Invest ₹1,50,000 in NSC at 7.7% compounded annually. After 5 years, maturity value = ₹2,17,355, total interest = ₹67,355. Section 80C benefit: principal (₹1.5L in year 1) plus reinvested interest in years 2-4 (₹11,550 + ₹12,439 + ₹13,397 + ₹14,429 = ₹51,815 over 4 years). At 6% inflation, real return is only ~1.6% p.a. — maturity purchasing power drops to ₹1,62,376. For tax-free alternative, see PPF Calculator. For higher growth, explore Mutual Fund Calculator.
The National Savings Certificate (NSC) is a Government of India-backed fixed-income savings scheme available at all India Post offices. With a current interest rate of 7.7% compounded annually, 5-year lock-in, and Section 80C tax deduction eligibility, NSC remains one of the most popular tax-saving instruments for conservative Indian investors. This NSC Calculator India computes the exact maturity value, year-by-year compounding breakdown, Section 80C benefit schedule, and the inflation-adjusted real return.
The inflation perspective is critical for NSC investors: at 7.7% nominal return and 6% CPI inflation, the real return is approximately 1.6%. For investors in the 30% tax bracket, the post-tax real return on the 5th year interest can turn negative. This doesn't make NSC a bad investment — it serves its purpose of capital safety and tax saving — but investors should understand the purchasing power erosion. NSC falls in the debt and fixed-income category — compare with equity instruments using our Inflation Calculator and Purchasing Power Calculator to see the full impact.
Where P is the investment amount, r is the annual interest rate (7.7% = 0.077), and the tenure is fixed at 5 years. Interest is compounded annually but reinvested — no payout until maturity.

This unique double benefit (principal + reinvested interest under 80C) gives NSC an edge over tax-saving FDs where interest is fully taxable annually. The total 80C benefit across 5 years = ₹1,00,000 (principal) + ₹34,544 (interest years 1-4) = ₹1,34,544 for a ₹1 lakh investment.

NSC real returns have compressed from ~3-4% in 2016-19 to ~1.6% currently as CPI inflation has risen while rates have moderated. Track the latest CPI data on our Historical CPI Indices page and explore the relationship between government bond yields and inflation with our Inflation Formula guide.
The current NSC interest rate is 7.7% per annum for FY 2025-26. The rate is reviewed and revised quarterly by the Ministry of Finance, Government of India. Interest is compounded annually but is reinvested and paid out only at maturity after 5 years. The rate at the time of purchase is locked in for the entire 5-year tenure — even if the government revises rates later, your certificate continues earning the rate at which it was purchased. Historically, NSC rates have ranged from 6.8% to 8.5% over the past decade.
NSC maturity value is calculated using the compound interest formula: Maturity Value = Principal x (1 + Rate/100)^5. At the current rate of 7.7%, ₹1,00,000 invested in NSC matures to ₹1,44,903 after 5 years, earning ₹44,903 in total interest. The interest compounds annually — each year's interest is added to the principal for the next year's calculation. However, no interest is paid out during the 5 years; the entire amount (principal plus accumulated interest) is paid as a lumpsum at maturity. This compounding effect is what makes NSC more effective than simple interest instruments.
NSC provides a unique double tax benefit under Section 80C. First, the principal invested (up to ₹1.5 lakh per year) qualifies for Section 80C deduction. Second, the interest earned in years 1 through 4 is deemed reinvested and also qualifies for 80C deduction in each respective year. Only the 5th year interest is fully taxable as Income from Other Sources without any 80C benefit. No TDS is deducted on NSC interest or maturity. For example, on ₹1 lakh investment at 7.7%, the year 1 interest of ₹7,700 can be claimed under 80C in year 2, and so on. This makes the effective post-tax return higher than FDs for investors in higher tax brackets.
No, premature withdrawal of NSC is generally not permitted. The 5-year lock-in is strict, with only three exceptions: death of the account holder (nominee or legal heir receives principal plus accrued interest), court order for forfeiture, and pledgee forfeiture if the NSC was used as collateral. If you need liquidity, you can pledge your NSC certificate as collateral for a bank loan — banks typically lend 75-90% of the surrender value against NSC, and you continue earning interest on the certificate while using the loan amount. This is a practical alternative to premature withdrawal.
Both qualify for Section 80C, but they differ significantly. NSC has a 5-year lock-in (vs PPF's 15-year lock-in), making it better for shorter horizons. NSC currently offers 7.7% compounded annually while PPF offers 7.1% compounded annually. However, PPF interest is completely tax-free, while NSC's 5th year interest is taxable. For a 30% tax bracket investor, NSC's effective return after tax on the 5th year interest is slightly lower than PPF's tax-free return over 15 years. NSC is better for 5-year goals; PPF is better for long-term wealth building due to tax-free compounding. Use our PPF Calculator for comparison.
NSC currently offers 7.7% compounded annually, while tax-saving FDs offer 6.5-7.5% depending on the bank (senior citizens get 0.5% extra). Both have a 5-year lock-in and qualify for Section 80C. The key difference is tax treatment: FD interest is fully taxable every year (TDS deducted), while NSC interest for years 1-4 is deemed reinvested and qualifies for additional 80C deduction. This makes NSC's effective post-tax return significantly higher. For a 30% bracket investor, NSC's tax-adjusted return beats FD by approximately 0.5-1.5% annually. Use our FD Calculator to compare specific scenarios.
NSC is available to resident Indian citizens only — NRIs, HUFs, trusts, and companies cannot invest. Any individual above 10 years can open their own account. Parents or guardians can open accounts on behalf of minors. Joint accounts are allowed with up to 3 holders (Joint A: payable to all, Joint B: payable to any one). The minimum investment is ₹1,000 with additional investments in multiples of ₹100. There is no maximum investment limit, but the Section 80C deduction is capped at ₹1.5 lakh per year across all 80C instruments combined. NSC can be purchased at any India Post office or through the India Post online portal.
At the current NSC rate of 7.7% and average CPI inflation of 6%, the real return is approximately 1.6% per year (using the Fisher equation: (1+0.077)/(1+0.06) - 1). This means NSC barely beats inflation in real terms. For a 30% tax bracket investor, the post-tax return on the 5th year drops further, potentially resulting in negative real returns after tax. This is the fundamental limitation of all fixed-income instruments. While NSC provides capital safety and guaranteed returns, investors should complement it with equity investments (via SIP in mutual funds at 12%+ CAGR) for meaningful real wealth creation. Use our Inflation Calculator to see the exact purchasing power impact.
