This NSC calculator works out the maturity value of a National Savings Certificate, the 5-year post office savings bond. Enter the amount you invest; at the current rate of 7.7% compounded yearly, it shows the maturity value, the total interest and the interest that accrues each year, which matters if you claim it as a deduction under the old tax regime.
What is a NSC Calculator?
The National Savings Certificate (NSC) VIII Issue is a fixed-income savings bond sold at post offices. You invest a lump sum, it earns a fixed rate compounded every year, and you receive the whole amount with interest after 5 years. The rate that applies on the day you buy stays the same for the full term.
NSC is popular with conservative savers and with people using the old tax regime, because both the investment and the interest for the first four years count towards the deduction limit familiar as Section 80C. An NSC calculator shows the maturity value and the year-wise interest you need for your tax return.
How does the NSC Calculator work?
NSC interest compounds once a year but is paid only at maturity. The calculator multiplies the investment by (1 + rate) five times, and records the interest added in each year.
For the first four years, that interest is deemed to be reinvested in NSC, so under the old regime it can be claimed as a fresh deduction. In the fifth year it is simply taxable.
