📚 Understanding Compound Interest
A Compound Interest Calculator helps you calculate the growth of your investments with compounding. Unlike simple interest, compound interest earns "interest on interest," creating exponential growth over time. This is the principle behind long-term wealth creation through investments like PPF, EPF, mutual funds, and fixed deposits.
What is Compound Interest?
Compound interest is calculated on the initial principal and also on the accumulated interest of previous periods. Formula: A = P(1 + r/n)^(nt), where P is principal, r is annual rate, n is compounding frequency, and t is time in years. The more frequently interest compounds, the higher your returns.
Power of Compounding
Albert Einstein called compound interest the "eighth wonder of the world." A ₹1 lakh investment at 10% for 30 years with annual compounding grows to ₹17.45 lakhs. The same with monthly compounding becomes ₹19.84 lakhs. The key is starting early and staying invested long-term.
Compounding Frequencies
Different financial products use different compounding frequencies: Savings accounts typically compound quarterly, Fixed deposits compound quarterly, PPF compounds annually, and mutual funds effectively compound daily through NAV growth. Higher frequency = higher returns for the same interest rate.
❓ Compound Interest Calculator - FAQs
Q1: What is the compound interest formula?
The compound interest formula is: A = P(1 + r/n)^(nt). Where A = Final amount, P = Principal, r = Annual rate (decimal), n = Compounding frequency per year, t = Time in years. CI = A - P.
Q2: How does compounding frequency affect returns?
More frequent compounding yields higher returns. Daily compounding gives the highest return, followed by monthly, quarterly, semi-annual, and annual. The difference becomes significant over long periods.
Q3: Is this calculator free to use?
Yes! Our compound interest calculator is 100% free with no registration required. Use it unlimited times on any device.
Q4: What's the difference between simple and compound interest?
Simple interest is calculated only on principal. Compound interest is calculated on principal plus accumulated interest. Over long periods, compound interest yields significantly higher returns.
Q5: How to use the Rule of 72?
The Rule of 72 estimates doubling time: Years = 72 ÷ Interest Rate. At 8%, money doubles in 9 years. At 12%, in 6 years. This shows the power of higher returns.
