SMC calculates the Steam market fee and shows you an amount of money which you will receive after you sell a product on the market.
The easiest way to calculate which amount of money you'll receive after you sell a product on the Steam market!
An easy to use popup extension could be really helpful when you need to calculate the Steam market fee.
You don't have to enter the Steam selling page to get the final price, with this extension you'll know it earlier and decide to sell or not to sell an item :)
Thank you for downloading and enjoy the extension!
