Calculation assumptions
- *Gold value is estimated from the entered spot price per troy ounce and the selected purity.
- *The calculator does not fetch live gold prices; use the spot price basis you want to compare.
- *Jewellery prices can be higher than raw gold value because of making charges and tax/VAT.
- *Dealer spreads, refining fees, taxes, shipping, assay differences, market movement, and buyer rules are not included unless you enter them separately.
Estimate gold value by weight and purity
This gold calculator converts your entered weight into pure gold content using the selected karat, then values that pure gold using the spot price you provide. It is useful for comparing 24K, 22K, 18K, 14K, and 10K items at the same weight.
Example: 10 g of 22K gold contains about 9.17 g of pure gold. If your entered spot price is $2,300 per troy ounce, the estimated raw gold value is about $677.93.
Gold value vs jewellery price
Raw gold value reflects only the precious-metal content. Jewellery prices can be higher because retailers may add making charges, design labour, taxes, and local premiums on top of the underlying gold value.
Assumptions and common mistakes
This is not an appraisal and does not guarantee a resale offer. It uses the spot price you enter, not a live market feed.
- Do not mix regular ounces with troy ounces; gold spot prices use troy ounces.
- Do not value the full item weight as pure gold unless it is 24K.
- Remember that stones, non-gold parts, buyer spread, refining fees, and taxes can change real value.
- Market prices can move quickly, so update the entered spot price when comparing estimates.

Frequently Asked Questions
Common questions about Gold Calculator and how to read the result.
Why does 24K show a much higher value than 14K at the same weight?
Because the calculator values only the pure-gold portion of the item. 24K is nearly pure gold, while 14K is only 58.33% gold by content.
Is the jewellery estimate a final store price?
No. It is a planning estimate based on the raw gold value plus the making charges and tax/VAT percentages you enter. Real store prices can vary by brand, design, and local market.
Does this calculator use live gold prices?
No. Enter the spot price basis you want to use. The calculator does not fetch live market prices.
Is this an appraisal?
No. It estimates metal value from your inputs and should not be treated as an appraisal, resale quote, or investment advice.
Why does karat matter?
Karat controls purity. For example, 18K gold is about 75% gold, so only that share of the item weight is valued as pure gold.
What costs are excluded?
Dealer spreads, refining fees, assay differences, shipping, taxes, stones, non-gold parts, and buyer rules are not included unless you model them separately.
