Fixed deposits remain popular among investors who want predictable returns without exposure to stock-market fluctuations. State Bank of India offers domestic term deposits across several maturity periods, with different interest rates for regular customers, senior citizens and super senior citizens.

Two short-term options that may interest depositors are a six-month FD and a 211-day FD. Although the difference between these tenures is only about one month, SBI places them in separate interest-rate brackets.

Here is a detailed look at the applicable rates and the approximate return on an investment of ₹1 lakh.

What Is the SBI FD Rate for Six Months?

SBI’s retail domestic deposit table places tenures ranging from 180 days to 210 days in one category. Therefore, an FD booked for exactly 180 days—or approximately six months—falls within this slab.

For retail deposits below ₹3 crore, the applicable annual interest rates are:

Customers aged 80 and above receive an additional 0.10 percentage point over the senior-citizen rate under SBI Patrons, subject to the scheme’s terms.

How Much Can ₹1 Lakh Earn in a Six-Month SBI FD?

For an illustrative calculation, assume that ₹1 lakh remains invested for 180 days. Using the applicable annual rate on a simple pro-rata basis, the estimated return would be:

These figures are estimates. The bank’s actual maturity calculation may differ slightly because of its interest-calculation method, compounding rules, booking date and the exact number of days in the deposit.

What Is the SBI Interest Rate for a 211-Day FD?

A deposit of exactly 211 days moves into SBI’s next interest-rate slab, which covers tenures from 211 days to less than one year.

The applicable rates for retail deposits below ₹3 crore are:

Compared with a 180-day deposit, the 211-day option provides both a longer investment period and a higher annual rate.

How Much Will ₹1 Lakh Grow in 211 Days?

Using the same simple pro-rata method, the estimated returns on ₹1 lakh invested for 211 days would be:

The estimated interest is calculated before any applicable tax deduction. The final amount credited by SBI may vary marginally according to the product selected and the bank’s calculation method.

SBI’s official rate table lists 5.65% for regular customers and 6.15% for senior citizens on deposits of 180 to 210 days. For tenures beginning at 211 days and running to less than one year, the rates rise to 5.90% and 6.40%, respectively. These rates can be checked on the official SBI retail deposit page.

Why Do Super Senior Citizens Receive a Higher Rate?

Under the SBI Patrons deposit facility, eligible customers aged 80 or above receive an additional benefit of 10 basis points over the rate available to senior citizens.

One basis point is equal to 0.01 percentage point. Therefore, an additional 10 basis points raises a rate of 6.40% to 6.50%.

The higher rate is subject to SBI Patrons’ eligibility and product conditions. SBI states that the additional benefit does not apply to certain products, including recurring deposits, tax-saving deposits, non-callable term deposits and some other specified deposit categories. Customers can review the conditions on the SBI Patrons information page.

Can Investors Deposit Up to ₹3 Crore at These Rates?

The rates discussed above apply to SBI retail domestic term deposits of less than ₹3 crore. A deposit of ₹3 crore or more is treated as a bulk term deposit and may carry a different interest rate.

This means the upper limit for remaining within the retail category is any eligible amount below ₹3 crore. Investors planning to place a substantial sum should confirm whether their deposit will be classified as retail or bulk before booking it.

Six Months or 211 Days: Which Tenure Offers a Better Return?

The 211-day FD provides a higher estimated return because the money remains invested for 31 additional days and receives a higher annual interest rate.

For a regular customer investing ₹1 lakh, the illustrative interest rises from approximately ₹2,786 for 180 days to ₹3,411 for 211 days. That is an estimated difference of about ₹625.

A senior citizen could earn approximately ₹667 more by choosing 211 days instead of 180 days, while the estimated difference for a super senior citizen is around ₹676.

However, the longer tenure is suitable only if the depositor is unlikely to need the funds during those additional days. Prematurely closing the FD may reduce the effective interest rate and could attract a penalty under SBI’s rules.

Tax Treatment of SBI FD Interest

Interest earned from a fixed deposit is generally taxable according to the depositor’s applicable income-tax provisions. SBI may deduct tax at source when the prescribed conditions and thresholds are met.

Eligible depositors may submit the relevant declaration form to request non-deduction of TDS, provided they satisfy the applicable rules. A person should not assume that non-deduction of TDS makes the interest tax-free. The income may still need to be reported in the tax return.

What to Check Before Booking the FD

Interest rates can change at the bank’s discretion. The rate applicable to a new deposit is generally the rate available on its booking date.

Before investing, customers should verify:

• The latest annual interest rate
• The exact maturity date and amount
• Premature-withdrawal conditions
• Auto-renewal instructions
• Interest-payment frequency
• Nomination details
• TDS and tax implications

Final Takeaway

For retail domestic deposits below ₹3 crore, SBI offers 5.65% to regular customers on a six-month FD and 5.90% on a 211-day deposit. Senior citizens receive 6.15% and 6.40%, respectively, while eligible customers aged 80 or above may receive 6.25% and 6.50%.

On an illustrative investment of ₹1 lakh, the estimated interest is approximately ₹2,786 for 180 days and ₹3,411 for 211 days for a regular customer. Actual returns should always be confirmed through SBI’s official maturity calculation before investing.
