What is compound interest?
For savers, the definition of compound interest is fundamental: it is the interest you earn on both your original money and on the interest you continue to accrue. Compound interest makes your savings grow faster over time.
In an account that pays compound interest, such as a standard savings account, the return is added to the original principal at the end of each compounding period, usually daily or monthly. Each time interest is calculated and added to the account, it results in a larger balance. With the compound interest formula, the account earns more interest in the next compounding period.
For example, if you put $10,000 in a savings account with a 4% annual return, compounded daily, you would earn $408 in interest the first year, $425 the second year, another $442 the third year, and so on. After 10 years of compounding, you would have earned a total of $4,918 in interest.
But remember: this is just an example. For long-term savings, there are better places than savings accounts to store your money, includingRoth or Traditional IRAsInCD's.
Compound investment return
When you invest in the stock market, you do not earn a fixed interest rate, but rather a return based on the change in the value of your investment. When the value of your investment increases, you get a return.
If you leave your money and invest the returns you earn in the market, these returns will grow over time in the same way as interest rates.
If you invested $10,000 in a mutual fund and the fund returned 6% over a year, that means you gained $600 and your investment would be worth $10,600. If you earn an average return of 6% the following year, that means your investment is worth $11,236.
Over the years, that money can really add up: If you kept that money in a retirement account for 30 years and earned an average return of 6%, your $10,000 would grow to more than $57,000.
In reality, the return on your investment will vary from year to year and even day to day. In the short term, riskier investments, such as stocks or mutual funds, can even lose value. But over a long time horizon, history shows that a diversified growth portfolio can return an average of 6% per year. Investment returns are usually represented by an annual return.
Compounding can help you achieve your long-term savings and investment goals, especially if you have the time to let it work its magic for years or decades. You can earn a lot more than you started with.

Compilation with additional contributions
As impressive as compound interest can be, progress toward savings goals also depends on making steady contributions.
Let's go back to the savings account example above and use the daily interest calculator to see the effect of regular contributions. We started with $10,000 and ended up with $4,918 in interest after 10 years in an account with a 4% annual return. But by putting an extra $100 into your savings account every month, you would end up with $29,648 after 10 years if added daily. Interest would be $7,648 on a total deposit of $22,000.
Frequently Asked Questions
How to calculate compound interest?
To calculate interest without a calculator, use the formula A=P(1+r/n)^nt, where:
A = final amount P = original balance = interest rate (as decimal) n = number of times interest is compounded in a specific time frame = time frame
What is the compound interest formula with an example?
Use the formula A=P(1+r/n)^nt. Let's e.g. Suppose you deposit $5,000 into a savings account that earns 3% annual interest and is paid out monthly. You calculate A = $5,000(1 + 0.03/12)^(12 x 1) and your ending balance is $5,152. So after one year you would have $5,152 in savings.
