Cash Runway Calculator

This Cash Runway Calculator answers the first number a board and a lender ask about: how long does the cash last? Enter your cash on hand, expected monthly collections, and operating spend, and it returns your net monthly burn, the number of months of runway you have left, and a projected zero-cash date. Treat the result as a planning baseline, not a promise — it is the same starting math we run before building a full 13-week forecast on a client's live numbers.

For how that model is built and why lenders rely on it, read the 13-week cash flow forecast field guide. Book a working session to have it built on yours.
