How This PPF Calculator Works
- • Monthly interest is calculated on the balance eligible under the 5th-day cutoff rule.
- • Interest accrues monthly but is credited to the account only at the end of each financial year.
- • Current-year uncredited interest does not compound within the same financial year.
- • Previously credited interest compounds in subsequent financial years.
- • Contributions made by the 5th earn interest for that month; contributions after the 5th earn from the following month onward.
- • Actual PPF outcomes depend on the notified interest rate, deposit dates, applicable contribution limits, and account conditions.
This calculator provides estimates for educational and informational purposes only. It is not financial, investment, accounting, or tax advice. The actual PPF maturity value depends on the interest rates notified by the Government of India, deposit dates, eligible balances, contribution limits, account conditions, and applicable scheme rules. Future interest rates may change. Check the latest official PPF rules and consult your bank, post office, or a qualified financial professional for account-specific guidance.

What Is a PPF Calculator?
A PPF Calculator is an online financial planning tool that helps you estimate the maturity value of your Public Provident Fund (PPF) account. By entering your annual investment, investment period, and assumed interest rate, you can estimate your total contributions, accumulated interest, and potential balance at maturity.
The Public Provident Fund is a long-term savings scheme backed by the Government of India. It is designed to encourage disciplined savings and is commonly used for retirement planning, long-term financial goals, and building a savings corpus over time. PPF interest rates are notified by the government and can be revised periodically.
A PPF calculator makes it easier to understand the effect of regular deposits and compound interest over a long investment period. You can compare different annual contribution amounts, test assumed interest rates, and estimate how your account balance may grow over the scheme's maturity period.
The result is an estimate rather than a guaranteed future balance. Your actual PPF maturity amount depends on deposit dates, the rates applicable during each period, account rules, and the duration of your investment.
What Is the Public Provident Fund Scheme?
The Public Provident Fund (PPF) is a government-backed small savings scheme available to eligible individuals in India. It has a long investment horizon and earns interest at the rate notified by the government for the applicable period.
An eligible individual can generally open a PPF account through a participating bank or post office. Accounts may also be opened by a guardian on behalf of an eligible minor, subject to scheme rules. Joint PPF accounts are not permitted.
| PPF Feature | General Rule |
|---|---|
| Minimum annual deposit | ₹500 per financial year |
| Maximum annual deposit | ₹1,50,000 per financial year, subject to the scheme's account aggregation rules |
| Deposit frequency | Lump sum or multiple permitted instalments |
| Original maturity framework | 15 complete financial years, counted under the scheme rules |
| Interest crediting | Credited annually using the prescribed interest calculation rules |
| Interest rate | Government-notified rate, which may change periodically |
These are general scheme features. Check the latest government notifications and your account provider's terms for the rules that apply to your account.
Current PPF Interest Rate
The PPF interest rate is determined by the Government of India and may be revised periodically. For the October–December 2026 quarter, the listed PPF interest rate is 7.1% per annum, compounded yearly.
Do not assume that this rate will remain unchanged throughout the entire investment period. Long-term PPF projections often use a constant rate for illustration, but actual interest earnings can differ when the government changes the rate in future quarters.
Important: Before using a PPF calculator, confirm that its assumed interest rate matches the rate you intend to model. A projection using 7.1% for all 15 years is a scenario, not a promise that the government rate will remain at 7.1%.
How Does a PPF Calculator Work?
A PPF calculator estimates the future value of your deposits and the interest accumulated over the selected period. It uses your contribution amount and an assumed rate of return to estimate the effect of compounding.
A simplified compound-growth formula for a starting amount is:
FV = P × (1 + r)^n
In this formula:
- FV: Future value of the starting deposit.
- P: Initial deposit or starting balance.
- r: Assumed annual interest rate expressed as a decimal.
- n: Number of annual compounding periods.
When you make regular contributions, the calculator must also account for the amount and timing of each deposit. A simple model for equal contributions made at the end of each annual period is:
FV = C × [((1 + r)^n − 1) / r]
For this contribution formula:
- C: Contribution made at the end of each annual period.
- r: Assumed annual return.
