Ready to take control of your money? Let’s break down the essentials simple, clear, and actionable with insights from Vietnam-UStrade.
1. What is annual percentage yield (APY)?
APY stands for Annual Percentage Yield. It shows how much money you can earn on your savings or investments over one year, including the effect of compounding interest. Compounding means you earn interest not only on your initial amount but also on the interest added over time.
The APY formula can be thought of as: how much your money would grow if interest gets added regularly throughout the year. For example, if you put $1,000 in an account with a 5% APY, after one year, you would have about $1,050, thanks to compounding.
APY is commonly used for:
- Savings accounts
- Certificates of Deposit (CDs)
- Money market accounts
Knowing the APY helps you understand the true return on your savings, which can be higher than the simple interest rate banks sometimes advertise.
2. What is annual percentage rate (APR)?
APR stands for Annual Percentage Rate. It represents the yearly cost of borrowing money, including interest and some fees. Unlike APY, APR usually does not include compound interest. It helps you understand what you will pay to lenders over the year.
The APR formula shows the total yearly rate you pay based on the loan amount, interest charges, and certain fees. For example, if you borrow $5,000 with a 7% APR, you’ll pay approximately $350 in interest and fees over a year, not counting compounding.
APR applies to many loans and credit products, such as:
- Credit cards ( learn how can you buy bitcoins with a credit card )
- Mortgages
- Auto loans
- Student loans
- Personal loans
Knowing the APR helps you compare loan offers and understand the real cost of borrowing money.
3. Annual percentage yield vs annual percentage rate explained
| Feature | APY | APR |
|---|---|---|
| What it measures | Earnings (savings/investment) | Cost of borrowing |
| Compounding | Included | Not included / simple interest |
| Typical uses | Savings accounts, CDs | Loans, credit cards |
| Who wants it higher/lower | Savers want higher; borrowers want lower | Borrowers want lower; savers n/a |
In simple terms, APY tells you how much you earn on your money with interest added on interest, while APR tells you what it costs to borrow money, usually without compounding. If you’re saving, a higher APY means more earnings. If you’re borrowing, a lower APR means less cost.
4. How are APY and APR calculated?
Knowing the formulas behind annual percentage yield vs annual percentage rate helps you make accurate comparisons and avoid misleading assumptions about interest and fees.
4.1. APY calculation
APY considers the interest rate and how often interest compounds each year. The formula is:
APY = (1 + r/n)n – 1
Where r = annual interest rate (decimal), and n = number of compounding periods per year. For example, if a savings account pays 5% interest compounded monthly (12 times a year), then:
APY = (1 + 0.05/12)12 – 1 ≈ 0.0512 or 5.12%
4.2. APR calculation
APR is simpler it is the annual interest rate plus any fees spread out over the year, without compounding. Lenders often add certain fees to interest to show a total borrowing cost.
For example, a $1,000 loan at 5% interest with $50 fees over one year:
APR = (Interest + Fees) / Principal = ($50 + $50) / $1,000 = 10%
Note that the same 5% interest rate can lead to a different amount paid depending on fees and compounding rules.
| Scenario | Amount at Year End | Explanation |
|---|---|---|
| $1,000 at 5% APY (compounded) | $1,051.16 | Earnings include compounding |
| $1,000 at 5% APR (no compounding) | $1,050.00 | Simple interest, no compounding |
This clear breakdown offers a practical difference between APR and APY with example, helping users visualize how fees and compounding influence real financial outcomes.
