You can get impact factors for specific individual journal titles or for various journal titles in a particular subject category by accessing the Journal Citation Reports (JCR) database on the ISI Web of Knowledge platform. Do note that each JCR edition for a year is released in the following year in roughly June or July.

For example JCR 2013 was released in July 2014 and JCR 2014 is expected be released in June/July 2014.

More information on how the Journal Impact Factor is calculated. More detailed help on using JCR database.

1. Access  Journal Citation Reports

2. Select either JCR Science Edition or JCR Social Science Edition and the year.

3. You can choose to browse by Subject Category or Search for a specific journal.  

4. If you are looking for the ranking of the journal by impact factor in it the subject categories (e.g 70/120) the journal is given, search for the specific journal title then click in on the title.

5. Then in the next screen select 

Alternatives

 Not all journals have a Impact factor. New journals with less than 3 years of publication will definitely not have a impact factor. See journal selection process by Thompson Reuters

You can also try Scopus's compare journal function (click on the Compare button on the top row of buttons after login) which lists various other journal metrics like SNIP and SJR . Or try SCImago Journal & Country Rank . Please note though similar in objective these metrics are not directly comparable with ISI's impact factor.

Alternatively you can try the recent Google Scholar Metrics , this is Google's ranking of publications using the Google Scholar index. This uses metrics like H5 index and H5 Median. Please note that while you can search by journal title for the H5 index and you may be able to find it, it may not list the ranking within a category as currently Google Scholar Metrics only ranks the top 20 in each category. 

Again these metrics are not directly comparable with ISI's impact factor.
