How to read this
Runway = available cash ÷ (monthly spending − monthly receipts). This simple estimate excludes payment timing, seasonality, taxes, debt repayments and one-off transactions unless included in your inputs.
A monthly average can hide a shortfall within the month. Use a dated cash-flow forecast for decisions. This is a planning aid, not financial advice.
