NSC Calculator
The National Savings Certificate (NSC) is a fixed-income post office scheme with a 5-year lock-in, backed by the Government of India. You invest a lump sum, and the interest compounds every year until maturity. This NSC calculator turns your deposit, the current rate, and the 5-year term into a clear maturity figure, so you can see exactly how much you will receive and how much of that is interest. It helps you compare NSC against an FD or PPF before you commit.
Current NSC rate is 7.7% p.a., compounded annually, 5-year lock-in.

About the NSC Calculator
An NSC calculator projects the maturity value of a National Savings Certificate, where interest is compounded annually over a fixed 5-year term at the rate in force when you buy it (currently around 7.7%). Once purchased, your rate is locked for the full term regardless of later changes.
Why it is useful
NSC has a distinctive tax quirk: the interest is taxable, but because it is reinvested each year rather than paid out, that reinvested interest also qualifies for a fresh Section 80C deduction — in every year except the last, when it is paid out with maturity. A calculator shows the year-by-year build-up so you can plan both your returns and your 80C claims accurately.
How the calculation works
The maturity value uses annual compounding: M = P(1 + r)^5, where P is your investment, r is the annual interest rate as a decimal, and 5 is the fixed term in years. Each year the interest is added to the balance, so the following year earns interest on a larger base.
Key inputs explained
- Investment amount: The lump sum you deposit; there is no upper limit, and the minimum is ₹1,000.
- Interest rate: The annual rate at purchase, fixed for the full term (currently around 7.7%).
- Tenure: Fixed at 5 years for NSC; the certificate cannot be extended.
Example calculation
Inputs
- Investment (P)
- ₹1,00,000
- Interest rate (r)
- 7.7% p.a.
- Tenure
- 5 years
Calculation breakdown
- Growth factor
- (1 + 0.077)^5 ≈ 1.449
- Maturity value
- 1,00,000 × 1.449
- Interest earned
- 1,44,903 − 1,00,000
Your ₹1 lakh grows to about ₹1,44,903 in 5 years, earning roughly ₹44,903 in interest. Most of that interest qualifies for 80C in the year it accrues; only the final year's interest does not.
Benefits
- Sovereign-backed capital safety with a fixed, locked-in return.
- The deposit qualifies for Section 80C, up to the ₹1.5 lakh limit.
- Reinvested interest earns a fresh 80C deduction in the interim years.
Limitations
- The 5-year lock-in allows premature withdrawal only in limited cases, such as the holder's death or a court order.
- Interest is fully taxable at your slab rate, unlike PPF which is tax-free.
- Returns are fixed and can trail inflation or equity over long horizons.
Tips
- Claim each year's accrued interest under 80C so you are not taxed on money you never received in hand.
- Compare the NSC rate with the prevailing 5-year FD and PPF rates before deciding.
- You can pledge NSC as collateral for a loan without breaking the investment.
