1 kilogram gold bars explained
What is a 1 kilo gold bar?
A 1 kilo gold bar is a cast gold bullion bar containing exactly 1,000 grams of pure gold, usually with 99.99% purity (999.9 / 24 karat). This is equivalent to approximately 32.15 troy ounces. The bar carries the producer's stamp, the weight, the gold content, and a unique serial number.
It is the largest bar that private and corporate investors typically purchase in practice, and the format with the lowest premium per gram, intended for those who want to allocate a substantial amount into physical gold.
Why invest in 1 kilo of gold?
Anyone buying a kilo of gold chooses maximum cost efficiency: this format offers the most gold for your money. The premium above the gold price for a kilo bar is typically only around 1%. For a C. Hafner kilo bar, for example, this equates to approximately €1,214 on a metal value of over €120,000.
Therefore, you pay almost exclusively for the gold itself, and barely anything for production and distribution. With smaller bars, this premium per gram increases significantly.
- Lowest premium per gram: approx. 1% above the gold value, the most favorable ratio in our entire selection.
- Maximum gold value: efficiently build a large physical position in a single bar.
- High purity: 99.99% pure gold, certified and recognized worldwide.
- Long-term store of value: suitable for those who want to tangibly lock in wealth for years to come.
On the other hand, there is a conscious trade-off to consider: a kilo bar is less flexible because you must sell the gold all at once. If you want the ability to sell in parts later on, a combination of multiple 100 gram bars might be a wiser choice. Below, you can read which choice fits your situation best.
A kilo bar is pure math: you pay the least in premiums and get the most gold for your money. The only thing you sacrifice is flexibility, because you will be selling it all at once later. Investors who are aware of this make a highly conscious choice.
Rolf van Zanten, June 2026How much does a kilo of gold cost?
The price of a kilo of gold consists of the current gold value (1,000 grams multiplied by the gold price per gram) plus a limited premium for production, certification, and secure logistics.
Because the gold price constantly moves on international markets, the price of a kilo bar changes continuously; our prices are therefore automatically refreshed every 3 minutes. You can view the current price per 1 kilo gold bar in real time for each product on this page.
Would you like to buy gold bars but want to monitor the market rate first? On our gold price page, you can see the live rate per gram, troy ounce, and kilo, including a gold price chart showing historical performance.
The premium of a kilo bar compared to smaller bars
The main price advantage of a kilo bar lies in its premium: the surcharge above the pure gold value. For a kilo of gold, this premium is the lowest in our entire range, hovering around 1%, because the fixed production costs are shared across one thousand grams.
The smaller the bar, the heavier those same fixed costs weigh per gram, and the higher the premium becomes percentage-wise. Which weight suits you best depends on your balance between this premium and your desired flexibility when selling.
Small gold bars (1 up to 20 grams)
Small bars of 1, 5, 10, and 20 grams have the highest premium per gram. For a 1 gram bar, this can easily exceed 20%. However, this comes with maximum flexibility: you can enter the market with a low amount and sell exactly as much as you want later on. This segment is ideal for those making a low-threshold start, buying periodically, or giving gold as a gift.
The international standard size: 1 troy ounce
In addition to weights in grams, there is one size that serves as the global standard: the 1 troy ounce gold bar (31.1 grams). This is the unit in which the international gold price is quoted and in which gold is traded on exchanges like the London Bullion Market.
In terms of premium, the troy ounce sits right between small and medium-sized bars, while its global recognition benefits its tradability. For investors who value an internationally current standard size, this is a logical choice.
Medium-sized gold bars (50 and 100 grams)
In the medium segment of 50 and 100 grams, the premium per gram drops noticeably, down to around 2% for a 100 gram bar. The bars remain compact and highly divisible. This is the pivotal point for investors building serious wealth in physical gold who still want the option to liquidate a portion of their position later.
Large gold bars (250, 500, and 1 kilogram)
Large bars of 250, 500, and 1,000 grams feature the lowest premium per gram, making them the most cost-efficient for large investment sums. The kilo bar forms the endpoint of this scale, with a premium of approximately 1%. The main point of attention is divisibility: you sell such a bar all at once.
