What is this tool?

The Public Provident Fund (PPF) is a long-term, government-backed savings scheme introduced by the Government of India in 1968 under the Public Provident Fund Act. It is designed to encourage small savings among Indian citizens while providing attractive returns and significant tax benefits. A PPF account has a mandatory lock-in period of 15 years, after which the depositor can withdraw the full maturity amount. The current interest rate is 7.1% per annum (as of 2024-25), set by the Ministry of Finance and revised every quarter. The interest is calculated annually on the minimum balance between the 5th and the end of each month, and is credited to the account at the end of the financial year. The maximum annual contribution is Rs. 1.5 lakh, and contributions qualify for deduction under Section 80C of the Income Tax Act. PPF falls under the Exempt-Exempt-Exempt (EEE) category, meaning the principal investment, the interest earned and the maturity amount are all entirely tax-free — making it one of the most tax-efficient investment options in India. The maturity value is calculated using the compound interest formula M = P x (1+i) x (([1+i]^n - 1)/i), where P is the annual contribution, i is the annual interest rate in decimal form, and n is the number of years. For example, investing Rs. 1.5 lakh per year at 7.1% for 15 years yields a maturity value of approximately Rs. 40,68,209. After maturity, the account can be extended in blocks of 5 years indefinitely. For comparing PPF with other investment options, our compound interest calculator and SIP calculator are great companions. The ROI calculator and investment calculator provide broader return analysis, while the EPF calculator helps you evaluate the employee provident fund side of your retirement planning.

How it works

The PPF calculator takes three inputs — annual investment amount, interest rate (defaulting to 7.1%), and time period (defaulting to 15 years) — and applies the compound interest formula M = P x (1+i) x (([1+i]^n - 1)/i). Here, P is the annual contribution, i is the annual interest rate as a decimal (e.g. 0.071 for 7.1%), and n is the number of years. After computing the maturity value M, the calculator derives total invested = P x n and interest earned = M - total invested. These figures help you see how much of your final corpus comes from your own contributions versus the interest accrued. The reference table below shows how different annual PPF contributions grow over the standard 15-year term at 7.1% p.a.: | Annual Investment | Total Invested (15 yr) | Interest Earned | Maturity Value | |---|---|---|---| | Rs. 50,000 | Rs. 7,50,000 | Rs. 6,06,070 | Rs. 13,56,070 | | Rs. 1,00,000 | Rs. 15,00,000 | Rs. 12,12,139 | Rs. 27,12,139 | | Rs. 1,50,000 | Rs. 22,50,000 | Rs. 18,18,209 | Rs. 40,68,209 | As the table shows, consistently investing the maximum Rs. 1.5 lakh per year in PPF can build a tax-free corpus of over Rs. 40 lakhs after 15 years.

Frequently Asked Questions

What is PPF and who can open an account?

The Public Provident Fund (PPF) is a government-backed long-term savings scheme available to all Indian citizens. Any resident individual can open a PPF account at a post office or designated banks. Hindu Undivided Families (HUFs) and non-residents are not eligible. Only one PPF account is allowed per person.

What is the current PPF interest rate?

The PPF interest rate is set by the Ministry of Finance and revised every quarter. As of 2024-25, the rate is 7.1% per annum. The government reviews the rate based on prevailing economic conditions, so it may change in future quarters. Always check the current rate on the India Post or NSI website.

How much can I invest in PPF each year?

The minimum annual contribution is Rs. 500, and the maximum is Rs. 1.5 lakh per financial year. If you fail to deposit the minimum Rs. 500, a penalty of Rs. 50 per year applies. Contributions up to Rs. 1.5 lakh qualify for deduction under Section 80C of the Income Tax Act.

Are PPF returns taxable?

No. PPF enjoys Exempt-Exempt-Exempt (EEE) status: the principal contribution is tax-deductible under Section 80C, the interest earned is entirely tax-free, and the maturity amount is also exempt from tax. This makes PPF one of the most tax-efficient investment options available in India.

Can I withdraw my PPF money before 15 years?

PPF has a 15-year lock-in. However, partial withdrawals are allowed from the 7th financial year onwards, limited to 50% of the balance at the end of the 4th preceding year or the 1st preceding year, whichever is lower. You can also take a loan against your PPF balance between the 3rd and 6th financial years.

What happens after the 15-year PPF maturity?

After the 15-year lock-in period, you can withdraw the full maturity amount or extend the account in blocks of 5 years. There is no limit on the number of extensions. During the extension period, you can continue making contributions and earning tax-free returns, making PPF an excellent long-term retirement planning tool.

How does PPF compare to other investment options?

PPF offers the unique combination of sovereign guarantee, EEE tax benefits and a 7.1% interest rate, making it one of the safest and most tax-efficient options for long-term goals. However, the 15-year lock-in limits liquidity. For shorter horizons or higher returns, consider SIPs in mutual funds (use our SIP calculator), or the EPF for salaried employees. Diversifying across multiple instruments is recommended.

Tips & Advice

To get the most out of your PPF account, always deposit your annual contribution before the 5th of each month, because the interest is calculated on the minimum balance between the 5th and the last day of the month — depositing early ensures your contribution is included in the interest calculation for that month. Aim to invest the full Rs. 1.5 lakh each financial year to maximise both your returns and your Section 80C tax deduction. Remember that PPF has a 15-year lock-in, so only invest money you will not need in the medium term; however, partial withdrawals are allowed from the 7th year onwards, and you can take a loan against your PPF balance between the 3rd and 6th years. After the 15-year maturity, you can extend the account in 5-year blocks — this is an excellent way to continue earning tax-free returns, especially in retirement. The interest rate is revised quarterly by the government, so keep an eye on the current rate and adjust your financial planning accordingly. PPF is especially powerful when combined with other tools like SIPs and EPF as part of a diversified retirement strategy. Use our compound interest calculator and investment calculator to model different scenarios and ensure your overall portfolio is on track.
