What the hell is Effective Hit Points

Greetings my fellow pod pilots and blog readers!

A lot of new (and some experienced) players ask, "What is EHP?"  The short answer...
Effective Hit Points (EHP) It is a estimation on the amount of damage your ship can take, based upon its lowest resistances.

EHP = Hitpoints / (1 - Fractional Resistance)
***note***Fractional Resistance is the resistance percentage divided by 100.

To determine your total EHP you must determine the EHP for each tank type. (Shield, Armor, & Hull)
So let us look at the basic OMEN hull, with no character skills, as an example:

SHIELD
Shield Capacity = 1,173
Shield Resists = EM 0% Thermic 50% Kinetic 40% Explosive 20%
Shield EHP = 1,173 / (1-(0/100)) = 1,173

ARMOR
Armor Capacity = 1,563
Armor Resists = EM 50% Thermic 20% Kinetic 25% Explosive 35%
Armor EHP = 1,563 / (1-(20/100)) = 1953.75

HULL
Hull Capacity = 1,563
Hull Resists = EM 0% Thermic 0% Kinetic 0% Explosive 0%
Hull EHP = 1,563 / (1-(0/100)) = 1,563

TOTAL EHP = 4,6690

EHP is why a lot of ship setups use a Damage Control unit in a low slot.  As it gives a bonus resists to all three tank types.


I'd like to thank my fellow corp mate, McCreary075 for inspiring this post & the math that goes with it.

Until next time,
