An emergency fund is the foundation of a healthy financial plan. It covers real shocks without forcing you to sell investments at a bad time or borrow at high interest.
The common guideline is three to six months of essential expenses. If your income is stable, three months may do; if you are self-employed or a sole earner, aim for six or more.
Keep it somewhere safe and reachable within a day or two — a separate savings account, a liquid fund, or a sweep-in fixed deposit. The goal is safety and access, not high returns. Read our full emergency fund guide to build one.
