Calculate how much a gold price has fallen from an original price to a lower price. See the absolute decrease, percentage decline and optional estimated decrease in the value of a specific quantity of gold.
Measure the decline from an original gold price.
The result measures the mathematical decrease between the supplied prices. It does not include taxes, dealer spreads, premiums, commissions, jewellery charges or other transaction costs.
A gold price decrease measures how much a later gold price has fallen from an earlier reference price. It can be expressed as an absolute monetary decrease or as a percentage decrease.
Percentage decrease compares the size of the decline with the original price.
Suppose gold was originally priced at 2,500 per troy ounce and later fell to 2,000 per troy ounce.
The absolute decrease is 500 per troy ounce.
The gold price therefore decreased by 20%.
A price difference simply measures the gap between two prices. A price decrease specifically describes a movement from a higher original price to a lower new price.
| Original Price | New Price | Decrease | Percentage Decrease |
|---|---|---|---|
| 2,500 | 2,000 | 500 | 20% |
| 3,000 | 2,700 | 300 | 10% |
| 5,000 | 4,500 | 500 | 10% |
The same numerical decline can represent different percentages depending on the original price.
The optional quantity field estimates how much the gold component's value has decreased for a specified amount of metal.
For example, if the gold price falls by 40 per gram and you hold 25 grams, the theoretical value decrease is:
The calculation assumes the quantity remains constant and that both prices represent the same purity and price basis.
You can calculate a decrease using common precious-metal price units, including grams, kilograms, troy ounces, tola, pennyweight and grains.
| Price Unit | Equivalent Weight |
|---|---|
| Per Gram | 1 g |
| Per Kilogram | 1,000 g |
| Per Troy Ounce | 31.1034768 g |
| Per Tola | 11.6638125 g |
| Per Pennyweight | 1.55517384 g |
| Per Grain | 0.06479891 g |
A decline in the underlying gold price can reduce the metal component of a jewellery item's value, but the retail price of jewellery does not necessarily fall by the same percentage.
Jewellery pricing can include workmanship, gemstones, design premiums, taxes and retailer margins. These elements can remain unchanged or move differently from the gold market.
A fall in the gold market price can reduce the market value of a gold holding. However, the actual realized loss on an investment can differ from the mathematical market-price decline.
Measures the decline between two comparable gold quotations.
Depends on the original purchase price, premiums, taxes, transaction costs, dealer spreads and the eventual selling price.
Physical gold may have been purchased above the reference market price, so a percentage market decline is not necessarily identical to the percentage loss on the original cash investment.
The original price establishes the reference point. This is why a decrease from 2,500 to 2,000 is 20%, not 25%.
If the price subsequently rises from 2,000 back to 2,500, that upward move is 25%, because the starting point is now 2,000.
Percentage decreases and increases therefore use different reference values when measured in opposite directions.
Both prices should use the same weight unit and comparable purity basis. For example, a 24K fine-gold price should not automatically be compared with a 22K jewellery-gold quotation without accounting for the purity difference.
The original price must be greater than zero because percentage decrease cannot be calculated using zero as the starting value.
If the new price is higher than the original price, the movement is an increase rather than a decrease. The calculator identifies this instead of presenting an increase as a positive decrease.
This calculator does not retrieve live or historical gold-market prices. You provide both prices manually.
It does not forecast future gold prices or determine whether a particular market decline is temporary or permanent.
The optional value decrease excludes taxes, dealer spreads, premiums, commissions, storage costs and other transaction expenses.
For jewellery, the calculated gold-price decrease does not account for gemstones, craftsmanship, design premiums or other components of the final retail or resale price.
Subtract the new lower gold price from the original price. The result is the absolute price decrease.
Percentage decrease = ((Original Gold Price − New Gold Price) ÷ Original Gold Price) × 100.
Yes. Enter a gold quantity and the calculator estimates the corresponding decrease in the gold component's value.
Yes. Select Per Gram and enter both prices using the same purity basis.
Yes. Select Per Troy Ounce and enter the original and new prices.
Not necessarily. Jewellery prices contain other components that may not move with the underlying gold price.
No. The original and new prices are entered manually.
No. It calculates the mathematical price decrease without transaction costs.
