What APR does to a balance you still owe

APR is not a personality score. It is the yearly rate a lender uses to add interest to what you still owe. Paid in full, many cards add none.

On a revolving card, interest is figured on the leftover balance. The minimum payment is built to keep the account current, not to finish the debt. The grace period is for people who pay the statement in full.

The $50 payment is not $50 of progress

A $2,000 balance at 22 percent APR is about $37 of interest in a month (2,000 times 0.22 divided by 12). A $50 minimum then cuts the balance by about $13. That is why the same card is still there two years later. The example is arithmetic, not a quote of anyone's current rate.

APR is the yearly rate. Interest is the dollar amount that rate adds. Mixing the two words is how a 22 percent card sounds like a $22 fee.

APR versus APY

APR is the yearly cost of a loan. APY is the yearly yield on savings after compounding. A savings APY and a card APR are not interchangeable, even when the percent looks similar.

A 0 percent intro APR is a timer. When the date hits, the regular APR applies to what is left. A transfer fee can eat part of the window before any interest does.

The grace period is a switch

If the statement is paid in full by the due date, new purchases on many cards accrue no interest during the grace period. Carry a balance, and that window often closes until the card is paid in full again.

Cash advances and some balance transfers usually have no grace period. The rate starts the day the cash moves.

Questions people ask

Does paying the minimum avoid interest?

No. The minimum usually includes the interest and a small piece of principal.

Is a lower APR always cheaper?

On the same balance, yes, after fees. A fee-heavy 0 percent transfer can still cost more than a slightly higher APR with no fee, depending on how fast you pay it.

Is APR the same as APY?

No. APR prices a loan. APY prices savings.
