FAQ
What does ROI mean for CS2 items?
ROI is your profit divided by your total cost, shown as a percentage. It helps compare trades even when prices differ.
Does this include marketplace fees?
Yes—enter your fee % and the calculator subtracts fees from gross proceeds to show net proceeds, profit, and ROI.
How is break-even sell price calculated?
It finds the per-unit sell price that makes net proceeds equal your total cost, accounting for fee % and any extra sell costs.
What are “extra buy” and “extra sell” costs?
They are flat totals (not per unit) you can use for any additional costs you want included in profit (e.g., listing costs, transfer costs).
What does annualized return show?
If you enter days held, the tool shows an annualized rate (CAGR and simple). It’s useful for comparing short vs long holds.
Can I calculate ROI for multiple skins/cases at once?
Yes—paste multiple lines into Bulk input and the tool will show per-item ROI plus total cost, total profit, and total ROI.
Is this only for Steam Market?
No—use it for any marketplace or direct trade; just enter the fee % and any extra costs that apply to your sale.
