Still inside the `2L+7` formula (2×15+7=37), the last time this cheaper formula applies before the 16-30 range takes over.

Minecraft XP and Levels
Minecraft's experience bar misleads anyone expecting a flat per-level cost: going from level 1 to 2 costs a handful of points, but going from 30 to 31 already costs over 100. The game runs three different formulas depending on the level range, not a single progression.
Still inside the `2L+7` formula (2×15+7=37), the last time this cheaper formula applies before the 16-30 range takes over.
Level 30 still uses `5L-38` (5×30-38=112); level 31 already switches to `9L-158` (9×31-158=121), the steeper formula governing the rest of the game.
The inversion uses a different quadratic formula per point range, not simple division, and returns both the level and the partial progress within it.
Because the cost in points grows with the level, in three bands. Up to 15 the increase is gentle, from 16 to 30 it accelerates, and from 31 on each level costs much more. That is why going from level 49 to 50 takes far more XP than from 9 to 10.
Because the game switches formulas: up to level 15 the cost is `2L+7`, from 16 to 30 it is `5L-38`, and from 31 onward it becomes `9L-158`. Each range change raises the coefficient multiplying the level, accelerating the per-step cost.
1395 XP points from zero. For level 50 it is 5345, and for level 100 it is 30970, a jump that shows how the accumulated cost grows far faster than the level number itself.
Level 21863, the point at which total accumulated XP hits the ceiling of the signed 32-bit integer (2147483647) the game uses to store experience points. Beyond that, the counter simply has nowhere left to grow.
No. XP is the total accumulated points (partly lost on death); level is the number shown on the green bar, derived from that total through a non-linear formula. Two players at the same level can have slightly different XP points within the current level.
That is 1,395 experience points accumulated to reach this level.
