CS2 CASE ROI CALCULATOR
Mathematical Expected Returns based on live Steam market pricing
Our algorithms utilize Valve's official unboxing drop rates: Mil-Spec (79.92%), Restricted (15.98%), Classified (3.20%), Covert (0.64%), and Rare Special (0.26%). Calculations factor in StatTrak variants and wear condition distributions with daily market synchronization.
Can You Get a Gold with a $100 Budget?
EXPERT ANSWER
A $100 budget translates to roughly **37** case openings (at $2.65 per open, including keys). Because of the low count, your chance of pulling a gold is very small. It relies almost entirely on pure luck.
PROBABILITY ANALYSIS
The probability of **getting zero golds** in 37 consecutive opens is \(0.9974^{37} \approx 90.81\%\). This leaves you with only a **9.19%** chance of hitting a gold. Most $100 runs end with cheap Mil-spec skins.
