Formula Used
Weight in grams = Entered weight × unit conversion factor.
Gross troy ounces = Weight in grams ÷ 31.1034768.
Purity factor = Karat ÷ 24, percent ÷ 100, or fineness ÷ 1000.
Pure troy ounces = Gross troy ounces × purity factor.
Melt value = Pure troy ounces × spot price.
Premium value = Melt value × premium percent.
Adjusted value = Melt value + premium value.
Refined value = Adjusted value × (1 − refining loss percent).
Estimated cash offer = Refined value × dealer payout percent − total fees.
Spread = Adjusted value − estimated cash offer.

Tulsa Gold And Silver Value Guide
A local metal quote can change fast because spot prices move all day. This calculator gives a structured way to estimate gold, silver, or custom alloy value before you visit a shop. It uses weight, purity, spot price, refining loss, payout rate, and fees. The result is not a guaranteed offer. It is a careful estimate for comparison. That matters when jewelry contains stones, solder, plating, or mixed metals.
Why Purity Matters
Chemistry affects every metal valuation. Pure gold is twenty four karat, but most jewelry is alloyed for strength. Ten karat, fourteen karat, and eighteen karat pieces contain different fractions of gold. Silver works in a similar way. Sterling silver is usually 92.5 percent silver. Coin silver and fine silver have different fineness values. The calculator converts purity into a decimal fraction. Then it multiplies that fraction by the converted metal weight.
Using Local Offer Inputs
Tulsa buyers may quote different payout rates. One shop may pay close to melt for clean bullion. Another may pay less for scrap jewelry because refining, sorting, and testing cost money. Enter the dealer payout rate to model that difference. Add refining loss if the item has wear, solder, enamel, stones, or uncertain purity. Add flat fees only when they apply. Keeping each deduction visible helps you judge whether an offer is fair.
Reading The Result
The melt value shows the estimated value of the pure precious metal. The refined value shows melt value after loss. The estimated payout shows the amount after dealer percentage and fees. The spread shows the gap between melt value and the expected cash offer. A large spread is not always wrong, but it should be understood. Use the example table to compare common items. Update spot prices before each calculation.
Safe Testing Notes
Use honest purity data whenever possible. Hallmarks can be wrong, damaged, or missing. Acid tests, density checks, and XRF readings may improve confidence. Still, final buyer testing controls the quote. Remove nonmetal weight when practical. Weigh stones and findings separately if known. Record each assumption beside the result. Clear notes make negotiation easier and reduce mistakes. Compare at least two offers when values appear unusually different locally.
FAQs
What does this calculator estimate?
It estimates melt value, refined value, dealer payout, fees, and final cash offer. It helps compare Tulsa gold and silver quotes before selling.
Is the result a guaranteed dealer offer?
No. The result is an estimate. Dealers may test purity, remove stones, apply fees, or change payout rates after inspection.
Which spot price should I enter?
Enter the current market price per troy ounce for your metal. Use gold spot for gold and silver spot for silver.
How do I enter 14k gold?
Select karat as the purity type. Enter 14 as the purity value. The calculator converts it into a gold fraction.
How do I enter sterling silver?
Select fineness as the purity type. Enter 925 as the purity value. Sterling silver is commonly valued as 92.5 percent silver.
What is refining loss?
Refining loss estimates value reduction from solder, wear, stones, mixed metals, or uncertain purity. It lowers the adjusted value.
Why is dealer payout below melt value?
Dealers often deduct refining costs, testing costs, business margin, and market risk. The payout percent models that difference.
