Someone asked me recently whether they should put their Diwali bonus into an FD or start an RD. I asked them a question back — do you already have the money, or are you planning to save it over the next year? That one question usually settles it. FD and RD aren't really competing products, they solve two different problems, and most of the confusion comes from treating them as interchangeable.
Let me walk through how each actually works.
Fixed Deposit — for money you already have
An FD is simple: you hand the bank a lump sum today, pick a tenure (7 days to 10 years), and the bank pays you a fixed interest rate for that entire period. The rate is locked in on day one — even if the bank cuts rates for new depositors next month, your FD keeps earning what you were promised.
FDs suit money you already have sitting around — a bonus, maturity proceeds from another investment, an inheritance, or savings you've built up and now want to park safely. If you don't have the lump sum yet and are trying to build it up month by month, an FD isn't really the tool — that's what an RD is for.
Recurring Deposit — for building the habit
An RD works the opposite way. Instead of one lump sum, you commit to depositing a fixed amount every month — say ₹5,000 — for a chosen tenure, typically 6 months to 10 years. At the end, you get back your total deposits plus interest.
RDs are built for people who don't have a lump sum but can commit to a monthly saving habit — salaried employees saving for a specific goal (a vacation, a gadget, next year's school fees), or anyone who knows that if the money stays in a savings account it'll quietly get spent. The forced monthly commitment is the actual product here, not just the interest rate.
How the interest math actually differs
Both FD and RD typically compound quarterly at most Indian banks, but the outcome looks different because of when the money goes in.
In an FD, your entire principal earns interest from day one of the tenure. In an RD, your first month's deposit earns interest for the full tenure, but your last month's deposit earns interest for only one compounding period — because it's only been in the account a few weeks by the time the RD matures. This is why, for the same total amount invested and the same rate, an FD generally yields slightly more total interest than an RD — simply because more of your money has been earning interest for longer.
This isn't a flaw in RDs — it's just the mechanical reality of depositing gradually instead of all at once. The real benefit of an RD was never "beats FD on returns," it's that it gets you to save money you otherwise wouldn't have had to put into an FD in the first place.
Exact rates vary quite a bit by bank, tenure, and whether you're a senior citizen (who usually get a slightly higher rate on both products), and they change over time with RBI's repo rate cycle — so rather than quoting a number here that may be outdated by the time you read this, it's worth checking your bank's current card rate and running the numbers yourself.
Premature withdrawal — the part people forget to check
Life happens, and sometimes you need the money before maturity. Both FD and RD allow premature withdrawal at most banks, but commonly with a penalty — typically a reduction of around 0.5–1% off the interest rate that would otherwise have applied for the period the deposit actually stayed with the bank. Some banks also apply a minimum lock-in before they'll allow any premature closure of an RD, often around the first 3 months.
If there's a real chance you'll need the money early, it's worth reading the specific penalty clause for your bank and product before you commit — this detail varies enough between banks that assuming "it's probably similar everywhere" can cost you more than expected.
How FD and RD interest is taxed
This part is identical for both. Interest earned on FDs and RDs is fully taxable, added to your total income and taxed at your income tax slab rate — there's no special lower rate for deposit interest.
Banks are required to deduct TDS once your interest income from all FD/RD accounts with that bank crosses a threshold in a financial year — commonly ₹40,000 (₹50,000 for senior citizens), though this applies per bank, not per account, so having five small FDs at the same bank doesn't help you dodge it. If your total income is below the taxable threshold, you can submit Form 15G (or Form 15H if you're a senior citizen) to the bank to avoid TDS being deducted — but note that even without TDS, you're still legally required to report and pay tax on the interest if you're liable for it; Form 15G just stops the upfront deduction, it doesn't exempt the income.
So which one should you actually pick?
If you have a lump sum sitting idle right now and don't need it for a defined period, an FD puts it to work immediately and typically earns slightly more for the same total money. If you're starting from zero and the real challenge is building the discipline to save every month, an RD is the better tool — even if the final number is marginally smaller, you wouldn't have had that money saved up any other way.
A lot of people actually use both in sequence — RD to build up a corpus over a year or two, then move the RD maturity amount into an FD to keep earning on it without the temptation to spend it. There's nothing wrong with that approach.
