Planning a Big Topper trade-up
Creepy Crawly Collection has 6 Commando outcomes. A Mercenary input from this collection contributes 1.67% to the chance of this specific item. Repeating one input name or mixing different names within the same tier does not change that share.
| Inputs from this collection per 10-item contract | 1 contract | 5 contracts | 10 contracts |
|---|---|---|---|
| 10 of 10 | 16.67% | 59.81% | 83.85% |
| 5 of 10 | 8.33% | 35.28% | 58.11% |
| 1 of 10 | 1.67% | 8.06% | 15.47% |
These are theoretical, independent attempts with an unchanged recipe, not forecasts or case-opening odds. Five contracts consume 50 inputs; ten consume 100. Other inputs must be compatible and come from other collections. All ten inputs must be Non-Strange and the same grade. A higher chance of this item is not necessarily a higher chance of profit.
Buy Big Topper directly or attempt a trade-up?
Compare the target’s eligible sell listing with the total cost of ten compatible inputs. A trade-up buys a chance at every possible result—not just Big Topper. Evaluate all 6 outputs from this collection, plus any outputs introduced by mixing collections. Use eligible backpack.tf buy orders for estimated resale proceeds; an asking price is not an instant cash-out price.
Missing or stale output quotes mean profitability is unconfirmed, not that the output is worth zero. A saved listing also does not prove that ten copies are available. Check timestamps, quality, and stock before spending.
