The formula for the amount of experience to complete a level is as follows:
Total XP to complete a level = L3 * C * R * H
Where:
C = Class Multiplier
R = Race Multiplier
H = Hell Multiplier (based on level)

The formula for the amount of XP earned for soloing a blue or higher mob is as follows:
XP = L2 * C
Where:
L = Level of mob being soloed.
(If the mob is green, the xp earned will be 50%, 25% or 0% of the stated value.)
C = A number that seems to vary.
In most outdoor zones it is 75, in most dungeons it is 80, in some newbie zones it is 100.
The table to the right is calculated assuming a value of 75.
Note - The maximum XP that can be earned from a single mob is approximately 11% of the XP required to complete the level.
