What This Means
Understanding CS2 Case Opening Economics
Case opening in CS2 is fundamentally a negative expected value proposition. This means that, on average, you will lose money. However, understanding the exact economics helps you make informed decisions about whether the entertainment value justifies the cost.
This calculator uses the expected value formula from probability theory to calculate what you can expect to receive, on average, when opening cases. According to economic research on loot box spending patterns, most players underestimate their actual losses.
How Break-Even Calculations Work
The expected value (EV) of a case opening is calculated by multiplying each possible outcome's value by its probability, then summing all results:
Expected Value Formula
EV = Σ (Probability × Value) EV = (0.0026 × Knife) + (0.0064 × Covert) + (0.032 × Classified) + (0.1598 × Restricted) + (0.7992 × Mil-Spec) Your profit/loss per case = Expected Value - Cost per Opening
Why Break-Even Is Usually Impossible
For most CS2 cases, the expected value is significantly lower than the cost to open them. This isn't a bug - it's by design. Valve builds in a "house edge" similar to casinos. Here's why:
- Mil-Spec items dominate: With 79.92% of drops being blue-tier items worth $0.03-$0.30, the weighted average is heavily skewed toward low values
- Rare items are truly rare: Knives (0.26%) and Coverts (0.64%) are too infrequent to offset consistent Mil-Spec losses
- Key prices are fixed: At $2.49, the key alone often exceeds the expected return
The "Theoretical" Break-Even
Our calculator shows "theoretical" break-even because it would require impossible luck to actually achieve. If a case has -70% expected ROI, you'd need extraordinary knife luck to overcome the statistical deficit. Most players never break even over their lifetime of case opening.
StatTrak Premium Explained
StatTrak items track kills and are worth more than their non-StatTrak counterparts. When enabled, our calculator adds approximately 20% to the expected value, accounting for:
- 10% chance of any item being StatTrak
- StatTrak items averaging roughly double the price of regular items
- Combined effect: approximately 10% × 100% premium = 10% overall boost (we use 20% as StatTrak premiums often exceed 100%)
For a more detailed breakdown of StatTrak mechanics, see our StatTrak Complete Guide.
Case Value Variations
Different cases have dramatically different expected values based on their contents:
- Cases with popular knives/gloves: Butterfly knives, Karambit, Sport Gloves increase the gold-tier EV contribution significantly
- Cases with valuable Coverts: Cases containing AK-47, AWP, or M4 Covert skins have higher red-tier contributions
- Older discontinued cases: Rare cases often have higher case costs that offset any content value advantages
Always check current Steam Community Market prices before calculating, as values fluctuate constantly.
The Mathematics of Loss
According to the Law of Large Numbers from probability theory, your actual results will converge toward the expected value over many trials. This means:
- Opening 10 cases: Results highly variable, big wins or losses possible
- Opening 100 cases: Results starting to cluster around expected loss
- Opening 1000+ cases: Almost certain to be within a few percent of expected loss
This is why case opening should be treated as entertainment, not investment. For more on responsible approaches, visit BeGambleAware's safer gambling resources.

Frequently Asked Questions
Is it possible to profit from CS2 case opening?
Statistically, no. Case opening has negative expected value by design. While individual players can get lucky with knife drops, the vast majority lose money over time. If you open enough cases, your results will converge toward the expected loss percentage (typically -40% to -80% depending on the case).
Which cases have the best break-even chances?
Cases with extremely valuable knife finishes (like those containing Butterfly or Karambit knives) and high-value Covert items theoretically have better expected values. However, even the "best" cases still have negative expected returns. The case market is efficient - if a case had positive EV, traders would buy it until prices normalized.
Should I factor in Steam Market fees?
If you plan to sell your items, yes. Steam takes 15% of all market sales (5% Steam fee + 10% CS2 fee). Our calculator shows pre-fee values by default. If selling, reduce expected values by 15% for realistic profit projections. Use our Market Fee Calculator for precise fee calculations.
Why is my break-even so high?
The break-even threshold shows how many cases you'd need to open, with perfect statistical luck, to have your returns equal your costs. Because expected value is almost always negative, you'd need above-average luck (more knives than statistically expected) to actually break even. The higher the EV deficit, the more luck required.
How accurate are these calculations?
The probability calculations are 100% accurate based on Valve's disclosed drop rates. The value estimates depend on the prices you input - for accurate results, use current Steam Market prices. Remember that actual results will vary significantly due to random variance.
Is buying skins directly better than opening cases?
Almost always, yes. If you want a specific skin, buying it directly from the Steam Market is typically 50-90% cheaper than the expected cost of opening cases until you get it. Case opening only makes sense if you enjoy the gambling aspect as entertainment, not as a way to acquire specific items.
