What Is APY (Annual Percentage Yield)
Defining APY
APY is a financial term that reflects the total amount of interest you can earn or owe on an investment or loan within a year. It considers compounding, which is the process of earning interest on your interest, making it different from a simple annual interest rate.
The Implications of APY
Understanding APY is essential for making informed financial decisions. A higher APY on a savings account or certificate of deposit (CD) implies more earnings for the saver, while a high APY on a loan indicates a higher return for the lender.
Calculating APY
The APY Formula
The formula for calculating APY is as follows:
APY = (1 + r/n) ^ (n*t) – 1
Where:
- r = annual interest rate (in decimal form)
- n = number of times interest is compounded per year
- t = time the money is invested or borrowed for, in years
Consider a savings account with a 2.5% annual interest rate, compounded monthly. Using the APY formula above, you can determine that your APY is actually 2.53% ((1 + 0.025/12)^12) – 1).
Examples of APY in Everyday Banking
Savings Account with APY
Let’s say you open a savings account with an APY of 1.5%, and you deposit $10,000. This means after one year, you will earn approximately $150 in interest, raising your total balance to $10,150 ($10,000 + ($10,000 x 0.015), assuming the account compound annually. If the APY compounds daily, then the account would generate a higher return, in this case, $151.13.
Credit Card APR vs. APY
Credit cards typically advertise an Annual Percentage Rate (APR), which doesn’t take compounding into account. However, because interest is usually compounded daily on credit card balances, the effective interest rate (or APY) will be higher. For instance, if a credit card has an APR of 14%, the actual APY for lenders, factoring in daily compounding, is around 15%.
CDs and High-Yield Savings Accounts
Some banks offer CDs and high-yield savings accounts with higher APYs than traditional savings accounts. If a high-yield savings account offers an APY of 5.0%, a $5,000 deposit would yield approximately $250 in interest after one year, compared to $75 in a regular account with a 1.5% APY.
Key takeaways
- APY is a financial term that reflects the total interest earned or owed in a year.
- It is different from a simple annual interest rate as it takes into account the effects of compounding.
- Understanding APY helps in making informed decisions regarding investments and loans.
- The formula for calculating APY is: APY = (1 + r/n) ^ (n*t) – 1.
