Stress-test result
Need month-specific assumptions?
The paid planning pack accepts 3–36 distinct months, financing inflows and outflows, explicit one-time adjustments, a minimum operating buffer, and as many as 12 named scenarios. It returns the full month-by-month path, break-even timing, required opening cash, scenario rank, commitments, and a reproducible plan hash.

How to read the result
- Below buffer means the modeled closing cash crossed the minimum you entered.
- Below zero means the supplied constant inflow/outflow assumptions exhausted opening cash.
- Additional opening cash is the amount needed to keep the modeled closing balance nonnegative through the selected horizon.
