What Is Compound Interest?

Compound interest is the interest calculated on the initial principal and the accumulated interest from previous periods. Often called "interest on interest," it's the reason why investments grow exponentially over time rather than linearly. This powerful concept is the cornerstone of wealth building and long-term financial success.

Compound Interest Formula

The compound interest formula is: A = P(1 + r/n)^(nt)

Where:

A = Final amount after time t
P = Principal amount (initial investment)
r = Annual interest rate (as decimal)
n = Number of times interest is compounded per year
t = Number of years

Best Investment Options for Compound Interest in India

Mutual Funds (SIP): Equity and debt funds with reinvestment of dividends
Fixed Deposits: Banks and corporate FDs with auto-renewal options
PPF (Public Provident Fund): 15-year lock-in with annual compounding
ELSS Funds: Tax-saving mutual funds with growth options
NSC (National Savings Certificate): Government-backed with compound returns
Corporate Bonds: High-grade bonds with reinvestment options
Unit Linked Insurance Plans: Market-linked returns with compounding

Compound vs Simple Interest

The key difference between compound and simple interest is that compound interest earns returns on previously earned interest, while simple interest only earns on the principal. Over time, this difference becomes substantial:

Simple Interest: Linear growth - same amount added each year
Compound Interest: Exponential growth - increasing amount each year
Long-term Impact: Compound interest significantly outperforms simple interest
Frequency Matters: More frequent compounding leads to higher returns

Maximizing Compound Interest Returns

Start investing early to benefit from longer compounding periods
Choose investments with higher compounding frequency (monthly vs annually)
Reinvest all dividends and interest to maintain compound effect
Make regular additional investments through SIP or similar methods
Avoid premature withdrawals that break the compounding cycle
Consider tax-efficient instruments to maximize net compound returns
Review and rebalance portfolio periodically for optimal growth

Compound Interest Calculator - FAQ

What is compound interest and how does it work?

Compound interest is interest calculated on both the initial principal and accumulated interest from previous periods. It works by reinvesting earned interest, causing your investment to grow exponentially over time rather than linearly.

How often is interest compounded in India?

Compounding frequency varies by investment type: Fixed deposits typically compound quarterly, PPF compounds annually, mutual funds compound daily, and some bonds compound half-yearly. Higher frequency generally means better returns.

Which investments offer compound interest returns?

In India, compound interest is available through Fixed Deposits, PPF, NSC, mutual funds (with dividend reinvestment), ELSS funds, corporate bonds, recurring deposits, and most savings schemes where returns are reinvested.

What's the difference between compound and simple interest?

Simple interest is calculated only on the principal amount, while compound interest is calculated on principal plus accumulated interest. Over time, compound interest grows exponentially and significantly outperforms simple interest.

How accurate is this compound interest calculator?

Our calculator uses the standard compound interest formula and provides mathematically accurate results. However, actual returns may vary due to market fluctuations, changing interest rates, and other real-world factors.

What is the Rule of 72 for compound interest?

The Rule of 72 estimates how long it takes to double your money: divide 72 by your annual interest rate. For example, at 12% annual return, your money doubles in approximately 72÷12 = 6 years.

Can I add regular investments to compound interest calculation?

Yes, our calculator includes options for regular additional investments (SIP-style). This dramatically increases your final amount as each new investment also starts compounding from the time it's invested.

Why does compounding frequency matter?

Higher compounding frequency means interest is calculated and added more often, giving you more opportunities for that interest to earn interest. Daily compounding typically yields better returns than annual compounding at the same interest rate.
