If you’re already pulling $20K to $30K a month as a coach, it can feel like you made it. Then you hit a wall. Most coaches plateau right there for years, because getting to seven figures is a different game with different skills and different strategies.

What breaks the plateau is visibility. To scale a coaching business past seven figures, you need to know your numbers cold. At High Impact Coaching we’ve helped over 50 coaches scale past the million dollar mark, and it always comes down to the same seven.

The 7 numbers you need to scale a coaching business:

  • Cost per acquisition (CPA)
  • Incremental cost of goods sold (COGS)
  • Back end conversion rate
  • Churn rate
  • Average monthly retention
  • Lifetime value (LTV)
  • Return on invested capital (ROIC)

Once you can see all seven, scaling stops being a mystery and starts being math. Here’s each one, how to calculate it, and why it matters.

1. Cost per acquisition (CPA)

Cost per acquisition is what it costs you to land one new client. It’s simple to track if you run paid ads. If you don’t, you still need it, you just calculate it from time and team pay instead.

Two ways to work it out:

  • If you pay a team: add up base pay, hourly cost, cost per booked call, and cost per enrollment. When we ran ours for organic, it came to roughly $1,200 to $1,500 per client.
  • If it’s all you: count your hours, then put a real hourly rate on your time.

Here’s why the hourly rate matters. Say your income goal puts your time at $400 an hour, and it takes you 5 hours to land a client:

  • 5 hours × $400 = $2,500 of your time per client
  • Pay someone $50 an hour to do the same job and it costs you a fraction of that

That gap is the whole reason to know the number.

2. Incremental cost of goods sold (COGS)

Incremental COGS is what it costs to deliver to one more client, on top of your fixed costs. Forget salaries and retainers for a second and ask: if I added one client tomorrow, what would serving them actually cost?

Count the things that scale with each new client:

  • Your hours, or your coaches’ time, to deliver
  • Anything you farm out (every Launch client goes through a breakthrough session)
  • Per-client event costs (every Accelerator client comes to a live event)

You should know your number per client the same way we know ours.

3. Back end conversion rate

Back end conversion is the percentage of front end clients who move into your back end program.

Say 10 people go through your 8 or 12 week front end and 30% continue. That’s about 3 new recurring clients a month. Some months two, some months five. The average is what you build forecasts on.

4. Churn rate

Churn rate is how many people leave your back end in a month, divided by how many were in it. Lose 2 out of 20 and your churn is 10%.

If people are leaving, churn tells you something needs fixing. Two rules for reading it:

  • Track it across the whole year, not one month
  • Expect a January spike right after the holidays, so one ugly month doesn’t scare you off the trend

5. Average monthly retention

Average monthly retention is how long a client stays with you, and it falls straight out of churn. Take 100 and divide it by your churn rate:

  • 10% churn = about 10 months
  • 5% churn = about 20 months
  • 4% churn = about 25 months

That number drives everything downstream, including the big one coming next.

6. Lifetime value (LTV)

Lifetime value is what one client is worth to you over the whole time they stay. You get it from four numbers you already have: your front end price, the percentage who move to the back end, your retention, and your conversion.

Picture an $8K front end, a quarter of those clients moving into a $2K a month back end, and them staying about a year. That’s real money most coaches never add up. It isn’t a one step figure, but once you have it, the last number does the magic.

7. Return on invested capital (ROIC)

ROIC is your lifetime value divided by your cost per acquisition. It tells you what every dollar you put into getting clients turns into.

  • LTV of $21,000 ÷ CPA of $1,000 = $21 back for every $1 in

If you handed me a dollar and I handed you back a twenty, how many times would you do it? You’d never stop. That’s a business that scales.

The takeaway

Cost per acquisition, incremental COGS, back end conversion, churn, average monthly retention, lifetime value, and return on invested capital. Get visibility on all seven and you always know exactly where to focus and what to fix. That’s how scaling a coaching business past seven figures stops being a guessing game.

Frequently asked questions

What numbers do I need to scale a coaching business?

The seven that matter most are cost per acquisition, incremental cost of goods sold, back end conversion rate, churn rate, average monthly retention, lifetime value, and return on invested capital. Together they show you what it costs to get and keep a client and what that client is worth.

How do I calculate cost per acquisition without running ads?

Add up what you pay your team per client, or if it’s all you, count your hours and put a real hourly rate on your time. If landing a client takes 5 hours and your time is worth $400 an hour, your cost per acquisition is $2,500.

What is a good churn rate for a coaching program?

Lower is better. A 5% monthly churn means clients stay about 20 months on average, while 10% means about 10 months. Track it across the year, since one high month right after the holidays can skew a single reading.
