Real-Life Guide to Using the PPF Calculator
Public Provident Fund maturity. Use the examples and checks below to turn the number into a practical decision.
When this calculator is useful
Someone opening a new PPF account, or already contributing annually, who wants to project the maturity value after the mandatory 15-year lock-in, or work out how much to deposit each year to reach a target corpus.
For most people, the best way to use the PPF Calculator is to try the real case first, then change one input at a time. That makes the trade-off visible. For example, with a loan calculator you can change tenure while keeping the same rate; with an investment calculator you can change return assumption while keeping the same monthly contribution; with a health, education or measurement calculator you can check how much one input changes the final category.
The result should answer a practical question: Can I afford this? How much should I save? Is this score enough? Is this measurement within range? What is the safer or cheaper option? If the output does not answer the decision clearly, adjust the inputs until the scenario matches your real situation.
lightbulb Real-Life Example
Maxing out PPF for 15 years: A 30-year-old salaried employee deposits the full ₹1,50,000 on or before April 5th every year for 15 consecutive years.
1At an illustrative 7.1% p.a. (check the current government-notified PPF rate, revised every quarter), 15 annual deposits of ₹1,50,000 grow to approximately ₹40.5 lakh at maturity, made up of about ₹22.5 lakh principal and ₹18 lakh in tax-free interest.
2Now change one input, such as rate, time, quantity, unit or score, and compare the new result with the first one.
Depositing early in the financial year rather than late materially increases the compounding benefit accumulated over 15 years.
Practical Advice
Use the PPF Calculator as a planning tool, not just a number generator. Write down the inputs you used, because the final answer is meaningful only when you remember the assumptions behind it.
If the decision affects money, health, tax, safety, academics or legal compliance, keep a second check ready. That second check may be a bank quote, payslip, official rule, prescription, site measurement, mark sheet or invoice.
Common Mistakes
- Depositing more than ₹1.5 lakh in a financial year across all PPF accounts held in your name (including a minor child's account you operate) — the excess earns no interest and must be withdrawn.
- Depositing after the 5th of the month — PPF interest is calculated on the lowest balance between the 5th and end of the month, so a deposit made on the 10th misses that month's interest on the new amount.
- Treating 15 years as the only possible tenure, without modeling the 5-year extension blocks (with or without further contributions) that many account holders use to keep the balance compounding tax-free.
- Forgetting that partial withdrawals are allowed only from the 7th financial year onward, and loans against the balance only between the 3rd and 6th year — assuming an earlier withdrawal gives a misleading liquidity picture.
- Comparing PPF's post-tax return incorrectly against a taxable instrument's pre-tax rate, since PPF is EEE — contribution, interest, and maturity are all tax-free.
How to Interpret Results
The maturity value shown assumes the full annual contribution is made on or before April 5th every year for the entered tenure — depositing later in the year or skipping years will produce a lower actual maturity value than displayed.
A good interpretation looks at both the main result and the supporting values. If a page shows totals, ratios, categories, schedules or warnings, read those together instead of focusing only on the biggest number.
PPF Calculator FAQs
Useful answers for interpreting the output, avoiding mistakes and using the result responsibly.
How does the PPF calculator compute the maturity value?
It compounds your annual contribution at the current PPF interest rate for the number of years entered, crediting interest once a year based on the lowest monthly balance rule.
Why does the exact date I deposit within the month matter?
PPF interest for a given month is calculated on the lowest balance in the account between the 5th and the last day of that month, so depositing after the 5th means that month's deposit does not earn interest for that month.
Can I continue my PPF account after 15 years?
Yes, you can extend it indefinitely in blocks of 5 years, either continuing to contribute or leaving the balance untouched to keep earning interest without fresh deposits.
What is the maximum and minimum I can deposit each year?
The minimum is ₹500 and the maximum is ₹1.5 lakh per financial year; deposits can be made in a lump sum or in up to 12 installments.
When can I take a loan or make a partial withdrawal from my PPF account?
A loan against the balance is available between the 3rd and 6th financial year of the account, while partial withdrawals are permitted from the 7th financial year onward, subject to prescribed limits based on the balance.
Is the maturity amount really fully tax-free?
Yes, PPF follows the exempt-exempt-exempt structure — the annual contribution qualifies for Section 80C deduction, the interest earned is tax-free, and the maturity proceeds are also tax-free.
Can I open a PPF account for my child, and does that count toward my ₹1.5 lakh limit?
Yes, a parent or guardian can open an account for a minor, but the combined contribution across your own account and the minor's account cannot exceed ₹1.5 lakh in a financial year for tax deduction purposes.
What happens if I miss the yearly minimum deposit of ₹500?
The account becomes inactive (discontinued), and you will need to pay a small penalty along with the minimum due deposits for each missed year to reactivate it.
What is a PPF Calculator?
Public Provident Fund (PPF) is one of India's safest long-term tax-saving investments, backed by the government with a current interest rate of 7.1% p.a. Interest is compounded annually and fully tax-free, including the maturity amount.
