Doesn’t seem to calculate costs correctly – Salecalc for eBay Calculator Review

I inputted that something cost me $60. The app was telling me that for me to break even I’d have to list my item for $59.63... I’m already at a loss and we haven’t even thrown in shipping costs, eBay fees and PayPal fees.
