In-Depth Guide

Sukanya Samriddhi Yojana (SSY) compounds interest annually on deposits made for up to 15 years. The account matures after 21 years from account opening, accumulating tax-free returns under Section 80C.

How to Calculate: Step-by-Step

1. Determine annual deposit amount (minimum ₹250, maximum ₹1.5 Lakh per financial year). 2. Calculate compounded interest for 15 annual deposit cycles. 3. Allow accumulated corpus to earn compound interest without additional deposits for remaining 6 years until 21-year maturity. 4. Output total maturity corpus.

Worked Calculation Example

Deposit ₹1,50,000 annually for 15 years at 8.2% interest rate: - Total Deposited Capital = ₹22,50,000. - Total Interest Earned ≈ ₹46,80,000. - Final Maturity Amount at 21 years ≈ ₹69,30,000.
