If I am to invest money into a regular bank?

I want to open a account with $5000 dollars what would be my best option , Im thinking about going with 5/3 bank??? I am looking for the best possible intrest rate that I can get.

You can compare the rates of various banks at

A regular bank account won't give you the best interest rate. They are fairly low interest rates. My advice is to open an account with paypal and sign up for the money market account. it's free, easy to do, is just like a bank account, and you have access to your money at all times.

What the hell is 5/3 bank?
But to the point your average money market account will pay about 3.5 to 4 % (a passbook account at a bank much less) and if you look the inflation rate is about 3.5 to 4 % (imagine that?) so while the governmet is printing money they are acctually imposing an extra tax on everybody that nobody seems to notice.
Oh and by the way that 3.5 to 4 % your earning just to stay in one place. You have to pay income taxes on it. LOL

Washington Mutual's CD rates are 6.5% right now which is amazing. If you can afford to let that money sit for a few months, that's your best bet.

Money Market accounts are also a good plan, but only if you have more than 10,000 these days.

WaMu actually is requiring that you have a checking account there as well, and there are usually fees associated with their checking products, so be sure to ask lots of questions before getting into a product.

I can propose you the higer rate than any bank!

Here are several suggestions. I do not have a financial interest in any of these websites. (This does not violate the Yahoo answers ban on solicitations as I have no financial interest)

Consider the the Vanguard Prime Money Market Fund with a current compound yield of ~3.8% APY.

If you are in a high tax bracket you may prefer their tax exempt money market funds:

Sometimes other institutions will have a higher teaser rate, but Vanguard tends to have the highest yields I've found over the long run. (Vanguard money markets are not FDIC insured, however.)

Bankrate.com provides links to CD's with high interest rates as well as high interest rate banks.

ING and HSBC often have rates close to Vanguard, and most of their products are FDIC insured. You can check these at the following links:

(If you are investing for a long period of time and are willing to accept some volatility, you should consider putting some money into no-load low-expense mutual funds. These are not guaranteed, but over the long run produce much higher returns.)
