Every Indian family investing across mutual funds, fixed deposits, and PPF eventually asks the same question: are we actually placing money in the right place, or did we just start each of these at different points in life and never revisit the mix?
There’s no single right answer — but there is a clear, factual way to think about it. This guide walks through how mutual funds, FDs, and PPF actually work: their liquidity, their tax treatment, and where each tends to fit in a family’s financial picture. No return promises, no “best investment” claims — just the mechanics, so you and your family can reason about it together.
The three instruments, in plain terms
Mutual funds pool money from many investors and invest it in stocks (equity funds), bonds and government securities (debt funds), or a mix of both (hybrid funds). You can invest as a lump sum or through a Systematic Investment Plan (SIP), and units can usually be redeemed on any business day, subject to the fund’s exit load rules.
Fixed deposits (FDs) are a fixed-tenure deposit with a bank or NBFC at a pre-agreed interest rate. You lock in a sum for a chosen period — anywhere from 7 days to 10 years — and the bank pays interest at maturity or at a chosen frequency.
Public Provident Fund (PPF) is a government-backed long-term savings scheme, opened through a bank or post office, with a fixed statutory tenure and interest rate that is revised quarterly by the government.
Liquidity: how fast can you actually get the money out?
This is often the deciding factor for families, and it’s where these three instruments differ the most.
Mutual funds are the most liquid of the three. Most open-ended funds allow redemption on any business day, with proceeds typically credited within 1–3 working days (equity funds) or on the same/next day (liquid/debt funds), though some funds apply a short-term exit load if redeemed within a specified period.
FDs sit in the middle. You can break a fixed deposit before maturity, but banks typically charge a penalty (commonly 0.5%–1% lower interest) for premature withdrawal, and the exact terms vary by bank.
PPF is the least liquid by design. It has a 15-year lock-in period. Partial withdrawals are allowed starting from the 7th financial year, and — following a Budget 2026 change — this window has moved earlier, to the 4th financial year, giving account holders some liquidity sooner without breaking the long-term structure. Full withdrawal is only available at maturity, or through account closure in specific circumstances (like medical emergencies) permitted by the scheme rules.
Taxation: what you actually keep matters
Tax treatment is where families most often get surprised, because it’s rarely explained clearly at the point of investing.
Mutual funds are taxed based on the fund type and holding period:
- Equity mutual funds: gains held for more than 12 months are long-term capital gains (LTCG), taxed at 12.5% on gains above ₹1.25 lakh in a financial year. Gains from units held for 12 months or less are short-term capital gains (STCG), taxed at 20%.
- Debt mutual funds bought on or after April 1, 2023: all gains, regardless of how long you hold the units, are taxed as short-term capital gains at your applicable income tax slab rate. Debt fund units purchased before that date retain long-term treatment (12.5% for holdings over 24 months).
Fixed deposits are the simplest, but not necessarily the most tax-efficient. FD interest is fully taxable as “Income from Other Sources” at your income tax slab rate — there’s no separate lower rate for long-held deposits. Banks deduct TDS at 10% once your total interest from that bank crosses ₹50,000 in a financial year (₹1,00,000 for senior citizens); this rises to 20% if you haven’t submitted your PAN. From April 2026, a new consolidated declaration form (Form 121) replaces the older Form 15G/15H process for claiming TDS exemption when your income is below the taxable threshold.
PPF is the most tax-efficient of the three by structure: it’s a fully “EEE” (Exempt-Exempt-Exempt) instrument. Contributions up to ₹1.5 lakh a year qualify for deduction under Section 80C, the interest earned is entirely tax-free, and the maturity amount is tax-free as well. The current PPF interest rate is 7.1% per annum (Q2 FY2026-27), compounded annually, unchanged since April 2020 — though it’s revised quarterly and isn’t guaranteed to stay at this level.
So which one is “better”?
There isn’t a single winner — each instrument is solving a different problem, and most families end up needing all three, just in different proportions depending on the goal:
- Money you might need in the next 1–3 years (an emergency fund, a planned expense) generally needs to sit somewhere liquid and low-volatility — this is where FDs and debt mutual funds are typically compared, weighing FD’s fixed, predictable payout against a debt fund’s flexibility and different tax treatment.
- Money for goals 15+ years away (retirement, a child’s higher education) is where PPF’s lock-in stops being a drawback and becomes a feature — it enforces the discipline of not touching long-term savings, on top of its tax efficiency.
- Money meant to be invested for growth over 5+ years, where you’re comfortable with market ups and downs along the way, is the typical context in which families weigh equity mutual funds — understanding that, unlike FDs and PPF, mutual fund returns are market-linked and not fixed or assured.
The honest starting point isn’t “which instrument is best” — it’s “what is this specific pool of money for, and when will we need it.” Time horizon and liquidity need almost always point to an answer before returns even enter the conversation.
The part families usually get wrong: not the choice, the visibility
In practice, most Indian families don’t have one big allocation decision to make — they have SIPs sitting in one app, an FD in one bank, a spouse’s FD in another, and a PPF account opened years ago that nobody has logged into recently. The instruments themselves are usually reasonable. What’s missing is a single view of how much sits where, and whether the overall mix still matches the family’s goals today.
That’s a visibility problem, not an investment-picking problem — and it’s worth solving before optimising further. Famli, for instance, is built to pull together accounts like these — mutual funds, FDs, and other synced holdings — into one dashboard via the RBI-regulated Account Aggregator framework, so families can see the full picture without manually updating a spreadsheet every quarter.
Frequently asked questions
Is PPF better than FD for long-term savings?
PPF offers a fully tax-free return structure (EEE) and a government-backed rate, while FD interest is taxed at your slab rate. For money you won’t need for 15 years, PPF’s tax treatment is generally more efficient — but its 15-year lock-in makes it unsuitable for shorter-term goals, where FDs offer more flexibility.
Are mutual fund gains taxed every year, even if I don’t sell?
No. Mutual fund taxation applies only when you redeem (sell) units and realise a gain. Simply holding units, or seeing their value rise on paper, does not trigger tax.
Can I withdraw from PPF before 15 years?
Partial withdrawals are permitted starting the 4th financial year after account opening (per Budget 2026 changes, moved up from the earlier 7-year rule), subject to scheme limits. Full withdrawal is only available at maturity or under specific permitted circumstances.
Does FD interest get taxed even if I don’t withdraw it?
Yes. FD interest is taxed on an accrual basis each financial year (or on payout, depending on how you report it), regardless of whether you withdraw the amount or let it reinvest.
