What's the maximum vault limit?

What's the maximum vault limit and if you can please provide each upgrade's time, costs, and results please? Trying to see when I should stop upgrading

It is 90 million I believe. Use the search bar located in the upper right hand corner of your screen. Better yet, I will do it and post the link below.

Here is some of it -

I am sure I have seen a list floating around, all the way to 90, just use the search bar.

It's still 90mil

[Dirty Mind]

the cost is half of the new limit so it will cost $45 mil to upgrade to $90 and each upgrade takes 1 week. each upgrade usually gives a 5-6 mil increase

[S&H Max]

its 5mil increase from 10 mil to 30mil, than its 6mi increase until 90mil

first few are less than 50% but dirty mind is correct it become 50% of the next limit.

they all take 7days after 10mil
