How does NSC compound?

Annually, and the interest is paid at the 5-year maturity (NSC VIII Issue). This page does not split the deemed-interest 80C add-back in years 1–4.

Why is the rate an input?

Small-savings rates are notified every quarter. A hardcoded 7.7% would rot.

NSC itself has no PPF-style ₹1.5 lakh purchase cap. Section 80C still does, on the old regime.

PPF locks 15 years and compounds in a running account. NSC is a 5-year certificate. Use both pages if you are splitting 80C.
