📖 Overview
Use this calculator to measure resilience if income is interrupted.
🧪 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 |
|---|---|---|
| Savings Balance ($) | 18,000 | 16,200 |
| Monthly Expenses ($) | 3,000 | 3,450 |
⚙️ How It Works
This measures how long current savings can cover expenses by dividing savings balance by monthly spend.
The Formula
Coverage (months) = Savings Balance ÷ Monthly Expenses
| Coverage | Number of months expenses can be covered without income |
| Savings | Current liquid savings balance |
| Expenses | Total essential monthly expenses |
💡Most financial planners recommend 3–6 months of essential expenses. If your income is variable or you are self-employed, target 6–12 months.
Quick Reference
| Coverage | Situation | Recommendation |
|---|---|---|
| < 1 month | Vulnerable | Prioritise building savings immediately |
| 1–3 months | Minimal | Adequate for dual-income households |
| 3–6 months | Standard | Recommended for most individuals |
| 6+ months | Strong | Recommended for self-employed or variable income |
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
💡 Recalculate after major expense changes.
💡 Track essential expenses separately from discretionary spend.
💡 Aim for a buffer that matches your income stability.
