APY vs APR What’s the Difference and Which One Matters? (2026)
What Is APR?
APR (Annual Percentage Rate) is the annual interest rate stated without factoring in the effect of compounding. It represents the base rate a bank uses to calculate interest.
APR is the “advertised” rate. A savings account advertised at 5% APR means the bank’s base rate is 5% but if interest compounds monthly, you actually earn slightly more than 5% over the year.
For loans and credit cards, APR also often includes certain fees in addition to the interest rate, making it a more complete cost measure than a bare interest rate.
Where you see APR:
- Credit card interest rates
- Personal loan rates
- Mortgage rates
- Auto loan rates
What Is APY?
APY (Annual Percentage Yield) is the effective annual rate you actually earn on a savings product, after accounting for compounding. It is always equal to or higher than the APR.
APY gives you the real number. It reflects what your balance will actually be after one full year of compounding not what the stated rate implies.
Where you see APY:
- High-yield savings accounts
- Certificates of deposit (CDs)
- Money market accounts
- Checking accounts that earn interest

How APY Is Calculated from APR
APY = (1 + r/n)^n − 1
Where:
- r = APR (as a decimal)
- n = number of compounding periods per year
Example: A savings account offers 5% APR with monthly compounding.
APY = (1 + 0.05/12)^12 − 1 APY = (1.004167)^12 − 1 APY = 1.05116 − 1 APY = 5.116%
You advertise 5% but the account actually earns 5.116%. The difference is small in one year but meaningful over time and at larger balances.
APR to APY Conversion Table
Here is how APR converts to APY at different compounding frequencies:
At 5% APR:
| Compounding | APY |
| Annually | 5.000% |
| Semi-annually | 5.063% |
| Quarterly | 5.095% |
| Monthly | 5.116% |
| Daily | 5.127% |
At different rates (monthly compounding):
| APR | APY (monthly compounding) |
| 3% | 3.042% |
| 4% | 4.074% |
| 5% | 5.116% |
| 6% | 6.168% |
| 8% | 8.300% |
| 10% | 10.471% |
| 20% | 21.939% |
Note: At 20% APR (common for credit cards), the effective APY is nearly 22%. This is why carrying a credit card balance is so costly.
Real Dollar Impact Why APY Matters for Savings
You have $50,000 to deposit. Two banks offer different rates:
| Bank | Advertised Rate | Compounding | APY | Balance After 1 Year |
| Bank A | 5.00% APR | Annually | 5.000% | $52,500 |
| Bank B | 4.95% APR | Daily | 5.073% | $52,537 |
Bank B advertises a lower APR but its daily compounding makes the APY higher — and you end up with $37 more after one year. Over 5 years at these rates, Bank B produces approximately $250 more on the same deposit.
Always compare APY, not APR, when evaluating savings products.
APY vs APR for Credit Cards The Important Difference
For credit cards, the number quoted is almost always an APR — but credit cards compound monthly. This means the true cost of carrying a balance is higher than the stated APR.
Example: Credit card with 22% APR, compounded monthly:
- APY = (1 + 0.22/12)^12 − 1 = 24.36%
If you carry a $5,000 balance for a full year making no payments:
- Interest at 22% APR (if it didn’t compound): $1,100
- Actual interest with monthly compounding: $1,218
The extra $118 is the cost of compounding working against you.

APY vs APR for Mortgages
Mortgages are advertised with APR, but for home loans the APR is more useful than for savings because it includes additional costs lender fees, origination charges, and points — spread over the loan term.
When comparing mortgages:
- A lower interest rate with higher fees might have a higher APR than a slightly higher rate with no fees
- Use APR to compare the total cost of two mortgage offers fairly
- The mortgage APR does not compound the same way savings APY does
For mortgages, the APR is a standardized comparison tool not a compounding calculation.
Compound Interest Calculator and APY
Our Compound Interest Calculator uses your APR input and compounding frequency to show you the real growth of your money which is equivalent to computing the APY effect over your chosen time period.
To find what rate to enter:
- Use the APR for your input rate
- Select your compounding frequency (daily, monthly, etc.)
- The calculator shows you the true final balance including compounding
If you want to quickly convert APR to APY without calculating: enter your principal, the APR rate, 1 year, and your compounding frequency — the growth percentage shown equals your APY.
Quick Reference When to Use APR vs APY
| Situation | Use |
| Comparing two savings accounts | APY |
| Comparing CD offers | APY |
| Comparing credit card rates | APR (then calculate APY for true cost) |
| Comparing mortgage offers | APR (includes fees) |
| Comparing personal loan rates | APR |
| Comparing high-yield savings | APY |
| Calculating investment growth | APY (or use our calculator with APR + frequency) |
Frequently Asked Questions
What is the difference between APR and APY?
APR is the stated annual interest rate without compounding. APY is the effective annual rate after compounding is included. APY is always equal to or higher than APR. For savings products, APY tells you what you actually earn. For loans, APR is the standard comparison metric.
Which is better higher APY or higher APR?
For savings, you want the highest APY. For loans, you want the lowest APR. They measure different things for different products.
Why is APY higher than APR?
Because APY accounts for the effect of compound interest. Interest earned in earlier periods gets added to your balance and then earns more interest pushing your effective annual return above the stated APR.
Does APY include fees? No. APY only reflects the compounding of interest. It does not include account fees, maintenance charges, or other costs. Always check for fees separately when comparing savings products.
Is the APR on a credit card the same as APY?
No. Credit cards quote APR but compound monthly, making the true annual cost (the effective APY) higher. A 22% APR credit card has an effective APY of approximately 24.4%.
How do I calculate APY from APR?
Use the formula: APY = (1 + APR/n)^n − 1, where n is the number of compounding periods per year. For monthly compounding, n = 12. For daily compounding, n = 365.
If two savings accounts have the same APR, how do I compare them?
Calculate or request the APY. The account with more frequent compounding (daily vs monthly) will have a slightly higher APY meaning you earn more actual interest.
