Why does Burn Multiple matter?
A growth rate on its own says nothing about what the growth cost, and two companies growing identically can be entirely different investments. The burn multiple is the shortest answer to whether more capital buys more growth or merely buys more time, which is the question every investor is actually asking. It changes internal decisions too: a multiple that rises through a growth push means the growth is being bought rather than earned, and that is worth knowing before the next round rather than during it.
What does Burn Multiple look like in practice?
Suppose a company burns $500k net in a quarter and adds $250k of net new ARR. The multiple is 2, two dollars out for each dollar of new recurring revenue. A second company burns $1.5M and adds $1M, a multiple of 1.5, and is the more efficient business despite spending three times as much. The word net matters on both sides: churn subtracts from new ARR, so a company with strong gross additions and heavy churn posts a poor multiple while its sales team looks excellent, which is the exact pattern the metric is good at exposing.
What are the common mistakes with Burn Multiple?
- Using gross new ARR instead of net, which hides churn behind sales performance.
- Comparing across stages. A company finding its first customers has a naturally terrible multiple, and the figure only starts meaning something once growth is repeatable.
- Reading one quarter as a trend. A single large annual prepayment or a delayed hire moves it enough to tell either story.
- Optimizing the ratio itself. A company that stops spending posts an excellent multiple and no future, which is why it is read alongside the growth rate rather than instead of it.
