Gold · Bullion Bars
A fine gold bar's melt value is the simplest calculation in precious metals: it is the gold spot price multiplied by the bar's weight. This page does it for every common bar size.
| Bar weight | Melt value |
|---|---|
| 1 g | — |
| 5 g | — |
| 10 g | — |
| 1 oz | — |
| 100 g | — |
| 1 kg (1000 g) | — |
Live spot via gold-api.com. Melt value = spot × 1 troy oz of fine metal.
Open the full calculator →Investment gold bars are struck or cast at .999 to .9999 fineness — effectively pure — so a bar's metal value is just spot price × bar weight. There is no alloy to discount and no wear to allow for, which makes bars the cleanest melt-value case there is.
The table above converts the live spot price to the common bar weights: 1 gram, 5 gram, 10 gram, 1 troy ounce, 100 gram and 1 kilogram (1000 g ≈ 32.15 troy oz). Remember that a troy ounce is 31.1035 grams, not the 28.35-gram avoirdupois ounce — a common source of error when comparing bar sizes.
Melt value is the floor, not the price. New retail bars sell for a premium over melt that covers fabrication, packaging, shipping and dealer margin, and that premium is largely lost the moment you sell. A dealer buying the bar back will typically pay melt or a little under.
| Metal | Gold (XAU), .999–.9999 fine |
| Common bar weights | 1 g · 5 g · 10 g · 1 oz (31.1035 g) · 100 g · 1 kg |
| 1 troy ounce | 31.1035 grams |
| 1 kilogram | 32.1507 troy oz |
| Melt formula | spot per troy oz × weight in troy oz |
| Premium | Retail bars carry a fabrication premium above melt |
Melt value is the value of the metal in the coin, ignoring any collector premium:
Where the fine-metal content is known, this simplifies to spot × 1 oz. The live figure at the top of this page applies that formula to the current spot price.
Illustrative melt values (per troy ounce) at example spot prices — shown for reference only; the live figure above uses the real market price:
| Example spot | Melt value |
|---|---|
| $2,000.00 | $2,000.00 |
| $2,500.00 | $2,500.00 |
| $3,000.00 | $3,000.00 |
A .999 fine 1 oz bar is worth the gold spot price per troy ounce. The live figure at the top of this page shows it, along with smaller and larger bar sizes.
A 1 kg bar holds 32.1507 troy ounces of fine gold, so its melt value is spot × 32.1507. The table above computes it from the live spot price.
New retail bars sell above melt because of the fabrication premium, but a dealer buying one back will generally pay melt or slightly under.
One troy ounce is 31.1035 grams. The 28.35-gram ounce is the avoirdupois ounce used for everyday goods and does not apply to gold.
