SSY Calculator

What Is the Sukanya Samriddhi Yojana Calculator?

Sukanya Samriddhi Yojana (SSY) is a government-backed small savings scheme for a girl child. A parent or guardian deposits a fixed amount each year for 15 years, and the account matures 21 years from opening. The SSY Calculator projects the maturity value from your yearly deposit and the current interest rate. The scheme currently pays 8.2% per annum compounded annually, a rate the government reviews every quarter, so treat it as indicative and confirm the latest figure.

How the Calculation Works

Each year the deposit is added to the running balance and interest is applied to the whole balance:

Where B_y is the balance at the end of year y, D_y is the yearly deposit for the first 15 years and zero afterwards, and r is the annual interest rate as a decimal. The loop runs for 21 years, so deposits stop after year 15 while the balance keeps compounding for the final 6 years.

Worked Example

Deposit ₹1,00,000 every year for 15 years at 8.2%, then let the balance compound until maturity at year 21:

• Total deposited: ₹1,00,000 × 15 = ₹15,00,000
• Maturity value: approximately ₹47,88,000
• Interest earned: approximately ₹32,88,000

The same deposit at ₹1,50,000 per year, the maximum allowed, would grow to roughly ₹71,82,000 by maturity. Small rate changes over 21 years make a meaningful difference, which is why running the numbers before committing helps.
