ROAS, CAC, and the number most people skip
Return on ad spend tells you what a campaign returned this month. It does not tell you whether the campaign was a good idea. That answer lives in cost to acquire a customer measured against lifetime value, which is why this calculator returns both a first-month ROAS and an LTV-adjusted ROAS.
Break-even cost per lead is the figure to write on a sticky note. It is the most you can pay for a lead before the first sale loses money, and it turns every media-buying decision into a yes or no instead of a debate.
Use it before you pitch a retainer. If a client's numbers cannot support a profitable cost per lead, no amount of creative testing will rescue the account, and knowing that early is worth more than the retainer.
