NSC Calculator — Calculate Returns on 5-Year NSC Investment — India 2026

Fixed Deposit Calculator

How This NSC Calculator Works

National Savings Certificate (NSC) is a Government of India small savings instrument with a 5-year lock-in. Our NSC calculator computes the maturity value using the half-yearly compounding formula notified by the Ministry of Finance: M = P × (1 + r/2)^(2 × n), where P is the deposit, r is the annual interest rate (as a decimal), and n is the term in years (5). Enter your deposit amount and the calculator returns the maturity value, total interest earned, and the year-by-year accrued interest schedule. The interest rate is reset every quarter by the Ministry of Finance — for Q1 FY 2026–27 (April–June 2026) the NSC rate is 7.7% per annum compounded half-yearly. Once you buy an NSC, the rate is locked for the full 5-year term regardless of subsequent quarterly resets.

NSC Tax Benefits Under Section 80C and Section 10

NSC offers a unique double tax benefit. (1) The amount invested qualifies for deduction under Section 80C up to the overall ceiling of Rs 1.5 lakh per financial year, alongside EPF, PPF, ELSS, and life insurance premiums. (2) The interest accrued each year for the first four years is deemed reinvested in the scheme and therefore also qualifies for Section 80C deduction in those years — most other 80C investments do not give this rolling benefit. The interest accrued in the fifth and final year is fully taxable as "Income from Other Sources" at your slab rate because it is paid out at maturity, not reinvested. There is no TDS on NSC interest (unlike bank FDs above Rs 40,000), but you must still declare it in your ITR.

NSC Maturity Value Example — Rs 1 Lakh at 7.7%

A Rs 1,00,000 investment in NSC at the current 7.7% half-yearly compounded rate matures to approximately Rs 1,45,030 after 5 years. The breakdown: Year 1 interest ≈ Rs 7,847 (deemed reinvested, eligible for 80C); Year 2 ≈ Rs 8,463 (reinvested, 80C eligible); Year 3 ≈ Rs 9,127 (reinvested, 80C eligible); Year 4 ≈ Rs 9,843 (reinvested, 80C eligible); Year 5 ≈ Rs 9,750 (paid at maturity, taxable). Total interest ≈ Rs 45,030. Effective post-tax return for a 30% slab investor: roughly 6.4% per annum — competitive with tax-saver bank FDs, better than PPF (7.1%) on shorter horizons, and lower than ELSS but with zero market risk and a sovereign guarantee.

NSC vs PPF vs Tax-Saver FD — Which Is Better

NSC, PPF, and 5-year tax-saver FDs are the three most popular Section 80C debt options. PPF: 7.1% rate (Q1 FY 2026–27), 15-year lock-in, EEE tax status (deposit, interest, and maturity all tax-free), Rs 1.5 lakh annual cap. NSC: 7.7% rate, 5-year lock-in, interest taxable in year 5, no ceiling on investment but only Rs 1.5 lakh qualifies for 80C, sovereign guarantee. 5-year tax-saver FD: 6.5–7.5% rate at most banks, taxable interest annually with TDS, Rs 1.5 lakh 80C deduction, deposit-insurance up to Rs 5 lakh per bank. Decision rule: if you have a 15+ year horizon and want fully tax-free maturity, choose PPF. If you want a higher rate with a 5-year horizon, NSC wins. If you want senior-citizen-rate access or short flexibility, FDs are simpler. Most investors should hold all three in a layered ladder.

How to Buy NSC — Post Office and Internet Banking

NSC certificates are issued only by India Post (no banks, no online aggregators). Three purchase channels: (1) walk in to any post office with PAN, Aadhaar, KYC documents, and a cheque or cash; you receive a printed Statement of Account if NSC is held in your Post Office Savings Account, or a physical certificate for older issues. (2) DOP Internet Banking — once you have a Post Office Savings Account linked to internet banking, you can buy NSC online and the holding appears in your DOP iBanking ledger. (3) IPPB (India Post Payments Bank) mobile app — increasingly the easiest path for new investors. Joint holdings are allowed (up to 3 adults), as are NSC-for-minor purchases by a guardian. Premature withdrawal is allowed only on death of the holder, court order, or after 5 years (i.e., not at all in practice unless those conditions are met).
