Costs for successive building in each tier follow a geometric progression, so each building costs a constant factor more than the previous building of that tier.
Cost Formula for the x-th building in a tier: (B * M ^ (x - 1)), where B is the cost of first building of that tier and M is the building cost multiplier.
Building Cost Multiplier
The base value of the building cost multiplier is 1.15, but can be reduced by upgrades that give a flat cost reduction (e.g. Gobline) and also depends on your Ascension.
Building Cost Formula in A0 and A4: (1 + 0.15 - C), where C is the sum of your flat cost reduction upgrades.
Building Cost Formula in A1 - A3: (1 + (0.15 - C) / (5 * A)), where C is the sum of your flat cost reduction upgrades and A is your Ascension.
