What Is a PPF Calculator?
A Public Provident Fund (PPF) is a government-backed, long-term savings scheme introduced in India in 1968, offering guaranteed compound interest and triple tax exemption. This PPF calculator models how your yearly contributions grow to maturity over a 15-year lock-in — extendable in 5-year blocks — and now supports 10 world currencies so anyone modeling a similar fixed-rate, government-backed savings goal can use it, not just Indian residents.
How to Use the PPF Calculator
- Pick your currency: choose INR for an India-accurate calculation, or another currency to model a similar fixed-rate savings plan.
- Enter your investment details: initial deposit, regular contribution amount, and whether you contribute monthly or yearly.
- Set the tenure and rate: drag the years slider (default 15) and confirm or edit the annual interest rate (default 7.1%).
- Hit Calculate: instantly see your maturity amount, total interest, tax savings, and a full year-by-year growth table — adjust any field and recalculate anytime.
The Math Formula & How PPF Works
PPF uses annual compounding. Each year, your existing balance plus that year's contribution earns interest at the current rate, and the interest itself starts earning interest the following year. In formula form:
Balance(year) = [Balance(year − 1) + Contribution] × (1 + Rate)
Repeated over the full tenure, this compounding is what this calculator runs behind the scenes for every year of your investment period, including any 5-year extension blocks you add.
Practical Example & Data Comparison
Say you open a PPF account with an initial deposit of ₹500 and contribute ₹1,500 every month at the default 7.1% rate for 15 years. Here's how the balance compounds at a few checkpoints:
| Year | Total Invested | Interest Earned So Far | Balance |
|---|---|---|---|
| Year 5 | 91,500 INR | 18,644 INR | 110,144 INR |
| Year 10 | 181,500 INR | 82,468 INR | 263,968 INR |
| Year 15 | 271,500 INR | 200,438 INR | 471,938 INR |
Figures are illustrative and rounded; use the live calculator above with your own numbers for an exact result, including tax savings and inflation-adjusted value.
