How to read this index
Every row prices the same thing — one gram of gold — so the formats can be compared honestly. The pattern never changes: the smaller the bar, the more each gram costs. Minting, assaying, sealing, and shipping a bar cost roughly the same whether it holds 1 gram or 31, so those fixed costs land on far less metal in a small bar. That is why a gram bought as a 1 gram bar costs $155.80 per gram while a gram bought inside a 1 oz bar costs $126.75 per gram at this week’s prices.
Small bars still make sense for gifts, gradual stacking on a budget, and easy resale in small amounts — you are paying for flexibility, not making a math error. If the goal is the most gold for the money, the table points the other way: buy the largest format you can comfortably hold.

Methodology
Each row uses the lowest-priced in-stock gold bar listed on agatemetals.com in that size at refresh time. Premium over spot = (bar price − weight in grams × spot per gram) ÷ (weight in grams × spot per gram). The index covers single bars only: coins, rounds, Goldbacks, sets, and multi-packs are excluded because their prices carry collectible or packaging value beyond metal weight. Prices exclude shipping and any taxes. Figures are recomputed weekly from the live catalog and the spot source named above.
Gold price per gram — FAQ
What is the gold price per gram today?
$124.63 per gram at spot, as of November 1, 2026. Bought as a bar, one gram costs more: the table above shows $155.80 per gram in a 1 gram bar and $126.75 per gram inside a 1 oz bar.
Why does a 1 gram gold bar cost so much more per gram than a 1 oz bar?
Because the fixed costs — minting, assay, sealed packaging, handling — are nearly the same for both bars, and the 1 gram bar spreads them over 1/31 of the metal. The premium gap in the table above is that effect, measured on live prices.
What is the cheapest way to buy gold per gram?
The largest bar format you can manage. This week the lowest premium is the 100 g bar at 1.1% over spot; per-gram cost falls steadily as bar size rises.
