FBA Economics Evidence Note: Rob's May 12th benchmark ($8,785 gross sales across 12 days on 61 units) translates into a full month run-rate of $21,962.50 with $1,900.58 pre-tax net margin (21.63%). However, because Amazon retains a 25% rolling reserve ($2,196.25) across settlement cycles while immediate inventory replenishment requires $3,689.70 in COGS, rapid scaling creates an immediate working capital strain without external float.
Seller ledger and cash hold arithmetic
Read the explanation
Entered gross revenue eight thousand seven hundred eighty-five dollars times forty-two percent gives cost of goods three thousand six hundred eighty-nine point seven. Fifteen-percent referral assumption gives thirteen hundred seventeen point seven five. Bars compare components at point one five pixels per dollar. These entered percentages do not establish actual platform rates or a seller account. Source fulfillment cost multiplies sixty-one units by six point eight five dollars to four hundred seventeen point eight five. Inbound shipping sixty-one times one point two five gives seventy-six point two five. Bars share one point two pixels per dollar. Neither charge is read from a live account or verified fee schedule. Assigned reserve hold twenty-five percent of gross locks two thousand one hundred ninety-six point two five, leaving six thousand five hundred eighty-eight point seven five immediate disbursement. Bars compare held and remaining cash at point zero eight pixels per dollar. Source computes profit separately after eight cost categories; disbursement is not net profit or proof of payout. Complete original raw ledger/reset/native resize/first-footer evidence remains required.
