PPF Calculator
The PPF Calculator projects the maturity value of a Public Provident Fund account when you contribute each year and interest compounds annually. Enter your yearly contribution, the interest rate and the number of years to see the total invested, the interest earned and the final maturity amount.
What a PPF is
The Public Provident Fund is a long-term, government-backed savings scheme with a fixed tenure and annual compounding. You contribute each year, the balance earns interest that is added once a year, and the whole amount matures after the full term. It is popular for its safety and tax treatment.
How the growth is calculated
Each year's closing balance is the opening balance plus that year's contribution, all multiplied by (1 + rate). Because contributions keep coming in and interest compounds on the growing balance, the maturity value is much larger than the sum of contributions. The interest earned is the maturity value minus everything you put in.
A worked example
Contribute 1,50,000 a year for 15 years at 7.1%. You invest 22,50,000 of your own money over the term, and with annual compounding the account matures at roughly 40,68,000, meaning about 18,18,000 is interest. The final years contribute the most growth because they compound on the largest balance.
Getting the most from a PPF
Contributing early in the financial year gives that year's deposit more time to earn interest. Staying invested for the full term, and extending it where the scheme allows, lets compounding do its heaviest lifting in the later years. Always use the current official interest rate, as it is reviewed periodically.
