What runway means
Runway is the time until your cash runs out at the current rate of spending. It is cash on hand divided by monthly burn.
It assumes costs stay flat and no new money comes in. Real runway changes when you hire, cut costs, or earn revenue, so recalculate whenever those change.
Plan fundraising or cost changes well before the end of the runway, because both take time.
The formula
Runway (months) = cash on hand ÷ monthly burn, where monthly burn = the total of your monthly costs.
Common questions
How do I calculate startup runway?
Divide your cash on hand by your monthly burn. If you have ₹25,00,000 and spend ₹2,75,000 a month, runway is about 9.1 months.
What is burn rate?
The amount of cash you spend each month. Net burn subtracts monthly revenue, gross burn does not. This calculator uses the total costs you enter.
How much runway should a startup have?
There is no single number. Many founders aim to keep enough runway to raise money or reach profit without being forced to decide in a hurry.
Does this include revenue?
No. Enter your net monthly costs if you want to include revenue (costs minus revenue).
