FRSB Return Calculation Engine
The calculator performs three-layer calculations:
📐 Mathematical Formulas Used:
1️⃣ Annual Interest Calculation:
Annual Interest = Investment Amount × (Interest Rate ÷ 100)
Example: ₹5,00,000 × 8.05% = ₹40,250/year
2️⃣ Total Interest Over 7 Years:
Total Interest = Annual Interest × 7 years
Example: ₹40,250 × 7 = ₹2,81,750
3️⃣ Tax Deduction Calculation:
Tax Paid = Total Interest × (Tax Slab ÷ 100)
Example: ₹2,81,750 × 30% = ₹84,525
4️⃣ Net Post-Tax Interest:
Net Interest = Total Interest - Tax Paid
Example: ₹2,81,750 – ₹84,525 = ₹1,97,225
💡 Important Note: FRSB pays interest semi-annually (every 6 months). The calculator shows annualized figures for easier comparison. Actual payouts occur on Jan 1st and July 1st.
Multi-Scheme Comparison Engine
The calculator simultaneously compares FRSB with other government schemes:
National Savings Certificate Calculation
📊 Formula: Compound Interest (5 years)
Maturity = Principal × (1 + 7.7%)^5
NSC Interest = Maturity - Principal
NSC Net Interest = Interest - (Interest × Tax Slab)
Example: ₹5L invested → Maturity ₹7,23,392 → Interest ₹2,23,392 → After 30% tax: ₹1,56,374
Senior Citizens Savings Scheme (60+ only)
📊 Formula: Simple Interest (5 years, 8.2%)
Annual Interest = Principal × 8.2%
Total Interest = Annual Interest × 5
Taxable Interest = Max(0, Total Interest - ₹50,000)
Net Interest = Total Interest - (Taxable × Tax Slab)
Example: ₹5L → Interest ₹2,05,000 → 80TTB benefit ₹50K → Taxable ₹1,55,000 → After tax: ₹1,58,500
🏆 Automatic Winner Detection:
The calculator compares net returns and highlights the best option with:
- ✓ Thicker border (4px) on winner card
- ✓ Drop shadow effect for emphasis
- ✓ Real-time updates on input changes
Year-wise Projection Table Generator
Creates a detailed 7-year breakdown showing interest for each year:
🔄 Loop-Based Calculation Process:
For each year (1 to 7):
• Calculate annual interest
• Calculate tax on that year's interest
• Calculate net interest (after tax)
• Display in table row
• Add to running totals
The table updates in real-time whenever you adjust any input slider or dropdown.
⚠️ Assumption: The calculator assumes a constant interest rate for projection purposes. In reality, FRSB rates reset every 6 months based on NSC rates.

Example: If you invest ₹2 lakhs at 8.05%, annual interest is ₹16,100. TDS will be deducted!
How to Avoid TDS?
Form 15G/15H WON’T work: Unlike FDs, these forms don’t exempt TDS for FRSB
Only way: Get Exemption Certificate from Income Tax Department if total income is below taxable limit
Tax Filing
Interest must be declared under "Income from Other Sources" in your ITR. Taxed as per your slab rate.

5 Pro Tips for FRSB Investment
💡 Tip 1: Rate Reset Advantage
If interest rates rise, FRSB automatically adjusts upwards every 6 months – better than fixed deposits!
📊 Tip 2: For Senior Citizens
Seniors get ₹50,000 tax deduction under 80TTB. SCSS might be better if you need quarterly payouts.
⏰ Tip 3: 7-Year Lock-in
FRSB has 7-year tenure (seniors exit after 6). Invest only surplus funds you won’t need soon.
💰 Tip 4: Tax Planning
Interest is taxable but paid out (not reinvested), helping manage tax liability better than NSC.
🎯 Tip 5: Diversification Strategy
Don’t put all savings in FRSB. Mix with FDs, SCSS (if eligible), and PPF for balanced portfolio.
