₹12,500 Per Month PPF Calculator — 15 Year Corpus
Calculate 15-year maturity for ₹12,500 monthly PPF contribution at 7.1% — ₹40,68,209 tax-free. Rate × tenure comparison included.
A ₹12,500 per month PPF contribution works out to ₹1,50,000 annually — well below the ₹1.5 lakh cap — and because PPF returns are tax-free and the 15-year lock-in is non-negotiable, this vehicle remains a cornerstone of long-term, tax-efficient Indian retirement planning. At 7.1% per annum with annual compounding, a ₹12,500 monthly contribution (₹1,50,000 annually) over the mandatory 15-year PPF lock-in grows to about ₹40,68,209, with ₹18,18,209 earned as fully tax-free interest. PPF accounts can be extended in blocks of 5 years after maturity, and the extended blocks retain the EEE tax status — making PPF one of the most efficient long-duration compounding vehicles available to Indian salaried investors. Contributions must be deposited before the 5th of every month to count for that month's interest calculation — a small detail that materially affects the final corpus over 15+ years. The calculator is pre-filled at ₹12,500 per month — change the rate to model any future rate revision by the Ministry of Finance.

Understanding Your Investment Returns
This calculator projects your returns using compound interest, where your earnings generate their own earnings over time. The power of compounding means that even small regular investments can grow into substantial wealth over long periods. For example, investing just Rs 5,000 per month at 12% expected returns for 25 years can grow to over Rs 1 crore — of which only Rs 15 lakh is your own money and Rs 85 lakh is compounding returns. The key factors that determine your final corpus are: the amount invested, the rate of return, the duration of investment, and the frequency of compounding.
Important Considerations
Past returns do not guarantee future performance, especially for market-linked instruments like mutual funds and equities. The returns shown are estimates based on the rate you enter. Equity investments carry market risk but have historically delivered 12-15% CAGR over 15+ year periods in India. Fixed income options like PPF (7.1%) and FD (6-7.5%) offer lower but more predictable returns. Diversifying across asset classes — equity, debt, gold, and real estate — reduces overall portfolio risk while optimizing returns for your risk tolerance.

What is the maturity of a ₹12,500 per month PPF?
At 7.1% per annum, a ₹12,500 monthly PPF contribution (₹1,50,000 annually) matures to approximately ₹40,68,209 after the 15-year lock-in. Extending by two 5-year blocks (25 years total) grows this to ₹1,03,08,015 — all tax-free.
Is a ₹12,500 per month PPF contribution enough for tax saving?
Annual contribution of ₹1,50,000 fully uses the ₹1.5 lakh Section 80C ceiling under the old tax regime. Any contribution above ₹1.5 lakh annually earns no extra tax deduction but still compounds tax-free.
Can I withdraw from a ₹12,500 per month PPF before 15 years?
Partial withdrawal is permitted from the 7th financial year — up to 50% of the balance at the end of the 4th preceding year. For a ₹12,500 monthly PPF, this is a small but useful liquidity window for emergencies. Loans against balance are also available from years 3–6 at a modest spread over the PPF rate.
Should I invest ₹12,500 per month in PPF or ELSS?
PPF pays 7.1% tax-free and is debt-like (no market risk). ELSS aims for 12–14% CAGR with a 3-year lock-in but is fully equity. For a ₹12,500 monthly allocation, a common split is 50/50 — PPF for stability, ELSS for growth — capped within the ₹1.5 lakh 80C ceiling.
Does PPF rate change affect my ₹12,500 monthly contribution?
Yes. The Ministry of Finance revises PPF rates quarterly. Every past deposit earns interest at the rate in force during each quarter. A 50 bps rate cut on your ₹12,500 monthly PPF over 15 years reduces the final corpus by roughly ₹1,71,729 — meaningful but not catastrophic.
What is compound interest and why does it matter?
Compound interest means you earn interest on your interest, not just your principal. Over long periods, this creates exponential growth — even small regular investments can grow into substantial wealth over 15-25 years.
Is SIP better than lumpsum investment?
SIP invests a fixed amount monthly, averaging out market volatility through rupee cost averaging. Lumpsum works better when markets are low. For most investors, SIP builds discipline and removes the need to time the market.
