5 Numbers Every Trainer Should Track Every Month
Ask any trainer how business is going and you'll most likely hear “Well… fine, people are coming.” That's a feeling, not an answer. And feelings are misleading: the studio looks packed on Monday evening, yet the month closes with less revenue than the one before. Or the opposite — you worry about a class that is actually your most stable one.
You don't need complex reports or Excel sheets with 40 columns. You need 5 numbers you check once a month — in 10 minutes, over a coffee. They'll tell you which classes to add, which to move, when you're losing clients and how much you're really earning. Here's what they are and how to read them.
1. Class occupancy
What it is: how many of the available spots are actually taken. If a class has 12 spots and 9 people show up on average, occupancy is 75%.
Why it matters: it's the most direct indicator of whether your schedule matches demand. Overall occupancy for the month is useful, but the real value is in the breakdown — by activity type, day and time. It often turns out that Tuesday at 7:00 is half empty, while Thursday at 18:30 has people on the waitlist every single week.
How to read it:
- Above 80% for several weeks in a row — demand exceeds supply. Consider an extra class at the same or an adjacent time slot. If there are also people on the waitlist, the signal is even clearer.
- Below 30% for several weeks in a row — the class isn't working in its current form. Change the time, the format, or merge it with another one.
- Between 50% and 80% — a healthy zone with room to grow.
In Click and Fit, the detailed statistics show occupancy and the number of people waiting for each class by day and time, and the system nudges you on its own: if a class has been full for 4 weeks in a row, you get a suggestion to add more classes; if it's been below 30% occupancy for 4 weeks in a row — a warning.
2. No-show and cancellation rate
What it is: the share of bookings that end up marked “No-show” or cancelled.
Why it matters: high occupancy on paper with lots of no-shows is an illusion. The class looks full in the schedule, but there are fewer people on the mats in reality — while the people on the waitlist stayed at home. Every no-show is also lost revenue, especially if you don't work with prepaid passes.
How to read it: compare the rate month over month. If it's rising, check whether it's concentrated among a few clients or at a specific time (for example, early morning classes). Timely cancellations aren't a problem — they free up a spot. The problem is no-shows without notice.

3. Unique and new clients
What it is: how many different people trained with you this month and how many of them came for the first time.
Why it matters: 200 visits a month can mean 20 people coming 10 times each, or 100 people coming twice each. Those are two completely different businesses with different risks. In the first, losing 3–4 regulars is felt immediately. In the second, the challenge is turning occasional visitors into regulars.
How to read it: the number of new clients shows whether your marketing is working — Instagram, referrals, your Google profile. If you get almost no new clients for several months in a row, your client base will slowly shrink, even if everything looks fine right now, because some people inevitably drop off over time.
4. Revenue — total and by class
What it is: how much you actually earned during the month from the sessions you held — and which classes bring in the most.
Why it matters: not all classes take the same effort, and not all of them bring in the same money. A personal training session at €40 and a group class with 10 people at €12 each take roughly an hour each, but bring in €40 versus €120. Without the numbers, it's easy to spend the most time on what earns you the least.
How to read it:
- Compare it with the previous month, rather than just asking “is it good” in absolute terms.
- Divide revenue by the number of classes held — that gives you the average revenue per class and shows whether it's worth adding more time slots.
- Account for seasonality: December and August are usually weaker, January and September stronger. Once you have the data, also compare with the same month last year.
In Click and Fit, the monthly statistics calculate revenue based on actual attended visits and the price of each activity, and show the percentage change in visits compared to the previous month.
5. Client retention
What it is: how many of your clients keep coming back month after month.
Why it matters: keeping an existing client is far cheaper than finding a new one. A regular client trains more often, buys passes, brings friends and is forgiving when something isn't perfect. If retention drops, no amount of marketing will make up for it for long.
How to calculate it simply: take the unique clients for the month and subtract the new ones — that gives you your returning clients. Compare them with the unique clients from the previous month. For example: last month 60 people trained with you; this month you have 58 unique clients, 10 of whom are new. So 48 out of 60 came back — 80% retention.
How to read it: look at the trend, not at a single month. It also helps to check the list of your most active clients — if one of them suddenly disappears from it, that's a cue for a personal message, not for waiting. In Click and Fit, you'll find the top 10 most active clients for each month right in the statistics.
The 10-minute monthly review
You don't need to analyze everything every day. Once a month, in the first few days of the new month, it's enough to answer 5 questions:
- Which class is the fullest and which is the emptiest? Should I add or move something?
- Is the no-show rate rising? For whom and at what time?
- How many new clients came, and where did they come from?
- How does revenue compare with last month and with the same month last year?
- Which regular clients haven't I seen lately?
Write down your answers and one concrete action for the next month. For example: “I'm adding a second class on Thursday at 19:30” or “I'm messaging the five clients who haven't come in for 3 weeks.” One action a month is enough to see a difference by the end of the year.
Frequently asked questions
I only have a few clients — is it worth tracking numbers? Yes, even more so. With a small client base, every client is a large share of your revenue, and changes show up sooner. Plus, it's easier to build the habit from the very start.
Can I track these numbers in Excel? You can, but only if every booking, cancellation and no-show is entered manually — and that's exactly the part most trainers drop after the first month. When bookings go through a system, the numbers add up on their own.
How often should I check the statistics? Once a month for decisions. If you're testing a new class or a new time slot, check occupancy weekly for the first 4 weeks.
Conclusion
Numbers don't replace a trainer's instinct — they test it. Occupancy, no-shows, new clients, revenue and retention: five numbers, ten minutes a month, and decisions based on facts instead of gut feeling.
