Educational explainer: Startup runway: calculate months of cash at the current net burn

Cash runway estimates how long a business can continue funding operations from cash available, given its current net cash burn. A simple first pass is usable cash ÷ monthly net burn. Net burn is cash paid out minus cash received over the period; it is not automatically the same as an accounting loss. Timing of collections, tax payments, debt repayments and one-off purchases can materially change the monthly cash picture.

Worked example. A small firm has ₹18 lakh of unrestricted operating cash and spends ₹8 lakh a month while collecting ₹5 lakh. Its current net burn is ₹3 lakh per month, giving a simple estimate of six months (₹18 lakh ÷ ₹3 lakh). If ₹3 lakh of that balance is reserved for taxes or committed supplier payments, usable cash is ₹15 lakh and the estimate falls to five months. If a large customer pays late, the calendar runway can shorten even when the monthly average looks unchanged.

Use a rolling cash forecast, not one static division. List expected receipts and committed payments by week or month; separate restricted or earmarked cash; model a slower-collections case; and identify which costs can actually be changed without harming delivery. Update the calculation when hiring, financing, inventory or customer terms change. A runway figure is a planning signal, not proof that a lender will finance the company or that a business is viable.
