Compound Interest

Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods, causing your money to grow exponentially over time.

Detailed Explanation

## What Is Compound Interest? Compound interest is often called the eighth wonder of the world, and for good reason. Unlike simple interest (which is calculated only on the original principal), compound interest is calculated on the principal plus all previously earned interest. This creates a snowball effect where your money grows faster and faster over time. ## The Formula A = P x (1 + r)^n Where: - A = Final amount - P = Principal (initial investment) - r = Interest rate per compounding period - n = Number of compounding periods ## How It Works in PPF PPF compounds annually at 7.1%. Here's what that means for Rs 1,00,000: - After 1 year: Rs 1,07,100 - After 5 years: Rs 1,40,826 - After 10 years: Rs 1,98,315 - After 15 years: Rs 2,79,019 Your money nearly triples in 15 years without you adding a single rupee. When you add Rs 1,50,000 every year, the compounding effect is even more dramatic because each new deposit starts its own compounding journey. ## Why Compounding Frequency Matters PPF compounds annually (once per year). Some instruments compound quarterly or monthly, which produces slightly higher returns at the same nominal rate. For example, 7.1% compounded quarterly gives a slightly higher effective rate than 7.1% compounded annually. However, PPF's annual compounding at 7.1% tax-free still beats most alternatives.

Partial Withdrawal

Partial withdrawal from PPF is allowed from the 7th financial year onwards, with the maximum amount being 50% of the balance from 4 years prior or the preceding year's balance, whichever is lower.

Loan Against PPF

PPF account holders can take a loan against their PPF balance from the 3rd to 6th financial year, borrowing up to 25% of the balance from two years prior at an interest rate of PPF rate plus 1%.

PPF Extension

After the 15-year maturity, a PPF account can be extended in 5-year blocks either with continued contributions or without, allowing the corpus to keep earning tax-free interest.

Tax-Free Returns

Tax-free returns mean the gains from an investment are not subject to income tax, allowing you to keep the full amount earned without any deductions for taxes.

Annual Deposit

The annual deposit in PPF refers to the total amount contributed to a PPF account in a financial year, with a minimum of Rs 500 and a maximum of Rs 1,50,000.

Interest Rate

The PPF interest rate is the annual rate at which your PPF balance earns returns, currently set at 7.1% per annum and revised quarterly by the Government of India based on government bond yields.

Sovereign Guarantee

A sovereign guarantee means the Government of India stands behind the PPF scheme, ensuring that both your principal and accumulated interest are fully protected regardless of economic conditions.
