Frequently Asked Questions
How accurate is this gold calculator?▼
The calculator uses the live COMEX spot price updated every 5 minutes. The result is the melt value — what the gold content is worth at spot. Dealers will pay 5–15% below melt value when buying from you, and sell at 3–8% above spot.
What is the difference between karat and carat?▼
In the context of gold, "karat" (K) measures purity — 24K is pure gold. "Carat" (ct) is a unit of weight used for gemstones (1 carat = 0.2 grams). They are completely different measurements. The UK sometimes uses "carat" for gold purity as well.
How do I find out my gold's karat?▼
Look for a hallmark stamped on the piece — common marks include "999", "916", "750", "585", or "375". Jewelry bought in the Middle East or South Asia is usually 22K (916). European jewelry is typically 18K (750). If unsure, a jeweler can test it with acid or XRF equipment.
What is the gold price today (2026)?▼
The current gold spot price is $4,160.3 per troy ounce, or $133.76 per gram for 24K pure gold.
Does the gold calculator include dealer premiums?▼
No — this calculator shows the melt value (spot price × weight × purity). When buying physical gold, dealers add a premium of 3–8% on coins and 1–3% on bars. When selling, you'll typically receive 85–95% of spot. Use the melt value as a baseline for negotiations.
