I think the math they use for STR is: (Sold)/(Sold + Unsold + Listed).
The STR cannot be more than 100% because of this formula.
The question is, what is considered a "good" sell-through rate?
What does the sell-through rate number mean in terms of how to price the item?
What does the sell-through rate number mean in terms of how many days will it take to sell?
From my own research, on hundreds of items over the last few months, my rough conclusions so far:
- Many low performing items have sell-through rates of 10% and lower.
- Many mid performing items have sell-through rates of 15% +- 5%.
- Many high performing items have sell-through rates of 20% and up.
