Experience, commonly abbreviated as XP or exp, is a measure of progress in a certain skill. It is generally obtained by performing tasks related to that skill. After gaining a certain amount of experience, players will advance to the next level in that skill, which can result in unlocking new abilities, items, and other rewards. Experience can be earned by directly training skills, completing quests, and participating in activities, such as events, minigames, and Distractions and Diversions.
The maximum level for most skills is level 99 which is achieved at 13,034,431 experience. Certain skills feature additional content up to level 120 at 104,273,167 experience. Virtual levelling can be enabled to visually display levels above 99 for all skills. Invention, an elite skill, follows a different experience curve.
The maximum experience that can be gained in a skill is 200 million experience. Once a player reaches this limit, they can continue using the skill but additional experience is not recorded.
For skills where failure is a possibility, experience is usually only granted on completion of a successful action. For example, if a player cooks a lobster rather than burning it, they will gain a minimum of 120 Cooking experience. Experience gains can be increased in a variety of ways, including bonus experience, skilling outfits, and the effect of bonfires on Cooking and Firemaking.
Players who help others using the Assist System can earn a maximum of 30,000 total experience every 24 hours, although the experience may be shared among many skills. Some skills cannot be assisted, namely combat and gathering skills, such as Attack and Mining.
The experience gain rates a player may obtain varies very much between skills. For example, most Agility training methods give under 75,000 experience per hour, while making pouches can give over 800,000 Summoning experience per hour.
It is possible to set an individual level target for each level. A level target can be set or a target experience for each level can be set individually. Setting two different targets for two different skills will not affect either of the levels.
The amount of experience between levels rises by a factor , or 10.4%, each level. In other words, the total experience required for a level approximately doubles every 7 levels (disregarding the first 20 levels), triples every 11 levels, quadruples every 14 levels, and increases almost ten-fold every 23 levels. This geometric growth means that level 99 requires about 13 million experience and level 120 requires about 104 million experience. 200 million experience in a skill would put the level between 126 and 127.
The increasing experience needed to get from one level to another has some surprising consequences; getting from level 98 to 99 requires approximately the same experience as from level 1 to level 75, while the experience between levels 119 and 120 is roughly equivalent to getting levels 1 to 96. Higher level activities award more experience than lower level ones, so going from level 98 to 99 is typically much quicker than going from level 1 to 75.
The error term is the made by not rounding each term of the sum down. The rounding error is at most 1 for each term of the sum, so a good estimate is , where is some number between 0 and 1. Using gives an error less than 1 experience for any level between 1 and 120. Omitting the term gives an error of at most 13 experience. Omitting the term gives an error of at most 2% (peaking at around level 16).
The middle term always dominates. The total experience between consecutive levels is therefore
The experience to next level increases by 10.4% from the previous experience to next level.
For all levels above about 20 (i.e. for levels where 83 experience is negligible), doubling experience after reaching a given level will result in rising seven levels, since .

the main method of gaining experience is practice in the skill (including combat) substantial amounts of experience are available from other sources.
It's unknown at which steps experience is rounded. The wiki calculator currently assumes no rounding occurs until the end and then rounds to the first digit after the decimal.
Total experience = Item experience * Other experience * Bonus experience * Item gather rate
It is currently unknown if boosts in this category are additive or multiplicative.
The majority of buffs in the game fall under this category and are additive with each other.
The only buff that goes in this category is bonus experience. It multiplies everything else by 1.5x.
