Authority
This definition follows Non-GAAP financial measure — SEC Regulation G — it is not a GAAP measure, so a registrant publishing it has to reconcile it to the nearest GAAP figure.
Every citation in this system, with the text we read and the date we checked it, is in US GAAP and where these rules come from.
Formula
Net new ARR in the quarter ÷ prior-quarter S&M (equivalently (Δ quarterly revenue × 4) ÷ prior-quarter S&M)
A metric without its definition is a number people argue about in meetings. Every metric component in this system requires one — see the rules.
Magic number, in use
Quoted from the 2 documents that use the word — what it does to an interface, in the spec's own sentence.
Everything in Metric definitions — ARR, EBITDA, net burn, runway, magic number — is a non-GAAP financial measure.
US GAAP, and where these rules come from — Metrics are not GAAP
That's how sheets hide off-screen and how toasts enter — it adapts to content and never needs a magic number.

No component names this concept outright. These are the ones in its part of the system, which is a weaker claim — but a component nothing links to is a component nobody finds.
