A quick way to determine which savings account will pay the most interest would be to consult online financial sites such as NerdWallet or Bankrate. Each site shows various savings accounts so that you can compare them. Some of these website’s suggestions are not at typical banks. The way to compare them is to compare their annual percentage yield (APY). The APY is like the annual percentage rate (APR), but it does not include any account fees. The higher the APY, the higher the interest offered. If you can find a savings account that offers an APY higher than the national average savings account interest rate, it is often a good choice.
I would say, the best way and the fastest way, is to go to some banks and ask them how much interests they give you... then the bank that gives you the most interest, the bank that you are looking for.
