat the business earns in a normal month, ignoring one-offsMonthlyTwo flat or falling months: work out whether it is churn, price or intake, then fix that one thing
Active clients vs capacityWhether you have room to sell, or are already over the lineMonthlyOver capacity: stop selling and fix delivery. Well under: your problem is intake, not service
ChurnThe share of clients who left this monthMonthlyAbove your normal range two months running: go and ask the leavers why
Average revenue per clientWhether you are growing by adding work or by adding valueQuarterlyFalling while client count rises: you are working more for the same money — look at price and tiers
Enquiry-to-client conversionWhether your problem is leads or the sales conversationMonthlyLow with plenty of enquiries: fix the call and the offer, not the marketing
Check-in completionWhether clients are still engaged, before they cancelWeeklyAny client trending down: contact that client this week

Five of the six move on a monthly cycle. Only the last one is worth looking at weekly, and it is the only one that is about individual clients rather than the business as a whole.

The three money numbers

Monthly recurring revenue is the total your active subscriptions bill in a normal month. It is not last month's bank deposit, which includes upfront payments, one-off sales and whatever refunded. The point of recurring revenue is that it is the figure you can plan on: if nobody joins and nobody leaves, that is what next month looks like.

Normalise the billing cycles or the number lies. A client billed weekly is not a quarter of a monthly client, and a client who paid for a year in January is not $2,400 of January. Convert everything to a monthly equivalent — a weekly plan counts as roughly 4.3 payments a month, an annual plan as one twelfth — and the number becomes comparable month to month.

Average revenue per client is recurring revenue divided by active clients. It is the number that tells you which kind of growth you are having. Revenue up and average revenue per client flat means you grew by taking on more work. Revenue up and average revenue per client up means you grew by being worth more, which is the only kind of growth that survives a full roster. Watch it quarterly — it moves too slowly to be worth a monthly look, and it drops the month you take on two clients at a discount, which tells you nothing.

Enquiry-to-client conversion is how many of the people who asked about coaching became clients. Count enquiries the same way every month or the number is meaningless: pick a definition — someone who asked about working with you, in any channel — and hold it. The value of this one is diagnostic. If ten people ask and one signs, more marketing will get you two, and a better discovery call might get you four out of the same ten. Coaches almost always assume they have a lead problem when the numbers say they have a conversion problem.

The two roster numbers

Active clients against capacity is two numbers held together, and the second one is the one coaches never write down. Capacity is how many clients you can coach at the standard you want to be known for — not how many logins you could issue. For full-service online coaching most independent coaches land somewhere between 30 and 45, and what actually breaks first is usually the admin rather than the coaching.

Write your capacity number down once, honestly, and then track the roster against it. Over the line, the correct action is to stop selling — not to sell harder while quality slides, which is the standard route to burning out and losing the clients you already have. A long way under it, with revenue you are unhappy with, means intake is the problem and there is no point optimising delivery.

Wanting more revenue than a full roster can produce is a third case, and it is not a tracking problem at all. Scaling past your own capacity means changing what you sell, not squeezing another six clients into the same week.

Churn is the share of clients who left during the month. It belongs on the list because it is the only number that tells you your business is leaking while every other figure still looks fine — revenue lags churn by a month or two, so by the time the money moves you have lost the quarter. Work it out the same way every month; how to calculate client churn rate covers the formula and what a healthy figure looks like.

What the number cannot tell you is why. That answer only comes from asking the people who left, and the reasons are more consistent than most coaches expect — why clients quit covers the common ones, and the retention levers covers what actually moves the figure. Two months above your normal range is the trigger to go and have those conversations.

The delivery number

The five above describe the business. None of them tells you whether the coaching is landing, and you will find that out from the money three months too late.

Pick one measure of whether clients are still doing the thing. Check-in completion is the usual choice: the share of scheduled check-ins that were actually submitted. It works because it is early, it is per client, and it is unambiguous. A client who has skipped two check-ins has not decided to leave yet, but they have stopped participating, and that is the point at which a message still changes the outcome.

