Runway and burn rate questions
What is cash runway?
Runway is how many months you can keep operating before cash runs out, found by dividing the cash you have by your net monthly burn.
What is burn rate?
Burn rate is the cash you lose each month. Net burn is your monthly expenses minus the cash you receive.
How many months of runway should a startup have?
Many founders aim to keep well over 12 months and start raising or cutting costs when it falls below about 6 to 9 months, because fundraising takes time. Your own situation may differ.
How can I extend my runway?
Reduce expenses, collect receivables faster, raise prices, or raise money. Accurate monthly books show where the cash is going.