Many investors therefore deliberately choose multiple bars of 100 or 250 grams instead of a single kilo bar to maintain selling flexibility while still enjoying a low premium.
| Weight | Indicative premium per gram | Flexibility upon sale | Suitable for |
|---|---|---|---|
| 1 gram | over 20 percent | very high | First purchase, saving, gift |
| 5 grams | high | very high | Accessible entry, diversification |
| 10 grams | a few percent | high | Step-by-step accumulation |
| 20 grams | a few percent | high | Step-by-step expansion |
| 1 troy ounce | average | high | International standard size |
| 50 grams | approx. 2 to 3 percent | average | Private investor |
| 100 grams | approx. 2 percent | average | Balance between premium and divisibility |
| 250 grams | slightly over 1 percent | lower | Larger position |
| 500 grams | slightly over 1 percent | lower | Large investment |
| 1 kilogram | approx. 1 percent | lowest | Largest denomination, lowest premium |
Premiums are indicative and vary based on the live gold price, producer, and stock levels.
1 kilo of gold or multiple smaller bars?
The kilo gold bar represents the format with the lowest premium within our selection and is predominantly chosen by investors who build a large position all at once.
The choice between a single kilo bar and multiple smaller bars comes down to weighing costs against flexibility. A kilo bar features the lowest premium, but you will always sell the gold all at once.
Investors who want to retain the option to liquidate part of their position down the road often opt for multiple 100 gram bars: this still secures a low premium, but adds divisibility.
- Choose 1 kilo when cost efficiency and long-term value storage are your top priorities, and you do not expect to sell your holding in segments.
- Choose multiple smaller bars (100, 250, or 500 grams) when selling flexibility carries more weight than securing the absolute lowest premium.
Would you prefer to explore our entire gold selection before making your choice? On our buying gold page, you will find our complete range of physical gold: from gold bars in all weights to gold bullion coins. This allows you to compare all your options in one clear overview and determine which form aligns best with your objective and budget.
1 kilo gold bars from LBMA-accredited producers
The Silver Mountain supplies 1 kilo gold bars from renowned refineries listed on the LBMA Good Delivery List, such as Umicore, C. Hafner, and Heraeus. This accreditation guarantees that the refinery meets the strictest international standards for purity, weight, and responsible sourcing.
Thanks to this status, your kilo bar is globally tradable at bank counters, professional dealers, and central banks without requiring additional testing. Kilo bars are almost always delivered as cast bars, accompanied by an authenticity certificate where the serial number matches the one stamped on the bar.
In addition to brand-new bars, we regularly offer pre-owned kilo bars: thoroughly verified for authenticity, weight, and gold content before sale, representing the sharpest pricing for those focused purely on the underlying gold value.
Insurance upon delivery and storage
With a purchase valued at over € 120,000, it is important to know how your gold is insured during transport and thereafter. The Silver Mountain ships every kilo bar fully insured, whether you choose secure armored transport or our personal delivery service.
The coverage runs until the moment of transfer: as soon as you receive the bar following an identity check, the risk is transferred.
Beyond that, storage requires careful consideration. Storing a kilo of gold at home is possible, but please keep in mind that a standard home contents insurance policy often covers precious metals only up to a limited amount or not at all. For a bar of this value, that coverage is usually insufficient, so always check your own policy conditions.
Those who do not wish to run this risk at home opt for allocated storage through our sister company Edelmetaal Beheer Nederland (EBN).
Securely storing a kilo of gold
Not everyone feels comfortable keeping a kilo of gold at home. Therefore, you can choose to store your kilo bar via our sister company Edelmetaal Beheer Nederland (EBN). Your bar is stored on an allocated basis: registered by name and bar number, physically segregated, and fully insured within secure vaults in Houten or in Switzerland, via Loomis International.
The bar remains entirely your property, and you can sell your gold directly back to us straight from the vault. You simply select storage when checking out your order.
Safely and securely buying a kilo of gold at The Silver Mountain
With a purchase of this scale, reliability is at least as important as the price. The Silver Mountain has been active since 2008, operating as a trusted authority in precious metals for over 17 years, and stands as the largest bullion dealer in the Netherlands.
We are registered with the AFM for offering investment objects (license number 12048860). This AFM supervision applies specifically to precious metals combined with storage; transactions where the gold is physically delivered, such as safe transport or in-person pickup, fall outside this scope.
- LBMA accredited: exclusively certified bars from world-renowned producers.
- Live prices: directly linked to the current gold spot price; you always purchase at the prevailing value.
- Insured delivery: handled via specialized secure logistics or our own dedicated delivery service (featuring ID verification, exclusively to your specified delivery address), fully insured until the handoff.
