SaaS Magic Number

What is it?

The Lifetime Value to Cost of Acquisition (LTV/CAC) Ratio tells you if the theoretical lifetime revenue you get from a customer is higher or lower than the sales and marketing costs needed to acquire that customer.

The SaaS Magic Number is a ratio showing yearly recurring revenue growth gained for every sales and marketing dollar spent. It indicates the level of operational efficiency of a company, as well as the sustainability of sales and marketing expenditure.

Formula

ƒ (Customer Lifetime Value) / (Customer Acquisition Cost)
ƒ ((ARPA x Gross Margin) / Churn Rate ) / Customer Acquisition Cost
ƒ ((current quarter’s recurring revenue – previous quarter’s recurring revenue) x 4) / (previous quarter’s sales and marketing spend)
