APR
APR stands for annual percentage rate. It is often used for loans and credit products. Depending on the product and disclosure rules, it may include some costs beyond the nominal interest rate.

APR vs APY Explained
APR and APY both describe rates, but they are not always interchangeable. APR often describes an annualized borrowing cost, while APY shows an effective annual yield after compounding is included.
Updated: June 10, 2026
APY
APY stands for annual percentage yield. It shows how much a rate earns over a year after compounding is considered, assuming the interest remains in the account.
Why compounding matters
When interest compounds, interest can be added to the balance and then earn interest itself. That is why APY can be higher than a simple stated rate when interest compounds more than once per year. A savings account with a 4.00% stated annual rate compounded monthly has an APY slightly above 4.00% because interest is credited during the year.
Use the APR to APY calculator for direct conversion, or the effective annual rate calculator to see how a nominal rate changes with compounding. Use the compound interest calculator to explore how a rate, contribution pattern, and time horizon change estimated growth. For a plain-English foundation, read simple vs compound interest.
Where each rate usually appears
APR is commonly seen on loans, credit cards, mortgages, and other borrowing products. APY is commonly seen on savings accounts, certificates of deposit, and other deposit products. The direction matters: borrowers usually care about the cost of borrowing, while savers usually care about the effective yield after compounding.
Product disclosures can vary, so do not assume two numbers are comparable just because both are percentages. Check whether fees, compounding frequency, promotional periods, minimum balances, and introductory rates are included. Use the APY comparison calculator when comparing yield scenarios, or the money market calculator when APY, balance, and monthly deposits need to be modeled together.
Example: same stated rate, different compounding
Imagine two savings products both advertise a 5.00% stated annual rate. One compounds annually and the other compounds monthly. The monthly compounding option will have a slightly higher APY because interest is credited throughout the year and can earn additional interest. The difference may be small over one year, but it can become more noticeable with larger balances or longer time periods.
For loans, the comparison can be different. A loan APR may include certain fees, but it may not describe compounding the same way a deposit APY does. A credit card APR may be applied through a daily periodic rate. A mortgage APR may include some closing costs. Always compare the same type of product using the appropriate disclosure.
How to interpret rate claims
- For savings: APY is usually the better headline number for annual yield, but fees and minimum balances can reduce the practical benefit.
- For loans: APR can help compare borrowing offers, but payment size, term length, fees, and prepayment rules also matter.
- For promotions: check how long the promotional rate lasts and what rate applies afterward.
- For taxes: deposit interest may be taxable, so after-tax yield can be lower than the stated APY.

Assumptions and limits
APR and APY are disclosure tools, not complete financial plans. They may not capture account fees, early withdrawal penalties, changing rates, late fees, required balances, rewards programs, taxes, or behavioral factors such as carrying new balances. Some products use variable rates, so the rate shown today may not apply for the full year.
For borrowing comparisons, use the loan comparison calculator or read how to compare loans. For credit cards specifically, the credit card interest guide explains how APR can translate into monthly payoff cost.
Common mistakes
- Comparing a loan APR directly with a savings APY as if they answer the same question.
- Ignoring account fees, required balances, or early withdrawal penalties.
- Assuming a promotional APY or APR lasts for the full year.
- Forgetting that APR rules can differ by product type.
- Looking only at the rate and not the term, payment, liquidity, or risk.
How to read rate labels on offers
Rate labels are easiest to compare when you first identify the product type. Deposit accounts usually advertise APY because savers care about effective annual yield after compounding. Loans often advertise APR because borrowers need a standardized borrowing-cost label, but fees, compounding rules, and payoff timing still matter. Mixing those labels without context can make an offer look better or worse than it really is.
When an offer shows both a promotional rate and a standard rate, write down when the promotion ends and what balance or principal remains afterward. A high APY for a small capped deposit may matter less than a slightly lower APY on the full balance. A low introductory APR can become expensive if the balance remains after the promotional window.

FAQ
Is APY always better than APR?
No. They answer different questions. APY is common for savings yield; APR is common for borrowing cost. The better number depends on what you are comparing.
Should I compare APR to APY directly?
Be careful. Check product disclosures and whether fees, compounding, terms, and promotional periods are included.
Why is APY higher than the stated interest rate?
When interest compounds during the year, credited interest can earn additional interest. APY converts that effect into an annualized yield.
