Introduction

Public Provident Fund (PPF) is a 15-year government-backed scheme available at India Post and banks. Interest is tax-free and deposits qualify for Section 80C up to ₹1.5 lakh per financial year.

What this calculator does

Calculate PPF maturity with monthly or yearly deposits at current post office rate. You can deposit any time during the year between ₹500 and ₹1.5 lakh total per FY. This calculator supports both yearly lump-sum and equal monthly contributions. Actual PPF interest uses monthly balances; we approximate with annual interest credit after monthly contributions.

Who should use this calculator

India Post account holders and savers comparing small savings schemes. Use this tool if you want a clear estimate before speaking with a bank, post office branch, or tax advisor.

  • ₹1,50,000/year for 15 years at 7.1% → maturity ≈ ₹40.7 lakh
  • ₹10,000/month (₹1.2L/year) for 15 years at 7.1% → maturity ≈ ₹32.5 lakh
  • Minimum ₹500/year; maximum ₹1.5 lakh per financial year

Extension after 15 years

After maturity you can withdraw fully or extend in blocks of 5 years with or without fresh deposits. Use this calculator for the initial 15-year block, then plan extensions separately.

Benefits

  • PPF falls under EEE — deposits (80C), interest, and maturity are tax-free for resident Indians.

  • Ideal for long-term goals like retirement or child education alongside ELSS or NSC.

Limitations

  • Annual interest credit on monthly running balance (approximation)

  • Rate fixed for illustration

  • NRI accounts cannot be opened — PPF for residents only.

Tips

  • Deposit before the 5th of each month for slightly higher interest in real PPF accounts.

  • Extend in 5-year blocks after maturity without losing tax-free status.

Common mistakes

  • Exceeding ₹1.5 lakh total deposits in one financial year across PPF accounts.

  • Expecting partial withdrawal before year 7 except for specific allowed reasons.
