Cash
Investors do this arithmetic before the call. It is better if you have done it first.
Burn rate tells you how fast money leaves. It says nothing about whether the spending is working. The burn multiple, net burn divided by net new annual recurring revenue over the same period, tells you how many dollars you consume to add a dollar of recurring revenue.
Lower is better. A multiple under one is exceptional and rare. Between one and two is strong. Two to three is workable at an early stage and expected to improve. Above three, the honest reading is that growth is being purchased rather than earned, and the number needs a story attached: a deliberate land-grab, a long enterprise sales cycle just now converting, a one-time infrastructure build.
Compute it the same way every quarter
Net burn is cash out minus cash in, not the loss on your income statement. Net new ARR is new plus expansion minus churn and contraction. Pick the definitions, write them down, and do not quietly change them in a bad quarter.
Read it alongside months of runway, net revenue retention, and CAC payback period. Burn multiple tells you the efficiency of growth, runway tells you how long you have to improve it, retention tells you whether the revenue you bought stays.

A short call is usually enough to tell you whether there is anything here worth acting on.
