How Many Hours a Week Does Music-Teacher Admin Actually Cost You?

An honest calculation of what WhatsApp file-juggling, manual invoicing and scattered tools cost you each week. Three scenarios: solo teacher, small school, mid-size school.

Two years ago I tracked how much time I spent outside lessons on administration. I expected it would be manageable. It was not manageable.

An average of four to six hours per week. Six hours I did not spend teaching, composing, or practising. Six hours I did not have a life.

I was not exceptional. After conversations with Joran (Dijkstra Drumschool, 28 students), Marco (Marco Prij Drum Lessons, 22 students) and a handful of other teachers, it became clear: this is the norm, not the exception.

Let us do the honest calculation.

The total per scenario

Scenario 1: Solo teacher, 25 students

ActivityTime/week
Sending lesson material via WhatsApp45 min
Answering WhatsApp questions25 min
Searching for material you already sent20 min
Manual invoicing30 min
Communicating schedule changes15 min
Tracking student progress (notes, memory)20 min
Total≈ 2h 35min

Two and a half hours per week that you spend on things that are not teaching.

If your hourly rate is €40, this costs you €100 per week. That is €400 per month.

Scenario 2: School with 2–3 teachers, 60–75 students

Now coordination escalates. Teachers coordinate via WhatsApp. Lessons get covered. Parents ask questions that land with you rather than with the teacher.

ActivityTime/week
Own lessons and material2h (see scenario 1 × 2.4)
Coordinating with teachers40 min
Schedule management and cover35 min
Invoicing and payment tracking45 min
Collecting and answering parent contact25 min
Total≈ 4h 25min

Four hours that you as school owner spend keeping the machine running. Without a single new lesson being built.

Scenario 3: School with 4–6 teachers, 120–180 students

At this scale administration is a part-time job.

ActivityTime/week
Teacher coordination and updates1h 30min
Schedule problems and cover1h
Invoicing and payment monitoring1h 30min
Handling student communication45 min
Keeping material and plans in order1h
Total≈ 5h 45min

Almost six hours. If you are lucky you have a part-time assistant. If not, you are doing this alongside teaching.

What this administrative work actually is

This is not laziness or poor planning. These are real tasks that require real time.

Managing material. A lesson with YouTube links, PDFs and GrooveScribe patterns has to live somewhere. If that place is WhatsApp, you have to search every time. No teacher remembers which YouTube link they sent to which student.

Tracking student progress. Who can play which rudiments already? Who has been on the same piece for months? Where did Bram get stuck last week? If this lives in your head, you are using capacity you could have spent on the musical.

Invoicing. Cash payments, tracking transfers, chasing overdue payments. The same cycle every month. The same stress every month.

Communication. Parents ask questions. Students call in sick. Schedules shift. This arrives via WhatsApp, via email, sometimes both. No overview.

What it actually costs you

The hours are one side. The other side is concentration fragmentation.

Every WhatsApp message that arrives while you are doing something else costs you 15 to 20 minutes to get back into flow. If you receive ten per day, you lose two and a half to three hours of fragmented attention every day.

Add to that the evenings. Half ten at night. The morning before your first lesson. The moments you thought you were free but opened WhatsApp anyway.

Being a music teacher is a profession. Administration is part of it. But the percentage of time administration consumes is too high for most teachers.

What one hour less per week gives you

One hour per week reclaimed over a year is 52 hours. More than a working week.

What would you do with an extra working week? Build new lessons. Prepare better. Or simply stop on time.

That is not an unattainable wish. Teachers who switched to a platform where lesson material lives in one place, homework is tracked automatically and invoicing disappears from their task list consistently report less admin time.

Not zero. But less.


Joran Dijkstra, one of the first Musicdott users: “I have been using it for one day and can barely picture how I ever did this differently.”

Marco Prij: “It sounds like a cliché but it is true: after a week you already feel like you are doing less juggling.”


Three questions to answer:

  1. How many hours per week do you spend on administration that is not teaching?
  2. What proportion of that is repetitive work a tool could do for you?
  3. What would you do differently with those hours?
