How big your emergency fund should be

The standard advice is six months of expenses. It's a reasonable place to start, and that's all it is. A single-income family with a home loan and two school-going children needs a very different cushion from a couple with two steady salaries and no EMIs. Here's how I'd build the number from your actual situation instead of borrowing someone else's.

What the fund is for, and what it isn't

An emergency fund covers two kinds of trouble. The first is income stopping: a layoff, a business slowdown, an illness that keeps you away from work. The second is a large expense that can't wait: a hospital deposit before the insurer settles, a leaking roof in the middle of the monsoon, a flight home because a parent is unwell. It isn't for a planned holiday, a Diwali purchase or a phone upgrade. Those are goals with dates, and they deserve their own savings.

It also isn't insurance. If the earning member dies, an emergency fund buys a few months; term insurance is what replaces years of income. Health insurance pays for hospitalisation; the fund covers the gaps, such as co-payments, items the policy excludes, and the days spent waiting for a cashless approval that doesn't come. The sizing below assumes those covers are in place. If they aren't, fix that first, because no realistic pile of cash can stand in for them.

Start with the monthly number

Use essential monthly outflow, not total spending. Include rent, groceries, electricity and other utilities, school fees (averaged per month), insurance premiums, transport to work, regular medicines, and money you send to parents. Leave out eating out, subscriptions you'd cancel within a week, and SIPs you'd pause if income stopped. The easiest way to get an honest figure is to go through the last three months of bank and card statements rather than guessing.

Then add every EMI. This is the part people leave out. A home loan EMI doesn't pause because you've lost your job, and missing it hurts your credit score at exactly the moment you might need to borrow. Car loans, personal loans, the no-cost EMI on a phone or a fridge: they all go in.

Choose the number of months

The months multiplier is where your situation really shows up. Think about how long it would realistically take to replace the income, not how long you hope it would take. Here's how I'd set it:

• Two incomes, both stable, no dependents: 3 to 4 months. If one job goes, the other salary covers much of the essentials.
• Two incomes, with children or parents depending on you: about 6 months.
• One salaried income: 6 to 9 months, towards the upper end if you work in a field that hires slowly or hold a senior role, which tends to take longer to replace.
• Freelancers, commission earners and business owners: 9 to 12 months, because income can shrink gradually without a clear moment when it stops.
• A known health condition in the family, or retirement within a few years: move to the top of whatever range applies.

I'd be careful about rating your own job as safe. A government post with a pension is genuinely different. A private-sector job at a company that's doing well is less so, because restructuring decisions are usually made well above the level of individual performance.

A worked example

Take a household with ₹45,000 of essential monthly spending and an ₹18,000 home loan EMI. One parent earns; there's one child. The monthly need is ₹45,000 + ₹18,000 = ₹63,000.

At six months, that's ₹63,000 × 6 = ₹3,78,000. The emergency fund calculator adds a simple planning buffer of ₹50,000 per dependent (counting the child, that's ₹50,000 here) plus a medical buffer you choose. Say ₹1,00,000 to cover a hospital deposit and the items a health policy won't pay for. The target becomes ₹3,78,000 + ₹50,000 + ₹1,00,000 = ₹5,28,000.

Because this is a single-income household, nine months is easier to defend. ₹63,000 × 9 = ₹5,67,000, and adding the same ₹1,50,000 of buffers gives ₹7,17,000. If the family has ₹2,00,000 in savings today, that covers ₹2,00,000 ÷ ₹63,000, or about 3.2 months, and the gap to the nine-month target is ₹5,17,000.

A gap that size can feel discouraging, so don't let it stall everything. At ₹25,000 a month, ₹5,17,000 takes 21 months: twenty months gets you to ₹5,00,000 and the twenty-first finishes it. I'd keep a smaller SIP running alongside rather than stopping all investing, but the fund gets first claim on any bonus until it's full.

Where to keep it

Emergency money has one job: be there, at full value, quickly. Return comes last. I think of it in three layers, sorted by how fast you can get to the money.

Same day. Keep about one month's need in your savings account. UPI and net banking move it in minutes at any hour, and this is what pays for a late-night hospital admission or an emergency train ticket.

Within a day. Use a sweep-in facility or a set of small FDs at the same bank. With auto-sweep, balance above a threshold in your savings account moves into FDs and is broken automatically when the account runs short, so it earns FD-type interest without any action from you. Ordinary FDs can usually be broken online, typically with a penalty of 0.5 to 1 percentage point off the rate. Splitting the amount into several smaller FDs means you only break what you need. The FD calculator shows what each piece will earn.

One or two working days. A liquid mutual fund. Redemptions are normally credited on the next business day, and many liquid funds also offer instant redemption up to a limit. Check your fund's limit before you rely on it. Liquid fund units bought on or after 1 April 2023 are taxed at your slab rate on redemption, the same rate as FD interest, so the advantage is mostly that tax comes later.

Two cautions. Bank deposits are insured by DICGC up to ₹5 lakh per depositor per bank, so if your fund is bigger than that, split it across two banks. And don't count a credit card limit, a pre-approved personal loan or your equity funds as emergency money. Credit is expensive debt you'd be taking on at the worst time. Equity can be down sharply in exactly the kind of downturn when job losses also pick up, which is the worst moment to be forced to sell.

Using it, then rebuilding it

The fund only works if you actually use it. Putting a hospital bill on a credit card to protect the fund, then paying card interest, defeats the purpose. Spend it when the emergency is real, and don't feel guilty about it.

After a withdrawal, refilling it becomes the first call on your savings until it's back at target. Write down the amount you took and set a fixed monthly refill, as if it were an EMI you owe yourself. If you used ₹1,50,000 for a family member's hospital stay, a refill of ₹15,000 a month restores it in ten months. Any insurance reimbursement that arrives later goes straight back into the fund, not into spending.

Revisit the target whenever something fixed changes: a new EMI, a child starting school, a parent moving in, a switch from salary to consulting. A target you set before taking a home loan is almost certainly too small now. And if you're tempted to put spare cash into your home loan before this fund is complete, read prepaying a home loan first. Money paid into a loan doesn't come back out easily.

Here's where I'd start this week. Pull the last three months of statements, add up the essential spending and EMI debits, divide by three, and enter that monthly figure in the emergency fund calculator with the months that match your household from the list above. The gap it shows is your first savings target, before anything else.
