Free tool for online fitness coaches
Online coaching client capacity and income calculator
Hours a week = clients × (check-in minutes + admin minutes per client) ÷ 60, and your client limit = hours available × 60 ÷ minutes per client, rounded down. In the example, 25 clients at 20 minutes of check-in and 10 minutes of admin each take 12.5 hours a week; with 15 hours available the limit is 30 clients. At $200 a month each, 25 clients bring $5,000 a month, which is $92.31 per hour of client work, and 30 clients would bring $6,000.

Example scenarios
Three sets of example inputs worked through the same formulas as the calculator above. They are illustrations, not averages or statistics.
| Scenario | Inputs | Hours a week on check-ins | Client limit at your hours | Monthly revenue | Revenue per hour of client work |
|---|---|---|---|---|---|
| Low | 12 clients, 25 min check-in + 10 min admin each, 10 h a week, $150 a month | 7 | 17 | $1,800 | $59.34 |
| Typical | 25 clients, 20 min check-in + 10 min admin each, 15 h a week, $200 a month | 12.5 | 30 | $5,000 | $92.31 |
| High | 40 clients, 15 min check-in + 10 min admin each, 20 h a week, $300 a month | 16.67 | 48 | $12,000 | $166.15 |
Method: Hours a week = clients × (check-in minutes + admin minutes per client) ÷ 60; client limit = hours available × 60 ÷ minutes per client, rounded down; monthly revenue = clients × monthly fee; revenue per hour of client work = monthly revenue ÷ (hours a week × 52 ÷ 12). Figures checked against the same formulas on 2026-11-11.
How the calculator works
Online coaching time grows with every client, mostly through the weekly check-in: reading the form, looking at the numbers and photos, and writing a useful reply. Around that sits admin per client, such as updating a program, answering messages and chasing a late payment. The calculator adds the two per client, multiplies by the number of clients and divides by 60 to get hours a week.
It then divides the hours you are willing to give to client work by the minutes each client needs, which gives the most clients you can serve without working more hours, and multiplies clients by your monthly fee for revenue. Revenue per hour divides monthly revenue by the client hours of an average month (hours a week × 52 ÷ 12).
Worked example
A coach has 25 clients. Each check-in takes 20 minutes and each client needs about 10 more minutes of admin a week, so 30 minutes per client. 25 × 30 = 750 minutes, or 12.5 hours a week. The coach has 15 hours a week for client work, so the limit is 15 × 60 ÷ 30 = 30 clients, and the 25 clients use 83.3% of those hours.
At $200 a month, 25 clients bring 25 × 200 = $5,000. An average month has 12.5 × 52 ÷ 12 = 54.17 hours of client work, so each hour earns 5,000 ÷ 54.17 = $92.31. Filling the five free places would bring 30 × 200 = $6,000 at the same hourly figure.
Measure your own minutes first
The result is only as good as the minutes you type in. For one normal week, write down the start and end time of every check-in reply and every bit of client admin, then divide each total by the number of clients. Guesses tend to be low because small tasks such as a quick voice note or a form fix are easy to forget.
What this tool does not do
It plans hours and revenue for one month and forgets everything when you close the page. It does not count sales calls, content or your own training, so keep those out of the hours you enter. It gives no training, nutrition or health advice. For running the check-ins themselves, the Checkwren template linked below keeps each client's check-ins, training blocks and renewals in one Notion workspace.
Questions
How many clients can an online coach handle?
Divide the hours you have for client work by the minutes each client needs a week. With 15 hours and 30 minutes per client, that is 30 clients.
What counts as admin time per client?
Everything client-specific outside the check-in reply: program updates, messages, scheduling and payment follow-ups.
