About Cash Runway Calculator
Cash Runway Calculator estimates how long a business's current cash could last from monthly expenses and expected monthly inflow.
Runway is calculated from current cash divided by net monthly burn when expenses exceed inflow. It is a simple planning scenario, not a financial forecast or guarantee. Runway = cash in bank ÷ monthly net burn. It is the startup metric that matters most, because companies die when cash hits zero, not when they become unprofitable on paper. The calculator makes the countdown explicit. Business documents and calculations depend on accurate fields, totals, dates, tax assumptions and the final document format. Review names, amounts, dates, totals, currency, tax and the exported document before sending it.
Primary objective: Estimates modeled cash runway from current cash, monthly expenses and monthly inflow.
Privacy assurance: The document is prepared in the browser from the information you enter.

Frequently Asked Questions
What is cash runway?
It is an estimate of how long available cash can support a modeled net burn rate.
What if inflow is higher than expenses?
The simplified model reports no positive monthly burn and therefore does not give a finite depletion period.
Is runway a prediction?
No. Actual cash movements can differ substantially from the assumptions.
What counts as "cash in bank"?
Liquid, accessible funds — not credit lines, not "expected" revenue. Runway math must be conservative to be useful.
How do I extend runway?
Cut burn (the fast lever), raise revenue, or raise funding. Cutting burn 20% extends runway 25% — the math rewards frugality non-linearly.
What is a safe runway?
12–18 months is the conventional comfort zone for startups; under 6 months is emergency territory requiring immediate action.
