PPF Calculator: Estimate Your Public Provident Fund Maturity

The Public Provident Fund (PPF) is a popular long-term, tax-saving savings scheme backed by the Government of India. A PPF calculator estimates how much your account could grow over the years.

How does PPF work?

You deposit money each year (between ₹500 and ₹1,50,000), and it earns interest that is compounded yearly. The basic lock-in period is 15 years, after which it can be extended in blocks of 5 years.

How is PPF interest calculated?

Interest is added once a year on your balance. Because it compounds, the later years grow much faster than the early years. The government sets and revises the PPF interest rate every quarter.

Example

Depositing ₹1,50,000 every year for 15 years at 7.1% grows to roughly ₹40.68 lakh. You deposited ₹22.5 lakh and earned about ₹18.18 lakh in interest.

Key points

• Minimum ₹500 and maximum ₹1,50,000 can be deposited per year.
• The interest rate changes every quarter — use the current rate.
• PPF offers tax benefits, which makes the effective return attractive.
