NSC Calculator

Project your National Savings Certificate maturity — 7.7% compounded yearly for a fixed 5 years, with all interest paid together at maturity.

Year-wise NSC balance
Year Invested Balance at year end
1 ₹1,00,000 ₹1,07,700
2 ₹1,00,000 ₹1,15,993
3 ₹1,00,000 ₹1,24,924
4 ₹1,00,000 ₹1,34,544
5 ₹1,00,000 ₹1,44,903

What is the National Savings Certificate?

The National Savings Certificate (NSC) is a 5-year post-office savings bond that locks your rate on the day you buy it — currently 7.7% per annum, compounded annually, with the entire interest paid together with the principal at maturity. There is no market risk and no rate risk after purchase: whatever the government notifies for later quarters, your certificate keeps its issue rate for the full five years.

Enter the investment and this calculator shows the total interest, the maturity value and the certificate\'s growth at the end of each of the five years.

The NSC maturity formula

M = P × (1.077)⁵

  • M — the maturity value after the fixed 5-year term
  • P — the amount invested (minimum ₹1,000; no upper limit)
  • 1.077 — one plus the current 7.7% annual rate

Interest compounds annually but is paid only at maturity — nothing lands in your bank account in between.

How to use this calculator

  1. Enter the investment amount — the widget accepts ₹1,000 to ₹1,00,00,000 in ₹1,000 steps.
  2. Read the total interest and the maturity value.
  3. Open the year-wise balance to see the certificate\'s value at the end of each of the five years.

A worked example

₹1,00,000 invested at 7.7%:

  • Year 1: ₹1,07,700 · Year 2: ₹1,15,993 · Year 3: ₹1,24,924 · Year 4: ₹1,34,544
  • Maturity (year 5): ₹1,44,903 — total interest ₹44,903

₹2,50,000 matures to ₹3,62,258 on the same convention — the maturity value scales in exact proportion to the amount invested.

Investment vs maturity at 7.7%

Investment Interest earned Maturity after 5 years
₹50,000 ₹22,452 ₹72,452
₹1,00,000 ₹44,903 ₹1,44,903
₹2,50,000 ₹1,12,258 ₹3,62,258
₹5,00,000 ₹2,24,517 ₹7,24,517

Rounded to the nearest rupee. The 7.7% rate applies to certificates bought in the current quarter and is revisable for future issues; certificates already purchased keep their rate.
