Cash & Working Capital
Cash Runway Calculator
How many months until the cash runs out at your current burn — the single most important number for a business that isn’t yet profitable.
Inputs
- Cash in the bank — Money you can actually spend right now.
- Monthly expenses — Everything you pay out in a typical month.
- Monthly revenue — Cash actually coming in per month.
How to use this calculator
- Enter your cash on hand, monthly expenses, and monthly revenue.
- The tool nets expenses against revenue to find your burn, then your months of runway.
- Plan your next raise or profitability push with at least a six-month buffer, not at zero.
