NSC Calculator 2026: Calculate Your National Savings Certificate Returns
An NSC calculator 2026 helps you find the maturity value and interest on a National Savings Certificate before you invest. You enter your amount and it applies the current 7.7% rate for you.
This guide explains how the NSC calculator works, the 2026 interest rate, a year-by-year growth example, the Section 80C benefit, and how NSC compares with PPF and Post Office TD.
What Is an NSC Calculator?
The National Savings Certificate (NSC) is a government-backed, fixed-return savings scheme sold at post offices. It has a fixed 5-year term and a rate set every quarter by the government.
An NSC calculator is a simple tool that applies the compounding formula for you. It instantly shows your maturity value, total interest, and how your money grows each year.

NSC Interest Rate 2026 (7.7% p.a.)
For 2026, NSC pays 7.7% per year. The rate has stayed unchanged for several quarters, and it is the same for all investors, with no senior-citizen bonus.
Among small-savings schemes, NSC sits near the top for its short 5-year lock-in, as the chart below shows.
| Scheme | Rate (p.a.) | Tenure | Section 80C |
| NSC | 7.70% | 5 years | Yes |
| PPF | 7.10% | 15 years | Yes |
| Post Office TD (5-yr) | 7.50% | 5 years | Yes |
| KVP | 7.50% | 115 months | No |
| POMIS | 7.40% | 5 years | No |
| SCSS | 8.20% | 5 years | Yes |
Rates are reviewed every quarter by the Ministry of Finance. See the official scheme details on the India Post savings page.
How Is NSC Interest Calculated?
NSC interest is compounded annually and paid in full at maturity. The formula is: Maturity value = P × (1 + r/100)^5, where P is your deposit and r is the annual rate.
Unlike a Post Office TD, nothing is paid out yearly. Instead, the interest of each year is added to the certificate and earns interest the next year, so it fully compounds.
The accrued interest of years 1 to 4 is treated as reinvested, which is why it also qualifies for Section 80C in those years.
NSC Returns Example — Year-by-Year Growth
Take a ₹1,00,000 NSC at 7.7%. It grows to about ₹1,44,903 in five years, earning ₹44,903 in interest — a 44.9% total return.
The table below shows how the value builds each year as interest is reinvested.
| Year | Opening value | Interest @7.7% | Year-end value |
| Year 1 | ₹1,00,000 | ₹7,700 | ₹1,07,700 |
| Year 2 | ₹1,07,700 | ₹8,293 | ₹1,15,993 |
| Year 3 | ₹1,15,993 | ₹8,931 | ₹1,24,924 |
| Year 4 | ₹1,24,924 | ₹9,619 | ₹1,34,544 |
| Year 5 | ₹1,34,544 | ₹10,360 | ₹1,44,903 |
NSC Tax Benefits (Section 80C)
The NSC deposit qualifies for a deduction of up to ₹1.5 lakh under Section 80C in the year of purchase, and only under the old tax regime.
The interest is taxable, but there is no TDS. Since the interest of years 1 to 4 is reinvested, you can claim it under 80C in those years, which lowers the effective tax.
NSC vs PPF vs Post Office TD
All three are safe, government-backed options, but they differ on rate, lock-in, and how interest is paid. The table below compares them.
| Feature | NSC | PPF | Post Office TD (5-yr) |
| Rate (2026) | 7.70% | 7.10% | 7.50% |
| Term / lock-in | 5 years | 15 years | 5 years |
| Interest paid | At maturity | At maturity | Annually |
| Section 80C | Yes | Yes | Yes |
| Interest taxable | Yes (no TDS) | Tax-free | Yes (no TDS) |
