It is July in Guwahati and it has rained for three days. On the fourth, something breaks: the scooter, a tooth, the roof over the kitchen, or a job that was supposed to be safe. The bill arrives before the salary does.
What happens next depends almost entirely on a decision made months earlier: whether there was money set aside that could be reached within a day or two, close to its full value. That money is an emergency fund, and the best thing it can be is boring.

Its only job
Most money has a goal: a house, a child's education, retirement. An emergency fund has a job instead. It has to be there, quickly, when something goes wrong: a job loss, a hospital bill, an urgent repair, a family emergency far from home.
That job sets two conditions. You must be able to reach the money within a day or two, and it must be worth close to what you put in when you do. Growth is welcome, but it is not the job. A fund that grows well but is sharply down in the month you need it has failed at the only thing it was for.

How big should it be?
A common starting point is three to six months of essential expenses. Essential means what you would still have to pay if income stopped: rent or EMI, groceries, electricity and phone, school fees, insurance premiums, the money you send home.
Lean towards the upper end, or beyond it, if your household depends on one income, if your income is irregular (a business, freelance work, commission), or if you support your parents. A household with two stable incomes and few dependants can often start lower.

Where it can sit
- A savings account, for the first few weeks of expenses. It is available at once, and that is all it needs to be.
- Liquid or overnight fund categories, for the rest. These invest in very short-term debt instruments. Their risk is low, not zero, and redemption money typically reaches your bank account by the next business day.
Where it should not sit
- Equity funds. Their value can be down exactly when you need the money.
- Anything with a lock-in, such as ELSS, where each investment is locked for three years.
- Property, gold jewellery, or money lent to family. All are slow or awkward to turn back into cash at full value.
- A credit card limit. That is a loan, not a fund, and it charges interest from the day you use it for an emergency.
Building one on a first salary
If this is your first job, an emergency fund is a sensible first project, before most other investing. It does not need to be built in one go.
- Work out one month of essential expenses. That is your first target.
- Keep it in a separate account or scheme, so it does not quietly pay for a weekend.
- Set up a fixed monthly transfer on salary day, the same way a SIP works.
- Once one month is covered, aim for three, then six.
- When you use it, refill it before starting anything new.
Then leave it alone. It will not be the most interesting money you own. That is the point. If you would like help working out the right size for your household, and where it should sit, talk to us.
Growth is for your other money. This money only has to be there.
