When designing a logo, you should actually start off in black and white. There are a number of threads on here discussing why that is so.

I can tell you from personal experience that it's normal to provide a client with a black and white execution (for ads that might run in black and white publications, or for faxing), a spot color (Pantone) execution, for business cards, letterhead, etc., a CMYK version for 4-color ad work, as well as an RGB version for the web.

^^ In addition to urstwile's list, we also provide clients with a reversed version of the logo.

The answer is everything! You want you client to be able to use their new logo in any medium. Help them out and have it formatted for quick use.

RGB is provided for on-screen usage, such as TV and web sites. CMYK is formatted for printing the logo on physical media (paper, products, billboards, napkins, etc.). While the CMYK could be converted to grayscale for newspaper printing, it would be nice to include a grayscale or black & white version of the logo for that kind of printing too.

I usuall provide a client with different versions of their logo RGB, CMYK and spot colours for print. I also provide reverse logo for printing onto a black or dark background. File formats that I usuall provide are eps, pdf, jpg and tif. I will save as other files also if requested.

And since we're answering this again, Please create the logo in Illustrator, NOT Photoshop. I beg you, I'm so tired of asking companies for the vector files of their logos only to get jpgs, pdfs, tiffs, and eps (which are actually Photoshop files saved as .eps).

And yes, I forgot to include the reversed version, we do that as well.
