How Much Should Your Emergency Fund Be?
Straight answer: for a salaried person in a stable, dual-income household, three to six months of essential expenses. For a single earner or someone with a large variable component in their pay, six to nine. For the self-employed, freelancers and anyone on commission, nine to twelve. For a retired household with no active income, twelve to twenty-four months held separately from the retirement corpus.
Those are planning conventions, not rules, and this calculator says so on the face of it. What the calculator does is turn whichever band fits you into a rupee number, measure it against what you already hold, and tell you the monthly amount that closes the difference in a timeframe you choose.
Method
Three conventions worth stating plainly.
- Essential expenses, not total spending. Include rent or home loan EMI, groceries, utilities, school fees, insurance premiums, other loan EMIs and regular medicines. Exclude holidays, restaurants and discretionary shopping — in a real emergency those stop.
- Dependants widen the band, they do not multiply it. One extra month per dependant, capped at three. A larger household raises the floor because more people rely on the same income, but the fund is still measured in months of spending, and the spending figure already reflects the household size.
- The midpoint is used for the rupee target, with the full range shown beside it. Aim at the upper end if your income is lumpy, your notice period is short, or your sector is cyclical.
The Bands, and Where They Come From
| Situation | Months of essential expenses | Why |
|---|---|---|
| Salaried, stable job, two incomes | 3 to 6 | One income can carry the household while the other is replaced |
| Single earner, or large variable pay | 6 to 9 | No second income to fall back on; bonus-heavy pay can vanish in a bad year |
| Self-employed, freelance, commission | 9 to 12 | Revenue is lumpy and a slow quarter is not the same as unemployment, but it feels like it |
| Retired, no active income | 12 to 24 | Nothing to replace, higher medical exposure, and selling assets in a bad market is the thing to avoid |
Add one month per dependant, up to three. A household supporting elderly parents alongside children sits at the top of its band rather than the bottom.
Worked Example
A single-earner household spends ₹60,000 a month on essentials and supports two dependants. The base band is 6 to 9 months; two dependants add two, giving 8 to 11 months, with a midpoint of 10.
Two and a half months of cover against a target of ten is the finding that matters. The monthly number is what turns it into a plan.
Where to Keep It
An emergency fund is not an investment. It is judged on how fast you can reach it and how certain the amount is, not on what it earns. In practice that means a sweep-in savings account, a short-tenure fixed deposit ladder, or a liquid or overnight fund — instruments where the money is available within a day and the value does not move much.
It should not sit in equity, in an ELSS with a lock-in, in a PPF account you cannot draw on, or in real estate. The whole point is that it is boring and available on the worst day of your year.
Once it is funded, stop adding to it and redirect the monthly amount into your actual goals — the goal planning calculator sizes those, and the SIP calculator projects what the redirected amount becomes.
Frequently Asked Questions
Yes. Loan repayments do not pause because your income did, and missing them damages your credit record on top of everything else. Include every EMI in the monthly figure.
No, it reduces one of the risks the fund covers. Insurance pays hospital bills, often after a delay and usually not in full. It does nothing about a lost job, a business downturn, an urgent trip home or a claim that gets rejected. Carry both.
They are a bridge, not a fund. Credit costs money exactly when you have least of it, and a limit can be cut at the bank’s discretion at the worst moment. Use them to smooth a gap of days, not to replace months of cover.
Generally yes. Cash held far beyond the target loses purchasing power every year — the inflation converter shows how much. Keep the target liquid and put the surplus to work.
Because the top of the range is a large number and an unreachable target tends to get abandoned. The midpoint is a realistic first destination and the full band is shown beside it so you can aim higher deliberately.
