Are you confused about how to calculate the interest on a bank account for savings? If the answer is yes, don’t worry because many people don’t understand how the interest was calculated on their bank statements. Here we explain what you should know about savings account interest rates, how to calculate them, and how to make the most money out of your savings.

Banking Deposits and APY

The annual percentage yield (APY) is a method used to calculate compound interest on a savings account deposit. Basically, APY will allow a depositor to receive interest, on top of interest, that they’ve already accumulated. Having said that, it would be to the advantage of the depositor to choose a savings account that compounded interest on a more frequent basis. Why? Because, the more your money compounds interest, the more interest you will be able to make. In other words, daily compounding will make you more money than yearly compounding.

How Do I Calculate Interest on a Savings Account?

If you are anything like most people, when they see complicated formulas, they immediately become intimated. However, this formula looks more intimidating than it really is. Besides, don’t you want to get the best out of your savings account? If you answered yes, then keep reading, because here we will provide you with the steps on how to calculate interest on a savings account.

The formula for APY (interest rate) is as follows:

That means:

APY = (1 + interest rate/number of periods) ^ number of periods - 1

**(^ represents to the power of)

Example # 1 – Interest Rates Compounded Monthly

Interest Rate: 12%

Deposit Amt: $1,000

APY = (1 + 0.01)^12 – 1

APY = 1.1268 – 1

APY = 12.68%

1,000 X 0.1268 = $126.80

Therefore, the depositor earned an additional $126.80 in compound interest for a deposit of $1,000. This would bring the total deposit to $1,126.80.

Example # 2 – Interest Rate Compounded Yearly

Interest Rate: 12%

Deposit Amt: $1,000

APY = (1 + 0.12)^1 – 1

APY = 1.12 – 1

APY = 12%

$1,000 X .12 = $120

Likewise, if a depositor earned an additional $120 dollars in compound interest it would bring the total account balance to $1,120.

As you can see, depositors can use compounding interest to their advantage by choosing a bank that compounds interest on a more frequent basis. In fact, it is strongly suggested that you not only scrutinize the APY banking rate, but that you also consider the amount of times your interest is compounded. In other words, a person whose interest is compounded quarterly, has three additional times to earn interest - on top of interest - than the person who compounds yearly only.
