Entry Level Software Engineer Salary

What's a good starting salary for an entry level software engineer?

That depends.

There are many variables to this question, and I'm not going to discuss any of them here.

First, no one can decide your value but you. You'll get offers, and it's up to you to negotiate them. Hopefully, you do a fantastic job for yourself, but it can be difficult. My first software engineer job was a major step up from the previous salary. 

Important note:
NO ONE NEEDS TO KNOW YOUR CURRENT SALARY.

Politely deflect this question if it comes up, and strongly consider whether this is the right company for you. You know what salary you want. They know what they're willing to pay. That's ALL that matters.
