The 1 kilogram silver bar is the benchmark format for investing in physical silver. It’s also the one that costs the least per gram. Here’s everything you need to know before buying one.
Why the 1 kg Is the Most Economical Format
The price of a bar isn’t just the value of the metal. A premium is added: the cost of manufacturing, certification and distribution, expressed as a percentage above the spot price.
This premium is decreasing with weight. Making a 1 kg bar costs proportionally less than making twenty 50 g bars totalling the same weight. As a result, the 1 kg bar displays the lowest premium per gram in the range. For an investor who’s after the metal above all, it’s the most profitable format to buy.
How Much a 1 kg Silver Bar Costs
The price breaks down as follows:
- Metal value = spot price × 1000 g. At the current price, check the up-to-date amount on our silver price page.
- + premium of the format (the lowest in the range).
- + 20% VAT, applicable to investment silver in France.
Concretely, with a price of €1.66 per gram, the metal value of a 1 kg bar is €1,660. With a format premium of about 12%, you reach €1,860, then the 20% VAT brings the purchase price to around €2,230. This VAT explains the large gap between the price paid and the metal value alone; it must be factored into any profitability calculation, because the price will have to “catch it up” before any capital gain on resale.
The 1 kg Versus Smaller Formats
| Format | Premium per gram | Resale flexibility |
|---|---|---|
| 1 kg bar | the lowest | low (all or nothing) |
| 100 g bar | intermediate | good |
| 50 g bar | high | very good |
| Ounce / coins | the highest | maximum |
The message is clear: the 1 kg optimises entry cost, small formats optimise liquidity. Many investors combine the two: one or two 1 kg bars for the base, a few small bars or coins to be able to resell in small slices if needed.
Who This Format Is For
The 1 kg bar is particularly suited:
- to accumulating investors, who want to lay a base of metal at the best entry cost;
- to those with a long horizon who don’t need to resell in small fractions;
- to profiles who favour metal return over immediate liquidity.
It is less suited if you plan to resell small amounts gradually: in that case, a 1 kg bar forces you to sell everything at once. Smaller formats (100 g, 50 g) or silver coins then offer better flexibility, at the cost of a higher premium.
Buying It Well: the Points to Watch
- Demand a certified bar (recognised refiner, LBMA reference preferably), with a certificate and seal. This is what will guarantee a resale without a discount.
- Compare the premium, not the raw price: between two sellers, the one who displays the lowest premium at the same price is the most attractive.
- Check the stated weight: an investment bar weighs 1000 g of fine silver, 999 thousandths.
Where to Store It
A 1 kg bar remains compact but represents a significant value. Plan for secure storage: a home safe (with suitable home insurance, often capped for precious metals), a bank vault, or insured professional storage. And above all, keep the certificate in a place separate from the bar itself.
Reselling It Well
A 1 kg bar in its original seal is bought back as close as possible to the spot price, minus the buyer’s margin. Carefully keep the certificate: it’s what avoids the “doubt discount” at resale. For the complete method, read how to sell a silver bar at the best price.
In Summary
- The 1 kg bar = the lowest premium, therefore the best entry cost per gram.
- Don’t forget the 20% VAT in your calculation.
- Ideal for investing over the long term; less flexible for reselling in small slices.
- Certificate + seal = smooth resale.
