If you don’t know your numbers, scaling is like trying to fill a bathtub with the drain wide open.
But three numbers matter more than any others in your business.
And with just these 3, I can pinpoint exactly what’s blocking your growth…
What are they?
→ 1. Close Rate
→ 2. Lifetime Gross Profit (LTGP)
→ 3. Cost to Acquire Customers (CAC)
You need a pulse on these numbers—monthly at the very least.
Here’s why…
→ 1. Close Rate (%) – Can You Actually Sell?
Formula: Clients Sold / Sales Calls = Close Rate %
🔴 <20% → Lead quality is off, or your sales suck
🟢 >40% → Congrats! But… you might be charging too little
→ 2. Lifetime Gross Profit (LTGP) – The Real Bottom Line
Formula: Lifetime Value (LTV) - Fulfillment Cost - Sales Team = LTGP
LTV alone is a vanity metric.
Profit is what fuels growth. The more you keep, the more you can reinvest and scale.
→ 3. Cost to Acquire Customers (CAC) – The “How Much Are You Really Paying?” Number
Formula: Marketing Spend / Clients Sold = CAC
Most founders know how much they’re throwing at ads… but not how much it actually costs to get a customer.
Now, here’s Where the Magic Happens…
If you know LTGP and CAC, you unlock The Mother Ratio:
LTGP / CAC = The Truth Serum
⛔ <1.0 → You’re losing money on every customer
⚠️ 1.0 to 2.0 → You’re treading water, but scaling will sink you
🚀 3.0+ → Ready for scale - keep spending that marketing moolah
If your ratio is <2.0…
- your profits per customer are too low (LTGP needs a boost)
OR
- your marketing is leaking money (CAC is too high)
Simple rule: Divide your LTGP by 3, and that’s your ideal CAC.
But please, don’t keep stuffing Zuckerberg’s and Elon’s pockets without knowing if it’s actually making you money.
Track these:
✅ Close Rate
✅ LTGP
✅ CAC
Know them. Love them. Use them.
