How to Use This Calculator

FRSB Returns tab

Enter your investment amount (minimum ₹1,000, no upper limit) and the current FRSB interest rate (8.05% for Jan–Jun 2026). The calculator shows your semi-annual interest payout (paid on 1 January and 1 July), annual income, total interest over 7 years, and maturity value. It also displays the rate reset schedule, premature exit rules for senior citizens, and TDS applicability.

Tax Impact tab

Enter your annual FRSB interest, other income (salary, pension, FD interest, rent), and select your tax regime. The calculator computes the marginal tax on your FRSB interest, post-tax effective return, and TDS reconciliation. Key insight: FRSB has NO Section 80C deduction — the full interest is taxable under both old and new regimes.

FRSB vs PPF vs SCSS vs NSC tab

Enter an investment amount and your tax slab to compare post-tax returns across four government-backed instruments. The comparison factors in investment caps (PPF ₹1.5L/yr, SCSS ₹30L), tax treatment (PPF is tax-free, SCSS and NSC offer 80C), and different tenures. This helps you decide where to park your savings for the best after-tax returns.

The Formula

FRSB interest is calculated on a simple interest basis and paid semi-annually. The interest is NOT reinvested or compounded:

Semi-Annual Interest Payout:
Semi-Annual Interest = (Investment × Annual Rate) / 2

Where:
Investment = Lump sum amount (min ₹1,000, no upper cap)
Annual Rate = NSC rate + 0.35% = 7.70% + 0.35% = 8.05% (Jan–Jun 2026)

Annual Interest:
Annual Interest = Investment × Annual Rate / 100

Total Interest (7 years, assuming constant rate):
Total Interest = Annual Interest × 7

Maturity Value:
Maturity Value = Investment + Total Interest

Rate Reset Formula:
FRSB Rate = Prevailing NSC Rate + 0.35%
Resets on: 1 January and 1 July each year

TDS (Section 193):
TDS at 10% if annual interest > ₹10,000
TDS at 20% if PAN not provided

Unlike NSC (which compounds) or PPF (which compounds and is tax-free), FRSB pays out interest semi-annually without reinvestment. The floating rate means your actual returns over 7 years will differ from projections if NSC rates change. Historically, NSC rates have been relatively stable (7.0%–8.0% range since 2016), so FRSB rates have varied between 7.35% and 8.35%.

Example

Priya — IT professional, ₹10,00,000 in FRSB for safety

Priya is 35, works in Bengaluru, and wants to park ₹10 lakh in a sovereign-backed instrument. She cannot use SCSS (under 60) and has already maxed out her PPF at ₹1.5 lakh/year. She chooses FRSB for the remaining amount. Her salary is ₹12,00,000/year and she is in the 30% tax slab (new regime).

Step 1: Calculate semi-annual interest

FRSB investment₹10,00,000
Interest rate8.05% p.a.
Semi-annual interest₹10,00,000 × 8.05% / 2 = ₹40,250
Annual interest₹80,500
Monthly equivalent~₹6,708

Step 2: Calculate tax impact

Annual FRSB interest₹80,500
Section 80C benefitNot available for FRSB
Tax at 30% slab (marginal)₹24,150
Post-tax annual interest₹56,350
Post-tax effective return5.64% p.a.

Step 3: Seven-year summary (constant rate assumed)

Total interest (7 years)₹5,63,500
Total tax on interest (7 years)₹1,69,050
Post-tax total interest₹3,94,450
Maturity value (pre-tax)₹15,63,500
TDS deducted per year₹8,050 (10% of ₹80,500)

Priya receives ₹40,250 every 6 months (~₹6,708/month equivalent). At the 30% slab, her post-tax effective return is 5.64%. While lower than PPF's 7.1% tax-free return, FRSB allows her to invest the full ₹10 lakh as a lump sum without the ₹1.5 lakh/year PPF cap. Over 7 years, she earns ₹5.64 lakh in gross interest, with ₹3.94 lakh remaining after tax.

FAQ

The FRSB 2020 (Taxable) interest rate for January–June 2026 is 8.05% per annum. This rate equals the prevailing NSC rate (7.70%) plus a fixed spread of 0.35 percentage points. The rate resets every 6 months on 1 January and 1 July. This bond replaced the erstwhile 7.75% GOI Savings (Taxable) Bonds, 2018 which were discontinued on 28 May 2020. The FRSB rate has been 8.05% since January 2024, as the NSC rate has remained at 7.70% since April 2023.
Eligible: Any resident Indian citizen (individual), either singly or jointly. Not eligible: NRIs, HUFs, trusts, or institutions. The minimum investment is ₹1,000 in multiples of ₹1,000, with no maximum limit. Bonds are issued in Bond Ledger Account (BLA) form only — no physical certificates. You can invest through designated banks (SBI, all nationalised banks, select private banks like HDFC Bank, ICICI Bank, Axis Bank) and Stock Holding Corporation of India (SHCIL). A joint holder is treated as nominee — the bond proceeds pass to the surviving holder on death of the first holder.
Yes, FRSB interest is fully taxable as “Income from Other Sources” at your applicable slab rate. No Section 80C deduction is available on the investment amount — this is a key disadvantage compared to PPF, SCSS, and NSC. TDS: From 1 October 2024, TDS at 10% is deducted under Section 193 if annual interest exceeds ₹10,000. Without PAN, TDS is 20%. You can claim a refund of excess TDS when filing your ITR if your actual tax liability is lower. There is no provision for Form 15G/15H to avoid TDS on FRSB (unlike bank FDs).
Under 60 years: Premature redemption is NOT allowed. You must hold the bond for the full 7-year tenure. Senior citizens can exit early based on age at the time of investment: 60–70 years: exit after 6 years. 70–80 years: exit after 5 years. 80+ years: exit after 4 years. A penalty of 50% of the last coupon (half-year interest amount) is deducted on premature withdrawal. On death of the bondholder, the bond is repaid to the nominee/legal heir with interest accrued up to the date of death, without any penalty. The bond is not tradeable on any exchange, not transferable to another person (except nominee on death), and cannot be used as collateral for any loan.
FRSB (8.05%): No investment cap, no 80C, fully taxable, 7-year lock-in, floating rate. Best for large lump sums beyond PPF/SCSS limits. PPF (7.1%): ₹1.5L/year cap, EEE tax status (completely tax-free), 15-year lock-in. Best post-tax returns at higher slabs. SCSS (8.2%): Highest rate, quarterly payouts, ₹30L cap, 80C + 80TTB benefits, but restricted to 60+ citizens. Best for retirees. NSC (7.7%): 80C benefit, 5-year lock-in, interest compounded annually but paid at maturity. Years 1–4 accrued interest qualifies for 80C reinvestment deduction. For a 30% slab investor, PPF gives ~7.1% post-tax (tax-free), while FRSB gives ~5.6% post-tax. But PPF caps at ₹1.5L/year — if you have ₹50L to invest, FRSB is one of the few sovereign options with no cap.
