RBI Floating Rate Bonds vs SBI 7-Year FD: Which Fits Your ₹10 Lakh?

A report by Trade Brains compares RBI Floating Rate Savings Bonds with a 7-year SBI fixed deposit (FD). It says ₹10 lakh could grow to ₹15.63 lakh over seven years.

For you, the big lesson is simple. The two products work in different ways. Don't compare only the final number. Look at how interest is paid, how it's taxed and whether the rate can change.

Key takeaways

• The ₹15.63 lakh figure, as reported, equals about 6.6% a year with yearly compounding.
• A floating bond's rate can change every six months. A fixed deposit's rate is locked.
• Bond interest is paid out regularly. A cumulative FD adds interest back to your money.
• Interest from both is taxable, so your tax slab changes your real gain.
• Pick based on your need for income, safety and a firm end amount.

How floating rate bonds and FDs work

A floating rate savings bond is a government-backed bond. In its earlier form, it ran for seven years. Its rate was linked to another small-savings rate and reset twice a year. So your rate can rise or fall while you hold it.

Interest on these bonds was paid out every six months. It wasn't added back to your investment. If you want growth, you must reinvest that money yourself.

An FD is different. You pick a bank and a term. The bank fixes the rate on the day you book it. With the cumulative option, interest is added back and earns more interest. That's compounding.

What ₹15.63 lakh means in rupees

Let's test the number. If ₹10 lakh grows at about 6.6% a year, compounded yearly, the balance builds up like this. These are our own estimates, not figures from the report.

Year	Approximate balance (₹ lakh)
1	10.66
3	12.11
5	13.76
7	15.63

So your gain over seven years is about ₹5.63 lakh. Most of that comes in the later years. That's the power of compounding.

Now think about a bond that pays interest out. At 6.6%, you'd get about ₹66,000 a year on ₹10 lakh. That's about ₹33,000 every six months. You'd only match the table if you reinvested every payout at the same rate.

Who is affected

Three groups should pay attention:

• Retirees: Regular payouts can help with monthly costs. A cumulative FD won't pay you until the end.
• Long-term savers: If you don't need cash for seven years, compounding helps you.
• High-tax savers: Interest is added to your income and taxed at your slab rate. Banks may also cut tax at source (TDS) on FD interest.

Safety is another point. Bank deposits are insured by DICGC up to ₹5 lakh per depositor per bank. A government bond works on a different backing. Read the rules of each product before you invest.

What to do now

Before you move any money, run through this short checklist:

1. Decide if you need regular income or one lump sum at the end.
2. Check your tax slab and estimate the tax on yearly interest.
3. Confirm whether the bond is open for fresh buying right now.
4. Ask about early exit rules. Both options can lock your money for years.
5. Keep your emergency fund separate, in an easy-access account.

Frequently asked questions

Is the floating rate bond rate fixed for seven years?

No. The rate is reset every six months. It can go up or down during the term, so your final return isn't certain.

Does an FD always give a higher final amount than a bond?

Not always. It depends on the rates at the time, how often interest compounds and whether you reinvest bond payouts. Compare the same rupee amount and the same term.

Is the interest on these options tax-free?

No. Interest from both is taxed as income at your slab rate. Check your own tax position before you choose.
