AThe super simple explanation
is a standardized way lenders show you how expensive it is to borrow money over a year.
For loans, usually includes the interest rate plus certain fees, giving a fuller picture than the interest rate alone.
For credit cards, and interest rate are usually the same number, since credit cards typically don't bundle origination fees into the rate.
A lower generally means borrowing costs you less over time.
BWhy does this even matter?
- Comparing APRs is one of the fastest ways to tell which loan or credit card offer is actually cheaper.
- A seemingly small APR difference can add up to a lot of money on a large loan like a mortgage or car loan.
- Understanding intro APR offers helps you avoid a nasty surprise when the promotional rate ends.
COkay, how does it work?
DShow me an example
Comparing two credit cards
Card A has an 18% APR and Card B has a 24% APR. If both have an unpaid $1,000 balance for a year, Card B will generally cost meaningfully more in interest than Card A, all else equal.
This is why it's worth checking the APR before choosing a card, especially if you expect to carry a balance sometimes.
Illustrative example with made-up people and numbers — not current rates or rules.
EWords you should know
- APR
- The yearly cost of borrowing money, shown as a percentage. It includes interest and some fees.
- Fixed APR
- An APR that stays the same over time.
- Variable APR
- An APR that can change over time, often tied to a benchmark rate.
- Intro APR
- A temporary, often 0%, promotional rate offered for a limited time before the regular APR applies.
- Penalty APR
- A higher APR that can kick in, often after a late payment, under the card's terms.
FCommon mistakes
- Comparing a loan's interest rate to a credit card's APR as if they're the same kind of number without checking what fees are or aren't included.
- Forgetting that an intro 0% APR period ends, and not planning to pay off the balance before then.
- Assuming a lower advertised APR always applies to you — your actual APR offer often depends on your credit history.
- Not noticing a card has a separate, higher APR for cash advances.
