What it means
Payback period is the time taken for the cash returns from an investment to equal its cost.
Why it matters
For a cash-constrained business it is often more relevant than ROI: a 40% return over seven years is no use if you run out of money in year two.
What it looks like in practice
For customer acquisition, CAC payback is the months of gross margin needed to recover the acquisition cost. Under twelve months is comfortable for most businesses.
What to watch out for
Payback ignores everything after the payback point, so it undervalues long-lived investments. Use it alongside ROI, not instead.
Where to get proper advice
Your accountant, who can produce most of these from data they already hold.
