How Does Interest Work on a Savings Account? Interest on a savings account helps your money grow over time, often viewed as “free money” from your bank. It is calculated based on the account balance and interest rate, with some accounts offering compound interest that helps your savings grow faster. To make the most of your savings, it’s important to understand how interest is calculated and how it impacts your financial growth.
Types of Interest: Simple vs. Compound
There are two main types of interest: simple interest and compound interest. Each type affects how your savings increase over time.
What is Simple Interest?
Simple interest is calculated only on the original amount you deposit. You can calculate it using this formula:
Interest = Principal x Rate x Time.
When you place $1,000 into a savings account at a bank, you’ll receive interest on that amount. a 5% simple interest rate for one year, you would earn $50 in interest ($1,000 x 0.05 x 1). Simple interest is straightforward, but it is less common in savings accounts and grows slower than compound interest.
Understanding Compound Interest
Compound interest is calculated on both the original deposit and the interest that has already been added. In simple terms, it is “interest on interest.” Use this formula for compound interest:
A = P (1 + r/n)^(nt),
Where:
- A = the future value of the investment, including interest
- P = the principal amount
- r = the annual interest rate (in decimal)
- n = how often interest is compounded each year
- t = how many years the money is invested.
For example, if you deposit $1,000 in an account with a 5% interest rate compounded annually, you earn $50 in the first year, just like with simple interest. But in the second year, you earn interest on $1,050 (the principal plus the interest earned), which gives you more than $50. This effect can help increase your savings significantly over time.

APY vs. Interest Rate: Understanding Your Returns
It is important to know the difference between APY (Annual Percentage Yield) and the interest rate when looking at savings accounts.
What is Interest Rate?
The interest rate is the annual percentage for your account, but it does not show the effects of compounding. Several factors, like the economy and the Federal Reserve’s policies, can affect interest rates.
Importance of APY
APY gives you a clearer picture because it shows the total interest you would earn in a year, factoring in compounding. For example, an account with a 5% interest rate compounded daily might give you an APY of 5.13%. This higher APY means better returns because of more frequent compounding.

Factors That Influence Savings Account Interest
Several factors can affect how much interest you earn on savings accounts:
- Account Type: Different savings accounts offer different interest rates. High-yield savings accounts usually provide better rates than standard accounts.
- Compounding Frequency: How often interest is compounded can change your total earnings. Interest can compound daily, monthly, quarterly, or annually. More frequent compounding often leads to higher returns. For example, $1,000 at 5% interest will earn more with daily compounding than with annual compounding.
- Bank or Credit Union Choice: Different financial institutions offer different interest rates. Online banks usually provide higher rates because they have lower operating costs than traditional banks. Credit unions can also offer competitive rates.
