Path/degree recommendation for a 40 yr old man with no degree

[Freyo27]

Hi there, I’m a newbie here and I’m glad I found you guys. I’m 40 and I’ve been in the financial industry for 15 yrs in relationship management/sales within banking and wealth management. 
For my roles I never really needed a college degree but I have always wanted to completed as a personal fulfillment, potential career progression and to lead my children as example, but I’ve been deferring it and finally I’d like to put the work on it. 
I have completed probably like 16 credits when I attempted college years ago. I’m looking to get your advice on a degree that I can complete fast, super affordable and mostly online. This degree could be within the financial realm or any other degree you may recommend as long as is not too long, fast to complete it, etc. 
I thank you in advance for your support!
