How to track your EXP per hour in MapleStory Classic World
"That felt like a good grind" is not a number. Two maps can feel the same and give very different EXP per hour, and a grind that felt rich can lose mesos once you count the potions. Here is how to measure your grind in MapleStory Classic World, by hand or automatically.
EXP per hour, by hand
- Write down your level and the EXP number the game shows when you start.
- Grind for 10 to 15 minutes without going to town.
- Write down the EXP number again.
- EXP per hour = EXP gained ÷ minutes × 60.
Example: you gain 4,000 EXP in 12 minutes. 4,000 ÷ 12 × 60 = 20,000 EXP per hour.
To get the time to level, divide the EXP you still need by your EXP per hour.
It works, but it's easy to get wrong: a town trip, a death or a level up in the middle all throw it off, and you have to stop playing to do the math.
Mesos per hour and Meso Positive
EXP is half the story. A grind also costs potions. To know if it paid:
- Add the mesos you picked up.
- Add what your loot sells for.
- Subtract the potions you drank (yours and your pet's).
One of our own one-hour grinds picked up +7,806 mesos and +463 in loot, then drank 145 potions worth 19,910 mesos. Net: -11,641. It felt like a good hour; it was Meso Negative. Counting this is how you find maps that pay for themselves.
Why some maps pay more
- Monster density beats monster level. A map full of weaker monsters you kill in one hit often gives more EXP per hour than a map of harder ones.
- Short walks. Maps where monsters stay close together waste less time.
- Your hit rate. Missing a lot means slow kills: check your Accuracy against the monster's level.
- Busy channels. Sharing a map halves your kills. Switch channels when you can.
The best maps for your level, with estimated EXP per hour, are in where to train at every level. Each class guide has its own picks.
Track it automatically with MesoLens
MesoLens's grind tracker reads your EXP bar, your mesos and your potions from the screen while you play:
- Live EXP per hour and the time to your next level, from a steady recent pace.
- Starts by itself when EXP starts coming in, and pauses when you go to town, so your numbers stay true.
- Mesos, loot and potions, including the potions your pet drinks, so you see if the hour was Meso Positive or Meso Negative.
- Potions left: how many minutes they last at your pace, with a heads-up before you run out.
- A results card to share on Discord at the end.

Questions
How do I calculate EXP per hour in MapleStory Classic World?
Note your EXP when you start, grind for 10 to 15 minutes, note it again, then divide the EXP you gained by the minutes and multiply by 60. A grind tracker does this live for you.
What does Meso Positive mean?
It means a grind made more mesos than it cost. Count the mesos and loot you picked up, then subtract the potions you used. If the total is above zero, the grind was Meso Positive.
Is there a grind tracker that works in a browser?
Yes. MesoLens in your browser shows your EXP per hour and the time to your next level live when you share your game window, no download needed.
Which map gives the most EXP per hour?
It depends on your level and class. See where to train at every level for the best maps by estimated EXP per hour.
