SIP vs RD
A recurring deposit and a SIP work the same way: a fixed amount, every month, for a fixed term. That makes this the cleanest comparison on this site — the only variables are the return and whether it is guaranteed.
What is identical
Both take a fixed monthly amount by mandate. Both run for a term you choose. In both, your first instalment is invested for the full term and your last for a single month, so both have the same "average money invested for about half the period" characteristic.
An RD even uses the same annuity shape as a SIP, with quarterly compounding instead of monthly:
M = Σ P × (1 + r ÷ 4)(n − k + 1) ÷ 3. Structurally these are the same
instrument with different engines.
Which means the comparison cannot be muddied by timing or structure, the way SIP-versus-lump-sum can. It is purely about return and certainty.
What differs, in rupees
| Term | Deposited | RD (guaranteed) | SIP (projected) | SIP ahead by |
|---|---|---|---|---|
| 3 years | ₹1.8 L | ₹2,00,686 | ₹2,17,538 | 8% |
| 5 years | ₹3 L | ₹3,59,664 | ₹4,12,432 | 15% |
| 10 years | ₹6 L | ₹8,68,509 | ₹11,61,695 | 34% |
| 15 years | ₹9 L | ₹15,88,411 | ₹25,22,880 | 59% |
| 20 years | ₹12 L | ₹26,06,913 | ₹49,95,740 | 92% |
At three years the SIP's projected advantage is around 8% — nowhere near enough to justify risking capital you need in three years.
At twenty years it is around 92%, and that is before tax, which pushes it further apart: RD interest is taxed at your slab every year, while long-term equity gains are taxed at 12.5% above the ₹1.25 lakh annual exemption, and only when you sell.
How to decide, in one question
When do you need this money?
Within three years: RD. The guaranteed amount is worth more than the expected extra, and a 25% drawdown six months before your deadline has no recovery path.
Beyond seven years: SIP. The gap becomes large enough that choosing certainty is an expensive decision, and the horizon gives volatility time to resolve.
Three to seven years: genuinely ambiguous. A hybrid fund, or splitting between both, is a reasonable answer.
Nothing else about the choice matters as much as the deadline.
Two practical differences worth knowing
Missing an instalment. An RD normally charges a penalty per missed instalment and can be closed after repeated misses, paying out at a reduced rate. A SIP simply buys no units that month, with no penalty from the fund. If your income is irregular, that flexibility is a real advantage.
Breaking it early. An RD closed early pays the rate applicable to the period it actually ran, minus a penalty. A SIP has no such concept — you redeem units at the prevailing NAV, which may be higher or lower than you paid, and possibly an exit load if you are inside a year.
Questions people actually ask
Is an RD better than a SIP for short-term goals?
Yes, clearly, for anything inside about three years. The RD's maturity value is contractual and an equity SIP's is not, and no averaging benefit compensates for a bad market in the month you need the money.
Why does my RD earn less than an FD at the same rate?
Exposure time. In an FD the whole amount is invested from day one; in an RD each instalment arrives later than the last, so the average money is invested for about half the term.
Same reason a SIP trails a lump sum, and it has nothing to do with the rate.
Can I run both at once?
Yes, and for most people that is the sensible arrangement — an RD for near-term goals and the emergency buffer, a SIP for anything long-term.
They are tools for different deadlines rather than competitors.
Is RD interest taxed like FD interest?
Yes, identically: added to your income at your slab rate, on accrual, with TDS above the threshold. There is no separate or concessional treatment for recurring deposits.
