The CSGO Case Calculator is a tool designed for players of the popular video game “Counter-Strike: Global Offensive” (CSGO). This calculator helps players determine the expected value of opening various in-game item cases. By calculating potential profits or losses, players can make more informed decisions about whether to open a case or purchase items directly from the marketplace.

## What is the CSGO Case Calculator?

The CSGO Case Calculator computes the expected value from opening a case by considering both the costs of the case and the key, along with the probabilities of obtaining items of different market values. This tool is particularly useful for players looking to understand the financial aspect of case openings and manage their in-game investments wisely.

## How Does the CSGO Case Calculator Work?

The workings of the calculator are based on a simple yet effective formula that incorporates several key inputs:

**Cost of Case:**The purchase price of the case.**Cost of Key:**The price of the key needed to open the case.**Item Drop Rates:**The chance of each item category being dropped.**Market Value of Items:**The average selling price of items in each category on the game’s marketplace.

## Formula:

The expected value (EV) is calculated using the following formula: Expected Value=(∑(Drop Rate of Item𝑖×Market Value of Item𝑖))−(Cost of Case+Cost of Key)Expected Value=(∑(Drop Rate of Item*i*×Market Value of Item*i*))−(Cost of Case+Cost of Key)

## Step-by-Step Calculation:

**Calculate the Expected Value of Each Item Category:**- Multiply the drop rate by the market value for each category.

**Sum the Values:**- Add all the expected values to get a total.

**Subtract the Costs:**- Deduct the combined cost of the case and key from the total expected value to find the net expected value.

## Example Calculation

Here is a practical example using hypothetical data:

**Cost of Case:**$0.50**Cost of Key:**$2.50**Drop Rates and Market Values:**- Mil-Spec: 79.92% chance, $0.15 market value
- Restricted: 15.98% chance, $0.75 market value
- Classified: 3.2% chance, $2.50 market value
- Covert: 0.64% chance, $10.00 market value
- Knife: 0.26% chance, $100.00 market value

Using the formula, calculate the expected value for each category and sum them up. Then, subtract the total costs to find the net expected value.

## Calculation:

**Expected Value Calculation:**- Mil-Spec: 79.92%×$0.15=$0.1198879.92%×$0.15=$0.11988
- Restricted: 15.98%×$0.75=$0.1198515.98%×$0.75=$0.11985
- Classified: 3.2%×$2.50=$0.083.2%×$2.50=$0.08
- Covert: 0.64%×$10.00=$0.0640.64%×$10.00=$0.064
- Knife: 0.26%×$100.00=$0.260.26%×$100.00=$0.26

**Total Expected Value:**$0.64473**Net Expected Value:**$0.64473 – $3.00 = -$2.35527

## Data Table

Item Category | Drop Rate (%) | Market Value ($) | Expected Value ($) |
---|---|---|---|

Mil-Spec | 79.92 | 0.15 | 0.11988 |

Restricted | 15.98 | 0.75 | 0.11985 |

Classified | 3.2 | 2.50 | 0.08 |

Covert | 0.64 | 10.00 | 0.064 |

Knife | 0.26 | 100.00 | 0.26 |

## Conclusion

The CSGO Case Calculator serves as a crucial tool for players who want to approach the game economically. By calculating the expected value of case openings, players can avoid unnecessary losses and optimize their in-game expenditures. Whether you are a casual player or a serious trader in the CSGO market, this calculator offers a clear insight into the often risky business of case openings.
