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 annual compounding as notified by the Ministry of Finance: M = P × (1 + r)^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 — 7.7% per annum applied to purchases made in the April–June 2026 quarter; check the current quarterly notification before buying. 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 7.7% (compounded annually) matures to approximately Rs 1,44,903 after 5 years. The breakdown: Year 1 interest Rs 7,700 (deemed reinvested, eligible for 80C); Year 2 ≈ Rs 8,293 (reinvested, 80C eligible); Year 3 ≈ Rs 8,931 (reinvested, 80C eligible); Year 4 ≈ Rs 9,619 (reinvested, 80C eligible); Year 5 ≈ Rs 10,360 (paid at maturity, taxable). Total interest ≈ Rs 44,903. 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 (as notified for April–June 2026; reset quarterly), 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).

NSC at the Post Office in 2026 — Rates, Process, What You Need

The National Savings Certificate pays 7.7% p.a. for the April–June 2026 quarter (the April–June 2026 quarter — rates are reset quarterly, so check the current notification before investing), compounded annually and paid at maturity after 5 years. Two features matter most. The rate is locked at purchase: whatever the Ministry of Finance notifies for the quarter you buy in applies for your full 5 years, even if subsequent quarterly resets change the rate for new buyers. And the entry bar is low: minimum Rs 1,000, in multiples of Rs 100, with no upper limit — though only Rs 1.5 lakh a year earns the Section 80C deduction. Buying is a same-day process at any of India's roughly 1.6 lakh post offices: carry PAN and Aadhaar (plus address proof if your Aadhaar address differs), fill Form-1, and pay by cash, cheque or a debit from your Post Office Savings Account (POSA). Pre-printed paper certificates were discontinued back in July 2016; NSC is now issued as a passbook entry or in e-mode through a Post Office Savings Account — choose e-mode if you hold a POSA with DOP net or mobile banking (the certificate reflects instantly and is manageable online), or passbook mode otherwise. Certificates can be pledged as collateral for bank loans and transferred once to another person. Premature closure is allowed only on death, court order or forfeiture by a pledgee — treat the 5-year lock-in as real.

NSC for Exactly 5 Years — Year-by-Year Accrual on Rs 1 Lakh

NSC interest compounds annually, so a Rs 1,00,000 certificate bought at 7.7% accrues like this: Year 1 interest Rs 7,700 (balance Rs 1,07,700); Year 2 Rs 8,293 (Rs 1,15,993); Year 3 Rs 8,931 (Rs 1,24,924); Year 4 Rs 9,619 (Rs 1,34,543); Year 5 Rs 10,360, giving a maturity value of approximately Rs 1,44,903. The rate is locked on the day you buy — later quarterly resets do not touch an existing certificate. The tax treatment tracks the accrual: interest for years 1 through 4 is deemed reinvested and qualifies for a fresh Section 80C deduction in each of those years (within the Rs 1.5 lakh ceiling), while the final year's Rs 10,360 is paid out rather than reinvested and is taxable as Income from Other Sources at your slab rate. Since no TDS is deducted on NSC, you must self-report it — declaring the accrued interest annually rather than as a lump sum at maturity usually spreads the tax more efficiently.
