PPF Calculator - Public Provident Fund
Calculate PPF maturity amount, year-wise growth, and total interest earned over 15 years with current PPF interest rate.
About this calculator
The PPF Calculator projects the maturity value of a Public Provident Fund account from a yearly deposit, the interest rate and the tenure. It reports the total you invested, the interest you earn and the maturity amount, with a year-wise growth table.
PPF is tax-free on interest and maturity and is backed by the government, so it is a core holding for conservative long-term savers. Tenure can be 15 years or longer, as extensions are allowed in blocks of five years.
How to use it
- Enter your Yearly Investment, between ₹500 and ₹1,50,000.
- Check the PPF Interest Rate, currently 7.1%.
- Enter the Tenure, from 15 to 50 years.
- Press Calculate PPF and read the maturity amount and the table.
Calculation
Each year the balance becomes (Previous balance + Deposit) × (1 + rate), which assumes the deposit is made at the start of the year (April). Interest is credited annually and compounds.
Worked example
₹1,50,000 a year at 7.1% for 15 years
| Total invested | ₹22,50,000 |
| Interest earned | ₹18,18,209 |
| Maturity amount | ₹40,68,209 |
Continuing the same deposits for 25 years at 7.1% would grow the balance to about ₹1.0 crore.
Tips and common mistakes
- Open the account early. The 15-year clock starts from the end of the year you open it.
- Invest by the 5th of each month if you deposit monthly.
- Extend in blocks of five years with contributions to keep compounding tax-free.
- The rate changes quarterly, so treat the projection as indicative.
- You can hold only one PPF account in your own name.
