FICO scores have no memory for past debt/ utilization.
In other words, your score is a snapshot of what is on your credit report(s) at the moment that you pull a score. If your balances have all been knocked down, then your score will reflect that, without any penalty (or reward) for formerly having had a lot of debt.
Congrats on getting on top of your debt! That's the only way to go in this day and age.
