What Is a Trade Up Calculator?

A trade up calculator simulates the odds and possible outcomes of a CS2 trade‑up contract. By inputting the 10 skins you’re willing to sacrifice, the tool predicts which skin you could receive next, its float value, and the potential profit based on current market prices. This helps you make data‑driven decisions instead of relying on guesswork.

How to Use the SIH Trade Up Calculator

Using the SIH trade up calculator is straightforward. Follow these steps to get accurate predictions:

  1. Open the SIH calculator page and select “Trade Up” from the main menu.
  2. Choose the 10 skins you want to use as inputs. You can either drag them from your inventory or search the built‑in database.
  3. Set the rarity filter if you want to focus on specific tiers (e.g., Mil‑Spec to Restricted).
  4. Click “Calculate” to see all possible output skins, their probabilities, and the expected profit or loss.
  5. Use the results to decide whether the trade‑up is worth performing, or adjust your input skins accordingly.

Benefits of Using the Calculator

The SIH trade up calculator offers several advantages over manual calculations:

  • Real‑time market data ensures you always see the most up‑to‑date prices.
  • Accurate float predictions help you target specific skin conditions (Factory New, Minimal Wear, etc.).
  • Profit analysis highlights the most lucrative trade‑up combinations.
  • Saved time by automating complex probability math.

    • Untranslated source text

  • Reduced risk of over‑spending on unprofitable contracts.

Sample Trade Up Comparison

Below is a quick reference table that compares three common trade‑up scenarios. The columns show the input rarity, the possible output rarity, the average float of the resulting skin, and the estimated profitability based on current marketplace values.

Input Rarity Output Rarity Avg. Float Estimated Profit
Mil‑Spec (10) Restricted 0.30 +5%
Restricted (10) Covert 0.45 +12%
Covert (10) Knife 0.60 +28%

By integrating the SIH trade up calculator into your daily CS2 workflow, you’ll consistently find the most profitable contracts, avoid costly mistakes, and maximize the value of your inventory. Whether you’re a casual player or a seasoned trader, this tool is essential for anyone looking to get the most out of their skin trade‑ups.
