How big should your emergency fund be?

Job loss. A hospital bill. Your laptop dies the week before a deadline. Life doesn't send a calendar invite before it gets expensive. An emergency fund is the money that makes sure a bad week doesn't become a bad year.

How much do you need?

The common rule is 3 to 6 months of your expenses. Not your salary, your expenses.

Here's how to find your number:

1. Add up what you spend in a normal month on needs: rent, food, bills, EMIs, insurance, travel.
2. Multiply by 6.

If your monthly expenses are ₹25,000, your emergency fund target is ₹1.5 lakh.

Go closer to 6 months (or more) if you're the only earner at home, you freelance or have irregular income, or your job feels shaky.

3 months can be enough if you have a stable job, a second earner in the family, and good health insurance.

Where to keep it

An emergency fund has one job: be there, in full, the day you need it. So it needs to be safe and quick to withdraw. Returns come last.

Good places:

• A separate savings account, not the one you spend from. Out of sight, out of mind.
• A sweep-in fixed deposit, which earns a bit more but can still be broken quickly.
• A liquid mutual fund, for the part you're unlikely to need on day one.

Avoid putting it in stocks or equity funds. Emergencies love to show up exactly when markets are down.

How to build it without feeling it

₹1.5 lakh can feel huge. Don't try to build it in one go.

• Start with a mini target of one month's expenses. Hitting that first goal feels great and builds the habit.
• Set up an automatic transfer on salary day, even ₹3,000 or ₹5,000.
• Put bonuses, refunds and gifts straight into it until you hit the target.

Once it's full, stop adding and send that money to your SIP instead.

What counts as an emergency

Medical bills, job loss, urgent home or vehicle repairs, a family crisis. A new phone launch is not an emergency. Neither is a sale. If you use the fund, refill it before anything else.

Do this before you invest

It sounds boring, but an emergency fund is what lets you invest with confidence. Without one, the first surprise bill forces you to sell your investments, often at a loss. With one, your SIP keeps running no matter what.

Once your fund is ready, see what your monthly savings can grow into with the SIP calculator. And if you're new to budgeting, start with the 50/30/20 rule.

Peace of mind is the best return this money will ever give you.
