Mastering Your Cash Runway
Understanding your burn rate is a matter of business survival. It tells you exactly how fast you are spending your capital reserves. The PennyWiseUSA Burn Rate Calculator is an essential tool designed to demystify cash flow projections and determine exactly when you will run out of money if conditions don't change.
The Formulas We Use:
- Gross Burn Rate = Total Monthly Outflows (Expenses)
- Net Burn Rate = Total Monthly Outflows - Total Monthly Inflows
- Cash Runway (Months) = Current Cash Balance ÷ Net Burn Rate
By consistently calculating your burn rate, founders can accurately time their next fundraising round, decide whether to expand the team, or identify when aggressive cost-cutting measures are required to keep the lights on.
