To use the Base HP Calculator, enter the level of each building in the column next to the building name. If a building has not been built or has been scrapped, enter a zero for its level. The calculator will update the HP for that building based on its level and calculate each building percentage of the entire base's HP. Default settings are for a fully built out base. Cell protection is used to prevent incorrect levels from being entered.

To determine Bubble / Star thresholds when being attacked, enter a "Y" by each building that has been destroyed. The calculator will determine the % HP destroyed and display a message if the bubble or star thresholds have been crossed.

Thanks to PriceIsWrong from Battle Vortex for suggesting this calculator, and xnih from BP Info for giving the base hitpoint data.

Quick Update

I added the Conquest Yard and the Advanced Lab level 13.  Thanks to the "unknown" commenter who pointed it out.

Note that the health on some of this new stuff is pretty much a guess based on patterns of previous levels.  However, the errors shouldn't be too large since the WH, turrets, and OP are really what drives your bubble pad.


  1. Hi, i have equipped the draconian seawall to lvl 1 portal, in game it now shows its health/armour at 5,714,290 , does the bubble pad need adjusting for this increase, or does it still use the base 2.5mill?


  2. Generally, things you equip, like armor on your turrets, do not count towards bubble calculations. I'm not totally sure that the traps (like the seawall) work the same, but for now I assume they will.

    You could test this if you have someone shoot at a trap and then look to see if the damage bar moves while they do that. It should only start moving after the trap falls.

  3. You've put a lot of efforts to that calculator. And it looks really impressive, wanna like to try it out!
