Gold Tools
Four tools, each answering a different question. All of them are free, none of them needs an account, and every figure is computed in your browser: nothing you type is sent anywhere.
Gold unit converter
What is this quantity of gold worth?
Enter any amount, unit, karat and currency; see it expressed every other way at once. Grams, troy ounces, kilograms, tolas and pennyweights across ten currencies.
Open tool →A quick what-ifBasic investment calculator
What would my gold be worth now?
Pick an amount and how long ago you bought. See what it would be worth today, the gain, and the annual return. Two inputs, no setup.
Open tool →Modelling a purchase held over yearsAdvanced investment calculator
What if I bought every month?
Lump sum, monthly contributions, or both, from any date. Returns a money-weighted annual rate, an inflation-adjusted figure, and the effect of an annual holding cost.
Open tool →Selling old or broken jewelleryScrap value calculator
What will a dealer pay me?
Melt value from weight and karat, plus an adjustable dealer payout so you can sanity-check an offer against what the metal is actually worth.
Open tool →Which one do you need?
If you are holding a physical item and want to know what it is worth, start with the unit converter for its metal value, then the scrap calculator if you are actually planning to sell it: the gap between those two numbers is the dealer’s margin, and it is worth seeing explicitly.
If you are thinking about buying rather than selling, the basic or advanced investment calculator models what a purchase would have done historically. Before that, it is worth understanding the difference between holding metal, a fund and a bond, since the costs in the calculator depend heavily on which one you pick.
