Mathematical Audit

How Thrift Flip Reseller Profit Is Calculated

Profit is calculated by subtracting total expenses (purchase cost, platform fees, shipping, and supplies) from gross revenue based on items sold.

Items Sold = Items Purchased × (Sell-Through % ÷ 100)
Gross Revenue = Items Sold × Avg Selling Price
Platform Fees = Gross Revenue × (Fee % ÷ 100)
Monthly Profit = Gross Revenue − Purchase Cost − Platform Fees − Shipping − Supplies
Effective Hourly Rate = Monthly Profit ÷ Total Hours

Purchase cost is based on all items bought, not just those sold. Unsold inventory reduces your effective profit margin. Sell-through rate is the most critical variable.
