Killing monsters and fulfilling certain tasks will grant players experience (also known as xp, exp) which they can accumulate to increase their levels in professions. Players will start a profession with zero experience, and are able to level their professions to level 500.
The following tables shows the relationship between the profession level, the experience required for that level, and the experience difference from the previous level:

Experience figures
The following figures show the required experience per level and cumulative experience:
Since the experience scales quite significantly, here the figures are repeated with a logarithmic exp-axis:
Required experience amount breakpoints
Based on the above table, we can notice a few breakpoints in the experience formula:
Novice
Levels 0-6 : every level requires around 2,95% more experience than the previous one;
Levels 7-12: every level still requires 2,95% more experience, but the required experience is also doubled;
Levels 13-20: again, every level requires 2,95% more experience, but it is once again doubled.
For example, going from level 13 to level 14 requires slightly more than 4x the experience required from level 4 to level 5.
Apprentice to expert
Levels 21-200: the required experience, per level, has been quintupled (explaining why you suddenly feel like you hit a wall once you are at skill level 20), and every new level from 21 to 200 requires 1,94% more experience than the previous one.
Expert to ultimate
Levels 201-500: the required experience per level is now quadrupled, then every new level requires around 0,60% more experience than the previous one.
Conclusions
Since the experience gain per action grows at a similar rate than experience needed (the percentage increase), but with no breakpoints, one can assume that the amount of actions required to level up from, let's say, 21 to 22, is the same than the one required from 198 to 199.
Levels 0-20 are certainly made easier for the sake of allowing players to explore new professions quickly, and can be seen as the introduction to a skill and its game loop.
Levels 21-200 are intended to be regular levels, requiring some dedication from the player, and setting them up for the final xp wall. Most of the game's content for a particular skill is unlocked prior to level 200.
Finally, levels 201+ encourages the player to identify and specialise in a select few skills that they would like to pursue achievements in, such as leaderboards and the ultimate cape, or for their own enjoyment.
Impact of knowledge conversion into experience
Between levels 20-200: converting one knowledge point into experience grants 25% of a level.
However, between levels 201-500, each KP grants 6,25% of a level. Given that levels 200+ take four times more actions, this means that the experience each KP gives retains their numerical scaling from 20-200, but are 4 times less effective due to the increased experience per level. This encourages active training and prevents KP being used to significantly skip over endgame content..
Experience penalties
The game imposes several experience penalties for overlevelling certain activities, as detailed below.
Easy battle penalty
In combat and activities which involve combat, such as Crime Dens, defeating a monster that is 11 or more levels below the player's combat level will incur an experience penalty, known as the easy battle penalty, on the experience earned from completing the activity. This penalty increases with increasing level difference.
Although the game has a display for this during combat initiation, this indicator is not always accurate. The experience awarded for fighting a monster of a certain level below the player's combat level can be more accurately estimated with the following formula. This is also reflected when looking at monster information cards, and is calculated using the player's current combat profession compared to the monster's combat level, even if the card of the monster being viewed is from another episode.
rounded down to the nearest integer.
where
Currrent XP
XP obtained for killing the monster at your current level
Base XP
Base XP awarded by the monster without penalty
C
The combat profession level of the player, depending on the episode they are currently physically located in. For example, if a player looks at a monster card of a monster from Mines of Mantuban while physically standing in Crenopoplis, this would be their Watchperson level, NOT their Minefighter level.
M
The combat level of the target monster
From this we can deduce that the XP penalty itself is given by the following
where
The theoretical maximum penalty, applied when a level 500 player fights a level 0 monster, according to this formula, is 99.89%. However, due to the low base experience (205) of a level 0 monster, this value (0.23) is rounded up to 1xp, which is the minimum xp a player can earn after defeating a monster. This increases the actual penalty to 99.5%, despite its formulaic value being much lower.
Currently the smallest observable penalty ingame occurs at a combat level difference of +11, giving a penalty of 1.38% (displayed as 2% in-game), while the greatest observable penalty, currently still subject to more testing, occurs when comparing a level 500 Watchperson with a level 39 Eyeless Zombie, at a level difference of +461, for which the player will obtain 1xp (rounded down from 1.46) out of the monster's 758 base experience, resulting in a 99.87% penalty correct to two decimal places (displayed as 99% in-game).
Passive activity penalty
The player will incur an experience penalty for doing passive activities below the highest tier available to them, which is summarised below. Decimal experience values after calculation are rounded down. This penalty is not combat-specific, and is not explicitly displayed anywhere in-game.
This experience penalty is applied immediately upon reaching the level of the next passive activity, and is applied even without unlocking the new activity.
