What is APY?

APY is the yearly yield on savings after compounding. How it differs from APR, with a worked example on $5,000.

APY is the annual percentage yield: the yearly return on a savings product after compounding is included. It is the number you use to compare savings accounts.

Worked example

Five thousand dollars at 4.00 percent APY earns about $200 in a year if you leave it there. The same 4.00 percent quoted as a simple rate that compounds monthly is a slightly lower APY. Banks advertise APY so those two products can be compared.

Why it matters

APR and APY look alike. APR is the yearly cost of a loan. APY is the yearly yield on cash. Mixing them makes a savings account look like a credit card, or the other way around.

Questions people ask

Is a higher APY always better?

On cash you can reach this week, yes, after fees and after you confirm the account is insured. A promotional APY that drops in three months is not the same product as a regular one.

Does APY include fees?

Usually no. A monthly fee can erase the yield on a small balance. Subtract fees from the dollars earned, not from the advertised percent.

Is APY a guaranteed return?

It is the current yield on that deposit product. Banks can change the rate. It is not a stock return.