- n: Number of contributions or annual periods.
These formulas illustrate compound growth. They are not a complete substitute for the official PPF calculation method. PPF interest is calculated according to the scheme's monthly balance rules and credited annually. Deposit dates and changes in the notified rate can therefore affect the actual maturity amount.
How to Use the PPF Calculator
Follow these steps to estimate the growth of your Public Provident Fund investment.
- Enter your annual investment: Specify the amount you plan to contribute to your PPF account each financial year.
- Choose the investment period: Enter the number of years you want to project, taking the PPF maturity rules into account.
- Enter the assumed interest rate: Use the currently applicable rate or a hypothetical rate for scenario planning.
- Include your existing balance: If the calculator supports it, enter the amount already accumulated in your PPF account.
- Calculate your result: Review the projected balance, total contributions, and estimated interest earned.
- Compare scenarios: Change your annual contribution or assumed rate to understand how different scenarios might influence your projected savings.
Keep in mind that your contribution must stay within the applicable annual PPF deposit limits. The minimum yearly contribution and the rules for maintaining an account should also be considered.
PPF Calculator Example
Consider a simplified illustration in which an investor contributes ₹1,00,000 at the beginning of each annual period for 15 periods. For this example only, assume a constant annual rate of 7.1% and annual compounding.
| Input | Illustrative Value |
|---|---|
| Annual contribution | ₹1,00,000 |
| Investment period | 15 annual periods |
| Assumed interest rate | 7.1% per annum |
| Total contributions | ₹15,00,000 |
| Illustrative projected balance | Approximately ₹27.12 lakh |
| Illustrative growth above contributions | Approximately ₹12.12 lakh |
The projection illustrates how regular contributions can accumulate through compounding. The calculation assumes contributions at the beginning of each annual period and a constant rate for the entire illustration.
Actual PPF account interest is calculated under the scheme's monthly balance rules, and government-notified rates may change over time. The projected figure is therefore not an official maturity quotation. Your actual balance may be different.
Figures are rounded estimates for educational purposes, not a guaranteed return or investment recommendation.
How Compound Interest Helps Grow Your PPF
Compounding allows interest credited to an account to contribute to future interest earnings. As your PPF balance grows, interest can accumulate on the eligible balance, subject to the scheme's rules and applicable rates.
Over a long investment period, the effect of compounding can become significant. Regular contributions can add to that effect by increasing the balance on which future interest is calculated.
Regular Contributions
Consistent deposits help you build your savings gradually and make progress toward long-term financial goals.
Long-Term Growth
Leaving eligible savings invested for an extended period gives compound interest more time to contribute to account growth.
Interest on Accumulated Savings
Interest credited to the account adds to the balance and contributes to future growth under the scheme's calculation rules.
Disciplined Saving
An annual saving target can help you plan deposits and stay within the scheme's contribution limits.
PPF Deposit Rules and Limits
PPF accounts have specific minimum and maximum deposit limits. Understanding them is essential before planning your annual contributions.
Minimum Annual Deposit
A PPF account generally requires a minimum deposit of ₹500 in each financial year. If you do not meet the applicable minimum, the account may become inactive under the scheme rules. Restoration requirements and applicable charges should be checked with your account provider.
Maximum Annual Deposit
The general maximum deposit limit is ₹1,50,000 per financial year. Under the scheme, the limit for an individual includes deposits in the individual's own PPF account and an account opened on behalf of a minor. Deposits must also comply with the scheme's denomination and account rules.
Deposit Frequency
Deposits may be made as a lump sum or in multiple instalments during the financial year, subject to the applicable rules. You should decide on a contribution schedule that suits your financial circumstances and helps you stay within the limits.
Contribution reminder: The ₹1.5 lakh limit is an annual limit, not a monthly limit. Depositing more than the permitted amount does not create additional eligible PPF contributions.
When Should You Deposit Money Into PPF?
The timing of your deposit can affect the interest credited to your PPF account. Under the scheme's interest rules, interest for a month is based on the lowest balance between the close of the fifth day of the month and the end of that month.
