What It Is
Cash runway is how long a company can continue operating at its current rate of cash consumption before running out of money. It is calculated by dividing the current cash balance by the quarterly or monthly cash burn rate. Expressed in months or quarters.
Why It Matters
For companies that are pre-revenue or early-stage, cash runway is the single most important operational number. It determines whether the company survives long enough to reach the next value-creating milestone. An eight-quarter runway is operational room. A four-quarter runway with no clear path to revenue or financing is existential pressure that changes how every other piece of information about the company should be interpreted.
Where to Find It
In the balance sheet (cash and cash equivalents) and the cash flow statement (operating cash outflow) of the most recent 10-Q. Cash divided by quarterly operating cash outflow equals quarters of runway. Watch for the trend is runway extending or shrinking quarter over quarter?
Real Example
Rigetti Computing, Q1 2026. The company ended Q1 with $569 million in cash. At recent burn rates, the runway extended well beyond the next technical milestone. That makes the $100 million government funding commitment meaningful but not urgent. For a quantum computing company where the commercial proof is still years away, having runway is necessary but not sufficient. The question is whether the milestones the runway is buying are actually achievable.
