I put a lot of thought into building a wealth score type thing like d20 modern fate & so on use at some point over frustrations from the lack of wbl or similar but could never form anything that worked in a way that fit 5e's shift of power from magic items to base PC & assumption of only starting gear with no feats. Ultimately in the end what I wound up doing is having whoever was employing the party* providing them with a credit line of "You have an idea what you can get approved" without hard numbers. It worked well but pretty much became a one & done stop for gear that might get a second shopping trip just because there isn't really any room in the system math for equipment churn in 5e unless you start changing things elsewhere to force room in.
The downside of doing this is that getting treasure is fun & there is a section in the ad&d dmg on it, but with 5e making that treasure somewhat unusable it avoids the cynicism & frustration that comes with players realizing that.
