APR and APY

APR vs APY

APR is the yearly cost of borrowing. APY is the yearly return on savings, including interest earned on interest. A 4% rate paid monthly works out to a 4.07% APY.

APR
What borrowing costs in a year, including certain fees.
APY
What savings earn in a year, with compounding.
Same rate, different number
4% a year paid monthly is 4.07% APY.

1APR is for borrowing

You see it on cards, car loans and mortgages. Lower is better.

2APY is for saving

You see it on savings accounts and CDs. Higher is better, and it already counts compounding.

3Why APY is higher than the rate

Interest paid monthly starts earning interest itself. On $10,000 at 4% paid monthly, you earn about $407 in a year, not $400.
