LTV & CAC Optimisation Tips
01
Reduce Churn First
A 5% reduction in monthly churn can increase LTV by 25–95%. Fix retention before scaling acquisition spend.
02
Target 3x LTV:CAC
Industry consensus is 3:1 minimum for sustainable growth. Below 3x means your acquisition is eating into profitability.
03
Shorten Payback Period
Aim for under 12 months payback. Faster payback means more cash to reinvest in growth and lower business risk.
