How the NSC Calculator Works
The National Savings Certificate (NSC) is a fixed-income post-office scheme with a 5-year term and annual compounding. You invest a lump sum, the interest compounds each year, and the whole amount is paid out at maturity. This calculator turns your investment and the interest rate into the maturity value and total interest earned.
The Formula
NSC compounds annually, so the maturity value is a straightforward compound-interest calculation:
Maturity = P × (1 + r)^5
Where P is the amount invested and r is the annual interest rate as a decimal (for 7.7%, r = 0.077). The exponent is fixed at 5 because the NSC term is always 5 years.
Worked Example
Investing INR 1,00,000 at a rate of 7.7%:
- Maturity = 100000 × (1.077)^5
- (1.077)^5 = 1.44903
- Maturity = 100000 × 1.44903 = INR 1,44,903
- Interest earned = 144903 − 100000 = INR 44,903
Maturity at Different Investment Amounts
Because NSC compounds at a fixed rate for 5 years, the maturity scales directly with how much you invest:
| Investment | Rate | Maturity (5 yrs) | Interest |
|---|---|---|---|
| INR 50,000 | 7.7% | ≈ INR 72,452 | ≈ INR 22,452 |
| INR 1,00,000 | 7.7% | ≈ INR 1,44,903 | ≈ INR 44,903 |
| INR 5,00,000 | 7.7% | ≈ INR 7,24,517 | ≈ INR 2,24,517 |
Why Choose NSC
NSC is backed by the Government of India, so the return is guaranteed and the rate is locked for the full 5 years from your date of purchase, shielding you from later rate cuts. It also offers a Section 80C deduction, making it popular for tax planning. There is no maximum investment limit, although only INR 1.5 lakh per year qualifies for the 80C deduction.
Frequently asked questions
How is the NSC maturity amount calculated?+
The National Savings Certificate uses annual compounding over a fixed 5-year term. Maturity equals your investment multiplied by (1 + rate) raised to the power 5. Interest is added to the principal each year but paid out only at maturity.
What is the current NSC interest rate?+
NSC pays a government-set rate that is reviewed each quarter and locked in for the full 5 years from the date you invest. It was 7.7% per year at the time of writing. Because the rate can change, the calculator lets you enter the applicable rate.
Is NSC interest compounded annually or paid out yearly?+
NSC interest is compounded annually, meaning each year's interest is added to the principal so the next year earns interest on a larger base. However, the interest is reinvested and paid out only when the certificate matures after 5 years.
How much will INR 1,00,000 grow to in NSC?+
At a 7.7% annual rate, INR 1,00,000 grows to about INR 1,44,903 after 5 years, an interest gain of roughly INR 44,903. Enter your own amount and rate in the calculator for an exact figure.
Does NSC give a tax benefit?+
The amount you invest in NSC qualifies for a deduction under Section 80C, up to the overall 80C limit. The yearly accrued interest is also treated as reinvested and is eligible for 80C in the years it accrues, except in the final year.
