The PPF Calculator (Public Provident Fund) helps you estimate the maturity amount of your PPF investment. PPF is a popular long-term savings scheme backed by the Government of India, offering tax-free returns and deductions under Section 80C. This PPF maturity calculator works for both annual lump sum and monthly contributions. Interest is compounded annually, and the lock-in period is 15 years (extendable in 5-year blocks). Select your currency (default INR) for accurate results.
PPF Calculation Formula (Annuity Due)
M = P × ((1+r)^(n+1) - (1+r)) / r
Where P = annual contribution, r = annual interest rate, n = number of years.
For monthly contributions, P = monthly amount × 12.
For example, investing ₹1,50,000 per year (the maximum tax-deductible limit) for 15 years at 7.1% interest yields approximately ₹40.68 lakhs at maturity. Total invested is ₹22.5 lakhs, so interest earned is ₹18.18 lakhs – completely tax-free. This calculator helps you plan your PPF investments for retirement, child education, or other long-term goals.

How to Maximize Your PPF Returns
Invest before the 5th of the month: Interest for that month is calculated on the lowest balance between the 5th and end of month. Depositing before 5th ensures full month's interest.
Maximize contribution early in the financial year: The earlier you deposit, the more months it earns interest.
Utilize the ₹1.5 lakh limit fully: For maximum tax benefit and corpus growth.
Extend PPF after 15 years: Continue with contributions – no upper limit on extension periods. The account continues to earn tax-free interest.
Reinvest maturity proceeds: If you don't need the funds, extend the account for another 5 years to let compounding work.
Common Mistakes to Avoid in PPF
Depositing after the 5th of the month: Loses interest for that month.
Not depositing every year: Account becomes discontinued if no deposit for a year (can be revived with penalty).
Exceeding ₹1.5 lakh: Excess amount does not earn interest and is not tax-deductible.
Withdrawing prematurely: Reduces compounding and tax benefits.
Not nominating: Legal hassle for heirs.
PPF for Retirement Planning
PPF is an excellent tool for building a tax-free retirement corpus. Since the lock-in is 15 years, starting early (e.g., age 25) allows multiple extensions until age 60. A PPF account opened at age 25, extended in 5-year blocks, can run for 35 years. At 7.1% interest, ₹1.5 lakh per year invested for 35 years would grow to over ₹2.2 crores – entirely tax-free. This makes PPF a core component of a conservative retirement portfolio.
Key Features of PPF (Summary)
Lock-in: 15 years (extendable in 5-year blocks without fresh contributions or with).
Interest: Set quarterly by government (compounded annually).
Tax benefits: 80C deduction up to ₹1.5 lakh; interest and maturity tax-free.
Minimum deposit: ₹500/year; maximum ₹1.5 lakh/year.
Loan facility: Available from 3rd to 6th year.
Partial withdrawal: Allowed from 7th financial year.
Power of compounding: Even small regular contributions grow significantly over 15+ years.
PPF vs. EPF – Which is Better?
EPF (Employees' Provident Fund) is mandatory for salaried employees (12% of basic salary). PPF is voluntary. EPF offers 8-8.5% returns (taxable if contributions exceed limits), while PPF offers ~7.1% but fully tax-free. For salaried individuals, both can coexist – EPF for mandatory savings, PPF for additional tax-free corpus. Use our calculator to compare.
Impact of Rate Changes on PPF Maturity
A 0.5% difference in PPF rate can significantly affect maturity. For ₹1.5 lakh/year for 15 years: at 7% → ₹39.7 lakhs; at 7.5% → ₹41.5 lakhs (difference of ₹1.8 lakhs). Our calculator lets you experiment with different rate scenarios.

Step‑by‑Step Manual Example
PPF: ₹1,50,000/year for 15 years @ 7.1%
Step 1: Annual contribution (P) = ₹1,50,000
Step 2: Rate (r) = 7.1% = 0.071, Years (n) = 15
Step 3: Formula = P × ((1+r)^(n+1) - (1+r)) / r
Step 4: (1.071)^16 = 3.006, (1.071) = 1.071
Step 5: (3.006 - 1.071) = 1.935
Step 6: 1.935 / 0.071 = 27.25
Step 7: Maturity = 1,50,000 × 27.25 = ₹40,87,500
Step 8: Total invested = 1,50,000 × 15 = ₹22,50,000
