Key points
- FDs and RDs give guaranteed returns; equity SIPs give market-linked returns that can be higher or lower.
- ₹10,000 a month for 10 years: about ₹17.4 lakh in an RD at 7%, about ₹23.2 lakh in a SIP at an assumed 12%.
- FD and RD interest is taxed every year at your slab; equity fund gains are taxed only when sold, at lower rates.
- Match the product to the goal’s timeline: deposits for under 3 years, equity SIPs for 5+ years.
Three different tools
| Fixed deposit (FD) | Recurring deposit (RD) | Equity mutual fund SIP | |
|---|---|---|---|
| How you invest | One lumpsum | Fixed amount monthly | Fixed amount monthly |
| Returns | Fixed when booked | Fixed when opened | Market-linked, not guaranteed |
| Typical return | About 6%–7.5% | About 6%–7.5% | Long-run average often 10%–13%, with swings |
| Risk to capital | Very low; insured up to ₹5 lakh per bank | Very low; insured up to ₹5 lakh per bank | Value can fall, sometimes sharply |
| Early exit | Penalty, typically 0.5%–1% | Penalty on premature closure | Anytime; exit load if under ~1 year |
| Tax | Interest at slab rate each year | Interest at slab rate each year | 12.5% on long-term gains above ₹1.25 lakh a year |
₹10,000 a month: RD vs SIP
| Period | Invested | RD value | SIP value |
|---|---|---|---|
| 5 years | ₹6,00,000 | ≈ ₹7,19,300 | ≈ ₹8,24,900 |
| 10 years | ₹12,00,000 | ≈ ₹17,37,000 | ≈ ₹23,23,400 |
Over 10 years the SIP’s expected lead is large — but it is an expectation, not a promise. In a poor decade the SIP could end below the RD. Over five years the gap is smaller and the range of SIP outcomes relatively wider.
Tax widens the gap
Deposit interest is added to your income every year and taxed at your slab — at the 30% slab plus cess, a 7% deposit yields only about 4.8% after tax, which is below typical inflation. Equity fund gains are taxed only when you sell, and long-term gains above ₹1.25 lakh a year are taxed at 12.5%. For someone in a high tax bracket with a long horizon, the after-tax difference can be substantial.
Choosing by goal
- Emergency fund: savings account, sweep FD or liquid fund — safety and access matter, not returns.
- Goals within 1–3 years (a car, a wedding, a fee payment): FD or RD, so the money is certainly there.
- Goals 3–5 years away: a mix, or hybrid and debt funds.
- Goals 5+ years away (retirement, children’s education): equity SIPs, gradually moving to safer options as the goal approaches.
A rough after-tax comparison
Taking the 10-year example and an investor in the 30% slab: RD interest is taxed every year, which lowers the effective rate to roughly 4.8%, so the RD ends near ₹15.4 lakh after tax. If the SIP achieves 12% and all units are redeemed at the end, long-term capital gains tax of about ₹1.3 lakh leaves roughly ₹21.9 lakh.
These are estimates. SIP returns vary widely from decade to decade, and spreading redemptions over several years, to use the ₹1.25 lakh exemption each year, reduces the tax further.
Using both together
This is rarely an either-or choice. A sensible plan often uses an RD or FD for the next one or two years of known expenses and an emergency fund, and SIPs for everything further out. As a long-term goal gets within two or three years, move money gradually from the SIP into deposits so a market fall just before the goal cannot derail it.
Frequently asked questions
Is a SIP risky?
A SIP in an equity fund carries market risk: its value can fall below the amount invested, especially over short periods. Over long periods, diversified equity funds have usually beaten deposits, but there is no guarantee.
Which is better for a 3-year goal?
For money you definitely need in three years, an RD, FD or short-term debt fund is usually more suitable than an equity SIP, because equity values can fall significantly in any given three-year period.
Are RD returns guaranteed?
Yes. The rate is fixed when you open the RD and does not change for its term. Deposits are insured by DICGC up to ₹5 lakh per depositor per bank.
