If you open a CD account with your bank, what interest can you get?

You get what the bank is offering. Banks offer different interest rates depending on the length of the CD. The longer you contract for the bigger the interest rate.

You should check out banks to see what rates they are offering. You should also look into credit unions, on line banks and Saving and Loans.

Depends on the rates at the time at that particular bank. Right now around 4 or 5% for most major banks.

i understand CD is current account, if yes, in India some banks pay .5% interest if it is in foreign currency account. and for rupee account no interest is paid.

The highest rate I've personally seen is 5.1% at a major e-bank whose commercials you routinely see on the television. (I won't say the name because I've been given a "spam" violation for helping someone like you in an answer, but you can IM me if you can't find it yourself.)

My credit union is over 4%.
