Reselling or flipping items can be a profitable business, but accurate profit calculation is essential for success. Understanding all costs involved, including platform fees, shipping, and additional expenses, helps you price items correctly and maximize profitability. This calculator helps you determine your true net profit after all expenses are deducted.
Purchase Cost
The amount you paid to acquire the item, including any taxes or fees paid at purchase.
Platform Fees
Commission or selling fees charged by platforms like eBay (12.9%), Poshmark (20%), Mercari (10%), or Facebook Marketplace (10%).
Shipping Costs
Cost to ship the item to the buyer, unless the buyer pays for shipping separately.
Additional Expenses
Packaging materials, cleaning supplies, photography equipment, storage costs, or any other expenses related to the sale.
Understanding how to calculate your reselling profit helps you make informed pricing decisions:
Net Profit
Net Profit = Selling Price - Purchase Cost - Platform Fees - Shipping - Additional Expenses
The actual amount of money you keep after all expenses are deducted.
Profit Margin
Profit Margin % = (Net Profit / Selling Price) × 100
The percentage of your selling price that represents profit. Higher margins indicate better profitability.
Return on Investment (ROI)
ROI % = (Net Profit / Total Investment) × 100
Measures the efficiency of your investment. A 100% ROI means you doubled your money.
Break-Even Price
Break-Even = (Total Costs) / (1 - Platform Fee %)
The minimum selling price needed to cover all costs without making a loss.
