Emergency Fund
Also known as: rainy day fund, safety net, contingency fund
An emergency fund is a pool of easily accessible cash set aside to cover unexpected expenses without forcing you to break investments or take on debt.
An emergency fund is the foundation of personal finance. Without one, the first unexpected expense — a medical bill, a job loss, a major repair — forces you to either liquidate investments at the worst possible time or pile on high-interest debt.
The standard guideline is 3 to 6 months of essential monthly expenses. Lean towards 3 months if you have very stable salaried income, dual incomes in your household, and no dependents. Lean towards 6–12 months if you're self-employed, the sole earner, or in a volatile industry.
Calculate only essential expenses, not your full monthly spend. Include rent or EMI, utilities, groceries, insurance, dependent care, loan EMIs, and basic transport. Exclude discretionary spending — that's the first thing you'd cut in an emergency.
Park the fund where it's liquid and safe, not in equities. A combination of a high-interest savings account, a sweep-in fixed deposit, and a liquid mutual fund works well. The goal is same-day access without losing principal — earning a few percent interest is a bonus, not the point.
