Everyone seems to have an interest in earning more money. Most of us are continually looking for ways to boost our income and earn more for spending, saving, and paying down debt. However, it’s not always easy to add a zero or two to the end of a paycheck. Aside from getting a second job or asking for a raise, increasing what’s in your savings account can be a pretty difficult task.

In many cases, you don’t have to work 60 hours a week or beg your boss for an increase in pay. Almost every job field offers some sort of certification and many will boost your pay scale and have you earning more in a matter of months. Here’s a look at some of the most popular job certifications and the difference adding an acronym next to your name can have on your monthly take-home pay.