PPF has a 15-year lock-in period and you can invest between ₹500 and ₹1.5 lakh per year. This calculator shows your total maturity amount and the interest earned over the chosen tenure — all updating live as you adjust the sliders.

Scenario: Ms. Priya Gupta, 25-year-old teacher from Bhopal — opens a PPF account and invests ₹1,50,000 per year (maximum limit) at 7.1% p.a. for 15 years to build a tax-free retirement corpus
1P = ₹1,50,000, r = 0.071, n = 15 years
2M = 1,50,000 × (1.071) × [(1.071)¹⁵ − 1] / 0.071
3Total Invested = ₹1,50,000 × 15 = ₹22,50,000
✓ Result: Maturity Value ≈ ₹40.68 Lakhs | Tax-free Interest Earned ≈ ₹18.18 Lakhs

Types of PPF
Understanding the different forms and phases of a PPF account
📘
Regular PPF
Opened by any Indian citizen (self). Minimum tenure of 15 years. All contributions, interest earned, and the maturity amount are completely tax-free under the EEE status.
Most Popular
👶
PPF for Minors
A parent or guardian can open a PPF account on behalf of a child under 18. The combined annual investment across the parent's and child's account cannot exceed ₹1.5L per year.
For Children
📆
PPF Extension (Block)
After 15 years, extend in 5-year blocks. With contributions: earns interest and new deposits continue. Without contributions: corpus earns interest with no new deposits needed — flexible for retirees.
Post-Maturity
💳
PPF Loan Facility
Borrow against PPF balance in years 3–6, at the PPF interest rate + 1%. Loan must be repaid within 36 months. You can borrow up to 25% of the balance at the end of the 2nd preceding year.
Liquidity
🏦
PPF Partial Withdrawal
From year 7 onwards, withdraw up to 50% of the balance at the end of year 4 or the year preceding the withdrawal year (whichever is lower). Only one withdrawal is permitted per financial year.
From Year 7
🔒
Discontinued PPF
If the annual minimum contribution (₹500) is missed in any year, the account becomes "discontinued." Revive it by paying ₹500 penalty per missed year plus the minimum ₹500 contribution for each missed year.

8 PPF Mistakes to Avoid
Small errors in timing or strategy can significantly reduce your tax-free PPF corpus
1
Not Depositing Before the 5th of the Month
PPF interest is calculated on the lowest balance between the 5th and last day of the month. If you deposit on the 6th or later, you lose that entire month's interest. Depositing between April 1–5 earns you 12 months of interest for the year.
2
Investing Less Than ₹1.5L/Year
PPF is the only instrument with full EEE (Exempt-Exempt-Exempt) status. By not maximising your contribution to ₹1.5 lakh, you miss out on the full Section 80C deduction of up to ₹46,800 per year (at the 30% tax slab), in addition to leaving compounding power on the table.
3
Skipping the Annual Contribution
Missing even one year's minimum deposit (₹500) makes the account inactive/discontinued. You must pay ₹50 penalty per missed year plus the minimum ₹500 contribution per year to revive it. Interest continues to accrue only on the existing balance — no new interest on the deficit.
4
Opening Multiple PPF Accounts
Only one PPF account is permitted per individual (plus one for a minor child). If the Income Tax Department or bank discovers a second account, it earns zero interest and the deposits are returned. The combined investment limit of ₹1.5L applies across both accounts.
5
Withdrawing Before Year 7
Partial withdrawals are only allowed from year 7 onwards. Before that, you can only take a loan (years 3–6). Planning short-term financial goals with PPF money is a mistake — use liquid funds or RDs for near-term goals instead.
6
Not Extending After 15 Years
Many people close their PPF at the 15-year mark and reinvest elsewhere. But an extended PPF with fresh contributions remains one of the best risk-free instruments available — tax-free, government-backed returns that beat most fixed-income alternatives in the same risk class.
7
Assuming the Interest Rate Is Fixed
PPF interest is set by the government every quarter and can change. It has historically ranged from 7.1% to 12%. Always model your projections using a conservative rate (like 7% or 7.1%) so you are not caught off guard by a rate revision. The sliders in this calculator help you stress-test different rate scenarios.
8
NRI Continuing PPF After Becoming NRI
Once you become an NRI, you cannot extend your PPF account after its maturity date. You can continue contributing until the existing maturity date, but no extensions are permitted. Plan your PPF contributions carefully if you are likely to move abroad — especially if maturity is approaching.
Benefits of PPF
- Triple tax exemption (EEE) — investment, interest, and maturity are all tax-free
- Government-backed safety — zero credit risk, unlike corporate FDs or market-linked products
- Section 80C deduction up to ₹1.5 lakh per year on your contribution
- Partial withdrawal allowed from Year 7 — useful for emergencies without full closure
- Loan against PPF balance available from Year 3 to Year 6 at low interest rates
- Extendable indefinitely in 5-year blocks — one of the best post-retirement debt instruments

Frequently Asked Questions
Detailed answers to the most common PPF questions
What is PPF and who can open it?
