Startup Runway Calculator
Enter your cash on hand and monthly burn rate to see how many months of runway you have and the projected date you'd run out of cash.
Startup Runway Calculator
Calculates how many months of cash runway a startup has left and projects the date it runs out at the current burn rate.
This calculator divides your current cash balance by your monthly burn rate to find how many months of runway remain, then projects an approximate calendar date when cash would run out at the current pace. It's a standard, widely used startup finance metric for gauging urgency around fundraising or cost-cutting — since it assumes a constant burn rate, it's best used as a snapshot that you recalculate regularly as your spending and revenue change.
Example
- With the default values shown above, this calculator returns: Months of Runway ≈ 7.1 months; Projected Runway End Date = 2027-04-13.
Frequently Asked Questions
What is 'burn rate'?
Burn rate is the net amount of cash a company spends per month after accounting for any revenue coming in — it's the pace at which your cash balance is shrinking.
Does this account for changing burn rate over time?
No — it assumes a constant monthly burn rate, which is a simplification; if your spending or revenue is expected to change significantly, recalculate with an updated burn rate as your situation evolves.
