APR — Annual Percentage Rate — is one of the most important numbers to understand when borrowing money. It's the true cost of a loan expressed as a yearly rate, and it's the number you should use when comparing loans, credit cards, and mortgages.
Simple definition: APR is the annual cost of borrowing money, including interest and fees, expressed as a percentage. The lower the APR, the less you pay to borrow.
The interest rate is just the cost of the loan principal. APR is broader — it includes the interest rate plus any fees the lender charges, such as origination fees, closing costs, or annual fees. This makes APR a more accurate picture of what a loan actually costs.
This is why you should always compare APRs, not just interest rates, when shopping for loans.
The rate stays the same for the life of the loan. Common in personal loans and mortgages. Predictable monthly payments.
The rate can change based on a benchmark index. Common in credit cards and some mortgages. Payments can go up or down.
The rate applied to everyday credit card purchases when you carry a balance.
A higher rate credit card issuers may apply after a missed or late payment. Can be as high as 29.99%.
A good APR depends on the type of loan and your credit score. Here are general benchmarks for 2025:
Even a small difference in APR can mean thousands of dollars over the life of a loan. On a $30,000 auto loan over 5 years, the difference between 5% and 8% APR is over $2,400 in total interest. Always shop around and compare APRs before signing.
