Gold Price Per Gram Today
The gold price per gram today changes constantly with global markets. Here's how to find it, calculate it by karat, and use it to make smarter buying and selling decisions.
What is the gold price per gram today?
The gold price per gram today is derived from the live spot price of gold, which trades globally in troy ounces and fluctuates throughout the trading day. To get the price per gram, divide the current spot price by 31.1035 — the number of grams in one troy ounce.
For live spot prices, check Kitco.com — the most widely used source among professional gold buyers.
Quick formula: Spot price ÷ 31.1035 = gold price per gram today (for pure 24K gold). Adjust for karat from there.
Gold price per gram by karat
Not all gold is 100% pure. The karat stamp tells you the purity — and purity directly determines value. Here's how the gold price per gram breaks down across common karats, using a $3,000/oz spot price as an example:
| Karat | Purity | % of spot | Price per gram* |
|---|---|---|---|
| 24K | 99.9% pure | 100% | ~$96.50 |
| 22K | 91.7% pure | 91.7% | ~$88.49 |
| 18K | 75.0% pure | 75.0% | ~$72.37 |
| 14K | 58.3% pure | 58.3% | ~$56.25 |
| 10K | 41.7% pure | 41.7% | ~$40.23 |
*Based on $3,000/oz spot price example. Always use the current live price.
How to calculate gold value step by step
Professional gold buyers use this exact formula on every deal. Once you have the gold price per gram for the right karat, the rest is straightforward:
15 × 0.583 × 96.50 = $844.25 melt value
Step-by-step calculation
- 1Get the current gold spot price per troy ounce from Kitco.com
- 2Divide by 31.1035 to get the price per gram for pure 24K gold
- 3Multiply by the karat purity percentage (14K = 0.583, 18K = 0.75, etc.)
- 4Multiply by the weight in grams
- 5The result is melt value — what the gold is theoretically worth at 100%

Melt value is the ceiling — not what you'll receive when selling, and not what you should pay when buying. Gold buyers factor in refining costs, profit margin, and risk. Here's the typical range:
If you're buying gold to resell, your profit comes from the spread between what you pay and melt value. Most experienced buyers target 70% of melt or below to leave room for testing costs, refining, and margin.

How to use gold price per gram to profit as a buyer
Knowing the gold price per gram is only half the equation. The other half is knowing what to pay. Here's the framework professional buyers use:
- Calculate melt value first — before you make any offer
- Target 70% of melt value or below as your offer price
- Know your buyer — have a refiners or resale outlet lined up before you buy
- Factor in testing costs — acid kits, scale calibration, and time
- Never negotiate without a number in your head
The gold price per gram gives you the anchor for every negotiation. Sellers rarely know it. When you do, you have the advantage.
