How to Use the PPF Calculator
Enter your annual deposit (₹500–₹1,50,000), the current PPF interest rate, and tenure in years. The calculator projects maturity value and total interest — all computed locally in your browser.
- Annual deposit — total you contribute each financial year (lump sum or installments)
- Interest rate — government-set rate, reviewed quarterly (~7.1% in 2026)
- Tenure — minimum 15 years; extend in 5-year blocks after maturity
PPF Maturity Formula
Each year: Balance = (Previous balance + Deposit) × (1 + r)
r = annual rate (decimal). Interest is compounded annually on the lowest balance between the 5th and last day of each month.
Example: ₹1,50,000/year at 7.1% for 15 years → maturity ≈ ₹40.7 lakh (interest ≈ ₹18.2 lakh, all tax-free under EEE).
PPF Maturity Examples (7.1% p.a.)
| Annual deposit | 15 years | 20 years | 25 years |
|---|---|---|---|
| ₹50,000/yr | ₹13.6 L | ₹22.1 L | ₹34.2 L |
| ₹1,00,000/yr | ₹27.1 L | ₹44.2 L | ₹68.4 L |
| ₹1,50,000/yr (max) | ₹40.7 L | ₹66.3 L | ₹1.03 Cr |

Public Provident Fund (PPF) — complete guide
PPF is a government-backed long-term savings scheme with EEE tax status (exempt on investment, interest, and maturity). Current rate is set quarterly by the government (~7.1% as of 2026). Minimum annual deposit ₹500, maximum ₹1.5 lakh per financial year. Maturity is 15 years, extendable in 5-year blocks.
PPF suits risk-averse investors building a tax-free retirement corpus. Interest is compounded annually. Partial withdrawals allowed from year 7; loans against PPF balance available from year 3. PPF contributions qualify for Section 80C deduction up to ₹1.5 lakh.
PPF vs ELSS vs NPS
ELSS mutual funds offer Section 80C benefit with 3-year lock-in and equity upside but market risk. NPS offers additional ₹50,000 deduction under 80CCD(1B) with market-linked returns. PPF offers certainty and zero market risk at lower returns. A balanced portfolio often combines PPF (debt anchor) with equity SIPs for growth.
Maximizing PPF corpus
Invest before the 5th of each month to earn interest for that month (historical rule — confirm with your bank/post office). Investing ₹1.5 lakh lump sum on April 1 vs monthly ₹12,500 yields slightly higher returns due to earlier compounding. Use this calculator to compare annual vs monthly contribution patterns over 15 and 25 year horizons.
