What is Trade Up Calculator?

Used in games like CS:GO/CS2 to calculate the outcome of the Trade Up Contract predicting which skins you'll receive based on the float values and collections of the 10 input skins.

Trade Up Calculator Formula / Method

Floatout=MinFloat+(MaxFloatMinFloat)×(sum(Floati,i=1..10)/10)Float_out = MinFloat + (MaxFloat − MinFloat) × (sum(Float_i, i=1..10) / 10)
P(skin)=1/NumberofoutcomesincollectionP(skin) = 1 / Number of outcomes in collection

Trade Up Calculator Worked Example

10 input floats: 0.15, 0.12, 0.18, 0.14, 0.16, 0.13, 0.17, 0.11, 0.19, 0.10

Floatavg=sum(floati)/10=0.145Float_avg = sum(float_i)/10 = 0.145
Floatout=0.06+(0.800.06)×0.145=0.167Float_out = 0.06 + (0.80 − 0.06) × 0.145 = 0.167

Result: output skin float 0.167 (Field-Tested range).
