CAC Calculator Guide
Calculate your Customer Acquisition Cost in SaasDash.ai with channel-level breakdowns and payback period analysis.
Customer Acquisition Cost (CAC) measures how much you spend to acquire a single paying customer. SaasDash.ai's CAC Calculator gives you a blended CAC plus channel-level breakdowns so you can see which acquisition channels are most efficient.
Plan requirement
The CAC Calculator is available on Starter, Growth, and Scale plans.
What Is CAC?
CAC = Total Sales & Marketing Spend / New Customers Acquired
If you spent $10,000 on marketing last month and acquired 50 new customers, your CAC is $200.
Using the Calculator
Navigate to CAC Calculator
Go to Acquisition > CAC Calculator in the sidebar.
Enter your total spend
Input your total sales and marketing spend for the period. Include ad spend, sales team salaries, tools, content production, and any other acquisition-related costs.
Enter new customers
The calculator pulls your "new customers per month" from your latest metric snapshot, or you can override it manually.
Add channel breakdowns (optional)
Break down your spend by channel to see per-channel CAC. Common channels: paid ads, organic/SEO, referrals, outbound sales, partnerships.
Key Metrics Calculated
The CAC Calculator produces:
- Blended CAC — your overall cost per customer
- CAC by channel — cost per customer for each acquisition channel
- CAC:LTV ratio — how your acquisition cost compares to customer lifetime value
- CAC payback period — months to recoup acquisition cost from the customer's revenue
Healthy Benchmarks
| Metric | Healthy Range | Warning |
|---|---|---|
| CAC:LTV ratio | 1:3 or better | Below 1:1 means you lose money on each customer |
| CAC payback | Under 12 months | Over 18 months strains cash flow |
| Blended CAC | Depends on ARPA | Should be well below 12-month revenue |
Combine with Growth Ceiling
Your Growth Ceiling tells you the maximum customers you can sustain. Your CAC tells you how much it costs to reach them. Together, they answer: "Can I profitably reach my ceiling?"
Improving Your CAC
If your CAC is too high:
- Double down on efficient channels — if organic converts at $50 CAC and paid at $300, invest more in content
- Improve conversion rates — a better landing page or sales process means more customers from the same spend
- Reduce sales cycle — faster deals mean lower cost per deal
- Leverage referrals — referred customers typically have near-zero CAC
