APY vs. interest rate: What’s the difference?
8 min read
Diving into the nuances of financial jargon may not be tops on your to-do list, but if you’re wanting to make smart money moves, brushing up on your banking vocab is a great first step. One example is understanding the difference between APY vs. interest rate.
Both words may have caught your eye in reference to earning money — but heads up! These terms are not interchangeable. In other words, Annual Percentage Yield (APY) is not the same as interest rate, although they are related.
To help you understand the ins and outs of these terms, along with the difference between APY and interest rate, the Spruce team is here to help you level up your financial knowledge as you look for savings account options. Plus, we’ll touch on concepts like APYE and APR in case, like many of us, those terms aren’t a regular feature in your everyday language. Yes, it’s a lot to take in, but don’t worry —we’ve got your back with simple to digest explanations and examples.

What is APY? What does APY mean?
APY is a measure of how much you’ve earned over a year, shown as a percentage. It applies when you put money in a savings account, money market, or other account that pays interest — and it includes compounding interest.
The compound interest piece is key to understanding what APY is. Compounded interest is when the interest you earn is added back to your account in set periods (daily, monthly, etc.). Then, with each dollar you earn, you have a little more money earning interest for you each period. In other words, you’re earning interest on interest.
The bottom line is the higher the APY, the more you earn!
What is interest rate?
You may find the term interest rate in a few scenarios and depending on the scenario, the definition of what an interest rate is will change. For example, an interest rate could apply to a loan or to an interest-bearing deposit account (such as a savings account) — both are shown using a percentage and are calculated on an annual basis.
In the case of a:
- loan, the interest rate is what the lender charges you when you borrow money as a percentage of the amount loaned.
- savings account, the interest rate is what the bank pays you as a percentage of the amount deposited (your principal).
If the interest isn’t compounded, it’s considered simple interest.
What’s the difference between interest rate vs. APY?
Now that you have interest rate and APY concepts under your belt, you can see both have to do with earning money based on a percentage of what you deposit. But if these words aren’t interchangeable, what is the difference between APY vs. interest rate?
In short, the distinction of interest rate vs. APY is compounding. When you earn money based on a simple interest rate it is referring to the rate of interest available each day while APY includes the interest earned and compounded based on the disclosed daily, monthly compounding schedule.
Check out our article on compounding interest for a deeper dive, but essentially, here’s the difference between APY and interest rate percentages:
- Interest Rate – this is the money paid by the bank as a daily rate on the money in your interest- bearing deposit account. The key is the simple interest rate percentage number does not include compounded interest.
- APY – this is the interest money you earned in your account calculated over one year. This percentage includes the compounded interest which was credited to your account.
In general, an APY for a given account will be somewhat higher than the account’s interest rate because the APY is accounting for the money earned over the full year..
Benefit of APY vs interest rate
If you think of compound interest as money being added to your initial pool of dollars, it’s easy to see that the pool will grow when your interest compounds, and as you’re saving, you’ll have more and more money working for you over time. T. Making your money work harder for you without lifting a finger? Yes, please!
One last thought on APY vs. interest rate: All accounts with an interest rate will have an APY, so it’s not really an either-or situation — rather it’s more about understanding how they’re related so you understand what’s being advertised.
Next, we should note that there are a couple of other terms that fit into the APY and interest discussion. Let’s take a quick pass over them.
APYE vs. APY
Where APY measures the rate that was earned over a year, APYE (annual percentage yield earned) measures the actual amount earned in a specific account periodically. That means the percentage can be unique to the account holder.
Why is that? APYE accounts for any deposits and withdrawals made during the statement period, which impacts the total interest earned for that period. Not everyone will make deposits and withdrawals at the same time.
The hypothetical example in the following table helps illustrate this. Let’s say Olivia and Dex both deposit $1,000 into an account; Olivia makes her deposit on June 1 and Dex makes their deposit on June 15.
| Olivia | Dex | |
| Average Daily Balance | $ 1,000.00 | $ 1,000.00 |
| Days in year | 365 | 365 |
| Days in month | 30 | 15 |
| Interest payment received | $3.00 | $ 1.50 |
| Actual Percentage Yield Earned | 3.71176% | 3.71459% |
So, while knowing the APY can help you compare your earning potential across different products and financial institutions, APYE helps you see how much you’ve actually earned once you’ve set up an account.
APR vs. APY
Earlier we mentioned that interest rates can apply to loans. Another term you’ll hear in respect to loans is Annual Percentage Rate (APR), which is the interest rate plus additional fees and costs (examples could be lender fees, closing costs or insurance.)
With one letter difference, it can be tricky to remember the difference between APR vs. APY.
- APR – This is a percentage you pay. Financial products with an APR include credit cards, auto loans, student loans, personal lines of credit, and more. A higher APR means you pay more.
- APY – This is a percentage you earn. Financial products with an APY include savings accounts, Certificates of Deposit (CDs), money market accounts or other interest-bearing accounts. A higher APY means you earn more.

What economic factors can affect my interest rate or APY?
We should point out that interest rates are not static as they are tied to other factors in the economy – namely the federal funds rate. The federal funds rate is the rate that banks charge for borrowing and lending money to other banks and financial institutions. This, in turn, affects the interest rate that banks charge or offer individual customers for loans, savings, and investments.
- For borrowers, a low interest rate is great because it means less money they need to pay back with their loans.
- For savers, however, a low interest rate means a lower APY, and less money earned. So while it’s important to look for banks and services offering high APY rates, just keep in mind that those rates aren’t set in stone and may change occasionally.
What else should you know about?
Now that we know how APY is affected by the federal funds rate, it’s also important to note that the interest you earn doesn’t all go straight to your pocket. Interest received on savings accounts, certificates of deposits, and money market accounts is considered taxable income by the IRS and must be reported each year. The interest is taxed at your earned income tax rate, but don’t worry — only the interest you receive is taxed, not your full balance.
