March revenue came in at $52,000. Was that good? It depends entirely on what you set it beside. Against February it is up 8.3%. Against last March it is up 11.8%. As part of the last twelve months it moved the total by 1.0%. All three are true, and an owner who sees only one will reach a different conclusion from an owner who sees another.
Most reports choose for you, and they usually choose "versus last month", which is the least reliable of the lot. This piece goes through the comparisons one at a time: what each can tell you, what it cannot, and when to use it. The example throughout is one invented studio, Alturra Studios, with 240 members at $169 a month.
Reading trends in one minute
- Last month is the weakest comparison. It cannot separate real change from the season or from a month simply being longer.
- Last year removes the season. Same month, a year apart, is the honest test of growth for a business with busy and quiet months.
- A trailing window removes the noise. Three months for direction, twelve for size.
- Never judge a part month against a whole one. Set it against the same days of an earlier month.
| The question | The comparison to use | In the example | Watch out for |
|---|---|---|---|
| Are we growing? | same month last year | March: +11.8% | a one-off event in either year |
| Which way are we heading? | last three months against the same three a year ago | $150,000 against $135,000: +11.1% | it lags a sudden change by a month or two |
| How big is the business now? | trailing twelve months | $557,500 | too slow to steer by |
| What changed since last month? | last month, with dues and daily sales split | +$4,000, of which $870 is the calendar | the season and the length of the month |
| Are we on pace this month? | the same days of last month, or a goal for those days | April 1 to 10: −0.1% | dues that bill on fixed dates |
What is the difference between month over month and year over year?
One compares a month with its neighbor. The other compares it with itself a year earlier. For a business with seasons, that is the difference between a comparison that mostly measures the calendar and one that measures the business.
Look at Alturra's first quarter both ways. Month over month it lurches: a big rise in January, a fall in February, a rise again in March. An owner reading only that column would have celebrated in January, worried in February and relaxed in March. Year over year the same three months tell one calm story.
February did not go wrong. February is a short month that follows the year's biggest sign-up month. It was always going to be smaller than January. What the owner needed to know was whether this February beat last February, and it did, by 10.3%.
This is why a revenue goal should start from the same month last year and not from last month. A goal built on January would have set February up to fail.
Why is last month a misleading comparison?
Because three things change between two months, and only one of them is your business. The season changes. The number of days changes. And, sometimes, the studio actually does better or worse. A single percentage adds all three together.
Take the $4,000 by which March beat February and pull it apart. A studio has two kinds of revenue, and they behave differently. Dues are charged per month: a member pays $169 whether the month has 28 days or 31. Everything else, packs, drop-ins, private sessions, retail, is sold per day, so a longer month simply has more selling days in it.
That split is the rule for any two months of different lengths: compare dues as monthly totals, and compare everything else per day. Dividing the whole month's revenue by its days is the common shortcut, and it is wrong for a membership business, because it treats a short month's dues as if they had shrunk. The recurring revenue piece covers the dues side, which is best watched as its own number.
What does trailing twelve months tell you?
How big the business is, with the season taken out. A trailing twelve months is the total of the most recent twelve. Each month you drop the oldest and add the newest. Because the window always holds exactly one January, one July and one of everything else, the busy and quiet months cancel.
The trailing twelve months moves slowly, and that is its job. It will not tell you that last week was poor. It will tell you, without argument, that the studio is larger than it was a year ago, and by how much. Lenders and buyers read it for that reason. For steering, pair it with something quicker: the last three months against the same three a year earlier. For Alturra that is $150,000 against $135,000, up 11.1%, which agrees with the monthly year-over-year readings and confirms that the growth is steady.
The picture also shows your seasons at a glance. Alturra dips in June and July and again in December. Knowing your own shape is what lets you prepare for the busy months before they arrive and stops a normal July from feeling like a decline.
How should you read a month that is not finished?
Against the same days of an earlier month, never against a whole month or a simple share of one. Month-to-date figures are where most false alarms and false comfort come from.
The trap is the proportion. On April 10, ten days in, it seems fair to compare April so far with ten thirty-firsts of March. For a business that sells evenly through the month, it would be. A studio does not. Alturra bills half of its dues on the 1st and half on the 15th, so the first ten days hold half the month's dues and a third of its days.
Compare like with like: the first ten days against the first ten days. Or take the dues out and compare only the part that is sold daily, which is how the daily goal works. Either way, mark the open month as partial wherever it appears. The same discipline applies to rates. A conversion or retention figure for a month still in progress will read low, for the reason set out in the funnel piece: the people in it have not finished deciding. And the retention formula is always read on a closed month.
Why does a big percentage sometimes mean nothing?
Because it is a percentage of a small number. Percentages make small lines look dramatic and large lines look dull. The fix is simple and almost never done: read the dollars beside the percentage, every time.
The same caution applies to counts. If 2 of 6 intro offers converted last month and 4 of 6 this month, conversion "doubled" on the strength of two people. Keep the counts beside the rate, and do not draw conclusions from a base that one sale would move by ten points.
How many months make a trend?
As a working rule: one month is noise, two is a question, three in the same direction is a trend. That is a rule of thumb, not a statistic, and it is deliberately conservative. Acting on a single month means reorganizing the studio in response to weather, a holiday or a teacher's vacation.
Two further tests make a trend believable. It should show up in a comparison that removes the season, so check it year over year. And you should be able to name its cause. A fall you can explain, a class block that ended, a price change, a departure, is one you can act on. A fall you cannot explain needs another month and a closer look before it needs a decision. The piece on numbers that do not match is worth reading first if two of your reports disagree about what the month even was.
What to do this month:
- Take your last closed month. Write down revenue, then the same month a year ago, then the change in dollars and in percent.
- Add the last three months and the same three a year earlier. If the two readings agree, you know your growth rate.
- Split last month into dues and everything else. Divide everything else by the days in the month.
- Find where your reports show the open month, and make sure it is labeled as partial.
- Total the last twelve months. Put the figure somewhere you will see it, and update it monthly.
Where this lives
None of this is hard arithmetic. It is the same arithmetic done the same way every month, which is where a spreadsheet tends to drift. Keeping the comparisons consistent is what Xyzios does. It works with Mindbody and is an approved Mariana Tek integration, and the platform stays your system of record. Its boards read by window, month to date, quarter to date, the last full month and others, and compare a window with the same-length window before it. It keeps open periods apart from closed ones: churn is read on the last closed month, with the current month marked as partial, and conversion cohorts that are still maturing are marked as such. Each location carries a twelve-month revenue trend. Until you set goals, the boards pace against your own trailing performance.
When the dues line is the one heading down, the members behind it are a list: Xyzios flags those whose attendance is slipping against their own pattern and drafts a short save note for the ones at high risk, which waits for your approval. How the save works covers it. From here, a three-month forecast is the same history read forward, and the twelve studio KPIs are the other numbers worth the same treatment.
Start with one closed month and last year's version of it. The churn calculator turns a monthly rate into a year, which is the same idea applied to members, and the two-minute studio check will show which number your studio is missing.
