CS2 trade-ups built from real, buyable listings

We continuously scan CSFloat, DMarket, Skinport, and Buff.market for real listings, then test thousands of input combinations across 45+ float targets. Every result is built only from listings currently for sale.

Prices come from real marketplace data: CSFloat sale history (primary), DMarket listing floors, and Skinport prices. All prices are estimates — actual prices may differ at time of purchase, especially after trade lock periods.

Yes. All prices are estimates based on current market data. Items purchased from marketplaces have trade lock periods during which prices can change. "Profitable" means profitable at current estimated prices, not guaranteed profit.

Verify checks whether every input listing still exists on its marketplace and at what price. The trade-up's cost, profit, and ROI update from the response.

Pro users can claim a trade-up to hide its listings from other TradeUpBot users for 30 minutes while they buy. Buyers on the marketplaces themselves can still purchase the inputs — a claim removes TradeUpBot competition, it doesn't reserve listings.

Profit is real but conditional. TradeUpBot builds every trade-up from actual buyable listings on CSFloat, DMarket, Skinport, and Buff, then prices the exact output float from real sales rather than a condition average. A contract is profitable only if the output sells for more than your ten inputs cost after marketplace fees — and listings can sell or move before you act, so verify before buying.

The output float is deterministic: each input's float is normalized within its own min–max range, the ten normalized values are averaged, and that average is mapped onto the output skin's float range. Change one input's float and the predicted output condition can change. This is why exact input floats — not condition averages — decide whether a contract lands in Factory New, Minimal Wear, or Field-Tested.

On the trade-ups board, TradeUpBot adds each marketplace's buyer fee to the input listing price: CSFloat 2.8% + $0.30, DMarket 2.5%, Skinport 0%, Buff 3.5% + $0.15. Output estimates are netted at CSFloat's 2% seller fee, whichever marketplace the price data came from. In the calculator, cost is the listed price with no buyer fee added.

A trade-up can produce different output skins, each with a probability set by how many inputs come from its collection. Outcomes above cost is the summed probability of the outcomes whose after-fee value exceeds your total input cost. At 70%, outcomes carrying 70% of the probability are valued above cost at current prices, and the rest are worth less than you paid. The output is random, so any single trade-up can land below cost.

Most calculators price an output at its condition average — the blended price of every skin in that wear band. TradeUpBot prices the exact predicted output float from nearest real sales, so a clean 0.16 Field-Tested is valued differently from a worn 0.37 Field-Tested. That float-exact pricing is the core difference and is why the same ten inputs can look profitable here and break-even elsewhere.

TradeUpBot continuously scans marketplace listings and refreshes trade-ups throughout the day. Free users see contracts on a delay; Pro users see them immediately. Always use Verify before buying to confirm a contract's inputs are still listed at the expected prices.

Some are, at current prices, but margins move. Margins come from price gaps between marketplaces and from float-exact output pricing, and both close as listings sell. TradeUpBot's live table shows contracts whose expected value after fees is above cost at this moment, built from listings you can actually buy. Outcomes are random, returns are never guaranteed, and every contract should be verified before purchase.

Yes. A trade-up consumes all ten inputs, and the output is drawn by probability from the input collections. If the drawn output sells below your input cost after fees, the contract loses money. That is why TradeUpBot shows the share of outcomes above cost and a bounded best and worst case for every contract instead of a single expected-value number.

It changes hour to hour as listings sell. The live trade-ups page ranks current contracts by expected profit, ROI, and share of outcomes above cost, each built from real listings on CSFloat, DMarket, and Skinport. Ranked results update continuously, so the current best contract is always the top of that list rather than a fixed answer.
