What counts as a “good” APR will depend on factors such as the competing rates offered in the market, the prime interest rate set by the central bank, and the borrower’s own credit score. When prime rates are low, companies in competitive industries will sometimes offer very low APRs on their credit products, such as the 0% on car loans or lease options. Although these low rates might seem attractive, customers should verify whether these rates last for the full length of the product’s term, or whether they are simply introductory rates that will revert to a higher APR after a certain period has passed. Moreover, low APRs may only be available to customers with especially high credit scores.

With annual percentage yield you can compare a number of interest rates which have different compounding periods.

How to tell the difference between APR and APY?
The best way to understand the difference between the APR and APY is to consider a real-world example. Let's imagine that you are about to buy a car and you are looking for the best way to finance it with loans. You go to a bank which offers you an APR of 12% with interest to be paid monthly (the bank doesn't charge you any other cost besides the interest). It means that in every month you need to pay one-twelfth of the annual rate, which is 12 / 12 = 1% in a month. If we translate this scheme into APY, we get a slightly different yearly rate. As APY takes into account the effect of the compounding factor, the yearly rate is expressed as 1.01¹² - 1 = 0.1268. So, according to APY, the bank is charging you 12.68 % interest yearly.

How Annual Percentage Rate Works
- Every time an individual or entity borrows money in the form of a traditional loan (think borrowing to purchase a house, car, or other major financial expense), there is a cost for the privilege of borrowing money, known as interest. The annual percentage rate is the percentage of interest the borrower must pay on the loan, which ultimately adds up...
Fixed Apr vs. Variable Apr
- In the example above, the 5% annual percentage rate was fixed. That means that the APR remains constant throughout the entire term of the loan. APRs can change. They’re not tied to any index, and the change isn’t automatic. A lender is required to give advance notice to the borrower if the APR is going to change. The lender has the prerogative to adjust the annual percentage ra…
Getting The Annual Percentage Rate
- Individuals or businesses are not always on the paying end of the APR. When an individual or business maintains a deposit account at a financial institution, they can earn interest on their deposits. The bank or other financial institution pays the account holder interest because the bank is essentially borrowing the account holder’s money. In this scenario, the account holder will rec…
Final Word
- It’s important for any individual who borrows money to understand the rate and terms of their APR, including whether it’s fixed or variable. This enables the borrower to establish a budget, use their loan wisely, and make consistent payments toward both the principal loan balance and the interest for the privilege of borrowing money.

Apr vs. Annual Percentage Yield
- Though an APR only accounts for simple interest, the annual percentage yield (APY)takes compound interest into account. As a result, a loan’s APY is higher than its APR.

If you end up rolling these into your mortgage, your mortgage balance increases, as does …
Disadvantages of Annual Percentage Rate

For instance, the average annual impact of mortgage …
The Bottom Line

By calculating only the simple interest without periodic compounding, the APR gives borrowers and lenders a snapshot of how much interest they are earning or paying within a certain period of time. If someone is borrowing money, such as by using a credit card or applying for a mortgage, the AP…
