"Keep six months of salary aside" is the line everyone repeats. It is a fair starting point, but it is often the wrong number. The right size depends on what you spend, who depends on you and how steady your income is.
What the fund is for
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 your policy does not fully cover, a parent who needs help, a car repair before a long drive. It is not the holiday fund and it is not the money for next year's school admission. Those are goals, and goals get their own plan.
Its real job is to stop you from doing something expensive in a bad week: breaking a long-term SIP when markets are down, borrowing on a credit card at high interest, or surrendering an insurance policy early.
Start with expenses, not salary
Multiplying your salary is the common mistake. If you take home ₹1,00,000 and spend ₹55,000, six months of salary is ₹6 lakh while six months of spending is ₹3.3 lakh. In a real emergency you cut the extras, so the fund only has to carry what you cannot stop paying.
List the monthly costs that would continue even if income stopped tomorrow:
- Rent or maintenance, electricity, gas, water, phone and internet
- Groceries, milk, household help and basic travel
- School fees, medicines and regular care for parents
- Insurance premiums (spread the yearly ones over 12 months)
- Any fixed monthly repayment you already carry
Leave out eating out, shopping, new SIPs and anything you could pause for a few months. What remains is your essential monthly spend.
Then pick the number of months
This is where your situation matters more than any rule of thumb. Here is how we usually think about it with families we work with:
| Your situation | Months of essential spend | Why |
|---|---|---|
| Two earners, both salaried, no dependants | 3 to 4 | One income can carry the house for a while |
| One salaried earner, spouse or children depend on you | 6 | A job search can take three to six months |
| Self-employed, commission or freelance income | 9 to 12 | Income can dip for several months together |
| Single-income home with ageing parents | 9 or more | Medical costs and income risk add up |
| Retired, living on pension or withdrawals | 12, plus health cover | No salary to rebuild the fund quickly |
Move up a row if your industry is going through layoffs, if your health cover is small, or if one family member has an ongoing medical condition.
A worked example
Rohit and Neha have one salary in the house, a seven-year-old and Rohit's mother living with them. Their essential costs each month:
- Rent and maintenance
- ₹18,000
- Groceries, milk and household help
- ₹11,000
- Electricity, gas, phone, internet
- ₹4,500
- School fees (yearly fee spread monthly)
- ₹6,000
- Medicines and check-ups for mother
- ₹3,000
- Insurance premiums (yearly spread monthly)
- ₹2,500
- Fuel and basic travel
- ₹5,000
- Essential monthly spend
- ₹50,000
Single income with a parent at home puts them at nine months: ₹50,000 × 9 = ₹4,50,000. If they can set aside ₹20,000 a month, it takes about 23 months to build. That is fine. A fund built over two years is far better than no fund.
Where to keep it
An emergency fund needs to be safe and quick to reach. Growth comes third. We usually suggest splitting it into layers:
- One month in your savings account. Reachable instantly by UPI or card, for the first bills.
- Two to three months in a sweep-in or short fixed deposit. Breakable the same day, with a small interest penalty.
- The rest in a liquid fund or overnight fund. Redemptions usually reach your bank account the next working day. Many liquid funds also offer instant redemption up to ₹50,000 a day (rules as of 2026, check current rules).
Keep it out of equity funds, small savings schemes with lock-ins, ELSS and anything that charges for early exit. An equity fund can be down 20% exactly in the month you need it, and that is the worst time to sell. Gains on liquid funds are taxed at your income slab rate (rules as of 2026, check current rules), so treat them as a parking spot, not an investment for growth.
Liquid fund values can also move slightly. Any return you see quoted is an assumed rate for illustration. Mutual fund investments are subject to market risks, read all scheme related documents carefully.
Health cover changes the number
A hospital bill is the most common emergency we see. With a family floater of ₹10 lakh or more, the fund only needs to handle the gaps: room-rent limits, co-pay, items not covered and the time before reimbursement. With no cover, one surgery can empty a fund that took years to build. If you do not have a policy yet, read our health insurance page before you add more months to the fund.
When to top it up
- Every time your rent, school fees or household costs go up, usually once a year
- After a child is born, or when a parent moves in with you
- When you move from a salaried job to running your own business
- Right after you use it, before starting any new SIP
Once the fund is full, stop adding to it and send the monthly saving to your long-term goals through a SIP. A fund that grows far beyond your needs is money sitting idle.
Three mistakes we see often
Counting the credit card limit. A card limit is borrowed money at a high cost, not a fund. Counting the PF balance. Partial PF withdrawals have conditions and take time. Keeping it in the same account you spend from. It gets used for a sale or a phone upgrade. A separate account or a liquid fund folio keeps it out of sight.
