How to calculate net meso profit per hour

Net mesos per hour = (mesos dropped per hour + what you sell the item drops for) − what you spend on potions, ammo and repairs in that hour.

1. Find mesos per drop. A monster of level L drops floor(2.1 × L) + 3 mesos, ±10%. The table above has it for every 5 levels.
2. Multiply by the drop rate. Monsters drop mesos about 67% of the time, so the average is 0.67 × that number per kill.
3. Multiply by your kills per hour. Count kills over 10 minutes with the EXP tracker and multiply by 6. At 300 kills an hour, a level 30 monster gives about 13,266 mesos.
4. Add item sales. Add what the item drops sell for to an NPC or in the Free Market.
5. Subtract your spending. Take off the potions, arrows or stars and repairs you used that hour. The result is your net mesos per hour.

Questions

How many mesos does a monster drop in MapleStory Classic?

floor(2.1 × monster level) + 3 mesos, ±10%, and it drops about 67% of the time. In a party, the player who loots keeps 20% plus an equal cut of the rest.

Is it better to train alone or in a party for mesos?

A party is worth it when it kills faster than you alone by the factor in the table above (1.74× for a pair). Otherwise you earn less per hour, because the loot is shared.
