Compound Interest
Compound interest is the process of earning interest not only on the original amount of money (the principal) but also on the interest that has already been added to it, resulting in exponential growth over time.
What Is Compound Interest?
Compound interest is a financial concept or monetary policy where interest is calculated on the principal amount and on the accumulated interest from previous periods. This means your money can grow at an increasing rate over time, as each interest payment contributes to a larger base for future interest calculations.
It’s a fundamental concept in savings accounts, investment returns, and loans, with the key difference that in investments, it works in your favor, while in debt, it can work against you.
A Brief History and Importance of Compound Interest
The concept of compounding has been known for centuries, often described as “interest on interest.” Albert Einstein famously called it the “eighth wonder of the world” because of its powerful effect on wealth growth.
In modern finance, compound interest is a core principle for retirement planning, long-term investing, and debt repayment strategies. It underpins financial products ranging from bonds and mutual funds to mortgages and credit cards.
How Compound Interest Is Used
In practice, compound interest is applied in savings accounts, reinvested dividends, and loan repayments. For example, if you invest $1,000 at 5% annual compound interest, you’ll earn $50 in the first year. In the second year, interest is calculated on $1,050, giving you $52.50, and the growth accelerates each year thereafter.
Compounding can occur annually, semi-annually, quarterly, monthly, or even daily, the more frequent the compounding, the faster the growth.
FAQ
What’s the difference between simple interest and compound interest?
Simple interest is calculated only on the principal, while compound interest is calculated on both the principal and accumulated interest.
How can I maximize compound interest benefits?
Start investing early, reinvest earnings, and choose accounts or investments with higher compounding frequency.
Can compound interest work against me?
Yes. In debt, compound interest can cause balances to grow quickly if unpaid, as in the case of credit card debt.
Does compounding always happen annually?
No. It can be applied monthly, daily, or even continuously, depending on the financial product.
