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 new abilities, items, and other achievements. You can earn XP (experience) by training skills, completing quests, doing activities such as Penguin Hide and Seek, Mage Training Arena, and other Minigames and activities. The minimum XP needed to max all skills is 374,968,717 (510,752,596 with 120 Dungeoneering and Invention) (299,793,508 xp for pure F2P).
Gaining experienceEditExperience in a skill is obtained by performing a task related to that skill. Experience can also be gained by completing a daily challenge, completing a quest, or by playing a minigame or miniquest.
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, certain clothing, 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 shared through the Assist System (namely gathering and combat skills, such as Attack and Mining).
Players can continue receiving experience after level 99 in a skill, up to a maximum of 200 million experience. Once a player reaches this limit, they can continue using the skill, but receive no additional experience. The maximum total experience possible is 5 billion 400 million (5,400,000,000) when a player has 200 million experience in all 27 skills.
Until the Skills Interface update (on 12 November 2007), players with a level 99 skill could view the experience it would take them to earn level 100. However, even when "level 100" was "reached", the actual level remained at 99, and it would not show the experience required to achieve level 101.
The experience gain rates one may obtain varies very much between skills. For example, with 99 Agility it is difficult to get much over 70k Agility experience per hour without brawling gloves, while making summoning pouches can give over 800k Summoning experience per hour.
It is possible to set an individual level target for each level. You can set a level target or a target experience for each level individually. Setting two different targets for two different skills will not affect either of the levels.
Relationship with LevelEdit
The amount of experience between levels rises by a factor , or 10.4%, each level. This exponential growth means that level 99 requires 13 million xp and level 120 requries 104 million xp.
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. But higher level activities award more experience than lower level ones, so going from level 98 to 99 is much faster than going from level 1 to 75.
Total experience doubles every 7 levels (after level 20 or so), triples every 11 levels, quadruples every 14 levels, and increases almost 10-fold every 23 levels. 200,000,000 experience in a skill would put the level between 126 and 127.
The minimum total experience needed for a given level, L, is given by:
- Note: means the greatest integer less than or equal to . This is also known as the 'floor' function.
This equation can be rewritten as:
The function is the error made by not rounding each term of the sum down. The rounding error is at most 1 for each term, so a good estimate is
where a is some number between 0 and 1. Using gives an error less than 1 xp for any level between 1 and 120. Omitting the term gives an error of at most 13 xp. 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 xp is negligible), doubling your experience after reaching a given level will result in rising seven levels, since .

- On 31 August 2012, 350,000 xp was given to players who had been a member all month.
- On 30 September 2012, 700,000 xp was given to players who had been a member all month, and all the previous month. The combined award of 1.05 million XP would get a new character to around level 41 in all skills, but is not enough to go from level 98 to 99 in one skill.
- On 15 December to 16 December 2012, double Dungeoneering experience was awarded during one of the Winter Weekends.
- Experience gained on member's skills while F2P is capped at 388 (Level 5).
- If levels were capped at the point where 2,147,483,647 experience was reached in that skill, you could get up to level 150, needing ~2,034 million experience. The current maximum experience per skill (200,000,000) would allow a maximum skill level of 126.
- Experience is capped at 200,000,000 because experience is handled with an invisible tenths place, which means the real experience would look like 200,000,000.0 and is stored as 2,000,000,000 (2 billion). Since the max a 32 Bit integer can hold is 2.14 billion, it was cleaner to round it down to 2 billion (shown as 200m after the invisible decimal place) for the cap. However if an unsigned integer were used the amount could double.
- The equation for the maximum integer size in RuneScape is 2³¹ - 1, which equals 2,147,483,647. Because Runescape uses 32 Bit (java standard integer) integers at the moment, if RuneScape was to switch to 64 bit integers (java long) the maximum value would be 9,223,372,036,854,775,807 (9.2 quintillion on the short scale, or 9.2 trillion on the long scale). However, since Jagex handles experience with invisible tenths, the total experience would actually be 922,337,203,685,477,580, having this much experience would be equivalent to a level of 351. Having every skill at level 351 would result in a combat level of 447 on free-to-play worlds, 491 on member's worlds, and a total level of 9126.
- The total amount of experience in any given skill approximately doubles every seven levels (This doesn't remain accurate for skills below level 20, since starting with 0 experience takes a while to adjust).
- The amount of experience between levels 98 and 99 is roughly the same as the amount between levels 1 and 75, while the experience between levels 119 and 120 is equivalent to getting levels 1 to 96.
