APY vs APR: What's the Difference and Which Matters?

By the USPaycheckGuide Editorial Team · Reviewed by Shaharyar Abid · Last updated September 28, 2026

APR and APY are two of the most confused acronyms in personal finance. Once you know the difference, comparing offers gets much easier.

1. What APR Means

APR, or annual percentage rate, is the yearly cost of borrowing expressed as a percentage. For loans and credit cards it includes the interest rate and, for many loans, certain fees. It does not include the effect of compounding within the year.

2. What APY Means

APY, or annual percentage yield, is the real rate of return on a deposit after compounding. It is what you use to compare savings accounts, money market accounts and CDs. Use our APY calculator to convert a stated rate.

3. A Quick Example

A savings account paying 4.00% compounded daily has an APY of about 4.08%. A loan with a 4.00% APR that compounds monthly effectively costs slightly more than 4.00% over the year, though the stated APR stays the same. That is why lenders like to quote APR and banks like to quote APY.

4. Which Number Should You Use?

When saving, compare APYs. When borrowing, compare APRs, and also compare fees and total cost. For credit cards, APR applies to balances carried past the grace period.

5. Fixed vs Variable Rates

Both APR and APY can be variable. Savings rates and credit card APRs often move with market rates, while many mortgages and personal loans have fixed rates for the full term.

6. Tips for Comparing Offers

Check minimum deposits, monthly fees, promotional periods and whether the rate is guaranteed. A slightly lower APY at an insured institution with no fees can beat a higher promotional rate that expires quickly.

7. Comparing Two Real Offers

Bank A offers a savings account with a 4.10% stated rate compounded daily (APY about 4.18%). Bank B offers 4.15% compounded annually (APY 4.15%). Bank A earns slightly more even though its stated rate looks lower, which is exactly why APY is the right number for savings. On a $20,000 balance that is about $6 more per year, a small amount that grows with balance and time.

8. Common Mistakes

• Comparing an APR on one product with an APY on another.
• Ignoring fees that reduce the real yield.
• Assuming a promotional APY lasts forever.

9. Key Takeaways

• Use APY to compare deposit accounts.
• Use APR and total cost to compare loans.
• Higher compounding frequency means a higher APY at the same stated rate.

10. Side-by-Side: APY vs APR at a Glance

A helpful memory trick: APY is the "yield" you earn, and APR is the "rate" you are charged. If you are earning, look for the highest APY; if you are borrowing, look for the lowest APR and the lowest total cost.

11. The Formula That Connects Them

APY = (1 + APR ÷ n)^n − 1, where n is the number of compounding periods per year. For a 5% nominal rate compounded monthly, APY = (1 + 0.05 ÷ 12)^12 − 1 = about 5.116%. If compounded daily, it is about 5.127%. The more frequent the compounding, the higher the APY for the same stated rate. This is why a credit card with a 24% APR compounded daily has an effective annual cost of about 27.1%, higher than the stated APR. Use our APY calculator to convert rates.

12. How to Compare Savings Accounts Using APY

1. Collect APYs from at least three banks or credit unions.
2. Check whether the APY applies to your balance or only above a threshold.
3. Check for fees, such as monthly maintenance charges.
4. Confirm insurance coverage (FDIC or NCUA).
5. Check transfer limits and how quickly you can access your money.
6. Choose the account with the best combination of APY, access and fees.

13. How to Compare Loans Using APR

APR includes the interest rate plus certain fees, such as origination fees or discount points, giving a broader measure of cost. For mortgages, APR helps compare offers with different fees. However, APR assumes you keep the loan for its full term, so if you plan to refinance or sell early, upfront fees matter more. Compare Loan Estimates line by line. For car loans, check APR and the total of payments; see the auto loan calculator. For personal loans, see personal loan vs credit card.

14. Common Misunderstandings

• "A 5% APR and a 5% APY are the same." They are not; APY is slightly higher than APR when there is compounding within the year.
• "Credit cards charge exactly their APR." Because interest compounds daily on balances you carry, the true annual cost is higher than the APR. See how credit card interest works.
• "A higher APY is always better." Only if fees, minimums and access are similar.
• "APY guarantees my earnings." Variable-rate accounts can change the APY at any time.

