SaaS Magic Number

A sales-efficiency ratio measuring how much annualised new recurring revenue each euro of sales and marketing spend produced.

[01]What It Means

Net new ARR for the quarter is annualised by multiplying by four, then divided by the previous quarter’s sales and marketing expense. The lag is deliberate: spend takes a quarter to convert. Below 0.5 the engine leaks and more budget compounds the loss; 0.5 to 0.75 means refine before scaling; 0.75 to 1.0 is a repeatable motion that can absorb investment; above 1.0 argues for acceleration.

[02]Why It Matters

It is the number boards use to decide whether a go-to-market engine has earned more capital. In a market entry it also exposes the honest cost of the first year, when spend runs ahead of revenue by definition.

[03]Where It Goes Wrong

Reading it in the same quarter as the spend, which flatters a growing team and punishes a hiring one.Treating all revenue as equal: on service-heavy products the gross-margin-adjusted version tells a different story.Using it to justify cuts in a market that has not completed a single sales cycle yet.
