What is a good LTV:CAC ratio for e-commerce?
A healthy LTV:CAC ratio is 3:1 or higher. If your LTV is $90 and CAC is $30, you're sustainable. Below 1:1 means you're losing money on every customer acquired.
How to calculate Customer Lifetime Value (LTV)?
LTV = Average Order Value x Purchase Frequency per Year x Average Customer Lifespan in Years. Improving repeat purchase rate dramatically increases LTV without ad spend.
How to reduce CAC in e-commerce?
Focus on organic SEO content marketing, referral programs (each customer brings another), email list retargeting (much lower CPM), and improving landing page conversion rates.
