Understanding Fire Emblem Fates Growth Rates
In Fire Emblem Fates (Birthright, Conquest, and Revelation), character progression is determined by a pseudo-random system known as Growth Rates. Unlike some RPGs where stats are fixed, Fire Emblem uses percentages to determine if a specific stat (like Strength or Speed) increases upon leveling up.
How the Formula Works
The total probability of a character gaining a stat point is the sum of two main components:
- Personal Growth Rate: A fixed percentage inherent to the specific character (e.g., Ryoma has high Strength growth, while Elise has high Magic growth).
- Class Growth Rate: A percentage determined by the character's current class (e.g., a Swordmaster grants bonuses to Speed and Skill growths).
The formula is simply: Total Growth % = Personal % + Class %.
For example, if Corrin has a personal HP growth of 45% and is in the Nohr Prince class (15% HP growth), their total chance to gain HP on a level up is 60%.
Using the Aptitude Skill
The skill Aptitude, famously associated with the villager Mozu (and potentially passed down to children), adds a flat +10% to all growth rates. This calculator allows you to toggle this skill to see how it impacts long-term stat averages.
Projecting Stats
This calculator provides an "Expected Value." Since growth is based on probability, you might get lucky or unlucky in a single level up. However, over the course of 10 or 20 levels, your stats will tend to average out. The expected value is calculated as:
Current Stat + ((Total Growth / 100) * Levels Gained)
Use this tool to plan class changes (Reclassing) to patch up a unit's weak stats or maximize their strengths.
