I'm currently at 61 levels and my cost of building a new level is over 520K credits.
Is there a fixed amount the cost goes up by or is it a progression? Admittedly I haven't been paying enough attention. Sometimes it seems to go up a few thousand, others 10s of thousands per level.
I'm asking because I may want to complete all the imperial levels, and can't decide if it's worth doing earlier in the game because of cost. Or, is it worth building levels that generate more income due and will finance the construction of those levels later.

The values for floors don't start according to a formula until you get to floor 12, which costs 12,150. Once you reach that floor, the formula is:
150 * (Floor # - 3) * (Floor # - 3)
So, for floor 12 (which is actually the 10th floor you build) , you'd come up with: 150 * 9 * 9 = 12,150
For floor 83, you'd come up with 150 * 80 * 80 = 960,000
I've verified this formula works for all floors from 12 to 83. Floors 3 through 11 appear to be random in how costs are calculated.
Also, random factoid, the amount of the increase increases by 300 for each level (after 12). So going from 12 (12,150) to 13 (15,000) is a 2,850 increase. Going from 13 (15,000) to 14 (18,150) is a 3,150 increase, which is the 2,850 (from 12->13) + 300.
Going from 14 (18,150) to 15 (21,600) increases by 3,150 + 300 for a total of 3,450.
I'm sure that's just a function of math in the original formula, but I thought it was a neat pattern.
As requested, here is a graph of the costs:
Here are the values for each floor and how long it takes to build:
