SBI FD Returns on ₹1 Lakh: What 1, 3, 5 and 10 Years Can Earn a Saver

A fixed-deposit calculator story from economictimes.com has put a simple question to savers: what does ₹1 lakh placed in a State Bank of India fixed deposit grow to after 1, 3, 5 and 10 years? The answer depends on the interest rate and compounding, and on how long the money stays put.

The short version for readers: the longer you stay invested, the more compounding does the work, and a 10-year deposit can come close to doubling the principal at mid-single-digit rates. BankCreds has not reproduced the outlet's numbers. Below we explain the arithmetic and use clearly labelled illustrative rates so you can check your own case.

Before you act on any projection, remember that the rate you actually get is the one printed on your deposit receipt on the day you book it, not the one in a calculator example.

Key takeaways

• According to reporting by economictimes.com, an SBI FD calculator shows what ₹1 lakh can grow to over 1, 3, 5 and 10 years.
• At an illustrative 6.5% a year with quarterly compounding, ₹1 lakh becomes about ₹1.07 lakh in 1 year and about ₹1.91 lakh in 10 years.
• Interest on an FD is taxable at your slab rate, so the post-tax return can be well below the headline rate.
• Deposit insurance covers up to ₹5 lakh per depositor per bank, including principal and interest.
• Pick the tenure from when you need the money, not from the largest figure in a calculator.

How an SBI fixed deposit actually grows

A fixed deposit pays a stated annual interest rate for a chosen period. In a cumulative deposit, the interest is not paid out; it is added back to the principal, and the next interest calculation runs on the larger amount. Banks in India typically compound deposit interest quarterly, so each year contains four small additions rather than one.

The formula is maturity = principal × (1 + r/4)^(4 × years), where r is the annual rate as a decimal. A calculator simply runs this for you. The two inputs that matter most are the rate and the tenure; the compounding frequency is a smaller but real third factor.

If you choose a non-cumulative or payout option instead, interest is credited to your account monthly, quarterly or yearly and the principal stays at ₹1 lakh. You then have regular income but no compounding unless you reinvest it yourself.

What ₹1 lakh can become: an illustrative table

The economictimes.com piece works from SBI's own rate card. We do not have those rate figures here, so the table below uses a round, assumed 6.5% a year with quarterly compounding. Treat it as a method demonstration, not as SBI's quoted rate or as the outlet's numbers.

Tenure	Approx. maturity value (₹)	Approx. interest earned (₹)
1 year	1,06,659	6,659
3 years	1,21,334	21,334
5 years	1,38,028	38,028
10 years	1,90,517	90,517

Notice that the 10-year interest is not twice the 5-year interest; it is more than double. That is compounding: later years earn interest on earlier interest. The effective yield on the 6.5% quarterly-compounded deposit works out to roughly 6.66% a year.

How much the rate itself matters

Small differences in rate compound into noticeable rupee gaps over time. Using the same ₹1 lakh for 5 years with quarterly compounding, here is how three assumed rates compare.

Assumed annual rate	Approx. value after 5 years (₹)	Gap versus 6% (₹)
6.0%	1,34,686	0
6.5%	1,38,028	3,342
7.0%	1,41,487	6,801

A half-point gap is worth a few thousand rupees on ₹1 lakh over five years. On ₹10 lakh the same gap is ten times larger, which is why it pays to compare current offers on the interest rates page before booking a large deposit. Senior citizens are usually offered a rate that is typically around half a percentage point higher than the general rate, so the table shifts upward for them.

Tax: the gap between headline and take-home

FD interest is added to your income and taxed at your slab rate. For cumulative deposits the interest is generally taxable each year as it accrues, even though you receive nothing until maturity. That surprises many first-time depositors.

Take the one-year illustration of ₹6,659 interest. A saver in the 30% slab, with 4% cess, pays roughly 31.2% of that, about ₹2,078, leaving around ₹4,581. The post-tax yield is near 4.6%, not 6.5%. A saver whose income is below the taxable limit keeps the whole amount.

Banks also deduct TDS once annual interest at that bank crosses a threshold. Thresholds have been revised in recent years and differ for senior citizens, so check the current figure with your bank. If your total income is below the taxable limit, you can submit the relevant declaration form to prevent unnecessary deduction. If TDS is cut anyway, you can claim it back when filing your return.

Safety, liquidity and premature withdrawal

Bank deposits in India are insured by the Deposit Insurance and Credit Guarantee Corporation (DICGC) up to ₹5 lakh per depositor per bank, covering principal and interest together. A deposit in a large public sector bank also carries the comfort of its size, but the insurance rule is the same for every insured bank. If you hold more than ₹5 lakh across all deposits at one bank, the excess is not covered by that scheme.

Liquidity is the trade-off. You can usually break an FD early, but banks commonly deduct a penalty from the interest rate, often somewhere around half to one percentage point, and pay the rate applicable for the period actually run. On a 10-year deposit broken in year four, that can noticeably reduce what you take out.

Who this suits and who should look elsewhere

An FD suits a saver with a known future expense, a low tolerance for market swings, or a need for steady income, such as a retiree. It also suits an emergency fund top-tier slice that you do not want to touch daily.

It suits less well a young saver with a 15-year horizon and no near-term need for the money, or a high-slab taxpayer for whom post-tax returns barely beat inflation. For those readers, the calculator figure is a floor-style comparison point, not a recommendation to lock everything in.

If you are borrowing as well as saving, remember that an FD earning around 6.5% before tax while you carry a loan at a much higher rate is usually a poor combination. Compare the interest you save by prepaying with the post-tax interest the deposit earns, using the EMI calculator to see the real cost of the loan.

How to use an FD calculator well

A calculator is only as good as its inputs. Follow these steps before trusting a result:

1. Confirm the bank's current rate for the exact tenure and for your category (general or senior citizen).
2. Select cumulative or payout, since the maturity figure only applies to cumulative.
3. Check the compounding frequency used by the calculator.
4. Subtract tax at your slab rate to see the post-tax value.
5. Compare the result with at least one other bank's rate on the same day.

And avoid these common mistakes:

• Assuming the 10-year rate will stay available; renewals are priced at the rate on the renewal date.
• Putting everything into one long deposit and then needing cash early.
• Ignoring tax on accrued interest.
• Holding more than the insured limit at a single bank without thinking about it.

Outlook: what could change the numbers

Bank deposit rates follow the broader interest rate cycle set by the Reserve Bank of India's policy stance and by banks' own funding needs. When the policy rate falls, deposit rates generally drift lower over the following months; when it rises, they tend to follow. A calculator example is therefore a snapshot.

The sensible way to read stories like this one is as a quick sense of scale: ₹1 lakh in an FD roughly grows by a few thousand rupees in year one and by a larger multiple over a decade. It is not a forecast, and it should not be the only input when deciding where your savings go.

Frequently asked questions

How much will ₹1 lakh in an SBI FD become after 5 years?

It depends on the rate on the day you book. At an illustrative 6.5% with quarterly compounding, ₹1 lakh grows to about ₹1.38 lakh in 5 years. Use the bank's current rate card for the real figure.

Is the interest on a fixed deposit taxable?

Yes. FD interest is added to your income and taxed at your slab rate, and cumulative-deposit interest is generally taxable each year as it accrues. Banks may deduct TDS above a threshold, which you can claim back in your return if your tax liability is lower.

Is my money safe in a bank FD?

Deposits in insured banks are covered by DICGC up to ₹5 lakh per depositor per bank, including principal and interest. Amounts above that at the same bank are not covered by this scheme.

Can I withdraw an FD before maturity?

Usually yes, but banks commonly charge a penalty and pay interest at the rate for the period actually held. Check the exact penalty before booking, especially for long tenures.

Is a 10-year FD better than a 5-year FD?

Not automatically. A 10-year deposit compounds longer but locks in today's rate and reduces flexibility. Choose the tenure based on when you will need the money and your view on future rates.
