This is a planning estimate based on the values entered here. It is not RunwayCal's product-derived True Cash Position and is not a guarantee of what is safe to spend.
See how different assumptions change runway.
Try a hiring, revenue or cost change and compare the estimate before you commit.
Choose an assumption above to see how it changes the estimate.
A runway estimate is only as useful as the inputs behind it.
A calculator can test arithmetic. A business decision still needs reviewed inputs, obligation timing, and a clear boundary between actual financial reality and a hypothetical case.
Need the estimate connected to the rest of the business?
RunwayCal connects cash, commitments, revenue, team costs, planning and reporting so the estimate is not isolated from the numbers behind it.
