Frequently asked questions

What is the difference between gross burn and net burn?
Gross burn is total cash going out each month. Net burn subtracts monthly revenue from that, so it is the true rate at which cash is disappearing from the bank.
What if we are cash-flow positive?
Then net burn is zero or negative and runway is effectively unlimited. The calculator flags this and shows the projected balance rising instead of falling.
Does runway include a future raise?
No — this is the cash-on-hand projection only. Model new funding separately once you know the raise you want to plan for.
