⏳ Cash Runway Calculator
Runway is the countdown clock every founder should know cold: cash on hand divided by what you lose each month. It decides how bold you can be and when you need revenue or funding to arrive.
Months of runway
6 months
Net burn per month
$2,500
You burn $2,500 a month, so your cash lasts about 6.0 months. The two ways to extend it: cut the burn, or grow revenue; even $1,250 more monthly revenue doubles your runway.
Estimates for planning, not financial advice. Your real numbers will vary; that is exactly why you track them.
Good questions about this math
How much runway is safe?
Six months is the common comfort line for a small business; under three months means act now (cut costs, chase receivables, push sales) rather than hope. More than a year of runway with no growth usually means you are being too cautious.
Does runway include my own pay?
It should. Put the amount you must draw to live inside monthly expenses; a runway that only works because you starve is not a real runway.
