A one-ounce gold bar is worth $3,318.70, as of June 30, 2025. Gold prices fluctuate daily, so if you’re thinking about buying or selling this year, here’s what you should know about its current value and whether it’s still a smart investment in 2025.

Gold Bar Prices in 2025: Breakdown by Size

Gold bars vary in size and this can impact the price. Take a look at these common sizes of bars and their potential cost.

Pro Tip

Be sure to check the spot prices of gold daily since they are impacted by global supply, demand, inflation, interest rates and geopolitical events.

Check reputable sources like Kitco, JM Bullion or Reuters for the spot price. 

What Affects the Value of a Gold Bar?

The primary factor that impacts how much a gold bar is worth is the spot price. Weight, purity, brand, mint and market demand also impact valuation. 

Gold Spot Price

The gold spot price is the current price of one ounce of gold based on supply, economic factors and demand. When interest rates are lower, gold becomes more attractive. Also, when fiat currencies weaken, gold price rises as a hedge against inflation. 

Weight and Purity

Gold bars come in various sizes. The most popular size is one ounce or 31.1 grams. Other sizes include: 

• 10 ounces: This bar weight is preferred by high-end investors. 
• 1 kilogram: Institutional buyers prefer this weight. 
• 400 ounces: This is the standard size for central banks and large financial institutions.

Investment-grade gold bars are usually 99.99% pure or 24 karats.

Brand and Mint

Recognized mints give guarantees on weight and purity. Some reputable brands include the following:

• PAMP Suisse
• Credit Suisse
• Valcambi from Switzerland
• Perth Mint from Australia
• Royal Canadian Mint from Canada

Generic bars that may trade at a lower premium lack the same level of purity and trust. 

Market Demand

Global events have an influence on gold prices. When the economic market experiences a downturn, gold becomes more in demand. It represents a safer asset. For example, during the Ukraine conflict in 2022, gold prices rose by over 8%.

If other countries are buying gold, this often drives up demand. Also, when the stock market is volatile in terms of the equities market, gold becomes a more attractive purchase. Scarcity, especially when production declines, drives the gold price higher.

How To Calculate the Value of a Gold Bar

A simple formula is used to calculate the value of a gold bar. The industry uses the following formula: 

• Gold Bar Value = Bar Weight X Gold Spot Price

Here are some common calculations based on a $3,318.70 per troy ounce.

What Does It Really Cost To Buy a Gold Bar?

Buyers don’t just pay the spot price on gold. There are other costs that are added to the gold price. You will likely have to pay for a dealer’s premium and storage and insurance costs.

Good To Know

The spot price isn’t the full amount you’ll pay for gold. Depending on where and how you buy, costs like dealer premiums and fees can add up.

• Estimated Total Cost = Spot Price + Premium 

Premium Fees

Dealers add a premium. A premium is added to the spot price to cover the manufacturing, distribution and profit of the bar. Typical premiums range from 1.5% to 15%. 

For example, one-ounce bars have a 2% to 8% premium. Larger bars typically have a lower premium.

Premiums are impacted by brand reputation, bar size, market demand and the payment method.

Storage and Insurance Costs

Owning gold requires storage that is secure. Here are a few options.

Home Safe

You can choose to store your gold at your home. This may require a one-time purchase of a safe.

• Safe costs can range from $200 to $2,000 or more.
• Insurance costs can range from 0.5% to 1% of gold’s value per year. 

Safety Deposit Box

You may not feel comfortable storing gold at home. Another option is to store your gold in a safety deposit box at a bank.

• You will pay an annual fee for the safety deposit box that can range between $50 to $300. 

Private Depository

Storing your gold at a private depository is also an option. Brinks and Loomis are two depositors.

• The fee is 0.5% to 1% per year based on the total value of stored gold.
• Insurance costs are often included in the yearly fee. 

Where To Buy and Sell Gold Bars

There are several places to buy and sell gold bars. Check out this list: 

Marketplaces

The major marketplaces that buy and sell gold bars include APMEX, JM Bullion, SD Bullion, Kitco and Provident Metals.

Local Coin Shops

Buying at a local coin shop means you won’t experience a shipping delay. Instead, the transaction is immediate. You also have the benefit of talking to someone in person about what you’re purchasing. 

The downsides of buying local may mean you have to pay a higher premium because of lower volume. Buyback options may be limited too. 

Banks

Purchasing gold at a bank comes with some built-in guarantees. Banks are trusted institutions and sell LBMA-approved bullion.

However, banks carry a limited selection, and you may have to be an account holder to purchase gold. Not all banks offer this service, so it’s a good idea to call your local branch to confirm.  

Bullion Exchanges

At bullion exchanges, you can trade gold ETFs or futures instead of bars. Some of the more popular bullion exchanges include:

• LBMA
• New York Mercantile Exchange (COMEX)
• Shanghai Gold Exchange (SGE)

Bullion exchanges often involve institutional investors. 

Gold Auctions

Gold auctions offer prices below market volume and the opportunity to buy rare coins. However, there is also a chance of counterfeit coins, so buy at your own risk. 

Gold Bars vs. Other Ways To Invest in Gold 

Gold bars aren’t the only way to invest in gold. Here is a side-by-side comparison of other ways to invest in gold. 

Is a Gold Bar a Good Investment in 2025?

Gold has a pretty solid track record as a physical asset. Whether buying minted bars or investing in gold ETFs, most financial advisors would consider gold a safe-haven investment that can diversify your portfolio while maintaining a high degree of liquidity. 

What’s more, the variety of investment types and physical gold sizes and weights makes gold accessible to most investors. However, weighing the various investing options against your financial goals is important. 

While physical gold can be a safer investment than stocks or ETFs, you’ll pay more for the bullion or coins than the raw gold content is worth. In addition, capital gains from the sale of physical gold are taxed at a higher rate than gains from gold stocks and ETFs.
