What is NSC? 

The National Savings Certificate (NSC) is a government-backed savings instrument that offers a fixed rate of return over a 5-year maturity. You can easily invest in an NSC at any post office in India. An NSC is a tax-efficient investment instrument, and investments in it are eligible for a tax deduction of up to ₹1,50,000 under Section 80C of the Income Tax Act.

Types of NSC account 

  • Single Holder Account: An adult can open this for themselves or a minor, and additionally, a minor aged 10 years or above may open a single holder account in their name.
  • Joint “A” Type Account: Can be opened by up to three adults, and when it matures, the money goes to both account holders, and they must sign together, so payments go to both of them (or, if one of them passes away, then to the survivor)
  • Joint “B” Type Account: Also for up to three adults, but in this case, and when it matures, Joint “B” lets either of them sign alone, so when they are alive, either one can receive the money, and if one dies, the survivor still gets the full amount.

How to NSC Calculator formula with an example?

The NSC calculator is based on the compound interest formula. The interest rate is fixed and compounded annually for 5 years.

The formula to calculate the final maturity value in NSC is:

nsc calculator formula

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

Where,

  • A = Final value of the maturity
  • P = Principal invested amount 
  • r = Rate of interest offered, current rate is 7.7% per annum.
  • n = number of years, i.e., the maturity period, which is 5 years.

How to Calculate NSC Maturity Amount?

So there are 2 ways to calculate the NSC maturity amount

  • With a manual calculator 
  • With Indmoney, NSC calculator 

Let’s try both ways 

Assumption 

Amount invested (P) - 5000

Interest (r) - 7.7%

Tenure (n) - 5 years 

With Manual Calculation 

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

A = 5000 × (1.077)^5 = 7245.16

With NSC Calculator

Now, if you use a calculator instead of this manual calculation, you will get these figures:

Principal Amount: ₹5,000
Total Interest: ₹2,245
Total Amount: ₹7,245

This is the same as manual calculation, but also provides information on how much interest you have generated over the 5 years.
