Understanding APR vs APY
APR (Annual Percentage Rate) and APY (Annual Percentage Yield) are both measures of interest rates, but APR represents the yearly interest charged or earned without compounding, while APY includes the effects of compounding over a year. This means APY is typically higher than APR for the same nominal rate if interest is compounded. Understanding the difference helps consumers compare loans or investments more accurately and make informed financial decisions.

💡 Key Takeaways
- Distinguish APR (rate charged/earned per year, without compounding) from APY (rate including compounding).
- Understand that the more often interest is compounded, the higher the APY will be for the same nominal APR.
- Use APY to compare true earnings or costs across accounts and loans, since APR alone can be misleading.
- Be able to estimate APY from APR and compounding frequency to make informed everyday money choices.
❓ Frequently Asked Questions
What is APR?
APR, or annual percentage rate, is the yearly interest rate charged or earned. It does not account for compounding within the year.
What is APY?
APY, or annual percentage yield, is the interest you actually earn (or pay) over a year, including the effects of compounding.
Why does APY matter when comparing offers?
APY shows the real growth due to compounding. A higher APY means more earnings or lower costs over a year, even if the nominal rate appears lower.
How do you convert APR to APY?
If interest compounds n times per year, APY = (1 + APR/n)^n − 1. Use APR as a decimal (e.g., 8% → 0.08). Example: 8% APR with monthly compounding gives APY ≈ 8.33%.
Which should I compare for savings vs loans?
For savings, compare APY to see actual growth. For loans, compare APR to understand yearly cost. If needed, convert between them using the compounding frequency.