Example: How Priya Invested ₹5 Lakhs in FRSB
Investment Details:
- • Amount: ₹5,00,000 in FRSB (Jan 2024)
- • Tax Slab: 30%
- • Average Rate: 8.05% p.a.

Frequently Asked Questions (FAQs)
1. What are Floating Rate Savings Bonds (FRSB)?
Floating Rate Savings Bonds (FRSB) 2020 (Taxable) are debt instruments issued by the Government of India with a 7-year tenure. The interest rate is not fixed but “floats” – meaning it resets every 6 months based on the National Savings Certificate (NSC) rate plus a fixed spread of 0.35%. The rate resets on January 1st and July 1st every year. Currently, the FRSB rate is 8.05% per annum (as NSC rate is 7.70%).
2. Who is eligible to invest in FRSB?
Eligible Investors:
- Resident Indian individuals (including minors through guardian)
- Hindu Undivided Families (HUFs)
- Charitable institutions
- Universities
NOT Eligible:
- Non-Resident Indians (NRIs)
- Companies and trusts
- Foreign nationals
3. What is the minimum and maximum investment amount in FRSB?
Minimum Investment: ₹1,000
Maximum Investment: No upper limit
You can invest in multiples of ₹1,000. Unlike many other small savings schemes, FRSB does not have a maximum investment cap, making it suitable for large investments as well.
4. How is the interest paid out on FRSB?
Interest on FRSB is paid out semi-annually (every 6 months) directly to your bank account. The interest is calculated on the principal amount and credited on:
- January 1st (for the period July 1 – December 31)
- July 1st (for the period January 1 – June 30)
Note: Unlike NSC where interest is compounded, FRSB interest is paid out regularly, providing a steady income stream.
5. Can I withdraw my FRSB investment before 7 years?
For Regular Investors (Below 60 years):
❌ Premature withdrawal is NOT allowed. You must hold the investment for the full 7 years.
Exception: Only in case of death of the investor.
For Senior Citizens (60+ years):
✅ You can withdraw after completing 6 years without any penalty.
This special provision makes FRSB more flexible for senior citizens.
6. Is TDS deducted on FRSB interest?
Yes, TDS (Tax Deducted at Source) is applicable on FRSB interest if:
- Annual interest income exceeds ₹10,000 in a financial year
- TDS rate is as per your PAN card status
⚠️ Important: Unlike Fixed Deposits, Form 15G/15H will NOT work to avoid TDS on FRSB. You need to obtain an exemption certificate from the Income Tax Department if your total income is below the taxable limit.
Example: If you invest ₹2,00,000 at 8.05%, annual interest is ₹16,100. TDS will be deducted as it exceeds ₹10,000.
7. Are there any tax benefits under Section 80C for FRSB investment?
❌ No, FRSB investment does NOT qualify for Section 80C deduction.
The principal amount invested in FRSB cannot be claimed as a deduction under Section 80C of the Income Tax Act. This is one of the key differences between FRSB and other schemes like:
- NSC (National Savings Certificate) – 80C benefit available
- 5-year Tax Saver FD – 80C benefit available
- PPF – 80C benefit available
However, the interest earned is fully taxable as per your income tax slab under “Income from Other Sources”.
8. How do I buy FRSB? Where can I invest?
You can purchase FRSB through:
🏦 Scheduled Commercial Banks:
- • HDFC Bank
- • ICICI Bank
- • Axis Bank
- • SBI
- • Most other banks
✅ Required Documents:
- • PAN Card (mandatory)
- • Aadhaar/Passport
- • Bank account details
- • Application form
- • Nomination (optional)
Most banks allow online investment through their internet/mobile banking platforms. You can also visit your nearest bank branch.
9. What happens to FRSB if the interest rate falls in future?
Since FRSB has a floating interest rate, your returns will adjust based on the NSC rate:
📉 If NSC rate decreases:
Your FRSB rate will also decrease automatically after the next reset date (Jan 1 or July 1). For example, if NSC drops to 7.00%, your FRSB rate becomes 7.35%.
