You've decided to build a 6-month emergency fund - say ₹6L. Good. Now the question: where do you park it?
There are three sensible answers, and one wrong one.
The three real options
- FD ladder - 6 FDs of ₹1L each, maturing one per month.
- Liquid mutual fund - one lump-sum, redeemable in 24 hours.
- Sweep-in FD - auto-breaks FDs in ₹1K chunks to cover withdrawals.
The wrong answer: savings account (3–3.5% pre-tax). You're losing ~4% per year vs better alternatives, and savings account interest above ₹10K is taxable anyway.
Pre- and post-tax returns (30% slab)
| Option | Yield p.a. | Tax treatment | Post-tax yield | ₹6L after 1 yr |
|---|---|---|---|---|
| Savings account | 3.0% | Slab (above ₹10K) | 2.1% | ₹6.13L |
| Sweep-in FD | 6.5% | Slab | 4.55% | ₹6.27L |
| FD ladder (SFB) | 7.8% | Slab | 5.46% | ₹6.33L |
| Liquid fund | 7.2% | Slab (post Apr-2023) | 5.04% | ₹6.30L |
After the 2023 tax change on debt funds, liquid fund and FD ladder are roughly tied post-tax. FD ladder edges ahead if you bank with a small-finance bank (Equitas, Ujjivan, Suryoday) offering 7.5–8%.
Speed of access (when you actually need it)
| Option | Speed to cash | Breakage cost | Weekend/holiday? |
|---|---|---|---|
| Savings account | Instant | Zero | Yes |
| Sweep-in FD | Instant (auto-breaks) | 0–0.5% penalty | Yes |
| FD ladder | T+0 to T+1 | 0.5–1% penalty if broken | No (breaking needs branch/app) |
| Liquid fund | T+1 (or T+0 instant up to ₹50K) | Zero | No, markets closed |
For genuinely urgent needs (<24h), sweep-in is hard to beat. FD ladder works if your next rung matures on time or you're willing to break one.
The hybrid you should actually use
Here's the structure we recommend for a ₹6L emergency fund:
- ₹50K in savings / sweep-in - instant access, zero friction. Handles the 90% of events under ₹50K.
- ₹3L in liquid fund - T+1 access, modest post-tax return. Handles most medical events within a day.
- ₹2.5L in FD ladder (5 × ₹50K, 1-5 month maturities) - highest post-tax yield on the bulk. One rung matures each month, so liquidity is rolling.
An emergency fund's job is to be there in a bad month - not to outperform Nifty. Optimise for speed first, yield second, complexity never.
