Frequently Asked Questions
What is startup runway?
Startup runway is the number of months a company can operate before running out of cash, based on its current cash balance and net monthly burn rate. Net burn = monthly expenses minus monthly revenue. A runway of 18-24 months is considered healthy for a startup raising its next round.
How do I calculate my burn rate?
Burn rate is your total monthly cash outflow - including salaries, rent, software, marketing, and all other costs. Gross burn is total spending. Net burn is gross burn minus monthly revenue. To calculate runway: divide your current cash balance by your net monthly burn rate.
What is a good runway for a startup?
Most investors recommend maintaining at least 18-24 months of runway at all times. If you are planning to raise a funding round, start the process with 12+ months of runway remaining - fundraising typically takes 3-6 months and you need buffer for negotiation and unexpected delays.
