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, 2700 for level 3).
