Unit Experience Chart

Each unit can have different growth patterns, which sometimes differ by rarity. Growth patterns are listed under individual unit page.

Chart
Most values in the table above have been data mined from the game. Values marked with an asterisk (*) are derived from a formula which perfectly matches known values for every growth pattern except 6.

Formula
The following formula matches the amount of experience needed for a unit to reach the next level, rounded to nearest whole, for all growth patterns except 6:

Growth Factor * 500000 * { [ Current Level / 99 ] ^ ( 5 / 2 ) - [ ( Current Level - 1 ) / 99 ] ^ ( 5 / 2 ) }

Growth factor is the number of the growth pattern, i.e. use 4 for growth pattern 4.

You can approximate the total experience needed to attain level X from level 1 by using the following formula (however, note that due to cumulative rounding after each level, this formula may be off by +/- 5):

Growth Factor * 500000 * [ ( X - 1 ) / 99 ] ^ ( 5 / 2 )

Growth pattern 6 is identical to growth pattern 4 below level 80; for levels 80+, simply add 680 to the experience needed to level up at level 79 for every level above 79. Note that mined data demonstrates that pattern 6 is hard-coded as a distinct pattern from pattern 4 for unknown reasons.