📈 If NSC rate increases:
Your FRSB rate will increase automatically. For example, if NSC rises to 8.00%, your FRSB rate becomes 8.35%.
This makes FRSB better than fixed-rate instruments during rising interest rate scenarios, but riskier during falling rate environments.
10. Can I take a loan against FRSB?
❌ No, loans cannot be availed against FRSB.
Unlike some other government securities like NSC or KVP (Kisan Vikas Patra), FRSB cannot be pledged as collateral for obtaining loans from banks or financial institutions.
If you need liquidity, you’ll have to wait for the maturity period (7 years for regular investors, 6 years for senior citizens) or in case of emergency, only death of the investor allows premature encashment.
11. Is FRSB better than Fixed Deposits (FD)?
Both have pros and cons. Here’s a quick comparison:
| Aspect | FRSB | Bank FD |
|---|---|---|
| Interest Rate | 8.05% (higher) | 6.5-7.5% |
| Safety | Govt backed | DICGC ₹5L |
| Liquidity | Very Low | High |
| Rate Type | Variable | Fixed |
Bottom line: Choose FRSB if you want higher returns, government safety, and don’t need liquidity. Choose FD if you might need to withdraw early.
12. Can I hold FRSB in joint names?
✅ Yes, FRSB can be held jointly.
You can invest in FRSB in joint names with the following holding patterns:
- Single Holder: One person holds the bond
- Joint Holders (either or survivor): Any holder can operate
- Joint Holders (former or survivor): First holder operates primarily
📌 Important:
- • Up to 3 joint holders are allowed
- • All joint holders must be resident Indians
- • Interest will be paid to the first holder’s bank account
- • Nomination facility is available
13. What is the difference between FRSB and NSC?
| Feature | FRSB | NSC |
|---|---|---|
| Tenure | 7 years | 5 years |
| Interest Rate | 8.05% (variable) | 7.70% (fixed) |
| Interest Payout | Semi-annual | Compounded |
| 80C Benefit | No | Yes |
| Max Investment | No limit | No limit |
| Best For | Regular income | Lump sum maturity |
💡 Pro Tip: Choose NSC if you want Section 80C benefits and don’t need regular income. Choose FRSB if you want higher returns and semi-annual income.
14. Can minors invest in FRSB?
✅ Yes, minors can invest in FRSB through a guardian.
How it works:
- The investment must be made by a natural guardian (parent) or court-appointed guardian
- The guardian operates the account on behalf of the minor
- When the minor turns 18, the account can be transferred to their name
Required Documents:
- • Minor’s birth certificate
- • Guardian’s PAN card
- • Guardian’s identity and address proof
- • Minor’s Aadhaar (if available)
Note: Interest income will be clubbed with the guardian’s income for tax purposes until the minor becomes a major.
15. What happens to FRSB in case of death of the bondholder?
In case of death of the bondholder, the FRSB can be prematurely encashed:
If Nomination is Registered:
The nominee can claim the bond amount along with accrued interest by submitting:
- • Death certificate of the bondholder
- • Claim application
- • Original bond certificate
- • Nominee’s identity proof
If No Nomination:
Legal heirs can claim through succession certificate or other legal documents as per bank’s requirement.
⚠️ Important: Always register a nominee while purchasing FRSB to make the claim process easier for your family.
16. Should I invest in FRSB or SCSS (Senior Citizens Savings Scheme)?
For senior citizens (60+ years), both are good options. Here’s how to decide:
Choose SCSS if:
- ✓ You need quarterly income
- ✓ You want 80C deduction
- ✓ You want 80TTB deduction (₹50k)
- ✓ You prefer shorter tenure (5 years)
- ✓ Max investment needed: ₹30 lakhs
Choose FRSB if:
- ✓ Semi-annual payout is okay
- ✓ You want variable rates
- ✓ No max investment limit needed
- ✓ You can hold for 7 years
- ✓ You expect interest rates to rise
💡 Pro Tip: Many seniors diversify by investing in both SCSS (for regular income) and FRSB (for higher returns on surplus funds).
