Case Opening EV Calculator
Every reputable case site publishes per-item drop rates. This calculator turns those numbers into the only figure that matters: EV = Σ (item value × probability). The rows are pre-filled with the worked example from our case odds guide, replace them with the case you're evaluating.
Benchmarks from our testing
Across the sites in our directory, measured case edges cluster around 5% at the best-value end (SkinRave's stated edge), ~10% for most large platforms, and 25–30%+ on filler-heavy novelty cases. If the probabilities don't sum to 100%, the site's published odds are incomplete, treat that as a red flag in itself. Item values should be real market prices, not the site's internal prices, if the site inflates its price feed, the true edge is higher than this calculator shows.
Every platform in our directory is tested with real deposits and withdrawals, and re-checked monthly.
