Formula & Calculation Methodology
PPF computes interest annually using compounding formula F = P × [({(1 + i)^n} - 1) / i] × (1 + i) where i is annual interest rate / 100, and n is tenure in years.
F = P imes left[rac{(1 + i)^n - 1}{i}
ight] imes (1 + i)
Step-by-Step Worked Example
Annual Deposit: ₹1,50,000 | Tenure: 15 Years | Interest Rate: 7.1% p.a.
- Total Principal Deposited = ₹1,50,000 × 15 = ₹22,50,000
- Compounded Interest Earned over 15 Years = ₹18,18,209
- Total Guaranteed Tax-Free Maturity Value = ₹40,68,209
Result: Total Invested: ₹22,50,000 | Total Interest: ₹18,18,209 | Maturity Amount: ₹40,68,209 (100% Tax-Free under EEE)
What is Public Provident Fund (PPF)?
Public Provident Fund (PPF) is a premier government-backed, long-term small savings scheme in India designed to provide financial security during retirement while offering attractive tax benefits under Section 80C of the Income Tax Act.
PPF qualifies under the EEE (Exempt-Exempt-Exempt) tax status, meaning the invested amount, the interest earned, and the maturity proceeds are entirely exempt from Indian income tax.
PPF Rules, Eligibility & Extension Guidelines
The minimum annual deposit is ₹500, and the maximum allowed deposit is ₹1,50,000 per financial year.
The standard lock-in period is 15 complete financial years. After 15 years, you can extend your PPF account in blocks of 5 years with or without fresh contributions.
Frequently Asked Questions
What is the current PPF interest rate in India?
As announced by the Ministry of Finance, the PPF interest rate is 7.1% per annum, compounded annually and backed by a sovereign sovereign guarantee.
Is PPF maturity amount taxable?
No. PPF enjoys complete EEE (Exempt-Exempt-Exempt) status. Neither the annual interest nor the final maturity amount attracts any income tax.
When should I deposit money in PPF each month to get maximum interest?
Interest is calculated on the minimum balance between the 5th and the last day of each calendar month. Depositing on or before the 5th of every month maximizes your interest payout.
