In a Glimpse How compound interest savings account works

No of your balance, a compound interest savings account can help you grow your money.

Capitalizing interest implies earning interest on both your savings and your interest. How fast your money grows is determined by the interest rate, the balance, and how often the interest is calculated.

## Opening a savings account is fun since interest boosts your money over time.

Compound interest is earned on savings accounts’ principal and interest.

Let’s see how compound interest works and the factors that can affect how fast your money grows.

#### Interest, the cost of borrowing money from a bank or lender, is expressed as an interest rate on credit cards and vehicle loans.

On the other hand, when financial institutions borrow money from you, they pay you interest. Usually, you are paid interest on deposit accounts, such as savings accounts, checking accounts, and money market accounts, in exchange for letting others use your money when they need it.

Savings accounts can accrue interest in one of two ways: through simple interest or compound interest. With simple interest, you earn interest only on the main one—the amount of money you deposited in your account.

But compound interest allows you to earn interest not only from the principal but also from the interest already accumulated.

Let’s say that your bank applies compound interest to your account every month. After the first month, the bank pays interest on the principal. Next month, the bank pays interest on the principal plus the interest it had previously accumulated. From then on, interest continues to accumulate every month on the combined amount of your savings and the accumulated interest.

In short, you will earn more money in a compound interest account than in a simple interest account.

**How often does a savings account accrue compound interest?**

Interest might be calculated daily, monthly, quarterly, or annually.

Your account balance grows faster as interest is computed more often.

The amount of interest you earn every year, based on the total amount of interest accrued and how often interest is calculated, is expressed as the annual rate of return, or APY. APY and earnings increase with interest calculation frequency.

**How is compound interest calculated?**

An online compound interest calculator can help you calculate the numbers, but you can also do the mathematical calculations yourself. This is the equation for calculating compound interest.

The following is an example to help you see the future value of your savings account.

Let’s say that you open an account with an initial deposit of $2,000 (this would be the main one, or **P**). If you have an annual interest rate of 2%, then **R = 0.02.** N = 12 if your bank calculates interest once a month.Let’s say you want to calculate how much money you will have in savings after two years (**T = 2).**

His equation would look like this:

**A = 2,000 (1 + 0.02/12) (12 x 2). **At the end of the two years, assuming that you have not withdrawn money or made deposits in the account, you would have $2,081.55. Since his original deposit was $2,000, he would have earned $81.55 in interest.

**Factors that affect how much interest can accrue**

There are a variety of factors that can influence how much interest you can earn and how quickly you can earn it.

These are some of those factors.

**The amount of money in your account**

In general, the more money you have in your savings account, the more interest will accrue over time. Making recurring deposits will result in accruing interest on a higher balance, while withdrawing money will result in interest accumulation on a smaller balance. In other words, it is beneficial to keep the money in the account.

**Your interest rate**

Your annual rate of return, or APY, may change over time, especially if the U.S. Federal Reserve raises or lowers the federal fund rate, so be sure to pay attention to any interest rate changes.

The frequency with which your financial institution calculates interest will also affect how much it earns—another reason why comparing APY between savings accounts is important.

**Account charges**

Account charges might lower your earnings or possibly make you spend more in fees than you earn in interest.

Depending on the institution and account, you may have to pay a monthly maintenance fee for exceeding the cash withdrawal limit, overdraft protection, ATM use, and more.

When creating an account, check the rules. Some banks allow you to avoid monthly installments by maintaining a minimum balance.

**What’s next?**

A compound interest savings account can help you save for a car down payment, an emergency fund, or other goals. Interest works in your favor, and you can access the funds in a time of need.

To help you find the savings account that best helps you meet your financial goals, look carefully and compare the annual performance rates, or APY, as well as the terms, of various institutions. Keep in mind that some online banks may offer you higher rates than conventional banks or credit unions. Choose a high-performance savings account with a higher interest rate.

Be sure the bank, credit union, or organization where you deposit funds is insured, and pay attention to the small writing that can indicate minimum deposits or balance limitations, how often interest is computed, and whether there is a fee—anything that may affect your long-term rate of return.
