What Is a Gold Calculator and Why Do You Need One?
A gold calculator is an easy-to-use online tool that shows how much your gold is worth. You simply enter the weight in grams and choose the purity, such as 9ct, 18ct, or 24ct. The calculator then uses the live market price of gold to give you an instant estimate in British pounds.
This gold estimator is helpful when you want to sell or buy gold. If you are selling old jewellery or scrap gold, the gold estimator gives you a fair idea of its value before visiting a buyer. If you are buying gold coins or jewellery, it helps you check if the asking price makes sense. You can also use it at home just to see what a gold ring, bangle, or necklace might be worth.
How to Manually estimate the Value of Your Gold
You can estimate the value of your gold at home using a simple method. You will need to know three things: the weight of your gold in grams, its purity, and the current gold price per gram.
- Weigh your gold: Weigh your gold in grams using a digital kitchen scale.
- Check Purity: Check the purity of the gold. Use the carat to find the percentage. For example:
- 24ct = 100% pure = 1.00
- 22ct = 91.6% pure = 0.916
- 18ct = 75% pure = 0.75
- 14ct = 58.5% pure = 0.585
- 9ct = 37.5% pure = 0.375
- Check Live Gold Price: Find the current live gold price per gram in British pounds.
- Use the formula: Use the following formula for calculating the price of your gold.
Estimated Gold Value = Weight × Purity × Gold Price per Gram
Example:
You have 10 grams of 18ct gold. The live gold price is £40 per gram.
10 × 0.75 × £40 = £300
So, your gold is worth approximately £300.

How is the Purity of a Gold Item Measured in the UK?
In the UK, gold purity is measured in carats. The higher the carat number, the purer the gold. 24 carat is considered pure gold, which means it contains almost 100 percent gold. Lower carat gold, such as 18ct or 9ct, is mixed with other metals like silver or copper to make it stronger and more durable for everyday use.
What is carat?
Carat is a unit that shows how much pure gold is present in a piece of jewellery or item.
Popular Gold Carats in UK
Carat | Gold Purity (%) |
24ct | 99.9% |
22ct | 91.6% |
18ct | 75.0% |
14ct | 58.5% |
9ct | 37.5% |
UK Hallmarking System
In the United Kingdom, gold items are tested and hallmarked by official Assay Offices. There are four Assay Offices: London, Birmingham, Sheffield, and Edinburgh. Each one uses a unique symbol as part of the hallmark.
A hallmark is a small set of stamped marks on the gold item. It confirms important details, including the metal type, its purity (for example, “750” for 18ct gold), and the Assay Office that tested it. In the UK, hallmarking is a legal requirement for gold items weighing over 1 gram.
These marks give buyers and sellers confidence by proving that the gold has been properly tested. When you see a hallmark, you know the item meets official UK standards for gold purity.
