Fun_Ostrich_5521 The 2025 Guide to LTV:CAC Ratios in SaaS
Hey SaaS builders — whether you're deep in growth mode or still figuring out your numbers, let’s talk about something that comes up a lot: the LTV to CAC ratio.
So what’s all the fuss about?
- LTV (Customer Lifetime Value): How much a customer is worth to your business over their entire journey — whether that's a few months or a few years.
- CAC (Customer Acquisition Cost): What it costs to win that customer — ad spend, cold emails, demos, sales calls… it all adds up.
- LTV:CAC Ratio: Simply put, how much you earn vs. how much you spend to earn it.
If you’re spending more to get a customer than you make from them, red flag.
If you’re making way more than you spend? Great — but maybe you’re not investing enough in growth.
You want to be in the sweet spot — balancing smart growth with strong returns.
The Magic Numbers
Below 1:1 — Losing money. Yikes.
2:1 — Some profit, but room to improve.
3:1 to 4:1 — Ideal zone for most SaaS companies.
6:1 or more — Very profitable, but possibly too conservative.
What About Different Channels?
Some acquisition strategies cost more than others:
- Email Marketing: Super cheap — but only if you’ve got a solid list.
- Webinars: High effort, great engagement.
- LinkedIn Ads: B2B-friendly, but content quality is key.
- SEO (Thought Leadership): Long-term ROI, but slow to start.
