How a certificate grows
You buy the certificate and leave it for 5 years. Interest is added once a year and paid with the deposit at the end. Each year’s interest is rounded to the nearest rupee. The smallest amount is ₹1,000. There is no maximum on this page.
7.7% is the current National Savings Certificate rate for 1 October 2026 to 31 December 2026. The rate is on the small-savings card. A certificate uses the rate for the quarter you buy it.
A worked example: ₹1 lakh
₹1,00,000 at 7.7% grows to ₹1,44,903. Interest is ₹44,903. Year by year, the interest is ₹7,700, ₹8,293, ₹8,931, ₹9,619, ₹10,360.
In the old regime, the first four years are treated as reinvested under Section 123 (this was Section 80C). That is ₹34,543. Section 202 does not allow it, so the same certificate in the new regime still matures at ₹1,44,903 but the reinvested figure is ₹0. The shared cap is ₹1,50,000. This form does not apply it. Year 5 is taxable and is not reinvested. The section 123 guide lists what else shares the cap.
