What progression formulas does this calculator support?

Three formulas: Linear (each level costs the same flat XP, e.g. 1000 XP per level), Polynomial/Quadratic (XP per level = base × level^exponent, used by many JRPGs and D&D 5e), and Exponential (XP per level = base × multiplier^level, producing steep late-game curves common in idle and MMO games).

Which formula should I use for my game?

Linear works for simple or custom systems. Polynomial (quadratic, exponent = 2) matches many popular RPGs including Runescape and classic JRPGs. Exponential fits games with very steep late-game XP walls, such as idle games or some MMOs. Try each and compare the level table to your game's actual values.

How do I find the right base XP and scaling values?

Look up two known XP thresholds in your game (e.g. XP to reach level 2 and level 10), then adjust the base and scaling inputs until the calculator's table matches. Most wikis or game files list exact XP tables you can cross-reference.

What does the XP progress bar show?

The bar shows how far into your current level you are. 0% means you just leveled up; 100% means you have exactly enough XP to advance to the next level. The remaining XP counter shows the exact shortfall.

Can I use this for non-video-game systems like D&D?

Yes. D&D 5e uses a fixed XP-per-level table, which is closest to the polynomial formula. Set exponent = 2 and adjust base XP until level thresholds match the Player's Handbook values (e.g. 300 XP to reach level 2, 900 for level 3, and 2,700 for level 4).

Summary

The XP to Level Calculator converts raw experience points into character levels using three common RPG progression formulas: linear (fixed XP per level), polynomial (quadratic growth used in many tabletop and video RPGs), and exponential (steep late-game curves). Enter your total XP, choose a formula and scaling factor, and the tool instantly displays your current level, XP progress within the current level, and the exact XP needed to reach the next milestone.
