Emergency Fund Calculator
Determine how much money you should set aside in your emergency fund to cover unexpected expenses or loss of income.
Recommended: 3–6 months (up to 12 for variable income)
Formula
Emergency Fund Target = Total Monthly Essential Expenses × Coverage Period (months)
Where:
- Total Monthly Essential Expenses = Housing + Food + Transportation + Insurance + Minimum Debt Payments + Other Essentials
- Coverage Period = Number of months you want to be able to cover without income (typically 3–6)
- Remaining Gap = max(0, Target − Current Balance)
- Months to Goal = ⌈Gap ÷ Monthly Savings⌉
- Percent Funded = min(100%, Current Balance ÷ Target × 100)
Assumptions & References
- Only essential expenses are included — discretionary spending (dining out, subscriptions, entertainment) is excluded, as these can be cut during an emergency.
- The standard recommendation is 3–6 months of expenses (Consumer Financial Protection Bureau, CFPB). Freelancers, self-employed individuals, or single-income households should target 6–12 months.
- Emergency funds should be kept in a liquid, low-risk account such as a high-yield savings account (HYSA) or money market account — not invested in stocks.
- This calculator does not account for interest earned on savings. For a HYSA earning ~4–5% APY, your fund may grow slightly faster than projected.
- Minimum debt payments are included because missing them during an emergency has serious credit and legal consequences.
