> The Sukanya Samriddhi Yojana calculator works out the maturity value of an SSY account for a girl child – yearly deposits for 15 years, interest at 8.2% p.a. compounded yearly, and maturity 21 years after opening.

## Inputs

- Girl's age
- Yearly investment
- Interest rate (%)
- Start year

## Results

- Total investment (15 years)
- Maturity value
- Total interest
- Maturity year
- Girl's age at maturity

## Formula

```
Value after 15 years of deposits = deposit × ((1 + r)^15 − 1) ÷ r × (1 + r)
Maturity at 21 years = value at 15 × (1 + r)^6
Deposits: ₹250 to ₹1.5 lakh a year
```

## Explanation

SSY offers one of the highest rates among small savings schemes and is fully tax-free (EEE) under the old regime. Accounts can be opened until the girl turns 10; partial withdrawal is allowed at 18 for education.

### How to use the Sukanya Samriddhi Yojana Calculator

- **Girl's age**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the girl's age, the yearly deposit, the interest rate and the year you start.

### Tips

- Figures use the latest published rates; government scheme rates are revised every quarter.
- Choose between the old and new tax regimes carefully – deductions only count in the old regime.
- Keep proofs of investments and rent for your employer and the tax return.
- Use the official portal of each scheme for exact maturity values.

### Common mistakes to avoid

- Assuming scheme interest rates are fixed for the whole term.
- Forgetting tax on interest from fixed and recurring deposits.
- Missing the yearly minimum deposit on PPF or Sukanya Samriddhi accounts.

### What each result means

- **Total investment (15 years)** = min([Yearly investment], 150000)×15
- **Maturity value** = fvc([Interest rate]÷100, 15, 0, min([Yearly investment], 150000), 1)×(1 + [Interest rate]÷100)^6
- **Total interest** = [Maturity value] - [Total investment (15 years)]
- **Maturity year** = [Start year] + 21
- **Girl's age at maturity** = [Girl's age] + 21

### Example values
