Gold Calculator Pro works out the melt value of gold from its weight and purity, using live market data refreshed on a 5-minute interval. Enter the weight and karat, and it returns the estimated value immediately.
Purity coverage runs from 9K to 24K — 9K (37.5%), 10K (41.7%), 12K (50%), 14K (58.5%), 18K (75%), 21K (87.5%), 22K (91.6%), 24K (99.9%) — plus a custom percentage field for anything non-standard. Weight can be entered in grams, troy ounces, pennyweights (DWT), or tolas, with 1 tola fixed at 11.6638 grams.
The homepage also carries a full price table showing every karat against every weight unit at the current spot price, so you can read off a value without running a calculation at all.

Specialized Calculators
Dedicated pages cover 10K, 14K, 18K, 22K, and 24K gold; price per gram, per troy ounce, per pennyweight, and per tola; and item types including scrap gold, rings, chains, general jewelry, and a sell-gold calculator for negotiating with a buyer.
Who It’s For
Anyone selling scrap gold or old jewelry who wants a number before walking into a pawnshop, plus investors and professional buyers checking values against the current spot price.
How It Works
- Enter the weight and select the unit — grams, troy ounces, DWT, or tolas.
- Select the karat, or enter a custom purity percentage.
- Read the estimated melt value against the live spot price.
One caveat the site states directly: the figure is “for reference only. Actual buyback price varies.” Melt value is the metal content, not what a dealer will offer.
