FICO does not consider income. Also, your FICO score increases more from paying down credit cards than installment loans. You may furthermore want to read Fico max out CC % and When to pay Credit Card for best Utilization.
I could easily imagine 50-100 points. It all depends on the rest of your specifics, and even then of course we can't be sure. I don't know about FICO, but in the world of Experian, credit cards are considered maxed-out when you have spent 90% or more of the credit limit, so that would work nicely in your favor.
I'd say you woIll see a decent bump in your score. 9% or less is optimal but you will still see an increase.
