📖 Overview
This calculator converts stress planning into a clear runway timeline.
It models cash burn support income and realistic cuts together so you can see if your current plan gives enough time to recover.
🧪 Example Scenarios
Use these default and higher-pressure example inputs to explore how sensitive this calculator is before using your real numbers.
| Input | Base Case | Higher Pressure Case |
|---|---|---|
| Current Cash Reserve ($) | 42,000 | 37,800 |
| Current Monthly Burn ($) | 5,200 | 6,240 |
| Monthly Expense Cuts You Can Sustain ($) | 1,400 | 1,610 |
| Monthly Support Income ($) | 900 | 810 |
| One Time Emergency Costs ($) | 3,500 | 4,200 |
⚙️ How It Works
Estimates survival runway under job-loss conditions by combining available cash, one-time shocks, monthly support, and a practical cost-cut plan.
The Formula
| Cash | Liquid funds available for immediate survival use |
| Burn | Current monthly outflow including essential obligations |
| Cuts | Monthly reductions you can sustain without breaking essentials |
| Support | Monthly severance/unemployment/guaranteed inflow |
| One-time Costs | Immediate obligations that reduce usable runway cash |
Quick Reference
| Usable Cash | Net Burn | Runway |
|---|---|---|
| $30,000 | $3,000/mo | 10 months |
| $30,000 | $2,200/mo | 13.6 months |
| $45,000 | $2,500/mo | 18 months |
| $45,000 | $1,500/mo | 30 months |
When To Use This
- Use this tool when you need a fast decision during active planning or execution.
- Use this before committing money, time, or tradeoffs that are hard to reverse.
- Use this to compare options using the same assumptions across scenarios.
Edge Cases To Watch
- Results can be misleading if key inputs are missing, stale, or unrealistic.
- Very small or very large values may amplify rounding effects and interpretation risk.
- If assumptions change mid-decision, recalculate before acting.
Practical Tips
Frequently Asked Questions
❓ What if net burn becomes zero or negative?
That means cash-flow is neutral/positive and runway is no longer cash-limited under current assumptions.
❓ Should retirement savings be counted as runway cash?
Only if truly accessible and acceptable to use under your contingency plan.
