What This Comparison Measures

The tool separates bar-size economics from brand and product features. Each bar is converted to fine-gold grams so that a 5-gram bar and a 100-gram bar can be compared meaningfully.

Why Size Changes Economics

Small bars can have higher manufacturing and packaging costs per gram. Larger bars can spread those costs over more gold, but may require more capital and may have different resale liquidity.

The cheapest fine-gold gram is not automatically the best fit if you value divisibility and resale flexibility.

Practical Buying Decision

Use the ranking to identify the lowest normalized cost, then separately consider how much capital you want tied up in one item, how easily you may need to resell part of the holding and whether the product has a strong secondary market.

Frequently Asked Questions

How does bar size affect premium?

Premiums can differ because production and commercial costs vary by format.

Are larger bars always cheaper per gram?

No.

Should bars be compared by cost per gram?

Yes, but also consider fine-gold content and resale factors.

Why compare multiple sizes?

To quantify whether size creates a real unit-cost advantage.
