CS2 Trade-Up FAQ

Common Questions

Is CS2 trade-up profit real or just theoretical?

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.

How is the output float of a trade-up determined?

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.

What marketplace fees does TradeUpBot account for?

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.

What does "outcomes above cost" mean?

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.

Why does TradeUpBot disagree with other trade-up calculators?

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.

How often is the data updated?

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.

Are CS2 trade-ups still profitable in 2026?

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.

Can you lose money on CS2 trade-ups?

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.

What is the best CS2 trade-up right now?

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.

Do you need an account to use TradeUpBot?

No. Browsing trade-ups, skin pages, collections, and the calculator is free without an account. Signing in with Steam is free. Verify and Claim are Pro features.
