Key Takeaways

NSC currently offers 7.7% interest per annum compounded annually for a 5-year tenure. This fixed return helps you calculate your exact maturity amount in advance using a national savings certificate India calculator.
The minimum investment amount is ₹1,000, and there is no maximum limit. However, only investments up to ₹1,50,000 in a financial year qualify for deduction under Section 80C of the Income Tax Act. You can verify returns easily through an NSC certificate calculator.
NSC interest is taxable on an accrual basis every year, but the interest earned in the first four years is deemed reinvested and qualifies for the Section 80C deduction. The final year’s interest is taxable and does not qualify for a deduction. Many investors confirm this using an NSC calculator SBI before filing returns.

An NSC Calculator is an online tool that helps you calculate the maturity amount and total interest earned on a National Savings Certificate investment. It uses the fixed interest rate declared by the Government of India and applies annual compounding over the 5-year tenure to show your exact returns before you invest.

You can use a national savings certificate India calculator to check your total maturity value instead of manually calculating compound interest.
