You’ve decided to save every month. Great. Now comes the next question: where should that money go? For most Indians, the choice comes down to three options – a recurring deposit (RD), a fixed deposit (FD) or a mutual fund SIP. Each is right for a different kind of goal. Here’s how to choose.
The Three Options in One Line Each
- RD: you deposit a fixed amount every month and earn guaranteed interest.
- FD: you deposit a lump sum once and earn guaranteed interest.
- SIP: you invest a fixed amount every month in a mutual fund; returns depend on the market.
How They Compare
| RD | FD | Equity SIP | |
|---|---|---|---|
| How you invest | Monthly | Lump sum | Monthly |
| Returns | Fixed, about 6–7.5% | Fixed, about 6–7.5% | Market-linked |
| Risk | None | None | Can fall in the short term |
| Tax | Interest taxed at your slab rate every year | Interest taxed at your slab rate every year | 12.5% on long-term gains above ₹1.25 lakh a year, only when you sell |
| Access | Early closure with a penalty | Early closure with a penalty | Anytime (some funds charge a small exit load in year one) |
| Best for | Short-term goals, saving from salary | Parking a lump sum safely | Long-term goals, 5+ years |
The Numbers: ₹5,000 a Month for 5 Years
| Option | Total Invested | Value After 5 Years |
|---|---|---|
| Post Office RD (6.7%) | ₹3,00,000 | ₹3,56,829 – guaranteed |
| Equity SIP (10%, illustrative) | ₹3,00,000 | About ₹3,90,412 – not guaranteed |
| Equity SIP (12%, illustrative) | ₹3,00,000 | About ₹4,12,432 – not guaranteed |
Over 10 years, the gap widens: ₹5,000 a month grows to about ₹8.69 lakh in an RD at 7%, versus about ₹11.62 lakh in a SIP at 12%. That’s the power of equity compounding – but only if you can stay invested through the market’s bad years.
What About an FD?
If you already have ₹3 lakh today, an FD at 7% for 5 years grows to about ₹4,24,433 – more than the RD, because all your money starts earning interest from day one. So: have a lump sum? Choose an FD. Saving from your monthly salary? Choose an RD.
Match the Option to Your Goal
| When You Need the Money | Best Choice | Why |
|---|---|---|
| Within 1 year | Savings account, FD or liquid fund | Safety and easy access matter most |
| 1–3 years | RD or FD | Guaranteed returns; markets are too unpredictable over this period |
| 3–5 years | A mix, or a hybrid fund | Some growth, with a cushion against market falls |
| 5+ years | Equity SIP | Time smooths out market ups and downs, and growth beats inflation |
Examples: a wedding next year – RD. A car in two years – RD or FD. Your child’s college in 12 years – SIP. Retirement in 25 years – SIP (plus PPF or NPS).
Don’t Forget Tax and Inflation
RD and FD interest is taxed every year at your slab rate. In the 30% slab, a 7% deposit effectively earns under 5% after tax – roughly the same as inflation. That’s fine for short-term safety, but it means deposits barely grow your money’s real value over the long run. Equity SIPs are taxed only when you sell, and only on gains above ₹1.25 lakh a year at 12.5%.
The Simple Answer
You don’t have to pick just one. A sensible plan: keep an emergency fund in a savings account or FD, use RDs for goals within 3 years, and run SIPs for everything 5+ years away. Run your own numbers:
