Formula used
- Essential monthly total = sum of required monthly costs (housing, utilities, food, transport, minimum debts, insurance, other essentials).
- Risk points add months based on stability, variability, health uncertainty, coverage, and dependents (capped).
- Adjusted target months = base months + risk points (bounded between 3 and 18).
- Recommended emergency fund = essential monthly total × adjusted target months.
- Readiness (cash only) = (available cash buffer ÷ recommended fund) × 100.
- Months covered = available cash buffer ÷ essential monthly total.
- Months to goal = funding gap ÷ monthly contribution (if provided).
