Cash Runway Calculator

Enter figures from a company’s latest balance sheet and cash flow statement. The calculator converts year-to-date cash burn to a monthly rate and shows runway from the balance sheet date and after the time that has already passed.

Debt repayments due

Runway estimate

Liquid cash

$15,000,000

Monthly burn

Hypothetical illustration of how the contract arithmetic works. It is not a forecast of any company’s share count or price, and it is not investment advice.

How the numbers are calculated

Liquid cash = cash and equivalents + short-term investments + cash raised since the balance sheet date − known debt repayments. Restricted cash is excluded.
Monthly burn = (net cash used in operating activities + capital expenditures) ÷ months the statement covers.
Runway = liquid cash ÷ monthly burn, measured from the balance sheet date.
Runway now = runway − months elapsed since the balance sheet date.

Notes and limits

A 10-Q cash flow statement is year to date: a third-quarter 10-Q covers nine months. Enter the months it covers, or use a single quarter’s figures with 3 months to see the latest rate.
If operating cash flow is positive, runway is not a meaningful measure and none is shown.
Runway assumes spending continues at a measured past rate and no new money arrives. It describes a funding need, not when or how it will be met.
