The model above assumes the initial deposit is made at the beginning of a year, and each monthly deposit is made at the end of each month. The compounding interest formula does change slightly if you deposit at the beginning of at the end of each month. That said, over a long period of time, the difference in the amounts won’t be significant.

In other words, with compound interest, you earn interest on previously earned interest. Because of this, compounding interest makes the principal grow exponentially, meaning as interest accrues and the quantity of money increases, the rate of growth becomes faster.

As we compare the compound interest line in our graph to those for standard interest and no interest at all, it’s clear to see how compound interest

boosts the investment value over time. In our article about the compound interest formula, we go through the process of

how to use the formula step-by-step, and give some real-world examples of how to use it.

Over time, compounding interest will lead the initial investment to exponential growth. For example, say you have $100 in your savings account and it’s paying 10% in simple interest. That means the 10% interest rate applies only to your original principal amount of $100, so you earn $10 each year. At the end of the third year, $130 — compared to $133.10 in the compounded interest account. Any regular contributions, and whether you will make them monthly or annually. While you can earn compound interest without ever contributing another dollar, additional contributions will speed up the money’s growth.

How Does Compound Interest Grow Over Time?

Accounts that earn compound interest are often invested in the stock market, which means they carry some degree of risk. For that reason, experts recommend investing only money you won’t need for at least five years. The effects of compound interest are increasingly dramatic over time, so move the calculator’s slider to see how your interest will grow over how to do a breakeven analysis with fixed cost & variable cost five, 10, or even 30 years. However, you can get the best of both worlds — some degree of compound interest plus liquidity — in a high-yield savings account. When you invest in the stock market, you don’t earn an annual interest rate like you would with a savings account. Instead, you get a return based on how much your investment changes in value.

When interest compounding takes place, the effective annual rate becomes higher than the nominal annual interest rate. The more times the

interest is compounded within the year, the higher the effective annual interest rate will be. Use our interest calculator to calculate the possible growth of your savings and investments over time. We discuss what compound interest is and how it can help you reach your financial goals in our article below.

What is the compound annual growth rate (CAGR)?

With the compound interest formula, the account earns more interest in the next compounding period. Say in our previous example that we earned interest semiannually rather than annually. Because n represents the number of compounding periods, and we are compounding semiannually for five years, there will be 10 compounding periods. We multiply five years by a compounding frequency of two (twice per year) to arrive at the number of compounding periods.

Compounding interest is the addition of interest to money invested. It is the result of reinvesting interest so that interest in the next period is then earned on the money invested plus the previously accumulated interest. For example, the S&P 500 index has returned on average around 8% over a long period of time.

For an excellent savings account, look for one at a bank that compounds interest daily and doesn’t charge monthly fees. Remember that banks usually express their interest rates as an annual percentage yield (APY) to account for the compounding effect. Consistent investing over a long period of time can be an effective strategy to accumulate wealth.
