I decided to have a look at the BP upgrade of the inventory to see what I could find out for you. Honestly I'd never thought about it too much but it's certainly an interesting question you've posed.

Starting a new EX version I looked into the Inventory number I had and came up with a total of 10 with Item Capacity at 1. At the start of this particular run I had roughly 6,000 BP [or 60 points since it's 1 point per 100 BP ]. Here's my findings so far for the Item Capacity up to level 15.

Level/stat point Item Capacity
1......................................10
2......................................11
3......................................12
4......................................13
5......................................14
6......................................15
7......................................16
8......................................17
9......................................18
10....................................19
11....................................20
12....................................20
13....................................21
14....................................21
15....................................21

At level 15 on the start of Day 3 I had amassed 9016 BP, enough to find out how high the stat modifier for the Item Capacity goes. It caps out at 99 and won't go any higher, but that answers part of your question.

As you can see above we've got an interesting array of numbers. From levels 1-11 the Item Capacity is increased by 1 slot per level/stat point. The stranger part is when we get to level 15 as it breaks the pattern I had thought I'd seen developing. I had figured that from level 11-21 the pattern would follow along the lines of every 2 levels/stat points the Item Capacity would increase by 1. Apparently this isn't so. So I increased the Value by one point and made a spreadsheet out of the whole thing to keep track of my findings. At a point value of 99 Aya has a maximum base inventory of 46 slots. Keeping in mind that there are armor modifies out there I believe the maximum inventory space is either 48 or 50 slots [one guide claims that there is a pocket +4 which I haven't seen personally but for the sake of things I included it anyways as a possibility].

As far as a formula goes I haven't gotten it worked out yet but if you would like the spreadsheet findings just feel free to ask me for them and I'll post a link for them or email them if you'd like.
