The perk cost is constantly updated. When you enter the hangar, the cost shown is a snapshot of the cost at the time you entered the hangar. If you spend a minute or two in the hangar, the value is still changing behind the scenes. When you spawn, you will see the actual perk cost in your text buffer.
So, from the time you entered the hangar to the time you spawned, the cost went up from 86 to 94.
