Do You Understand Compound Interest for Your Coaching Business?

Nov '25 • General

I've been focused on quite a bit of investing recently, both personal and people that insist on acting like I'm a professional and ask for financial advice, which I NEVER give.

But after speaking with a few people who are starting to do really well on Skool this week, a similar pattern emerged, and my favorite way to describe it is to say you're getting compounding interest on your consistent, focused activities.

So, I decided to explain, to myself and share it with you.

I was hired to teach compounding to new financial advisors about 30 years ago, and I can't ever get this out of my head. Let's see if I can make a financial concept clear enough to adapt it to your coaching businesses.

It's a long read, so the

TLDR version: Compounding efforts are cumulative, but you need to actively engage 5 "levers" consistently to make this work.

Honestly, I don't, yet.

First, the classic explanation of compound interest (money version).

Compound interest is often called “the eighth wonder of the world” because it makes money grow exponentially instead of linearly.

The formula is:

A = P × (1 + r)^t

Where:

A = the final amount you have
P = the principal (starting amount)
r = the growth rate per period (usually yearly)
t = the number of time periods (years)

Example with money: You invest $10,000 at 10% annual interest, compounded yearly.

After 1 year: $11,000
After 2 years: $12,100
After 10 years: ≈ $25,937
After 20 years: ≈ $67,275
After 30 years: ≈ $174,494

Notice that in the first 10 years, you roughly 2.6x your money, but in the next 20 years, you go from $25k to $174k. The growth accelerates because you’re now earning interest on your interest (and on the interest on the interest…).

Now, the same formula is applied to growing a coaching business.

A coach’s business compounds in almost the same way, but the variables mean something different:

A = P × (1 + r^t)

P = Your starting number of clients (or starting revenue)
r = Your compounded monthly (or yearly) growth rate coming from multiple levers
t = Time (usually measured in months or years)
A = The size of your business in the future (clients, revenue, impact, freedom)

The magic for coaches is that you can actually achieve a much higher effective “r” (growth rate) than the stock market, because you control several compounding levers at once. The five big compounding levers most coaches ignore.

Client Results → Testimonials & Referrals Better results → happier clients → more 5-star testimonials & case studies → more referrals and social proof → higher conversion rates and more clients without extra ad spend.

2. Client Retention & Ascending Keep a client 24 months instead of 6 months, and they pay acquisition cost once but get 4× the lifetime value. Even better: ascend them into higher-ticket programs.

3. Audience Growth + Authority: Every new follower, email subscriber, or YouTube subscriber is an asset that keeps paying you “interest” forever through future launches and offers.

4. Team & Systems When you hire your first assistant or coach, your personal time frees up → you can serve higher-level clients or create more content → revenue goes up → you can hire more team → even more leverage. Ok, so this isn't my favorite thing to do, but it really works well when done correctly.

5. Offer Improvement & Pricing Power: A tiny price increase (or packaging improvement) applies to every future client forever. Raising your price from $3k → $10k on the same number of clients is an instant ~233% compounding boost. Yes, I've already spoken with many of you, and many of you could double your fees with the right offer.

Real-world coaching example using the formula:

Let’s say you start with:

P = 5 private clients @ $3,000 each = $15,000/month

You work on all five levers and achieve a conservative compounded monthly growth rate of just 8% (r = 0.08). That’s very achievable for a good coach.

A = 15,000 × (1 + 0.08)^t

After 12 months: ≈ $37,000/month
After 24 months: ≈ $94,000/month
After 36 months: ≈ $239,000/month
After 48 months: ≈ $608,000/month
After 60 months (5 years): ≈ $1,540,000 per month

Yes, million-dollar months from a $15k/month start in 5 years — and this has happened for many top coaches (Alex Hormozi, Sam Ovens, and Amy Porterfield, etc.).

Even if you only hit 5% compounded monthly growth (which is very conservative):→ You still go from $15k → ~$180k/month in 5 years.

The key insight?

Money in the bank compounds automatically.

A coaching business only compounds if you deliberately reinvest in those five levers instead of just trading time for money.

Most coaches stay stuck at the dreaming-about-it stage, aiming for $2k months, while others aim for $5k–15k months because they get a few new clients and then coast — their “r” drops to almost 0%.

The coaches who reach 7- and 8-figure businesses treat their businesses exactly like compound interest machines: they obsess over increasing “r” every single month, then let time do the heavy lifting.

Remember:

Your income tomorrow is your habits today, compounded.

Just like money, the earlier and more consistently you increase your growth rate “r”, the less intense you have to work later — because momentum takes over.

P.S. The clarity I've been looking for has come from my ignoring Skool most of the last week.

Significant changes are about to happen.

Have a Blessed Thanksgiving.
