About Gold Calculator
About Us
Gold Calculator is a free, independent tool for estimating gold value by weight, purity, and live market price — built for people checking an offer, not selling to them.
Our Mission
Most people selling gold have no quick way to know whether an offer is fair. Buyers know the melt value of your items to the cent; sellers usually do not. Our mission is to close that gap with a calculator anyone can use in under a minute.
We are deliberately not a gold buyer, dealer, or broker. We earn nothing from the number you see, so the estimate has no reason to lean high to attract you or low to buy your gold cheaply. That independence is the point of the site.
Every calculation is transparent: the live price, its timestamp, the karat purity ratio, and the payout percentage are shown next to the result, and the full formula is documented on our Methodology page so any estimate can be verified by hand.
Simplicity
Enter weight, choose purity, select currency, and see the estimated value without complicated steps.
Useful Context
Results explain gold price per gram, pure-gold weight, and why buyer offers can differ — including realistic payout ranges.
Privacy Friendly
Calculator inputs run in your browser and do not require an account, sign-up, or email.
