FAQ
Frequently asked questions
What should be included in 'total spend'?
All marketing and sales costs directly tied to acquiring those customers, such as ad spend, sales salaries, and tools.
How is CAC used with LTV?
Comparing CAC to Customer Lifetime Value (LTV) shows whether acquisition spend is sustainable — LTV should meaningfully exceed CAC.
What's considered a healthy LTV:CAC ratio?
A common benchmark is at least 3:1 (LTV three times CAC or more).
Does a lower CAC always mean a better strategy?
Not always — a slightly higher CAC can be worthwhile if it brings higher-value, longer-retained customers.
