Total EXP needed to reach level 200 from level 1 is 30,950,360,817. In the Time Temple and Pink Bean Boss release patch, EXP needed for Level 10~30 was cut by 33% and Level 31~199 was cut by 20%.
The EXP tables have undergone several revisions over the years, as Nexon has attempted to speed up the leveling process overall and for different groups of levels. However, Mega Burning is assumed up to level 130 only, so the EXP savings will be greater in GMS as Mega Burning lasts till level 150. You can refer to a graphical version here, but a text version is also available below.
For example, to calculate level 3's Total EXP earned so far (49), add both level 2's Total EXP earned so far (15) and EXP to next level (34) values.
To calculate the Total EXP earned so far for a level, add the Total EXP earned so far value of the previous level and the EXP to level value of the previous level. EXP to next level specifies how much more EXP is required to reach the next level.
