Gold Calculator

Estimate gold value from weight, purity, and a price per gram.

Market prices change. This is an estimate, not a quote or investment advice.

How it works

The estimate multiplies weight by purity to find fine-gold content, then applies the price you enter. It excludes workmanship, dealer spreads, taxes, stones, and buyback differences.

Standard formulaweight × purity ÷ 100 × pure-gold price

Worked example

10 g at 75% purity contains 7.5 g of fine gold. At $75 per gram, the estimated metal value is $562.50.

Frequently Asked Questions

How do I convert karat to purity?

Divide the karat by 24 and multiply by 100. For example, 18K is 75%.

Does this include jewelry making charges?

No. The result is the estimated value of the gold content only.

Can I use any currency?

Yes. Enter the weight and price in consistent units; the output uses the price currency.

Is the price live?

No. Enter a current reference price yourself.
