Frequently Asked Questions
Monthly Burn = (Starting Cash minus Ending Cash) divided by Number of Months. It's an average burn rate over the period you specify, not a month-by-month breakdown.
It's net burn - the actual change in your cash balance over the period, which already nets out any revenue collected against expenses paid.
Yes - once you have your monthly burn rate here, enter it along with your current cash balance into the Startup Runway Calculator to see how many months of runway you have left.
