A PPF Calculator is an online tool that helps you estimate the maturity value, total interest earned, and final returns on your Public Provident Fund investment based on the current interest rate 7.1% p.a. for Q2 FY26-27 and tenure. It simplifies long-term planning by showing how your annual contributions compound, helping you make informed, tax-efficient savings decisions.
A PPF calculator estimates an investor’s PPF maturity value, accrued interest, and overall returns on the overall investment based on the latest PPF interest rate and the duration. It helps investors plan their investments, project earnings over 15 years, and maximise returns by making deposits before the 5th of every month to benefit from maximum interest accumulation.
Using a PPF interest calculator simplifies financial planning, helping investors make informed decisions and maximise their savings.

Since the PPF interest rate is set by the Government and compounded annually, manually calculating maturity can become complex. The calculator automates the entire process instantly.
A PPF calculator uses a formula similar to the one used to calculate an annuity's future value. Simply put, it calculates the future value of your investment based on the annual PPF contribution and the prevailing interest rate.
The calculation formula that a PPF calculator uses is as follows:
M = P [({(1+i)^n}-1)/i]
Where,
Let’s say, if you invest ₹1,50,000 every year for 15 years:
By using this formula M = P [({(1+i)^n}-1)/i] the calculator will automatically show
PPF Calculator Example Table:
The concept of compounding and how it works in favour of an investor in PPF calculations can be explained with the following table, which highlights the PPF interest earned, the principal invested, and the PPF maturity value for 15, 20, and 30-year tenures.
| Investment Period | Total PPF Investment | Total Interest Earned | Maturity Value |
| 15 years | Rs 1.5 lakh | Rs 18,18,209 | Rs 40,68,209 |
| 20 years | Rs 1.5 lakh | Rs 36,58,288 | Rs 66,58,288 |
| 30 years | Rs 1.5 lakh | Rs 1,09,50,911 | Rs 1,54,50,911 |
In this PPF calculation example, it is assumed that the annual investment amount is Rs 1,50,000 and the latest PPF interest rate is 7.1% per annum (the current PPF interest rate for Q2 FY 2026-27).
The above example highlights the power of compounding when investing in PPF, your maturity amount rises from Rs 40 lakh to Rs 1 crore merely by investing Rs. 1.5 lakh over 15 years to 30 years.
A PPF calculator offers several benefits for smart financial planning, such as
Loan Against PPF: You can take a loan against your PPF account from year 3 to year 6 of account opening. The loan amount is limited to a percentage of the balance available at the end of the second preceding year.
Partial Withdrawal: Partial withdrawals are allowed from the 7th financial year onwards, subject to certain limits based on the balance at the end of the 4th preceding year.
Full Withdrawal: The full PPF balance can be withdrawn only after 15 years from maturity, unless extended in 5-year blocks.
The Public Provident Fund (PPF) is one of the most tax-efficient investment options in India, offering benefits under the Exempt-Exempt-Exempt (EEE) tax regime. This means that your investment, the interest earned, and the maturity proceeds are all exempt from income tax, subject to the applicable provisions of the Income Tax Act.
Here’s how PPF helps you save tax:
| Feature | PPF | FD |
| Returns | Government-fixed, tax-free | Fixed, taxable |
| Risk | Very low | Very low |
| Tax benefits | EEE (tax-free) | Interest is taxable at investor's slab rate |

| Best for | Long-term retirement savings | Short-term savings |
| Feature | PPF (Public Provident Fund) | EPF (Employees’ Provident Fund) |
| Type | Voluntary long-term savings scheme | Mandatory retirement savings scheme for salaried employees |
| Eligibility | Any Indian resident individual | Salaried employees in EPF-registered organizations |
| Contribution | Minimum ₹500, max ₹1.5 lakh per year | 12% of basic salary + employer contribution |
| Interest Rate | Fixed by government (currently 7.1% p.a.) | Fixed by EPFO (revised periodically, generally similar range) |
| Tax Benefit | EEE (Exempt-Exempt-Exempt) | EEE (subject to conditions) |
| Lock-in Period | 15 years (extendable in 5-year blocks) | Till retirement or job change (partial withdrawal allowed) |
| Withdrawal Rules | Partial withdrawal after 6 years, full after maturity | Partial withdrawals allowed for specific needs (education, home, etc.) |
| Flexibility | High (self-managed investment) | Low (salary-linked, employer-controlled) |
| Best For | Long-term tax-free savings & wealth creation | Retirement corpus building for employees |
The PPF Calculator empowers you to plan smarter with precise maturity projections, helping you maximise tax-free returns at the current 7.1% interest rate. Start investing early, deposit before the 5th of each month, and watch compounding work in your favour over the long term.
