On average, the shorter your first name, the more you will earn. In fact, the data show each extra letter “costs” you about $3,600 in annual salary.
In order to test the theory that shorter names always fare better, the site tested 24 pairs of full names against nicknames to see whether Bill or William, Chris or Christopher, Debbie or Deborah would win out. And in each case, the shorter name earned more — well, with one exception: Larry vs. Lawrence. If you’re still skeptical, the site also analyzed names that are spelled differently, such as Michele vs. Michelle, Sara vs. Sarah and Philip vs. Phillip. Again, fewer letters meant higher earnings.
