What is a good LTV:CAC ratio?
Your LTV:CAC ratio compares how much a customer is worth over their lifetime (LTV) to how much it costs to acquire them (CAC). It is the single clearest read on whether your growth is profitable: a ratio of 3:1 means each customer returns three times what you paid to win them. This calculator divides LTV by CAC to give you that ratio, plus the net value each customer leaves after acquisition, so you can see the health of your unit economics at a glance.
The widely-cited SaaS benchmark is 3:1 β high enough to be profitable, low enough that you are not underinvesting in growth. Below 1:1 you lose money on every customer; above 5:1 you may be leaving growth on the table by spending too little. Payback period matters too: even a strong ratio hurts cash flow if CAC takes many months to recover. One of the fastest ways to shift the ratio is to lower CAC β and higher-converting App Store screenshots turn the same ad spend into more installs, which is exactly what Reverze rebuilds.
