CS2 Mixed Float Trade-Up Strategy Guide
Mixed Float is the most powerful advanced strategy in CS2 trade-ups. By combining cheap high-float filler skins with expensive low-float main skins, you can precisely target the output wear condition — turning a 140% ROI contract into a 400%+ one.

In a standard trade-up, all 10 inputs have similar float values. In a Mixed Float contract, you deliberately combine:
- Main skins (2–4): Low float (FN or low MW), from the collection with valuable outputs
- Filler skins (6–8): Cheap skins from any collection, at whatever float is cheapest
The average float of all 10 inputs determines the output float. By using mostly cheap fillers and a few precise main skins, you control the output wear while keeping total cost low.
How to Calculate the Right Float Mix
Target a specific average float across all 10 inputs:
avg_float = (sum of all 10 floats) / 10
Example: To get average float = 0.06 (Factory New range):
- 3 main skins at float 0.01 + 7 filler skins at float 0.082 = avg 0.0614 ✓
- 4 main skins at float 0.02 + 6 filler skins at float 0.087 = avg 0.060 ✓
TradeUpX calculates this automatically. Enable Mixed Float mode and set your target wear — the scanner finds the optimal main/filler combination.
When Mixed Float Is Worth the Extra Cost
Mixed Float costs more because low-float main skins are expensive. It's worth it when:
- FN premium is large: FN output worth 3× or more than FT output
- Main skin count is low: Needing only 2–3 expensive main skins keeps total cost manageable
- Filler skins are very cheap: The cheaper the fillers, the higher your ROI
- The net ROI exceeds standard: After accounting for higher input costs, Mixed Float still beats regular
TradeUpX compares standard and Mixed Float ROI side-by-side so you always pick the more profitable option.
