Runway calculator

Net burn = monthly cash outflow − monthly cash inflow. For a constant positive burn, runway = available cash ÷ monthly net burn. If burn is zero or negative, your cash is not depleting under these assumptions. This is a planning aid — not a promise of survival and not investment advice.

Available cash (AED)

Monthly operating costs (AED)

Monthly revenue (AED)

One-off change to cash (AED, optional)

Try the worked example: 120,000 cash · 20,000 costs · 0 revenue → 6 months.

Assumptions: costs, revenue and burn stay constant each month; the one-off change applies in month 1; taxes, timing of collections and future fundraising are not modelled. Change an input and recalculate to compare scenarios. More founder tools.
