PPF Calculator

State-Guaranteed Savings with Public Provident Fund (PPF)

Our PPF Calculator is an advanced financial tool built to compute long-term savings projections under the Indian government\'s Public Provident Fund scheme. PPF is a highly popular, risk-free long-term sovereign debt savings scheme offering tax exemption under Section 80C.

The PPF Interest Compounding Schedule

Public Provident Fund interest is set quarterly by the Ministry of Finance and compounded annually. By law, there is a maximum yearly investment limit of ₹1,50,000 per individual, and a mandatory initial lock-in period of 15 years, after which the account can be extended in blocks of 5 years indefinitely.

The mathematical compound formula used by our engine assumes deposits are completed at the beginning of each fiscal year:
Maturity (F) = Yearly Deposit (A) * [((1 + Rate)^Years - 1) / Rate] * (1 + Rate)

Key Features:

• Sovereign Guarantee Limit Caps: Sliders are preconfigured to respect the standard government investment cap of ₹1.5 Lakhs annually.
• Granular Government Rate Adjuster: Slider defaults to the current benchmark rate of **7.1%** but enables adjustment to track sovereign rate shifts.
• Maturity Ratio Analytics: Progress bar tracking deposit principal vs. accumulated interest.
