NSC (National Savings Certificate) Calculator
Calculate the maturity value of a National Savings Certificate. NSC has a 5-year lock-in and interest compounds annually.
Current NSC rate is 7.7% p.a., compounded annually and paid at maturity (5 years).
What Is an NSC Calculator?
The National Savings Certificate (NSC) is a fixed-income, Government of India small-savings scheme sold through post offices across the country. It is a popular choice among conservative Indian investors who want guaranteed returns along with a tax benefit under Section 80C.
An NSC Calculator helps you find out exactly how much your one-time investment will grow to at the end of the 5-year lock-in period. The current interest rate is 7.7% per annum, compounded annually but paid only at maturity. Because the interest accrues and is reinvested each year, NSC rewards patient investors with predictable, government-backed growth.
NSC Maturity Formula and How It Works
NSC is a lump-sum investment. You invest a single amount once, and it grows through annual compounding for five years. The maturity value is calculated with the standard compound interest formula:
FV = P × (1 + r)n
Where:
- FV = maturity value
- P = amount invested
- r = annual interest rate as a decimal (0.077)
- n = number of years (5)
A few important points about how NSC works:
- Interest is compounded annually but is paid out only at maturity, along with the principal.
- There is no maximum investment limit, though only up to ₹1.5 lakh qualifies for the Section 80C deduction.
- The minimum investment is ₹1,000, and you can buy NSC in multiples of ₹100.
Worked Example
Suppose you invest ₹1,00,000 in NSC at the current rate of 7.7% per annum for the full 5-year term.
Applying the formula: FV = 1,00,000 × (1 + 0.077)5.
This works out to a maturity value of approximately ₹1,44,900. In other words, your ₹1 lakh investment earns around ₹44,900 in interest over five years, with the entire amount backed by the Government of India.
Our NSC Calculator does this instantly. Just enter the amount you plan to invest and the prevailing interest rate, and it shows you the maturity value and the total interest you will earn.
Tax Benefits of NSC
NSC offers a useful combination of safety and tax savings:
- Section 80C deduction: Investments of up to ₹1.5 lakh in a financial year qualify for deduction from your taxable income.
- Reinvested interest: The interest earned in the first four years is deemed to be reinvested, so it also qualifies for the 80C deduction in those years. Only the final year interest is fully taxable.
- No TDS: NSC does not deduct tax at source, though the interest is taxable as per your income slab.
- Guaranteed returns: The rate is fixed at the time of purchase for the entire 5-year term, regardless of later rate changes.
Always confirm the latest notified rate on the official India Post website, since the rate is reviewed each quarter.
