Resale profit & ROI
Count fees, shipping and the time you spend on a sale. Use the marketplace's actual fee basis and adjust your input if its rules differ from this simplified model.
Read the tape
What the tape leaves out
Fee = (sale + buyer shipping) × entered fee percentage + fixed fee. Profit = receipts − fees − acquisition − outgoing shipping − packaging − repair − other costs. ROI uses those non-fee cash costs as its denominator. Hourly result uses your total hours. Excludes income tax and pass-through sales tax. Zero cost or zero hours returns not applicable for the corresponding ratio.
