what bank account has the highest interest rate for the longest period of time?

Answer 1

Bank Accounts tend not to pay really high interest these days, but which bank accounts pay the Highest interest, of course, depends on your balance and whether or not you need access to your money. Higher balances will pay higher interest rates. Accounts that give you immediate access, don't pay as high as accounts that you can't access.

If you keep a small balance (in a bank account), open a Savings Account.
If you keep a moderately high balance - look at a money market account, if you need occasional access to your money. Look at a long term CD (5-10 years) if you do not need access to your money until maturity.

Here is an example of rates at one bank (American Bank), which actually are higher than many.
