Formula and how it works
Example with real numbers
Here is the Gold Melt Calculator using the default values shown in the calculator above:
Inputs
| Weight (grams) | 20 |
|---|---|
| Karat | 14K |
| Gold price per troy ounce ($) | 3,800 |
Results
| Melt value | $1,425.35 |
|---|---|
| Pure gold content (g) | 11.67 |
With these inputs the calculator returns Melt value: $1,425.35. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Weight (grams) from 20 to 24 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Melt value | $1,425.35 | $1,710.42 | +20% |
| Pure gold content (g) | 11.67 | 14 | +20% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
