HelloProfit uses a standard formula for calculating gross ROI.
ROI = (Gross Sales - Expenses) / Cost;
Gross Sales: Total gross revenue received from the customer. (Gross Sales + Tax)
Expenses: FBA Fees, Promos, Product Cost, Shipping Cost & Ad Cost. For payout reports we include all expenses reported on the settlement report.
Cost: Product Cost, Shipping Cost, Ad Cost and Tax (If enabled).
