An emergency fund is money set aside for unplanned expenses — job loss, medical bills, home repairs, family emergencies. The standard advice is "6 months of expenses" but that one-size-fits-all rule ignores your income type, dependents, and risk tolerance.
A smarter framework
Start with 3 months if you have a stable salaried job, no dependents, and low fixed costs. Go to 6 months if you have dependents or a mortgage. Push to 12 months if you're self-employed, in a cyclical industry, or the sole earner in your household. The idea is that your fund should cover you through a realistic worst-case scenario for your specific situation.
Where to park it
Emergency funds need to be safe and liquid, not high-return. The best options are a savings account (earning 3–4%), a liquid fund (earning 6–7% with T+1 redemption), or a sweep-in FD that auto-liquidates when you need cash. Avoid equity, gold, and anything with exit loads.
Build it before anything else
Before you SIP into equity funds, before you buy stocks, before you max out your ELSS — build the emergency fund first. The mathematical return on an emergency fund is low, but the psychological return during a real crisis is enormous. It's the foundation that lets you invest the rest without panic.
Replenish after use
If you dip into your emergency fund, rebuilding it becomes priority #1. Pause equity SIPs temporarily if needed. A depleted emergency fund is a loaded gun pointed at your long-term plan.
