🔍 What is APY?
APY stands for Annual Percentage Yield. It represents the total amount of interest earned in one year, accounting for the effect of compound interest.
In simpler terms: If you deposit $1,000 in a bank at a 5% APY, you’ll earn more than $50 in a year if the interest is compounded monthly, quarterly, or daily.
🧠 Why is APY Important in 2025?
In 2025, the interest rate environment is more dynamic than previous years. With rising inflation and digital banks offering competitive rates, savers need to compare real returns — not just nominal rates.
APY Helps You:
- Compare different savings accounts or certificates of deposit (CDs)
- Understand the true return after compounding
- Make smarter investment or savings decisions
⚙️ APY vs Interest Rate: What’s the Difference?
| Feature | Interest Rate | APY |
|---|---|---|
| Compounding Included | ❌ No | ✅ Yes |
| Real Return | ❌ Lower | ✅ Accurate |
| Best for | Loan Costs | Savings Comparison |
Example:
- 5% interest rate compounded monthly gives ~5.12% APY
- The higher the frequency of compounding, the greater the APY
📐 APY Formula (2025 Standard)
Here’s how APY is calculated in 2025:
iniCopyEditAPY = (1 + r/n)ⁿ - 1
Where:
r= annual interest rate (as a decimal)n= number of compounding periods per year
🔢 Example:
If your bank offers 6% annual interest compounded monthly:
makefileCopyEditAPY = (1 + 0.06/12)^12 - 1
APY = (1 + 0.005)^12 - 1
APY ≈ 0.0617 or 6.17%
So, the real yield is 6.17%, not 6%.
