What would my household size be for the Affidavit of Support?

My fianceé just recently got her visa and is going to be coming over in May. We plan to get married soon after she gets here so we can get the AOS process going. I'm pretty much doing research and filling out all the paperwork now so that I can have all my ducks in a row when she gets here and it's stress free. So here's my situation. I currently live at home with my mom and my 3 brothers but plan to move out within the next few months but at the time of filing I'll still be here. Anyways, I don't support anyone in my household. The only one I'd be supporting is my fianceé. I alone don't make 125% so I have a co-sponsor who easily makes over this amount. It makes sense to me that my co-sponsor would have 3 dependents (herself, husband, my fianceé). Would I have to list 6 as the household size on my i864 (myself, fianceé, mom, 3 brothers)? Since my fianceé is counted twice between us, would the total "dependents" would be 8 so my co-sponsor would have to have 125% of the cost for 8 people? Sorry I'm asking so many questions. I just want to have this figured out now so if I have to move out now or something I'm not rushing and this is confusing.

Sounds like since you claim no one but yourself on your taxes, you would claim just 2, yourself and your fiance.

 

For your co-sponsor, should be 3, her, her husband, your fiance.

Thank you! I actually found a post very similar to mine right after I posted this (Go figure, I looked for a good 20 minutes before posting lol) I put 2 for me and I realized for my co-sponsor it'll be 3.
