How to Predictably Grow your Monthly Membership EFT* Using Simple Money Math
Jun 02, 2025I love Money Math!
I didn’t love math in school, but when it comes to running a martial arts gym, Money Math is one of the most powerful tools in your arsenal.
Let’s talk about how to make your monthly membership EFT (Electronic Funds Transfer) predictable—and profitable—using a straightforward, math-based approach.
Are You Running Facebook Ads Right Now?
If you’re spending money on ads without a clear idea of your ROI, you’re leaving a lot on the table. Let’s change that.
Step 1. Know Your Goal
👉 Let’s say your goal is to gain 10 full-price members each month.
But wait—don’t forget churn! Let’s assume you lose 5 members each month. That means you actually need 15 new members to net 10.
Step 2. Work Backwards
You’re not going to sign up every lead you get. So let’s break it down using simple Money Math.
Example:
-
Average member pays: $150/month
-
Monthly ad budget: $1,000 on Facebook
(A lot of gym owners get nervous about that amount, but remember: this is an investment, not an expense.) -
Let’s say your ad campaigns generate leads at $15 each (not too bad if your page engagement is decent).
-
$1,000 ÷ $15 = 67 leads.
Step 3. Factor in Lead Quality
We know from experience that 30% of leads are “trash.” They’ll never respond, no matter how many times you call, text, or email. That leaves you with:
-
67 leads x 70% = 47 leads.
Step 4. The No-Show Factor
Now, from those 47 leads, another 30% will flake out before you even get to present your program. That’s just reality.
-
47 x 70% = 33 leads left for presentations.
Step 5. The Sales Close Rate
If your sales team (or you) can close 50% of those presentations, you’ll sign up:
-
33 x 50% = 16 new members.
At $150/month each, that’s:
-
16 x $150 = $2,400 EFT in month one.
You spent $1,000 on ads and made $2,400 in month one. That’s profitable right away—and that’s not even counting the lifetime value of each member.
Step 6. Lifetime Value
If your average member stays for 6 months:
-
$2,400 x 6 = $14,400 in total revenue from those members.
That’s a massive return on your $1,000 ad spend.
Here’s What You Need to Do
1️⃣ Use Proven Facebook Ads that Convert
Run ads that are proven to generate leads at or below $15 each. Don’t neglect your organic content—good organic plus great paid content will supercharge your results.
2️⃣ Build a Solid Appointment-Setting System
Hire and train an appointment setter who’s relentless—text, call, email, voicemail, you name it!
Remember:
✅ 30% of leads are trash—ignore them.
✅ Of the remaining 70%, another 30% may no-show—factor that in.
✅ Make sure your appointment setter is consistent with follow-ups.
💡 Pro Tip: Alan is crushing it with video text reminders—those get amazing responses!
3️⃣ Improve Your Sales Close Rate
If you’re not closing at least 50% of your presentations, you’ve got work to do. Train your staff to confidently close sales and bring that percentage up.
It’s All About Money Math!
When you boil it down, your predictable monthly growth is just a math problem:
-
Attract leads.
-
Get leads to show up.
-
Close the sale.
That’s how you grow your monthly membership EFT predictably and profitably.