As a result, money deposited on or before the fifth day of a month may qualify for interest for that month, provided the applicable account and scheme conditions are met. A deposit after the fifth day may not contribute to the eligible balance used for that month's interest calculation.
Some investors choose to deposit their planned annual contribution early in the financial year so it can remain in the account for longer. Others make deposits throughout the year. The benefit of a particular schedule depends on the amount, actual deposit date, balance, and applicable interest rate.
Confirm the eligible deposit date and interest treatment with your bank or post office. This explanation describes the general rule and does not guarantee interest for any particular transaction.
PPF Maturity Period and Extension Options
A PPF account ordinarily matures after 15 complete financial years, counted from the end of the financial year in which the account was opened, as prescribed by the scheme. The maturity date is therefore not necessarily the exact 15th anniversary of the account opening date.
At maturity, an account holder can review the options permitted by the scheme. Depending on the applicable rules and election requirements, the account may be closed and the balance withdrawn, or it may be extended in blocks of five years, with or without further contributions.
| Option | What It Means | What to Check |
|---|---|---|
| Close the account | Withdraw the eligible maturity balance. | Confirm the actual maturity date and closure procedure. |
| Extend with contributions | Continue the account under a permitted five-year extension block. | Follow the scheme's election deadline and deposit rules. |
| Extend without contributions | Retain the balance according to the applicable extension rules. | Check withdrawal conditions and current scheme rules. |
Extension choices can affect your access to money and future savings plan. Verify the applicable requirements with your account provider before maturity.
PPF Withdrawal and Loan Rules
PPF is intended primarily for long-term savings, but the scheme includes specific provisions for eligible loans and partial withdrawals. These provisions have timing restrictions and are not equivalent to unrestricted access to the account balance.
Loans Against PPF
Under the scheme framework, a loan facility is available during a defined period in the earlier years of the account. Eligibility and the amount available depend on the scheme's rules and the account balance in the prescribed reference year.
Partial Withdrawals
Partial withdrawals are generally permitted from the seventh financial year under the applicable conditions. The permitted amount and timing are governed by the PPF rules, not simply by the total balance displayed in a calculator.
Important: Do not treat the full projected PPF balance as money that is immediately available for withdrawal. Check eligibility, limits, reference balances, and the current scheme rules before relying on funds for a planned expense.
PPF vs. EPF vs. Fixed Deposit
PPF, Employees' Provident Fund (EPF), and fixed deposits serve different savings purposes. Their eligibility conditions, contribution rules, withdrawal terms, and tax treatment vary. Comparing these characteristics helps you choose the product that better suits your financial needs.
| Feature | PPF | EPF | Fixed Deposit |
|---|---|---|---|
| Typical purpose | Long-term individual savings | Retirement savings connected with eligible employment | Savings for a chosen deposit term |
| Contribution method | Permitted deposits within annual limits | Contributions under applicable employment and scheme rules | Usually a lump-sum deposit |
| Interest or return | Government-notified PPF rate | Rate governed by the applicable EPF framework | Rate and payout terms set by the institution |
| Access to money | Subject to PPF maturity, loan, and withdrawal rules | Subject to scheme withdrawal rules | Subject to the deposit's withdrawal terms |
| Contribution limits | Specific annual deposit limits | Rules depend on employment and the scheme | Product-specific minimums and terms |
These products are not interchangeable. Review the current rules, tax treatment, access restrictions, and institution-specific terms before choosing a savings option.
PPF Tax Benefits in India
PPF is commonly known for its favourable tax treatment. Subject to the applicable income-tax law and account rules, interest earned and eligible maturity proceeds are generally exempt from tax under the scheme's treatment.
The tax treatment of contributions depends on the rules applicable to the relevant tax year and the tax regime selected by the taxpayer. A contribution that qualifies for a deduction under one regime may not provide the same deduction under another. Eligibility and the available deduction limit should be verified before claiming any tax benefit.
A basic PPF calculator usually estimates account growth before considering an individual's wider tax position. If you are using the result for tax planning, check the latest guidance from the Income Tax Department or consult a qualified tax professional.

