Welcome to the definitive **maplestory cubing calculator** for determining the expected cost (in Mesos) to reach your perfect potential line. Cubing is highly probabilistic, but with this tool, you can estimate the financial outlay required to hit that coveted 3-line Attack% or Boss Damage unique stat. Input your target probability and cube cost to begin!

Maplestory Cubing Calculator Formula
The calculation is based on the Expected Value (E) of a Bernoulli trial, where success is rolling the desired stat line, and failure is anything else. The total cost is derived from this expected number of trials.
$$ \text{Expected Cubes (E)} = \frac{1}{\text{P}_{\text{Target}} \times \text{M}} $$ $$ \text{Total Mesos Cost} = \text{E} \times \text{C} $$Where:
- $\text{E}$: Expected Number of Cubes
- $\text{P}_{\text{Target}}$: User-inputted Probability of rolling the desired stat line (e.g., 0.001)
- $\text{M}$: Success Rate Modifier (e.g., 1.05 for Black Cube)
- $\text{C}$: Cost per Cube (in Mesos)
Variables Explained
- Item Potential Tier: Contextual input (e.g., Unique or Legendary). Cubing for high-tier stats is typically only done at Legendary.
- Target Stat Probability ($\text{P}_{\text{Target}}$): The single-cube probability of achieving your specific desired outcome (e.g., 30% Boss Damage line, or 2 lines of 12% STAT). This value is sourced from community data or in-game probability tables.
- Cost per Cube ($\text{C}$): The average market price of the cube you are using (e.g., Red Cube, Black Cube) on your server’s Auction House, measured in Mesos.
- Success Rate Modifier ($\text{M}$): Accounts for cube types that affect probability, such as Black Cubes which have a slightly higher chance of retaining or increasing tier/stat value, which can be interpreted as a modifier on success chance.

What is maplestory cubing calculator?
A Maplestory cubing calculator is a tool based on probability and expected value theory used to estimate the cost of obtaining a desirable Potential line on equipment. Since the Potential system involves randomized outcomes governed by fixed probability tables, calculating the expected value allows players to budget their Mesos or NX more effectively.
The “Expected Value” is the average number of cubes (or the average cost) you should statistically expect to spend to achieve the outcome. It’s a critical financial metric for players serious about optimizing their Mesos spending and progression in the game, preventing ‘whaling’ with no defined spending limit.
It is important to remember that cubing is a high-variance activity. While the calculator gives an average, you may hit the desired stat significantly sooner or, conversely, spend several times the expected amount. This calculator provides the statistical mean for long-term cubing.
How to Calculate Expected Cubing Cost (Example)
- Determine the Target Probability ($\text{P}_{\text{Target}}$): Identify the specific potential line you want (e.g., 2 lines of 9% LUK on a Legendary accessory). Find the combined statistical probability for that roll. Assume it is $0.0005$ (or 0.05%).
- Find the Cube Cost ($\text{C}$): Check the Auction House for the current price of a Red Cube. Assume it is $\text{14,000,000}$ Mesos.
- Apply the Modifier ($\text{M}$): Since you are using a Red Cube, the modifier is $\text{M}=1.0$.
- Calculate Expected Cubes ($\text{E}$): Use the formula: $\text{E} = \frac{1}{\text{P}_{\text{Target}} \times \text{M}} = \frac{1}{0.0005 \times 1.0} = 2000$. The expected number of cubes is 2,000.
- Calculate Total Cost: Multiply the expected cubes by the cost per cube: $\text{Total Cost} = 2000 \times 14,000,000 = 28,000,000,000$.
- Review: The expected cost to hit this line is 28 Billion Mesos. You can then adjust your strategy or cube type based on this figure.
Frequently Asked Questions (FAQ)
- What is the difference between Red and Black Cubes?
Red Cubes are cheaper and lock the potential tier, while Black Cubes are more expensive and offer a chance to tier up the potential and allow you to choose which potential line to keep (current or new). - How accurate is the maplestory cubing calculator?
The calculator is mathematically exact based on the input probability ($\text{P}_{\text{Target}}$). Its real-world accuracy depends entirely on the accuracy of the probability value you input, as Maplestory’s official rates are sometimes debated or updated. - Why is the expected cost so high for good lines?
High-tier potentials, like 30% STAT or 40% Boss Damage, are often compounded probabilities (e.g., rolling two specific lines simultaneously), making their individual chances extremely low, thus driving the expected cost exponentially higher. - Does the potential on the item affect the cubing chance?
Yes. Official probability tables show different rates for specific stats depending on the equipment type (weapon, secondary, emblem vs. armor/accessory). Ensure your $\text{P}_{\text{Target}}$ reflects the item you are cubing.
