Gold Calculators
Gold calculators for scrap, melt, karat, grams, DWT, coins, or dental — pick the right tool, then run weight and purity math that matches what you hold.
Wrong tool, clean scale, bad number. Scrap, coins, dental, and gold-filled each need different inputs — and a generic "gold worth" path won't save a mis-sorted lot.
Use this directory like a bench cheat sheet: open the calculator that matches the metal and unit in your hand, then run melt-style math you can defend.
Start with what you're holding
Solid karat jewelry → karat page or scrap/melt tools.
Bullion and coins → ounce/coin melt paths.
Dental → dental tool with honest purity.
Gold-filled → filled fraction math, not solid karat.
Mixed gold + silver → dual-metal calculator.
Then match the scale: grams, DWT, or troy ounces. Last — decide if you're comparing melt, a cash offer, or jewelry resale. Those are three conversations.

Shared formula (every serious estimate)
Value ≈ weight × purity × gold price on the same unit basis.
Purity ≈ karat ÷ 24 for solid gold.
Offers often sit below full melt after testing, refining, and margin. Practice with illustrative spots; use live prices when cash is real.
EXAMPLE — picking the tool in 30 seconds
You have a broken 14K chain on a gram scale and a buyer talking DWT rates.
- Weigh grams → gold gram calculator or 14K gold calculator.
- Convert if the ticket is DWT → gold pennyweight calculator.
- Compare their cash to melt → cash for gold calculator.
Same metal, three jobs. Don't force one URL to do all three poorly.

Frequently Asked Questions
Which calculator should I use for mixed scrap?
Sort by karat first, then scrap gold calculator or each karat page. Mixed averages hide value.
What's the difference between melt and cash-for-gold tools?
Melt estimates intrinsic metal. Cash-for-gold framing compares offers and selling paths against that baseline.
Do I need a different tool for coins?
Yes for premium questions — start with gold coin melt calculator for the metal floor, then check collector value separately.
Grams or DWT — which hub link?
Match your scale and ticket. Both unit calculators are listed above; neither is "more correct."
Can one calculator replace this whole list?
A flexible melt tool covers custom purity. Karat- and material-specific pages cut mistakes when stamps and categories differ.
Are these payout guarantees?
No. They're educational melt-style estimates. Settlement follows assay and buyer terms.
Disclaimer
Pick the tool that matches your material. Wrong purity or unit inputs produce confident garbage. Educational use only.
