Frequently Asked Questions

How do gold calculators work?
Gold calculators use the current spot price (price per troy ounce) and your gold's weight and purity (karat) to calculate its melt value. The formula is: Weight × Purity Fraction × Spot Price Per Gram. This gives you the intrinsic metal value of your gold.
What gold price do you use?
Our calculators use the posted spot-price input shown on the page. The current figure displayed is $5,019.18 per troy ounce, timestamped Mar 15, 2026, 5:57 PM UTC. Prices may be delayed from live market trading.
Are these calculators free?
Yes, all GoldToolkit calculators are completely free to use. No signup, no account, and no personal data collection. We use privacy-respecting analytics with no tracking cookies.
How accurate is the melt value calculation?
The melt value calculation is mathematically precise using the standard industry formula. The main variable is the spot price, which fluctuates during market hours. The melt value represents the raw gold content value — actual buy/sell prices from dealers will differ.
What's the difference between melt value and what a dealer will pay?
Melt value is the theoretical worth of the gold content alone. The payout ranges shown on this site are rough estimates for context, not guaranteed rates. Actual offers vary by buyer type, lot size, and market conditions — and can fall well outside any single range.
Which calculator should I use?
Use the Gold Calculator for a single item. Use the Scrap Gold Calculator if you have multiple items. Use Gold Price Per Gram to quickly look up prices across all karats. Use the Purity Converter to decode hallmark stamps.