15. Putting It Into Practice

If you have a savings account earning 0.4% and another bank offers 4.2%, moving $15,000 could add roughly $570 a year in interest. If you also carry a credit card at 24% APR, using savings to pay it down saves far more than any savings account earns.

16. Practical Examples: Choosing the Right Number

Saving $8,000. Bank A advertises a 4.05% rate compounded monthly (APY about 4.13%). Bank B advertises 4.10% compounded annually (APY 4.10%). Bank A pays slightly more despite the lower stated rate, about $330 vs $328 in a year.

Borrowing $12,000. Lender A offers a 9.2% APR with no fees. Lender B offers 8.9% APR but with a 3% origination fee that is already included in the APR. The APRs show B as cheaper on paper, but if you plan to repay the loan in one year, the upfront fee makes B more expensive in practice. Always compare total dollars paid over your expected time frame.

Credit card. A card with a 22% APR compounds daily, so the effective annual rate is about 24.6%. That is the true cost of carrying a balance for a year without payments.

17. A Quick Reference Guide

• Saving? Use APY. Borrowing? Use APR.
• Divide an APR by 12 to estimate monthly interest on a loan, but remember interest on cards is daily.
• Convert APR to APY using the formula or the APY calculator.
• Ask whether the rate is fixed or variable.
• Include fees in your comparison.
• When two products have similar APRs, compare total dollars paid over your time horizon.

18. How compounding turns APR into APY

The formula is APY = (1 + APR / n)ⁿ - 1, where n is the number of compounding periods a year. The more often interest compounds, the higher the APY, though the difference between monthly and daily is small.

19. APR on loans includes fees

On mortgages and many installment loans, APR is required by the Truth in Lending Act to include certain finance charges, such as origination fees and points, spread over the life of the loan. That is why a mortgage can have a 6.5% interest rate and a 6.7% APR. Comparing APRs between lenders shows which loan costs more once fees are included, but only if you keep the loan for its full term; if you will refinance or sell in a few years, upfront fees matter more than the APR suggests.

Do savings accounts use APR or APY?

They generally advertise APY, and may also state an interest rate.

Why do credit cards use APR?

Regulations require cards to disclose APR, but daily compounding means the effective annual cost is higher.

Does APY include fees?

No. Fees reduce your actual return, so subtract them when comparing accounts.

Can APR be lower than APY on the same product?

For deposit accounts, the stated rate is usually lower than APY because of compounding. For loans, APR may be higher than the interest rate because it includes fees.

Why do banks advertise APY instead of APR?

Regulations require deposit accounts to disclose APY so consumers can compare accounts fairly, and APY is a higher number that looks better to savers.

Is APR the same as interest rate on a loan?

Not always. The interest rate is the cost of borrowing the principal, while APR includes certain fees and points, so APR is usually higher.

Is a mortgage quoted in APR or APY?

Mortgages are quoted with an interest rate and an APR that includes certain fees and points.

What is a good APY for a CD?

Good CD APYs depend on the term and market conditions; compare rates across insured institutions and consider laddering.

How do I convert a monthly interest rate into APR and APY?

Multiply the monthly rate by twelve to estimate the nominal APR. To find the APY, raise one plus the monthly rate to the twelfth power and subtract one. For example, a 0.4% monthly rate is about a 4.8% APR and about a 4.91% APY.

Why might two accounts with the same APY feel different?

Fees, minimum balances, transfer limits and customer service can differ even when yields are the same. Choose the account that fits how you use your money, not just the highest number.

What is the APY on 5% compounded monthly?

About 5.12%: (1 + 0.05/12)^12 - 1.

Is a 5% APY good?

It depends on current rates; compare with top high-yield savings and CD offers at the time, which move with Federal Reserve policy.

Do CDs quote APY?

Yes. Money market deposit accounts are deposit products, so banks quote their yield as APY.

Can a loan have the same APR and interest rate?

Yes, when there are no finance charges beyond interest, such as many credit cards and some personal loans with no fees.

What does a variable APY mean?

The bank can raise or lower the rate at any time; your actual yield over a year may differ from today's APY.

Is APY or APR better for savers?

APY, because it shows what you actually earn in a year once compounding is included.
