What is an NSC Calculator?
The National Savings Certificate is a fixed-tenure, government-backed instrument available through India Post, with a 5-year lock-in and interest compounded annually but paid out only at maturity along with the principal. For taxpayers using the old regime, it can also count toward the aggregate ₹1.5 lakh savings deduction commonly known as Section 80C; that deduction is not available under the new regime. It suits conservative savers who want a government-backed return rather than market-linked instruments.
Under the old regime, interest for the first four years is treated as reinvested and can count toward the aggregate savings-deduction limit each year, subject to eligibility and the overall ₹1.5 lakh cap. The final year’s interest is taxable as income in the year of maturity.
How the maturity value is calculated
Standard annual compounding over the fixed 5-year term — there’s no partial withdrawal option, so the full compounding period always applies.
Worked example, and how it compares to an equivalent FD
Invest ₹1,00,000 in an NSC at the current 7.7% rate, and it matures to roughly ₹1,44,903 after 5 years — about ₹44,903 in interest, paid out entirely at maturity along with the principal. A 5-year bank FD offering the identical 7.7% rate, compounded quarterly, would reach roughly ₹1,46,425 — marginally higher purely because quarterly compounding edges out NSC’s annual compounding for the same headline rate. The gap is small; the more relevant real-world difference is usually the interest rate a specific FD offers versus the NSC’s government-fixed rate, not the compounding frequency.
The reinvested-interest tax deduction quirk
NSC interest for years 1 through 4 is treated as automatically reinvested back into the certificate (even though you don’t receive it in cash), which, under the old regime and subject to the aggregate limit, can count toward the savings deduction commonly known as Section 80C in those years. The final year’s interest, however, is paid out at maturity and is taxable as regular income with no further reinvestment deduction, since there’s no year 6 to reinvest into.
Frequently asked questions
What is the current NSC interest rate?
The rate is notified at 7.7% per annum for Q2 FY 2026-27 (July–September 2026), compounded annually and fixed for the certificate’s full 5-year term at whatever rate applied on the date of purchase.
Is NSC interest taxable?
Yes — unlike PPF, NSC is not fully tax-exempt. Under the old regime, interest for years 1–4 is deemed reinvested and can count toward the aggregate savings-deduction limit, while the final year’s interest is taxable as "income from other sources" in your hands.
Can I withdraw an NSC early?
Premature withdrawal is only allowed in specific cases — the holder’s death, forfeiture by a pledgee, or a court order — not on demand, which is worth knowing before locking in funds you might need.
Can NSC be used as loan collateral?
Yes — banks and NBFCs commonly accept NSC certificates as collateral (pledged security) for a loan, since they’re government-backed and easy to value.
Is there a maximum investment limit for NSC?
No upper limit, unlike SCSS or SSY — you can invest any amount, though under the old regime only up to the aggregate ₹1.5 lakh savings-deduction limit can count for tax deduction; that deduction is unavailable under the new regime.
Can I buy NSC online?
NSC is available through India Post and select authorised bank branches; availability of a fully online purchase process varies by provider, so check with your bank or the nearest post office for the current process.
NSC or a tax-saving (ELSS) mutual fund — how do they compare?
NSC offers a fixed, government-guaranteed return with no market risk. ELSS is market-linked with historically higher but unguaranteed returns and a shorter 3-year lock-in versus NSC’s 5 years. The choice comes down to risk appetite and lock-in preference, not one being objectively better.
