APR stands for Annual Percentage Rate, and it shows the yearly cost of borrowing money as a percent. It helps students compare loans, credit cards, and other forms of credit using one standard number. APR matters because a small difference in percent can change how much you pay over time.
When you borrow money, APR is one of the first numbers to check before signing anything.
APR includes the interest rate and may also include certain lender fees, depending on the type of credit. A higher APR usually means borrowing is more expensive, especially if the balance is carried for many months or years. Credit cards often list APRs for purchases, cash advances, and late payments, while loans may list APR along with payment schedules.
Understanding APR helps you estimate costs, compare offers, and avoid debt that grows faster than expected.
Key Facts
- APR = Annual Percentage Rate, the yearly cost of borrowing expressed as a percent.
- Simple yearly interest estimate: Interest = Principal × APR × Time.
- For a 120.
- Monthly rate estimate = APR ÷ 12, so 24% APR is about 2% per month.
- Total repayment estimate = Principal + Interest + Fees.
- Lower APR usually means lower borrowing cost, but repayment time and fees also matter.
Vocabulary
- APR
- APR is the annual percentage rate that represents the yearly cost of borrowing money.
- Principal
- Principal is the original amount of money borrowed before interest or fees are added.
- Interest
- Interest is the cost paid to borrow money, usually calculated as a percentage of the balance.
- Fees
- Fees are extra charges a lender may add, such as origination fees, annual fees, or late payment fees.
- Credit Card Balance
- A credit card balance is the amount of money still owed on a credit card account.
Common Mistakes to Avoid
- Confusing APR with the monthly interest rate. APR is a yearly rate, so dividing by 12 gives only an approximate monthly rate.
- Ignoring fees when comparing loans. A loan with a lower interest rate can still cost more if its fees are high and included in the APR.
- Assuming the minimum payment avoids interest. Minimum payments reduce the balance slowly, so interest can keep adding up for a long time.
- Comparing only the APR and not the loan length. A lower APR over a much longer time can still lead to paying more total interest.
Practice Questions
- 1 You borrow $500 at a simple APR of 18% for 1 year. How much interest would you pay, and what is the total amount repaid?
- 2 A credit card has an APR of 24%. Estimate the monthly interest rate, then estimate one month of interest on a $300 balance.
- 3 Two loans have similar monthly payments. Loan A has a 9% APR for 3 years, and Loan B has a 7% APR for 6 years. Explain why Loan B might still cost more overall.
