A PPF calculator monthly investment tool shows you exactly how much your Public Provident Fund grows over 15 years — interest, maturity amount, and tax savings included. Enter your monthly amount above and get instant results. No guesswork, no spreadsheets.
A PPF calculator monthly investment tool is an online calculator that computes your PPF maturity amount, total interest earned, and yearly balance when you invest a fixed amount every month instead of once a year.
PPF — Public Provident Fund — is a government-backed savings scheme in India. You can open a PPF account at SBI, HDFC, Post Office, or most major banks. The lock-in is 15 years, and the interest rate is currently 7.1% per annum, compounded annually.
Most people invest monthly because it fits their salary cycle. If you earn ₹10L per annum, putting aside ₹5,000–₹12,500 a month in PPF is practical and tax-smart. The ppf calculator monthly investment tool above handles all the math so you don’t have to.
You can learn more about PPF rules directly on the India Post website or check the Income Tax India portal for Section 80C deduction details.
📐 Formula: M = P × [((1 + r)^n – 1) / r] × (1 + r)
Where M = Maturity Amount, P = Monthly Investment, r = Monthly Interest Rate (annual rate ÷ 12), n = Total Months (15 years × 12 = 180)
The formula looks scary. But the PPF calculator monthly investment tool above does all of this in one click. Just type your monthly amount and hit calculate.
One important thing to know: PPF interest is calculated on the lowest balance between the 5th and last day of every month. So always invest before the 5th to earn interest for that month. Miss the 5th, and you lose one month’s interest.
Interest is credited once a year — at the end of March. But the calculation happens every month. This is why monthly investments typically beat a single lump-sum at year-end.
Here are three real scenarios using the ppf calculator monthly investment tool, at 7.1% annual rate over 15 years.
| Monthly | Invested | Interest | Maturity |
|---|---|---|---|
| ₹2,000 | ₹3.60L | ₹2.91L | ₹6.51L |
| ₹5,000 | ₹9.00L | ₹7.27L | ₹16.27L |
| ₹12,500 | ₹22.50L | ₹18.18L | ₹40.68L |
At ₹12,500/month, you hit the maximum annual PPF limit of ₹1.5 lakh. The maturity of ₹40.68L is 100% tax-free. That’s a clean ₹18L+ earned in interest — with zero tax. No FD or RD gives you this combination of safety and returns.
Use the free ppf calculator monthly investment tool above to run your own number.
Here’s how a ₹5,000/month investment grows each year. This is the power of compounding — slow at first, then it accelerates.
| Year | Invested | Balance |
|---|---|---|
| Year 1 | ₹60,000 | ₹62,600 |
| Year 3 | ₹1.80L | ₹2.01L |
| Year 5 | ₹3.00L | ₹3.60L |
| Year 10 | ₹6.00L | ₹8.66L |
| Year 15 | ₹9.00L | ₹16.27L |
Notice how the balance in Year 10 is already ₹8.66L — almost 45% above the amount invested. By Year 15, the interest earned nearly equals your total investment. That’s compounding doing the heavy work in the back half.
This is exactly why PPF rewards patience. Don’t withdraw early if you can avoid it.
More you invest monthly, bigger the corpus. But stay within ₹12,500/month (₹1.5L/year) — amounts above this earn no interest and no tax benefit.
The government reviews PPF rates every quarter. It’s been at 7.1% since April 2020. If it goes up, your actual maturity will be higher than the ppf calculator monthly investment estimate. If it drops, slightly lower.
Always deposit before the 5th of each month. Deposit on the 6th? You lose that month’s interest. Over 15 years, this small habit can cost or save you ₹30,000–₹50,000.
After 15 years, you can extend your PPF in 5-year blocks with or without fresh contributions. Extending with ₹12,500/month for 5 more years can add another ₹10–15 lakh to your corpus.

A: A PPF calculator monthly investment tool uses the compound interest formula to calculate your maturity amount based on how much you invest each month, the current 7.1% annual interest rate, and a 15-year (or custom) tenure. It shows your total investment, total interest earned, and final corpus instantly.
A: The maximum is ₹12,500 per month — which adds up to ₹1.5 lakh per year, the annual PPF limit. Any amount above ₹1.5L in a year earns no interest and no Section 80C tax deduction. The PPF calculator monthly investment tool automatically flags this limit.
A: Yes. PPF falls under the EEE (Exempt-Exempt-Exempt) category. Your investment qualifies for Section 80C deduction, the interest earned every year is tax-free, and the final maturity amount is completely tax-free. This makes PPF one of the best tax-saving instruments in India for FY2025–26.
A: Yes. The PPF interest rate is the same across all banks and post offices — SBI, HDFC, ICICI, Post Office. It’s set by the government each quarter. So the PPF calculator monthly investment results are identical regardless of where you hold the account.
A: Missing one month is fine — PPF only requires a minimum of ₹500 per year to keep the account active. But if you miss a full year, your account becomes inactive and you pay a ₹50 penalty per year to reactivate it. The PPF calculator monthly investment result assumes consistent deposits, so gaps will reduce your actual maturity amount slightly.
