How to Calculate 14k Gold Rate from 24k
Understanding gold purity pricing is essential whether you are buying jewelry, selling scrap gold, or investing in precious metals. The market price of gold is almost always quoted for 24k (24 Karat), which represents 99.9% pure gold. However, most durable jewelry is made from 14k gold. This guide explains exactly how to calculate the 14k gold rate from the standard 24k market rate.
The Mathematics Behind Gold Karats
The "Karat" system measures the proportion of pure gold in an alloy out of 24 parts. Therefore:
- 24k Gold: 24 parts gold (100% theoretical purity, effectively 99.9%).
- 14k Gold: 14 parts gold mixed with 10 parts of other metals (alloys like copper, silver, or zinc).
To convert the price, you need to determine the pure gold content percentage of 14k gold.
Percentage Formula: 14 ÷ 24 = 0.5833 (or 58.3%)
Step-by-Step Calculation Formula
To find the value of 14k gold based on the current 24k price, use the following simple formula:
14k Price = Current 24k Price × (14 / 24)
Example Calculation
Let's assume the current market rate for 24k gold is 6,000 per gram.
- Identify the 24k Rate: 6,000
- Divide by 24: 6,000 / 24 = 250 (This is the cost per single karat).
- Multiply by 14: 250 × 14 = 3,500.
So, if 24k is 6,000, the intrinsic value of 14k gold is 3,500 per gram.

Why is 14k Gold Popular?
While 24k gold is the most valuable, it is extremely soft and prone to scratching or bending. 14k gold is the standard for engagement rings and everyday jewelry because the additional alloy metals (the 10 parts that are not gold) add significant strength and durability. Furthermore, 14k gold is more affordable, costing approximately 58% of the price of pure gold.
Calculating Total Value with Weight and Making Charges
The calculator above also accounts for weight and "making charges." The raw formula gives you the melt value of the gold. However, if you are buying jewelry, the jeweler will add a making charge (labor fee) usually expressed as a percentage or a flat fee per gram.
Final Jewelry Price Formula:
((24k Rate × 0.583) × Weight in Grams) + Making Charges + Tax
