Precious Metal Calculator

Use this tool to calculate the total value of your precious metal collection. This precious metal calculator saves the line items on your computer, using local storage, and preforms all calculations in your web browser, using your own CPU. Therefore, the details of your holdings remain secret, because the calculator transmits no data online or over the Internet.

How to use the Precious Metal Calculator

The calculator automatically fills the Spot gold price and the Spot silver price boxes with the latest spot prices each time you navigate to this page. The first time you use the precious metal calculator, one line displays 1 oz of silver at a cost of $10 for demonstration purposes. We will write over it in the procedure below.

Assume you have 50 1oz American Eagle silver coins, a 1kg silver bar, a 100g gold bar. To determine the value of your collection:

  1. In the first line of the calculator, type 50 in the Weight box, select Oz in the Unit box and Silver in the Metal box. This represents your imaginary 50 ounces of American Eagles.
  2. Empty the Cost box for now. We’ll talk more about that later. You can delete the contents of the box or type a zero to empty it.
  3. Click Calculate. The calculator uses the spot price to determine the value of your coins. Also, clicking Calculate saves the data on your computer.
  4. Click Add Row. A new row appears below the first row.
  5. Type 1000 in the Weight box and select Gram in the Unit box. Select Silver in the Metal box because this represents your kilogram bar of silver.
  6. Click Add Row again.
  7. Type 100 in the Weight box and select Gram in the Unit box. Select Gold in the Metal box because this represents your 100 gram gold bar.
  8. Click Calculate to see the total value of your imaginary stash.

You can change the values of any box at any time and click Calculate to display the new values. Likewise, you can click the trash can to delete a line.

Calculating Gains and Losses

You can optionally use the precious metal calculator to determine unrealized gains or losses. If you’re not interested in this information, simply leave the Cost boxes blank, or fill them with zeroes.

To determine your gains or losses, fill in the Cost box on each row in the calculator table. The cost reflects the the total cost of the row, not the unit cost. In other words, the cost is not multiplied by any other fields in the table. It is simply the total cost of the line item. Personally, when I enter the cost, I like to include the cost of shipping too. However, it’s up to you to determine what cost means to you.

Calculating Future Prices

Imagine if silver prices went to $50 again. Likewise, what if gold went over $2,000 or $5,000 or even more? What would your precious metals be worth then? The precious metal calculator makes it easy to find out. Simply type your wildest fantasy, or nightmare, numbers in the Spot gold price and the Spot silver price boxes and click Calculate.

How the Precious Metal Calculator Works

The calculator automatically populates the current spot prices in the Spot gold price and the Spot silver price boxes. You can, however, type any value you want in the boxes. It’s fun, for example, to see how much your stack would be worth if precious-metal prices went to the moon.

Click the trash can to remove a row. If you want to keep track of your gain or loss, fill in the Cost boxes with the amount it cost you to purchase the silver or gold. If you don’t know the costs or aren’t interested in the gain or loss, put a zero in the cost box.

Precious Metal Privacy

As mentioned above, all of the data you enter in the calculator remains on your computer only. Consequently, the details concerning the size of your precious metal collection are safe with you. Furthermore, this entire site is completely devoid of tracking scripts, third-party or otherwise. No other bullion comparison site can make this claim.

  1. My elderly mother purchased gold/silver coins from Rosalind Capital. She paid $10,300 total for 20@ 2.5 oz. silver proofs and 5@1/4 oz. gold proofs.

    I know nothing about premium coins but what I found is that this is about $7800 over spot price. Am I wrong?

    1. Hi James,
      That sounds about right. It’s possible your mother bought collector’s coins, which are also called numismatics, or numismatic coins. Collector’s coins are often worth more, sometimes a lot more, than the value of their precious metal-content, but you would have to take the coins to a trustworthy local coin shop or other expert to find out their real value.

      Personally, from an investment perspective or a hedge against economic disaster, I prefer bars over coins, and when I buy coins, I do not buy collector’s coins. Non-collector’s coins and bars can often be bought on sale with small margins above spot price, and if you’re in it for the long haul, there is always the possibility that your “normal” coins become collector’s items. I’ve commented on this here:
