Estimate a Public Provident Fund maturity scenario from your current balance, annual contribution, remaining duration, and assumed annual interest rate. The rate is editable because the government notifies small-savings rates periodically.
What this PPF calculator shows
- Estimated maturity value.
- Total future deposits entered.
- Estimated interest from the current balance and future deposits.
PPF calculation method
The calculator compounds the current balance annually and assumes each annual contribution is deposited at the beginning of the year:
PPF projection formula
Next balance = (opening balance + annual deposit) x (1 + annual rate)
This repeats for the selected number of remaining years. An early contribution assumption generally produces more interest than depositing near the end of a financial year.
A new PPF account normally uses a 15-year term. The calculator also accepts a current balance and a shorter remaining period for an account already in progress, or a longer illustration for extended blocks.
Important PPF rules and limitations
The annual contribution field is constrained to Rs. 500 through Rs. 1.5 lakh, reflecting the current statutory deposit range. Verify the current limit, notified rate, extension rules, loan and withdrawal eligibility, and account status before acting.
Check the official National Savings Institute PPF page and small-savings interest-rate table for current scheme terms and rates.
Actual PPF interest is calculated under scheme rules using qualifying monthly balances and is credited annually. This yearly model does not reproduce the exact day and month of every deposit. It also assumes one unchanged rate throughout the projection, while notified rates can move during the term.
Common questions
Is the PPF interest rate fixed for 15 years?
No. The government notifies the rate periodically. Use multiple rate scenarios instead of treating today’s rate as guaranteed.
Does the maturity estimate include past deposits?
Enter the latest current balance to represent past deposits and credited interest. Future deposits are shown separately.
Is PPF the same as a market-linked investment?
No. PPF is a government small-savings scheme. For a market-return scenario, compare the lumpsum calculator or SIP calculator without treating their assumed returns as guaranteed.
