FAQ
What LTV:CAC ratio is usually healthy?
Many ecommerce teams target around 3.0x as a baseline, but acceptable ranges depend on margin and cash flow constraints.
Can a high ratio still be risky?
Yes. If payback is slow, growth can still create cash pressure even with a strong lifetime ratio.
Should ratio targets vary by channel?
Yes. Branded search often supports stronger ratios than colder social traffic, so channel-specific targets are useful.
