Fire Emblem Heroes IV Calculator
Final Stats
The Fire Emblem Heroes IV Calculator is a specialized online tool designed to help players optimize their heroes’ Individual Values (IVs), also known as boons and banes. In Fire Emblem Heroes (FEH), every unit has unique stat variations that significantly affect their performance in battles. Choosing the right asset (boon) and flaw (bane) can make a huge difference in competitive gameplay, arena scoring, and story progression.
This calculator simplifies the entire process by automatically adjusting your hero’s stats based on inputs like HP, Attack, Speed, Defense, Resistance, and selected IV traits. It then provides final adjusted stats and total BST (Base Stat Total) in seconds.
Instead of manually calculating stat changes, players can now instantly determine the best configuration for their heroes, making team building faster, smarter, and more efficient.

Practical Example
Let’s say you are analyzing a hero with the following stats:
- HP: 40
- Attack: 50
- Speed: 30
- Defense: 25
- Resistance: 20
Now you select:
- Asset (Boon): Attack
- Flaw (Bane): Speed
After Calculation:
- HP: 40
- Attack: 53 (+3 boost)
- Speed: 27 (-3 reduction)
- Defense: 25
- Resistance: 20
Total BST:
163
This result helps you understand that boosting Attack while sacrificing Speed may create a powerful offensive unit suitable for aggressive gameplay strategies.
