If others' experiences are any indication, your score might go down lol.
Wait what

I've seen more than a few people that said their scores dropped after paying off a loan. If I remember correctly, there was some discussion about how it might damage the mix of credit. For optimal scoring, someone even suggested taking out a loan regularly if there are no other accounts like it. I can't remember the specifics on that suggestion though. Perhaps someone else will chime in.
Personally, I say don't worry about it. Yay for reducing debt!

Indeed.
A good example is: I refinanced my car in March of this year, and saw my scores drop about 20 points, maybe because of the AAoA drop, maybe not. Idk why actually.
Anyways, six months later and paying it down a bit, my scores have since recovered, plus some.

Exactly.
OP don't get discouraged, it's not a bad thing by all means. It's just don't expect your score to go up a lot by paying off debt. Because what you're doing in a sense is trading less debt and low utilization for payment history and AAoA. The bump down will be slight but in time it will recover and be positive.
UTL and AAoA is not effected.
Mix of credit will cause the hit. If you have a car loan, mortgage or other personal loans you won't take a hit.
At any rate, losing a high interest loan is always worth a few points, congrats!
