Defense Calculator
Calculate effective HP and damage reduction based on HP and defense values
Shared buffs applied to all ship configurations
Effective HP Explanation
Effective HP represents how much raw damage your ship can take before being destroyed, taking damage reduction into account.
The formula for calculating Effective HP is:
Effective HP = HP / (1 - (Damage Reduction / 100))
Defense buffs multiply the base defense stat before calculating damage reduction. Incoming damage buffs (e.g. -30% Incoming Direct Damage) further adjust effective HP.
Security does not affect Effective HP directly — it determines how well your ship resists debuffs from hackers. Higher security reduces the chance that hacking attempts succeed.
Damage Reduction Curve
Damage reduction follows a curve where higher defense values have diminishing returns. The interactive chart below shows how damage reduction increases with defense values from 0 to 26,000, and marks the position of your ship configurations.
