The mathematical formula behind ssy
The SSY calculation uses the compound interest formula, applied on an annual compounding basis. Interest is calculated on the lowest balance between the fifth day and the end of each month, but is credited at the end of each financial year:
Here is a breakdown of the variables involved in this formula to show you how the math works:
| Variable | Meaning | Details |
|---|---|---|
| A | Maturity value | The final tax-free amount available at the end of 21 years. |
| P | Annual Deposit | The principal amount deposited each year, capped at Rs. 1.5 lakh. |
| r | Interest Rate | The annual interest rate set by the government (currently 8.2%). |
| n | Number of Years | The compounding duration, which spans 21 years. |
Factors that impact your ssy growth
Since the Government of India reviews and updates the interest rate quarterly, fluctuations in the rate can change your actual final maturity corpus. Below is a comparison showing the projected returns on a yearly investment of Rs. 1.5 lakh across different interest rates:
| Interest rate (p.A.) | Total invested | Maturity value | Interest earned |
|---|---|---|---|
| 7.5% p.a. | Rs. 22,50,000 | Rs. 63,65,155 | Rs. 41,15,155 |
| 8.2% p.a. (Current) | Rs. 22,50,000 | Rs. 69,80,061 | Rs. 47,30,061 |
| 9.0% p.a. | Rs. 22,50,000 | Rs. 77,59,343 | Rs. 55,09,343 |

Worked example: Sukanya Samriddhi Yojana Savings strategy
Let's look at how consistent deposits grow under the Sukanya Samriddhi Yojana scheme. Below is a comparison of three different yearly deposit levels under the current interest rate of 8.2% per annum over the full 21-year maturity cycle:
| Yearly deposit | Total invested (15 yrs) | Interest earned (21 yrs) | Maturity value (age 21) |
|---|---|---|---|
| Rs. 50,000 | Rs. 7,50,000 | Rs. 15,76,687 | Rs. 23,26,687 |
| Rs. 1,00,000 | Rs. 15,00,000 | Rs. 31,53,374 | Rs. 46,53,374 |
| Rs. 1,50,000 | Rs. 22,50,000 | Rs. 47,30,061 | Rs. 69,80,061 |
By scaling the investment from Rs. 50,000 to Rs. 1.5 lakh annually, the ultimate maturity value expands by over Rs. 46 lakh. The compounding power is especially prominent in the final six years, when the account earns interest on the entire accumulated balance without requiring any further out-of-pocket contributions.
Important note
This calculator assumes the current SSY interest rate of 8.2% remains constant throughout the 21-year tenure for estimation purposes. In reality, the Government of India reviews and updates this rate quarterly.
