Profit = Sale Price - Purchase Price - Platform Fees - Shipping Costs. Our calculator handles all the math, including complex fee structures like eBay's tiered rates.
Most successful resellers target 30-50% profit margin after all fees. For quick flips, 20% might be acceptable. For rare items, 100%+ margins are common.
ROI (Return on Investment) = (Profit / Purchase Price) × 100. A 100% ROI means you doubled your money. It helps compare deals - a $5 profit on a $5 purchase (100% ROI) is better than $10 profit on $50 (20% ROI) when capital is limited.
Facebook Marketplace and Vinted have the lowest fees (often 0% for local sales). For shipped items, fees range from about 10% (Mercari) to 20% (Poshmark). Use our comparison feature to see exact fees for your sale price.
We update our fee data regularly to match current platform rates. Fees are accurate within 0.5% for most platforms. Always verify current rates on the platform for final decisions.
