Cash vs Robux prices
The cash price goes from $150 for the Border Tower to $150 billion for the Air Fortress. That is 1 billion times more. The Robux price only goes from 4 to 2,799, which is about 700 times more.
So Robux prices stay small while cash prices explode. The Bio Rocket is the only building here with no Robux price at all.
The biggest price jumps
The biggest jump is between the Artillery Depot at $250 million and the Rocket Bunker at $5 billion. That is 20 times the price, and it is where Mythic ends and Secret starts.
Expect a long save there. Every building after the Artillery Depot costs billions.
