Gold Value Calculator - Price by Weight & Karat | 1Dollars

Free Gold Value Calculator

Calculate how much gold is worth using its weight, purity and the current gold price you enter. The calculator supports common global weight units and currency codes, then estimates pure-gold content, metal value and a possible dealer payout.

Gold Value Calculator

Enter the gold item, its purity and a current market price. You can use a 24K, 22K, 18K or 14K quoted rate without changing currencies.

Enter a current retail, bullion or reference price in the selected currency.
Use 100% for metal value, or enter the buyer's quoted payout percentage.

This calculator does not fetch or redistribute a live benchmark price. Enter a current price you are permitted to use. Results exclude gemstones, making charges, collectible value, taxes and fees unless reflected in your entered rate or payout percentage.

Reviewed on 15 July 2026 using Bureau of Indian Standards hallmarking guidance, World Gold Council purity and weight information, and LBMA benchmark documentation.

Gold value is primarily determined by the item's weight, gold purity and an appropriate price for the same market and currency. This calculator also accounts for cases where the entered price is quoted for a different purity than the item—for example, valuing 18K jewelry from a 24K or 22K market rate.

Quick answer: Select the item's weight and purity, enter a current gold price with its unit and quoted purity, choose the currency code, and calculate. Use the dealer payout field only when you want to estimate an offer below the calculated metal value.

How the Gold Value Calculator Works

The calculator first converts the entered weight to grams. It then converts the quoted gold price to a per-gram rate and adjusts that rate to an estimated pure-gold basis. Finally, it applies the item's purity and any dealer payout percentage.

Estimated gold value = weight in grams × pure-gold price per gram × item purity percentage

When the entered price is already quoted for the same purity as the item, the purity conversion cancels out and the result is essentially the quoted price per unit multiplied by the item's equivalent weight.

Fineness expresses precious-metal content in parts per thousand. Actual accepted marks, tolerances and minimum grades vary by country. BIS guidance for India includes hallmarking grades such as 14K585, 18K750, 20K833, 22K916, 23K958 and 24K995.

Supported Gold Weight Units

Grams and kilogramsThe calculator uses 1 kilogram = 1,000 grams.
Troy ouncesOne troy ounce is converted as 31.1034768 grams.
TolaThe tool uses approximately 11.6638038 grams per tola.
Pennyweight and grainsOne pennyweight is 1/20 troy ounce; one troy grain is 1/480 troy ounce.

Gold Value vs Melt Value vs Resale Value

  • Gold metal value: an estimate based on recoverable gold content and the price entered.
  • Melt value: intrinsic gold value before refining, assay and handling deductions.
  • Dealer payout: the estimated amount after applying the payout percentage entered.
  • Jewelry resale value: may include or exclude design, brand, condition, gemstones and local demand.

A jewelry invoice can be higher than metal value because it may include making charges, wastage, retailer margin, taxes, certification or gemstones. A scrap or exchange offer can be lower because the buyer may deduct assay, refining, administrative and risk costs.

How to Estimate a Dealer's Gold Payout

Ask the buyer for its payout percentage or compare the quoted offer with your estimated metal value. If the buyer offers 90% of calculated metal value, enter 90 in the payout field. The difference shown by the tool is only a mathematical deduction and does not explain every fee.

Dealer payout percentage = dealer offer ÷ estimated metal value × 100
Use a current price: gold prices can change throughout the day and may differ by location, currency, product and retail market. This tool deliberately asks you to enter a price instead of displaying an unlicensed or delayed benchmark feed.

Frequently Asked Questions

How do I calculate the value of my gold?
Convert the item's weight to the same unit as the gold price, adjust for purity, and multiply. This calculator performs the unit and purity conversions automatically.
Can I calculate 22K gold value from a 24K price?
Yes. Select the item's purity as 22K / 916 and the entered-price purity as 24K / 999. The calculator converts the quoted rate to a pure-gold basis before valuing the 22K item.
Can I use a 22K market price directly?
Yes. Choose 22K / 916 under “Purity used by the entered price.” If the item is also 22K, the result follows the entered 22K rate after unit conversion.
Does the calculator show a live gold price?
No. Enter a current price from a source you are permitted to use. This avoids presenting a delayed or unlicensed benchmark as a live transactional rate.
What is one troy ounce of gold in grams?
The calculator uses 31.1034768 grams for one troy ounce, consistent with World Gold Council weight information.
What does 916 mean on gold?
A 916 fineness mark represents approximately 916 parts gold per thousand, or 91.6% gold. It is commonly associated with 22K gold.
Why is the dealer payout lower than gold value?
A buyer may apply deductions for refining, assay, handling, business margin or market risk. Enter the quoted payout percentage to estimate the offer, then request a written breakdown from the buyer.
Does gold weight include gemstones?
The entered weight should represent gold or gold-alloy weight. Gemstones, enamel, springs and non-gold components can overstate gold value if included.
Can this calculator value gold coins and bars?
It can estimate their metal value. A coin or bar may trade above or below metal value because of bullion premium, brand, certification, condition, rarity and dealer spread.
Is the calculated gold value guaranteed?
No. It is an estimate based on your inputs. Actual purity testing, scale accuracy, market price, taxes, fees and the buyer's terms may produce a different result.
