CS2 trade up sites and calculators compared (2026)
Short answer: every good trade up site computes the same odds and float, because the rules are fixed. They differ in price data, fee handling, whether they model the 5-Covert knife contract, whether they find contracts for you and what they ask of you (login, paid tier). Here is the comparison, including us.

Related questions
What is the best CS2 trade up site?
For checking a contract with live prices, a fee setting and no account, CS2TradeUp.gg. If you want prices from one specific marketplace among 20–30, CS2Locker or Skinbase list more sources. Most players use a calculator to verify and a finder to discover; both are on this site.
Are trade up calculators accurate?
The odds and the float formula are fixed by the game, so every serious calculator gives the same odds and float. What differs is the price data (which markets, how fresh, lowest listing per wear or “any wear”) and whether fees are included – that is what changes the profit estimate.
Which calculators support the 5-Covert knife contract?
On 2026-10-20: CS2TradeUp.gg (all 43 cases), Skinbase and SkinSniper model it; csdb.gg and steamdb.com state that they do not; CS2Locker describes the rule in its FAQ.
Are CS2 trade up sites safe?
A calculator that works without your Steam login or trade URL only computes numbers. Be careful with any site that asks you to log in with Steam for basic features or to send items to a bot.
