It will earn less than everything else you ever buy. It exists so that nothing else you buy ever has to be sold on a bad day.
Short answer: target 3–6 months of expenses — expenses, not salary: a fresher spending ₹25,000 a month needs ₹75,000–₹1.5 lakh, not multiples of CTC. Park it split between a savings account (one month) and a sweep-in FD or liquid fund (the rest) — instantly reachable, modestly earning, never equity. Build it before the first SIP: an investor without a cash buffer is one hospital bill away from selling units in a crash.

Count your real monthly burn — rent, food, transport, the family transfer, the subscriptions — and multiply by three to six. Three suits a fresher with employer health cover, no dependents and a family fallback; six suits anyone supporting parents, on probation, or in a volatile industry. The number recalibrates every time life changes — the fund that covered a bachelor sharing a flat does not cover the same person two years later with a spouse and a bigger kitchen. What it never includes: the goal money (that has its own accounts) or "spare" investing cash. This is insurance shaped like a bank balance.
| Layer | Amount | Vehicle | Why |
|---|---|---|---|
| Instant | ~1 month of expenses | Savings account | Reachable at 2 a.m., no questions |
| Near-instant | The remainder | Sweep-in FD or a liquid fund | Earns FD/overnight rates; redeems same-day or next-day; breaking a sweep FD costs pennies, not penalties |
| Never | — | Equity, ELSS, crypto, gold, a friend's startup | An emergency fund that can be down 30% during an emergency is a decoration |
On a ₹1.2 lakh fund, the sweep layer at ~6.5% earns roughly ₹6,500 a year on its ₹1 lakh — trivial next to your SIP's ambitions, which is the point. This money is optimised for availability, and 6.5% for guaranteed availability is a fine trade. (Interest is taxable, but a fresher under the rebate line owes nothing on it anyway.)
Why fund this before the first SIP, when equity "obviously" earns more? Because the alternative fails exactly when it matters: the fresher who SIPs from month one and meets a ₹60,000 dental emergency in a market drawdown sells units at the bottom, pays exit loads and short-term capital-gains tax, and learns to distrust equity — a triple loss the boring fund prevents entirely. Build the buffer in 4–8 months of aggressive saving (it is a sprint, not a lifestyle), then redirect the whole monthly amount into the SIP permanently. The fund also quietly buys the thing money is actually for at 23: the ability to leave a bad job without a spreadsheet of dread.
Define "emergency" before one arrives: job loss, medical, urgent family, essential repair — yes; a sale, a trip, a wedding gift, "the market dip" — no. Refill it first after any use, before SIPs resume. And resist upgrading it forever: past six months of expenses, additional cash is drag, not safety — that surplus belongs in real investments.
Three to six months of actual expenses — not salary. Someone spending ₹25,000 a month is building toward ₹75,000–₹1.5 lakh, leaning higher with dependents or job uncertainty and lower with solid family backup and employer health cover.
Split it: about one month's expenses in the savings account, the rest in a sweep-in FD or liquid fund. The test is same-day access without meaningful penalty — which is exactly what equity and locked products fail.
Fund first, sprint-style, over a few months — then convert the entire saving habit into the SIP. Investing without a cash buffer means any emergency forces you to sell investments at whatever price that week offers.
A sweep-in FD is ideal — it auto-breaks in units when the savings balance runs short, costing only a little interest on the broken portion. A regular FD works too; premature closure penalties are small next to the fund's purpose.
