Is flipping Costco gold profitable after taxes? A worked example
Using today's live numbers — 100 Gram Gold Bar PAMP Suisse Lady Fortuna Veriscan (New In Assay) at $14,799.99, spot at $4,522.90/oz, best live buyer bid $14,447.26 from Ali Incentive:
| Costco price | $14,799.99 |
|---|---|
| − Cashback (Executive 2% + card 2%) | −$592.00 |
| + Sales tax (exempt-state example) | $0.00 |
| = Effective cost | $14,207.99 |
| Sale to Ali Incentive (after fees) | $14,447.26 |
| Net profit per bar | $239.27 (1.7%) |
The same purchase shipped to Washington (6.5% sales tax since its exemption was repealed January 2026) would swing the result by roughly $962 — which is why the state selector matters more than any other input.
How the math actually works
- Cashback stacks on the buy. Costco Executive membership returns 2%; a 2%-cashback card doubles it. Both apply to the full price, cutting your real cost ~4% before the bar arrives.
- Sales tax is the deal-breaker input. Most states exempt investment bullion (see the table below) — but six jurisdictions still tax it, and tax alone usually exceeds the flip margin.
- You sell at bid, not ask. Live buyer bids for Costco bars typically sit near spot; your margin is cashback minus Costco's premium minus fees.
- Breakeven premium is the number to watch. It's the highest Costco premium at which your flip still clears $0. Above it, wait for a better window.
Do you pay sales tax on Costco gold? State by state
Costco charges sales tax based on where the order ships ("where the order is ultimately shipped to or picked up" — Costco's published policy). For a single 1oz bar (~$14,800), only Hawaii, Maine, New Mexico, Vermont, Washington, and DC collect tax — every threshold state's cutoff sits below one bar's price. Last reviewed 2026-07-14. This is not tax advice; Costco's checkout is ground truth.

How to sell Costco gold bars
Bulk buyers quote live bids for sealed Costco bars (PAMP/Rand assay cards keep full value — don't open them). The calculator's venue list shows the live bids we track right now. Local coin shops and marketplaces can beat mailed-in bids but add spread, fees, or meetup risk. Whatever the venue: you're selling at bid — the flip works when cashback exceeded the premium you paid, not because the bar "went up."
Is Costco gold worth it?
As a flip, the margin is real but thin and timing-dependent — do the math above per window. As a buy-and-hold purchase, Costco's premium is consistently among retail's lowest (our live tracker shows the premium over spot updated continuously, and the weekly report archives every restock).
FAQ
What premium does Costco charge over spot?
Right now: 1.8% on the featured bar. Historically it oscillates roughly 2–5%.
How many gold bars can you buy at Costco?
Costco caps precious-metals purchases per membership per day; limits have varied by item. Check the product page cap before planning a multi-bar flip — the calculator's quantity input scales everything.
What's the Costco gold bar resale value?
Whatever the best live bid says — currently $14,447 at Ali Incentive.
Does the "Costco gold hack" actually work?
The "hack" is exactly this page's math: stack Executive + card cashback, buy at a low premium, sell near spot. It works when the numbers above are green — no secret beyond arithmetic and timing.
Do I owe income tax on flip profits?
Capital-gains rules for collectibles can apply to bullion sales — separate from the sales-tax table above. Not tax advice; ask a professional.
