Sports Card Profit Calculator
Estimate true profit and ROI after purchase cost, grading, marketplace fees, shipping, and other selling costs.
Quick answer
Sports card profit = net sale proceeds − complete invested cost.
Net proceeds are the sale price after selling fees and seller-paid costs. Complete invested cost should include the card's acquisition cost and relevant later costs such as grading. ROI then measures net profit relative to the invested cost.
ROI = net profit ÷ invested cost × 100