- Personal contact: you are welcome by appointment at our offices in Baarn or The Hague.
- Allocated storage via EBN: registered by name and fully insured in Houten or Switzerland.
Safely paying for a kilo bar
When making a purchase of such a large amount, it is good to know how our payment process works. You can pay for your kilo bar via iDEAL / Wero, by bank transfer, or by debit card when you pick up the bar by appointment in Baarn or The Hague.
The most important thing to know: as soon as you place your order, we lock in the price against the current gold rate at that exact moment. Any market price fluctuations between your order and the payment will therefore no longer affect your purchase amount. Payment must then be completed within 3 business days.
Given an amount of this magnitude, please keep in mind that your bank may apply a daily transfer limit. You can usually arrange a temporary increase easily through your banking app, although this might take some time.
Are you unsure about the fastest or safest route for a large payment? Our specialists are happy to help you by phone at 035 203 1380.
Sell your 1 kilo gold bar

We provide a buyback guarantee on all our kilo bars: you can always sell your bar back to us, regardless of market price levels. Selling is facilitated through our sister company Inkoop Edelmetaal, which applies a bid price of 98.5% of the current gold price for kilo bars from LBMA-accredited producers.
Upon sale, we verify the bar for weight and authenticity; this is part of a meticulous and reliable transaction process. Inkoop Edelmetaal also purchases kilo bars that you originally bought elsewhere.

Frequently asked questions about ordering 1 kilogram gold bars
1. How much does a kilo of gold cost?
A kilo of gold costs the current gold price per gram multiplied by 1,000, plus a limited premium of approximately 1% for production and distribution. For a C. Hafner kilo bar, this premium amounts to roughly €1,200 above the raw metal value. Because the gold rate fluctuates continuously, you can view the live price in real time within the product overview; you can track the rate per kilo on our gold price page.
2. How much is a kilo of gold worth?
A kilo of gold contains 1,000 grams of pure gold, which is roughly 32.15 troy ounces. You calculate the value by multiplying the live gold price per gram by 1,000. Because the premium is at its lowest for this weight, the selling price sits very close to the pure metal value. The value fluctuates daily alongside the gold market rate.
3. Is a kilo of gold VAT-free?
Yes, a 1 kilo gold bar is fully exempt from VAT. The bar consists of 99.99% pure gold and therefore comfortably qualifies as investment gold, which requires a minimum purity threshold of 99.5%. Consequently, you pay 0% VAT on your purchase across the entire European Union, whether you buy as a private individual or a corporate investor.
4. Why is the premium on a kilo bar so low?
The premium on a kilo bar is the lowest among all weights because the fixed manufacturing and overhead costs are distributed across a substantial 1,000 grams of gold. With a small bar, those identical costs weigh heavily on a tiny amount of gold, resulting in a high percentage premium. For a kilo bar, the markup remains limited to roughly 1% above the gold value.
5. What are the dimensions of a kilo of gold?
Due to the exceptionally high density of gold, a 1 kilo gold bar is remarkably compact: a cast kilo bar is roughly the size of a standard smartphone, with dimensions around 89 x 40 x 15 mm. The exact dimensions vary slightly per manufacturer and casting method and are listed on the respective product page.
6. Can I have a kilo of gold safely stored?
Yes, you can have your kilo bar stored through our sister company Edelmetaal Beheer Nederland (EBN). Your gold is kept on an allocated basis: registered to your name, physically isolated from other gold holdings, and fully insured inside highly secure vaults in Houten or Switzerland. The bar remains entirely your property and can be liquidated instantly from storage at any moment.
7. Is 1 kilo of gold suitable for every investor?
No, a kilo bar is primarily geared toward individuals looking to allocate a larger sum of money at one time while securing the lowest premium per gram. Those who prioritize liquidation flexibility when selling are better off choosing multiple smaller bars. Furthermore, gold is subject to market fluctuations and may not automatically align with every investment objective or horizon.
8. What is better: 1 kilo of gold or multiple 100 gram bars?
A kilo bar is more efficient per gram, whereas multiple 100 gram bars offer superior flexibility during resale. If you want the freedom to sell off parts of your holding over time, 100 gram bars prove much more practical. If your primary objective is capturing the absolute lowest premium per gram, a single kilo bar is more advantageous. The ideal choice depends on your exit strategy and investment horizon.
