Experience

Experience, EXP or XP, is a value that affects the player's level. It is obtained by completing heists, with certain criteria affecting how much is obtained. For example, in most heists, the player receives extra XP by completing them in stealth, with a few exceptions, such as GMC. Other criteria are the Repeat penalty/bonus, players in custody, and playing alone or with a team (with the latter giving more).

Levelling
Levels are a value increased as the player earns more experience. For each level, the player gains 1 skill point. Every 10 levels, the player gains 1 additional skill point, accumulating a total of 110 skill points at level 100. With infamy, the player can obtain 32 permanent skill points.

Resetting the allocation of one's skill points comes free of charge.

Experience per Level
The experience required per level uses the following formula:

$$1025 \cdot level + level^{1.3}$$.