PPF (Public Provident Fund) is a long-term, government-backed savings scheme introduced in 1968 that offers guaranteed, tax-free returns. Any Indian resident individual can open a PPF account — at a post office, nationalised bank, or select private banks like HDFC and ICICI. NRIs, HUFs, and non-residents cannot open new accounts, though existing accounts can continue until maturity. You can open one account in your own name and one more in the name of a minor child you are the guardian of.
What is the EEE status of PPF?
EEE stands for Exempt-Exempt-Exempt — meaning PPF enjoys tax benefits at all three stages of the investment lifecycle. First, the contribution (up to ₹1.5 lakh/year) is deductible under Section 80C. Second, the interest credited each year is completely exempt from income tax. Third, the entire maturity amount — principal plus accumulated interest — is tax-free under Section 10(11). No other common savings instrument in India offers this triple exemption.
What is the minimum and maximum investment in PPF?
You must invest a minimum of ₹500 per financial year to keep the PPF account active — failing to do so makes the account inactive. The maximum annual contribution is ₹1,50,000 across all your PPF accounts combined (including a minor child's account if you are the guardian). You can make the deposit in one lump sum or up to 12 installments per year. Amounts above ₹1.5 lakh are returned without any interest.
Can I withdraw from PPF before 15 years?
Full premature closure is only allowed after 5 complete financial years from account opening, and only for specific reasons — life-threatening illness of the account holder, spouse, or dependent children; higher education of the account holder or children; or change in residency status (becoming an NRI). A 1% interest penalty is levied on premature closure. Partial withdrawals are available from year 7 onwards without any such restrictions (up to 50% of the eligible balance).
Can I take a loan against PPF?
Yes, you can take a loan against your PPF balance between the 3rd and 6th financial year from account opening. The loan amount cannot exceed 25% of the balance at the end of the 2nd year preceding the loan application year. The interest rate on the loan is PPF rate + 1% per annum. The loan must be repaid within 36 months; if not, the remaining balance attracts a higher interest rate of PPF rate + 6%. Only one loan is permitted at a time.
Can a minor have a PPF account?
Yes. A parent or legal guardian can open and operate a PPF account in the name of a minor child. The minor's account is managed by the guardian until the child turns 18, after which the child takes full control. Importantly, the combined annual contribution across the guardian's own PPF account and the minor's account must not exceed ₹1.5 lakh. Once the minor turns 18, they can continue the account independently with their own PAN.
Can NRI continue their PPF account?
An existing PPF account holder who subsequently becomes an NRI can continue contributing to and maintaining the account until its original 15-year maturity date. However, after maturity, an NRI cannot extend the account in 5-year blocks — the account must be closed. NRIs also cannot open a new PPF account. If you anticipate becoming an NRI, plan your PPF strategy around your likely maturity date to avoid losing out on post-maturity extensions.
What happens after the 15-year PPF maturity?
At maturity, you have three options: (1) Withdraw the entire corpus tax-free and close the account. (2) Extend the account for 5 years with fresh contributions — you continue investing up to ₹1.5 lakh/year and earn tax-free interest. (3) Extend without contributions — the corpus continues to earn interest at the prevailing PPF rate without you depositing anything new. Option 3 is ideal for retirees who want a risk-free, tax-free income without locking in new funds.
What if I miss depositing in a PPF year?
If you fail to deposit at least ₹500 in any financial year, your PPF account is classified as "discontinued" or inactive. The account continues to earn interest on the existing balance, but you lose the ability to take loans or make partial withdrawals until the account is revived. To reactivate it, you must pay a penalty of ₹50 per discontinued year plus the minimum deposit of ₹500 for each missed year. The overall 15-year maturity tenure is not extended — it runs from the original account opening date.
Is PPF a good investment compared to ELSS?
PPF and ELSS serve different investor profiles. PPF offers guaranteed, government-backed, tax-free returns with zero market risk — ideal for conservative investors or as the debt portion of a portfolio. ELSS is equity-linked (market risk), has a 3-year lock-in, and has historically delivered 12–14% CAGR — better for aggressive long-term wealth creation. Many financial planners recommend combining both: PPF for guaranteed EEE returns and ELSS for higher growth potential. The right mix depends on your risk tolerance and tax bracket.
How many PPF accounts can I have?
Each individual is allowed only one PPF account in their own name. If you accidentally open a second account (at a different bank or post office), the second account will not earn any interest and the deposits will be returned. Additionally, you may operate one PPF account as guardian of a minor child — but the combined investment in both accounts must stay within the ₹1.5 lakh annual cap. Spouses can each have their own PPF account independently.
How is PPF interest calculated — is it monthly or annual?
PPF interest is calculated on a monthly basis but credited to the account only once a year — at the end of each financial year (March 31). The interest for each month is based on the lowest balance in your account between the 5th and the last day of that month. This means if you deposit after the 5th of a month, you effectively lose that month's interest. To maximise returns, always deposit your yearly contribution between April 1–5, which ensures you earn interest for all 12 months of the financial year.
