About Toolwoven Cash Runway Planner
A month-by-month cash runway calculator for small businesses and early-stage teams.
How it works
Enter cash, monthly revenue and expenses with optional growth, then add planned changes on the months they happen: a hire, a funding round, a one-off cost. The planner shows runway, the month cash runs out, net and gross burn, the lowest balance and when a minimum buffer is breached, and compares the base case with lower revenue and higher costs. Print the forecast, export the monthly table as CSV or copy a summary.
Everything runs in your web browser. The plan is kept in this browser's local storage so it is there when you come back; Clear saved plan or clearing this site's browser data removes it. It is a planning model, not financial advice.
