What is an NSC calculator?

An NSC Calculator is a financial tool that computes the maturity value of an NSC investment and the amount of interest earned during its tenure. It determines how much income an individual will earn from investing in the government scheme, enabling them to evaluate their returns and plan their finances in advance.

How does an NSC calculator work?

Using a mathematical formula, an NSC calculator figures out the return on investment on the basis of variables set by an individual. Under it, the interest income is compounded every year until the 5-year lock-in period ends at a fixed interest rate of 7.70%. To know how a National Savings Certificate calculator works, you first need to understand its formula, which is also applicable to manual calculations.

Formula to Calculate NSC Interest Rate

Given below is the formula you can use to calculate your returns on NSC investment.

A = P(1 + r/100)^n

In this formula, A = Final maturity value of your investment, P = Principal amount you will invest, r = Rate of interest applicable to your investment and n = number of years or the maturity period.

Let’s understand this formula with the help of an example.

For instance, you want to invest an amount of ₹5,00,000 in an NSC investment plan offering an annual interest rate of 7.70% for 5 years.

If we put these values into the formula, we will get the Principal amount = ₹5,00,000, r = 7.70% and n = 5 years.

A = ₹ [5,00,000 (1+ 7.70/100) ^ 5] = ₹7,24,517.

Therefore, the maturity value of your investment will stand at ₹7,24,517 after a maturity period of 5 years.

Once you get the maturity amount, you can easily calculate the amount of interest earned.

As such, Interest = Maturity Amount - Principal Amount = ₹(7,24,517 - 5,00,000) = ₹2,24,517. This is how an NSC interest calculator determines the interest income.

How to Use the NSC Calculator?

Here are the steps you can follow to use the NSC calculator:

  • Step 1: Enter the amount of money you want to invest. You can use the slide bar to set your preferred amount.

  • Step 2: Enter the prevailing rate of interest in the calculator. You can also use the slide bar.

  • Step 3: The time period is predetermined and fixed at 5 years. If your calculator does not have a fixed time period, you must specify how long you want to invest.

  • Step 4: Choose a type of compound frequency from the drop-box menu, consisting of mainly two options: yearly and half-yearly.

The NSC calculator will automatically display results for you, determining the amount of interest and total maturity value of your investment.