Limitations of a PPF Calculator
A PPF calculator is useful for financial planning, but the quality of its output depends on its inputs and assumptions. It may simplify the statutory interest calculation, use a constant rate for the entire period, or assume a contribution schedule different from the dates on which you actually deposit money.
- Changing interest rates: Future government-notified rates may be different from the rate used in today's estimate.
- Deposit timing: The actual dates of contributions influence eligible monthly balances under the PPF interest calculation rules.
- Contribution limits: A projection may assume annual contributions that exceed the applicable deposit limit unless the input is checked.
- Account rules: Loans, withdrawals, inactivity, extensions, and maturity dates may alter the amount available at a given time.
- Inflation: A nominal maturity balance does not directly measure future purchasing power.
For a realistic estimate, use the correct deposit schedule, verify the relevant government-notified rates, and check the account rules with your bank or post office.

How long is the PPF investment period?
The original PPF maturity framework is 15 complete financial years, counted from the end of the financial year in which the account was opened. The exact maturity date should be verified under the scheme rules.
How is PPF interest calculated?
Interest is calculated monthly using the lowest balance between the close of the fifth day of the month and the end of that month. Interest is credited to the account annually. Deposit dates and the notified rate can affect the amount earned.
When is the best time to deposit money in PPF?
A deposit made on or before the fifth day of a month may qualify for interest for that month under the applicable balance rules. Many savers consider depositing early in the financial year, but the benefit depends on the actual deposit date and account circumstances.
Is PPF interest compounded monthly or yearly?
PPF interest is calculated using the prescribed monthly balance method and credited annually. The scheme is commonly described as paying interest compounded yearly.
Can I deposit money in PPF every month?
Yes. PPF deposits can generally be made in multiple instalments during a financial year, subject to the scheme's deposit rules and the annual minimum and maximum limits.
Can I invest more than ₹1.5 lakh in PPF in one financial year?
The general permitted contribution limit is ₹1.5 lakh per financial year, subject to the scheme's account aggregation rules. Amounts above the permitted limit do not create additional eligible PPF contributions. Check the current rules and account-provider guidance.
Is PPF maturity tax-free?
PPF interest and eligible maturity proceeds are generally exempt under the scheme's tax treatment, subject to the applicable law. Tax benefits for contributions depend on current rules and the taxpayer's selected tax regime.
Can I withdraw money before PPF maturity?
Partial withdrawals may be permitted from the seventh financial year under the applicable rules. The eligible amount and timing depend on scheme conditions, so check your account eligibility before making plans.
Can I take a loan against my PPF balance?
The PPF scheme provides a loan facility during a specified period in the earlier years of the account. Eligibility and the available amount depend on the scheme rules and the balance in the prescribed reference period.
Can I extend my PPF account after 15 years?
An account can generally be extended in blocks of five years under the scheme rules. Extension options may allow continued contributions or retention of the balance without further deposits. Check the applicable election requirements and deadlines before maturity.
Can I open two PPF accounts in my own name?
Generally, an individual can hold only one PPF account in their own name under the scheme. An account for an eligible minor may be opened by a guardian, but the applicable aggregate contribution limit must be observed. Joint PPF accounts are not permitted.
Does the PPF interest rate remain fixed for 15 years?
No. The government-notified PPF interest rate can change periodically. A calculator that uses one rate throughout a 15-year projection produces a hypothetical estimate. Actual account growth depends on the rates applicable during the investment period.
Is PPF better than a fixed deposit?
The right choice depends on your goals, required access to money, term, interest rate, tax treatment, and risk preferences. PPF has scheme-specific contribution and withdrawal rules, while fixed deposits have institution- and product-specific terms.
Does a PPF Calculator show the exact maturity amount?
Not necessarily. A calculator provides an estimate based on its assumptions. The actual maturity amount depends on deposit dates, applicable interest rates, annual credits, withdrawals, and scheme rules.
Does PPF protect my savings against inflation?
PPF earns interest according to the notified rate, but the real purchasing power of the balance depends on inflation. If prices rise faster than the account's effective return over a period, purchasing power may decline despite an increase in the nominal balance.
Where can I check the official PPF rules?
You can consult the India Post savings schemes page and the National Savings Institute website for official scheme information and applicable rules.
