What is a good LTV:CAC ratio?
A ratio of 3:1 is considered healthy for SaaS and eCommerce. 1:1 implies you are losing money. 5:1 implies you are under-spending on growth and missing market share.
WHAT THIS CALCULATOR IS
This is not a vanity “LTV” number.
This is not a spreadsheet full of assumptions.
This is a profit-based LTV:CAC reality check that tells you whether:
- You’re losing money on each customer
- You’re barely profitable and fragile
- You’re actually in a scalable zone
If you spend on ads, this number decides whether growth is real or fake.
THE PROBLEM THIS CALCULATOR SOLVES
Most brands think they’re profitable because:
- ROAS looks decent
- Revenue is growing
- Cash is coming in
But they’re ignoring the real question:
- “How much profit does a customer generate over their lifetime relative to what it costs to acquire them?”
Without LTV:CAC, you can scale yourself into a cashflow trap.
This tool prevents that
WHAT THIS CALCULATOR ACTUALLY DOES
This calculator turns basic performance inputs into a single operating metric:
LTV:CAC = (True Customer Profit Over Time) / (Cost to Acquire Customer)
It helps you:
- Judge whether your business can scale acquisition
- Set a realistic CAC ceiling
- See if retention and margin are doing their job
- Make decisions about budgets with economic clarity
This is the metric investors, operators, and serious growth teams care about.
HOW THE CALCULATION LOGIC WORKS (TRANSPARENCY)
No black box. The formulas are simple and explicit.
Step 1. Pick Your Business Model
You can calculate LTV in two ways depending on your model:
- DTC / E-commerce
- Uses repeat purchases over time
- SaaS / Subscription
- Uses churn to estimate average lifetime
Step 2. Calculate Lifetime Revenue
For DTC / E-commerce
Lifetime Revenue = AOV × Purchase Frequency (Yearly) × Customer Lifespan (Years)
How to estimate frequency (simple method):
- Total orders (last 365 days) ÷ unique customers (last 365 days)
For SaaS / Subscription
Lifetime Revenue = ARPU ÷ (Monthly Churn Rate %)
Example logic:
- If ARPU is $50 and churn is 5%, lifetime revenue ≈ $50 ÷ 0.05 = $1,000
Step 3. Convert Revenue LTV into True LTV (Profit)
Revenue is not profit. So the calculator applies your gross margin:
- True LTV = Lifetime Revenue × (Gross Margin %)
- This gives the only LTV that matters for scaling.
Step 4. Compute the LTV:CAC Ratio
LTV:CAC = True LTV ÷ CAC
- This produces a clean “worth it or not” number.
Step 5. Verdict Rules
The calculator classifies your ratio:
-
< 1.0x = Unprofitable
You’re losing money per customer. -
1.0x to 3.0x = Caution
Profitable, but tight. Scaling can break the system. -
≥ 3.0x = Scalable
Healthy economics. You have room to scale acquisition.

A ratio is just a diagnosis. The real question is:
If my ratio is weak, what lever should I pull first?
Price?
CAC?
Churn?
Margin?
Retention?
