An emergency fund is money you can reach within a day or two, kept only for things you did not plan: a job loss, a hospital bill, an urgent family trip, a car repair. Its job is not to grow. Its job is to stop a bad month from turning into a credit-card balance or a broken investment plan.
How much is enough?
A common target is six months of essential outgoings — rent or EMIs, groceries, utilities, school fees, insurance premiums and transport. Use your real spending, not your income. If you have a single income in the household, variable pay, or dependent parents, aim for nine to twelve months. If two people earn and both jobs are stable, three to six months can be enough.
Count EMIs as part of the target. Banks expect the instalment whether or not you are paid, so a fund that ignores them runs out faster than you expect.
Where to keep it
The rule is simple: safe first, available second, return last.
- Savings account: keep roughly one month here for instant access.
- Sweep-in or short fixed deposits: a ladder of FDs with staggered maturities earns more than a savings account and most can be broken early with a small penalty.
- Liquid or overnight funds: redemptions usually reach your bank on the next working day. Returns are not guaranteed, but the risk is low.
Avoid equity funds, PPF and locked-in products for this money. They are good investments, but not available on the day you need them.
A simple plan to build it
- Find your number. Add up three months of essential spending and EMIs, take the monthly average, and multiply by your target months.
- Start with one month. Move the first month's worth from any idle balance. This alone protects you from most small shocks.
- Automate the rest. Set up a transfer on pay day — even 10% of take-home pay closes a six-month gap in a few years. A recurring deposit works well because it is hard to skip.
- Send windfalls here first. Bonuses, tax refunds and gifts can fill the fund quickly.
- Refill after use. When you dip into the fund, pause other extra investing until it is back to target.
Should I invest or build the fund first?
Do both, in proportion. Keep any existing SIPs running — stopping them breaks a good habit — but direct new surplus to the emergency fund until you reach at least three months. Then split surplus between the fund and investments until the fund is complete.
Keep it honest
Review the target once a year, or whenever your rent, EMIs or family situation changes. An emergency fund sized for last year's expenses quietly shrinks as costs rise.
In FID, mark your savings account and FDs as "available in an emergency" on the Holdings page. Your financial health score then shows how many months you are covered, and updates as you add to it.
