PPF Maturity Calculation Year by Year
A year-by-year table shows how annual deposits and credited interest combine. Actual PPF rates may change, so this is an educational illustration.
Illustration assumptions
- ₹1.5 lakh is deposited before 5 April each year.
- A constant 7.1% annual rate is used for all 15 years.
- No withdrawals or loans are modeled.
- Interest is shown rounded to the nearest rupee.
Year-by-year PPF illustration
| Year | Total deposited | Estimated closing balance |
|---|---|---|
| 1 | ₹1.50 lakh | ₹1.61 lakh |
| 3 | ₹4.50 lakh | ₹5.17 lakh |
| 5 | ₹7.50 lakh | ₹9.22 lakh |
| 7 | ₹10.50 lakh | ₹13.87 lakh |
| 10 | ₹15.00 lakh | ₹22.17 lakh |
| 12 | ₹18.00 lakh | ₹28.76 lakh |
| 15 | ₹22.50 lakh | ₹40.68 lakh |
Why later interest becomes larger
Interest is earned on both deposits and previously credited interest. As the balance grows, the same percentage produces a larger rupee amount. This is compounding, but its effect depends on the actual rates notified in each period.
Contribution timing
The calculator models a full-year contribution by placing it before 5 April. Depositing later can change the eligible balance used for monthly interest calculations under PPF rules. Verify operational cut-off dates with the account provider.
What this table cannot predict
The PPF rate is not locked for the entire account term. Rules, tax treatment and extension procedures may also change. Use the table to understand mechanics, then check current official information before acting.