Workout completion against what you scheduled does the same job and suits coaches whose service is mostly training. Either is fine. Tracking both is worse than tracking one, because you will end up watching neither.

This is the only weekly number, and you look at it differently from the others — not as a roster average but as a list of names. The average is stable and boring; the individual movements are the whole signal. In practice the weekly job is five minutes: open the list, find anyone who has gone quiet, message them.

Look at a number on the cycle it moves on

Checking a monthly number weekly is not diligence. It is how you end up making decisions based on noise, because a four-week figure sampled every seven days is mostly measuring which week a handful of invoices landed in.

What over-checking actually costs you

The damage is real. A coach who looks at revenue every Monday sees it fall, drops the price or launches a discount, and has changed the business in response to a normal fluctuation. The same coach looking monthly would have seen a flat quarter and asked a better question.

The rule is simple: look at a number no more often than the period it is calculated over. Monthly metrics get looked at once a month. Quarterly metrics get looked at once a quarter. The weekly delivery number is the exception because it is not an aggregate — it is a list of clients, and one client going quiet is a signal on day three.

There is a second reason not to look constantly, which is that acting on a number requires you to have decided in advance what a bad reading means. Otherwise you are just reading. That is what the last column of the table is for: decide the action now, while you are calm, so that a bad month produces a specific job rather than a bad mood.

Write them down on the same day every month

This is the single most useful habit in the article, and it is more valuable than any individual metric on the list.

Pick a day — the first of the month, or the first Monday — and record the six numbers in the same place every time. A spreadsheet is fine. A notes file is fine. What matters is that it is the same six numbers, recorded the same way, on a fixed date.

The reason is that none of these numbers means anything on its own. Churn of 6% is neither good nor bad; 6% against your own average of 3% is an emergency and 6% against your own average of 9% is progress. You cannot have that comparison unless somebody wrote down the 3% eleven months ago. Most coaches who "track their numbers" are actually looking at a live figure in an app, which shows them today and nothing else, and they have been doing it for two years without ever being able to answer whether things are improving.

Do not revise a definition mid-record

Keep the definitions stable too. If you change how you count enquiries in March, March is not comparable to February, and you have quietly destroyed the only thing the record was for. Write the definition next to the number the first time and do not revise it.

What your software can and cannot tell you

Some of this you should not be calculating by hand. Recurring revenue, active subscribers and average lifetime value per package are billing facts your payments system already holds — in Fitsly's payments and packages, monthly recurring revenue is reported per package with the billing cycles already normalised, and the coach dashboard reports client growth and workout compliance over the last 30 days against the 30 days before.

What no platform can give you

What no platform can give you is capacity, because that is a judgement about your own standards, and it is half of the most important number on the list. It also cannot tell you your enquiry-to-client conversion unless every enquiry passes through it, which for most coaches it does not — the DMs, the referrals and the gym-floor conversations are all outside the system.

So the monthly record is partly copied and partly counted. That is fine. Ten minutes.

Measurement is not usually the problem

A coach who tracks nothing is not failing because of measurement. They are failing, if they are failing, because clients leave, or too few enquire, or the price is too low for the roster they can hold — and all three of those were true before anyone opened a spreadsheet.

What the six numbers do is tell you which one it is, and stop you from spending six months fixing the wrong thing. That is the entire benefit, and it is a large one. But it is diagnosis, not treatment.

The corollary matters more. If check-in completion is falling, adding a second engagement metric will not raise it. If churn is high, calculating it weekly instead of monthly will not lower it. Every one of these numbers is a prompt to go and do coaching work — write a better check-in, call a client, change a price, cap the roster — and the tracking is only worth the ten minutes if the work follows. A coach with six numbers and no habit of acting on them is in exactly the same position as the coach with none, minus ten minutes a month.

Frequently asked questions

How many KPIs should an online coach track?

Six is plenty for a solo coach: monthly recurring revenue, active clients against capacity, churn, average revenue per client, enquiry-to-client conversion, and one delivery measure such as check-in completion. A shorter list you maintain for two years beats a comprehensive one you abandon after two months, because the value is entirely in comparing a number to your own history.
