What is an FE Fates Calculator?
An fe fates calculator is an essential tool for players of Fire Emblem Fates (Birthright, Conquest, and Revelation) who want to optimize their second-generation units. In this tactical RPG, the children of your main characters inherit stats, growth rates, and skill sets from their parents. Because these mechanics are complex, using an fe fates calculator allows you to predict exactly how a unit like Kana, Selgie, or Siegbert will perform long before they are recruited.
The primary purpose of using an fe fates calculator is to determine the optimal pairings (shipping) to ensure that the child units possess the highest possible growth rates in key areas like Speed or Strength. Without an fe fates calculator, players are often left guessing, which can lead to “bench-warming” units that are outclassed by their parents.
Common misconceptions include the idea that child units only inherit from their mother or that growth rates are purely random. In reality, the fe fates calculator proves that inheritance is a rigorous mathematical formula involving the mother, father, and the child’s unique base values.
FE Fates Calculator Formula and Mathematical Explanation
The math behind an fe fates calculator is built on a specific weighted average. The game calculates growth rates for child units by averaging the growth rates of both parents and the child unit’s own hidden base growth rates.
The standard formula used by this fe fates calculator is:
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Father Growth | The natural growth rate of the male parent. | Percentage (%) | 20% – 75% |
| Mother Growth | The natural growth rate of the female parent. | Percentage (%) | 20% – 75% |
| Child Base | The child’s inherent character-specific growth. | Percentage (%) | 10% – 60% |
| Class Mod | Growth bonus provided by the unit’s current job. | Percentage (%) | 0% – 25% |
Practical Examples (Real-World Use Cases)
Example 1: The Fast Ninja
Suppose you are calculating for Midori (the child unit). If the father (Kaze) has a Speed growth of 65%, the mother (Azura) has a Speed growth of 60%, and Midori’s base Speed growth is 35%. Using the fe fates calculator:
Inherited = (65 + 60 + 35) / 3 = 53.3%. If she is in the Master Ninja class (+20%), her final Speed growth is 73.3%. This confirms she will be incredibly fast.
Example 2: The Tanky Heir
Calculating for Ignatius. Father (Benny) has 65% Defense growth, Mother (Beruka) has 40% Defense growth, and Ignatius has 45% base. fe fates calculator result: (65 + 40 + 45) / 3 = 50%. In the General class (+30%), he reaches an 80% Defense growth rate, making him nearly impenetrable.
How to Use This FE Fates Calculator
- Select Target Stat: Choose which attribute you want to analyze (e.g., Strength, Speed) from the dropdown in the fe fates calculator.
- Input Parent Rates: Enter the growth rates of the parents. You can find these in our fire emblem fates growth rates guide.
- Input Child Base: Enter the child unit’s unique base rate. Reference our fe fates inheritance guide for these hidden numbers.
- Add Class Modifier: Check the current class of the child and add the modifier.
- Analyze Results: The fe fates calculator will automatically update the primary result and the visual chart.
Key Factors That Affect FE Fates Calculator Results
- Parental Synergy: High growth parents produce high growth children. An fe fates calculator helps identify which parents complement each other’s weaknesses.
- Class Choice: Class modifiers are added *after* the inheritance average. Selecting the right class is the most direct way to manipulate the fe fates calculator outcomes.
- Stat Caps: Even if a unit has a 100% growth rate, they cannot exceed their maximum stat caps. Use our fire emblem fates stat caps tool to check limits.
- External Buffs: Skills like “Aptitude” (from Mozu) can drastically increase all growth rates by 10%, a factor that must be included in any deep fe fates calculator analysis.
- Game Version: Certain characters have slightly different bases depending on if you are playing Birthright or Conquest.
- RNG Variance: While the fe fates calculator provides the “average,” actual level-ups are subject to a random number generator.
Frequently Asked Questions (FAQ)
Q: Does the fe fates calculator work for all three routes?
A: Yes, the mathematical logic for inheritance remains consistent across Birthright, Conquest, and Revelation.
Q: How do I calculate the base stats of a child when they join?
A: Base stats use a similar formula but involve the parents’ current stats at the time of recruitment rather than just growth rates.
Q: Why does the fe fates calculator give a different result than my actual unit?
A: Growth rates are probabilities. A 50% growth means a 50% chance to gain +1 stat per level. Your actual unit might be “stat screwed” or “stat blessed” by the RNG.
Q: Can Aptitude be inherited?
A: Yes, Aptitude is a skill that can be passed down, effectively increasing the values you put into the fe fates calculator.
Q: Do secondary classes affect the fe fates calculator?
A: Only the *active* class growth modifier is applied to the unit’s growth at any given time.
Q: Is it better to focus on a child’s strengths or cover their weaknesses?
A: Usually, optimizing strengths is better in Fire Emblem Fates to ensure your units can reliably double-attack or kill in one round.
Q: Does the father always contribute more?
A: No, the formula treats both parents equally in the fe fates calculator calculation.
Q: What is the highest possible growth rate?
A: With the right pairings and Aptitude, some units can exceed 100% in specific stats like HP, meaning they are guaranteed +1 and have a chance for +2 on level up.
