What APR means and how to use it
Last updated November 9, 2026
APR stands for annual percentage rate. It is the yearly cost of borrowing money, shown as a percentage. It is the number to use when you compare debts, and it is the number our planner asks for.
APR vs. interest rate
On a credit card, the APR and the interest rate are essentially the same thing. On loans such as mortgages, auto loans and personal loans, the APR can be higher than the stated interest rate because it includes certain lender fees, such as origination fees or mortgage points. That makes APR a better way to compare offers from different lenders.
APR is not the same as what you pay over a year
APR usually does not show the effect of compounding. A card with a 24% APR that charges interest monthly costs about 26.8% over a year if you carry the balance. Daily compounding pushes it a little higher. This is why paying a card down quickly matters more than the headline rate suggests.
Fixed and variable APR
- Fixed: stays the same unless the lender changes the terms. Most car loans, personal loans and many mortgages are fixed.
- Variable: moves with a benchmark rate. Many credit cards and some student loans and mortgages work this way. Update the rate in the planner when yours changes.
Why APR decides what to pay first
Every dollar you owe costs you its APR each year. A dollar on a 29% card costs far more than a dollar on a 4% loan. That is why the avalanche method, which targets the highest APR, tends to save the most money.
Where to find yours
Look at your latest statement or your online account. Credit card statements list the APR for purchases. Loan statements and paperwork show the interest rate, and loan documents list the APR as well.
Run your own numbers
Enter your balances, rates and payments to see which debt to pay first and when you could be debt-free.
