Calculators

4 planning tools built on the Classic World datamine. They answer "how long is this actually going to take" so you can decide whether it's worth it before sinking the evening into it.

Grind planner

EXP calculator

Pick a mob, enter your kill rate, get EXP/hour and time to your next level (or to a target level).

Lv 1-30 uses canonical traditional MapleStory EXP values. Above that the curve is extrapolated pending in-game verification.

Loot planner

Drop rate estimator

Datamined drop tables across 80 mobs and 756 unique items, plus the probability math for how many kills it'll really take.

Rates are traditional MapleStory community estimates - Nexon doesn't publish Classic World drop rates. Treat them as a planning baseline.

Income planner

Meso income estimator

Meso-per-hour from your grind rate, minus potion drain, plus hours-to-goal for whatever you're saving up for.

You supply the meso-per-kill from your own sampling; the tool does the projection, not the observation.

Theorycrafting

Damage estimator

Min/max/average damage for a weapon and stat spread, with mastery scaling and target defense reduction.

Built on the traditional MapleStory damage formula. If Classic World retuned any multiplier, this follows the old math until we can verify.
