Growth rates (Japanese: 成長率 growth rate), known as maturity in the GBA games, are a set of hidden stats associated with individual playable units which dictate the probability of a unit's stats increasing.
For each character stat that can increase during a Level Up, such as Strength or Skill, there is a growth rate associated with it. Growth rates are the percentage chance of the unit gaining 1 point in a particular stat during a Level Up, with the random number generator used to determine whether a stat increases or not. For example, a growth rate of 40% yields on average 2 stat up per 5 Level Ups.
In rare cases, growth rates may exceed 100%. In these case, 100% is subtracted off the growth rate and becomes a guaranteed +1 during a Level Up, with the remaining growth rate allowing for a chance to gain another +1 (effectively a +2). Since the maximum growth rate is typically 255% (due to the games' programming), the maximum stat increase during a Level Up is +3 (which is possible with Karel in The Binding Blade, as he has a HP growth of 210%).
Growth rates are usually hidden from the player, although some guidebooks may list them or provide growth rankings (such as "A" for growths of 100% to 80%). In most cases, they are obtained by hacking the games. For this reason, information on growth rates in Awakening is limited as its console had not been cracked to enable discovering this information at the time of its release; no growth rate information is currently available for any SpotPass or DLC bonus unit (with the exception of the DLC Marth, and even the known information for this unit has been called into question).
Generic enemy units use a different set of growth rates, known as class growth rates. Enemies do not Level Up in the traditional manner, so instead they are auto-levelled upon being generated at the beginning of each chapter, or when they arrive as reinforcements). This is why enemies will usually have slightly varying stats each time you replay any given chapter. Class growth rates are also used to determine Hard Mode bonuses and, in Shadow Dragon onward, contribute to the growths of playable characters through implementation in the reclassing system.
In Path of Radiance, the Fixed Mode is upon completing the game for the first time. This is an alternate method of unit growth which revolves around the accumation of growth points from fighting enemies with certain weapons to dictate a unit's growths. The other option is Random Mode, which is the standard growth rate system used in the rest of the series and in the first playthrough of Path of Radiance.
List of growth rates by game
While the majority of games share a similar set of growth rates, as they do stats, some games offer minor variations on the existing growth rates by featuring unique growth rates which don't exist in most other games, or in the case of earlier installments in the series, the stats in question did not exist as of yet.
|Stat growth rate||Exists in:||Notes|
|Strength||In Gaiden, The Binding Blade, Fire Emblem and The Sacred Stones, Strength and Magic are technically the same value and are presented as one or the other depending on the individual unit's class and weapon ranks.|
|Magic||In Gaiden, The Binding Blade, Fire Emblem and The Sacred Stones, Strength and Magic are technically the same value and are presented as one or the other depending on the individual unit's class and weapon ranks.|
|Weapon level||The weapon level stat was replaced by the weapon rank system from Genealogy of the Holy War onward.|
|Resistance||While the stat exists in Fire Emblem: Shadow Dragon and the Blade of Light and Fire Emblem Gaiden it has no governing growth rate associated with it. |
Resistance was absent in Thracia 776.
|Constitution||While constitution/build is present in multiple games, Thracia 776 is the only game in which it has a growth rate, and thus a chance to increase by level.|
|Movement||While movement is present in all games, Thracia 776 is the only game in which it has a growth rate, and thus a chance to increase by level.|
|A means that the stat has a growth rate in that game, while a indicates the contrary.|
Items and skills affecting growth rates
Throughout the series, there are a number of items and skills which can be used to increase the growth rates of a single unit either temporarily or permanently. Most commonly, these come in the form of items which provide temporary boosts while held in a unit's inventory, and accordingly no longer apply to that unit when removed from their inventory. There are also instances of equippable skills which serve the same function and consumable items which give a single permanent increase to all growth rates.

- While the vast majority of the series hides character growth rates, Fire Emblem Gaiden's manual has accurate growth rates for a handful of the earlygame cast, including growth rates for Alm and Celica.
