Frequently Asked Questions

What is burn rate and how is it calculated?

Gross burn = total monthly cash spent. Net burn = gross burn minus monthly revenue. Runway = current cash ÷ net burn rate. Your zero-cash date is today's date plus runway months.

What is a good burn multiple?

Burn multiple = net burn ÷ net new ARR. Below 1x is excellent. 1–1.5x is good. Above 2x concerns investors. Above 3x raises serious fundraising red flags. Benchmark varies by stage — Series B investors expect sub-1x efficiency.

How much runway before raising?

Start your fundraise with 12–18 months remaining; plan to close with 8–12 months left. Raising with under 6 months of runway puts you in a distressed position that weakens valuation and terms significantly.
