If you’re checking the 18K gold price today per gram, the key number depends on the current price of pure gold and the fact that 18K gold is 75% pure.
As a current reference for September 24, 2026, live gold-price sources are showing 18K gold at roughly $102–$103 per gram in USD. The exact figure can change throughout the day because gold trades continuously, and different data providers can show slightly different prices depending on the market feed and update time.
For a theoretical 18K gold value, the basic calculation is:
18K gold value per gram = 24K gold price per gram × 0.75
That calculation gives you an estimate of the gold content value. It is not necessarily the amount a jeweler, refinery, pawn shop, or gold buyer will pay for a finished item.
What Is the 18K Gold Price Per Gram Today?
The 18K gold price per gram is approximately $102–$103 per gram in USD based on live market references checked on September 24, 2026.
Because gold prices change throughout the day, there is no single permanent 18K gold price. A live reference can move by the minute as the underlying 24K gold market changes.
| Gold purity | Approx. purity | Reference value per gram* |
|---|---|---|
| 24K | 99.9% | About $136.80 |
| 22K | 91.7% | About $125.48 |
| 18K | 75% | About $102.60 |
| 14K | 58.3% | About $80.03 |
| 10K | 41.7% | About $57.04 |
*Reference figures based on a September 24, 2026 market snapshot. Prices vary by data provider, timestamp, currency conversion and market conditions.
A separate live 18K source reported approximately $102.43 per gram in the United States, illustrating why small differences between live feeds are normal.
The important point is that 18K gold is worth 75% of the equivalent 24K gold price by weight, before considering premiums, discounts, jewelry value, refining costs or buyer margins.
How Much Is 18K Gold Worth Per Gram?
The theoretical value of one gram of 18K gold is calculated by taking the current pure-gold price per gram and multiplying it by 0.75.
For example, if 24K gold is $136.80 per gram:
$136.80 × 0.75 = $102.60
So the theoretical 18K gold value would be $102.60 per gram at that reference price.
This is the value of the gold content based on the market price. It should not automatically be interpreted as the resale price of a ring, necklace, bracelet or other jewelry.
For comparison, OfferBin’s guide to 14K gold worth per gram can help you see how a lower karat changes the calculation.
Why Is 18K Gold 75% Pure?
The “18K” designation refers to the number of parts of gold out of 24 parts in the alloy.
The calculation is:
18 ÷ 24 = 0.75
Then:
0.75 × 100 = 75%
So theoretically, 18K gold contains:
- 75% pure gold
- 25% other metals
The remaining metals are used to create an alloy with properties that can be useful for jewelry, such as increased hardness, durability or a particular color.
You may also see 750 stamped on 18K gold.
The 750 marking means 750 parts of gold per 1,000 parts of metal:
750 ÷ 1,000 = 75%
Therefore, 18K, 18KT and 750 commonly indicate the same basic gold purity standard.
What Is the 18K Gold Price Formula?
The simplest theoretical formula is:
18K gold value per gram = current 24K gold price per gram × 0.75
If the gold price is quoted per troy ounce instead of per gram, convert it first.
Step 1: Convert the Gold Price to Grams
One troy ounce contains approximately 31.1035 grams.
So:
24K gold price per gram = 24K gold price per troy ounce ÷ 31.1035
Step 2: Apply the 18K Purity Factor
Then:
18K gold price per gram = 24K gold price per gram × 0.75
For example, if pure gold were $4,255 per troy ounce:
$4,255 ÷ 31.1035 ≈ $136.80 per gram
Then:
$136.80 × 0.75 = $102.60
That gives an estimated 18K metal value of approximately $102.60 per gram.
Gold is normally quoted internationally using a troy ounce rather than the ordinary ounce used for everyday products, so using 28.35 grams for this conversion would produce the wrong result.
18K Gold Value by Weight
Once you know the approximate 18K value per gram, you can estimate the metal value of different weights.
Using $102.60 per gram as an illustrative reference:
| 18K gold weight | Approx. gold content | Estimated metal value |
|---|---|---|
| 1 gram | 0.75 g | $102.60 |
| 2 grams | 1.50 g | $205.20 |
| 5 grams | 3.75 g | $513.00 |
| 10 grams | 7.50 g | $1,026.00 |
| 20 grams | 15.00 g | $2,052.00 |
| 31.1035 grams | 23.3276 g | About $3,190 |
These are mathematical estimates based on the same reference price. They are not guaranteed selling prices.
If your jewelry contains stones, clasps, springs or other materials, you also need to consider whether the entire weight should be treated as 18K gold.
18K Gold Price Today in USD, PKR, GBP and EUR
The value of 18K gold can look very different when displayed in another currency, even though the underlying gold value is the same.
On September 24, 2026, available market references showed approximately:
| Currency | Approx. 18K value per gram |
|---|---|
| USD | $102–$103 |
| PKR | About Rs. 28,500 |
| GBP | About £77–£78 |
| EUR | About €90–€91 |
The exact currency value depends on the gold price and the exchange rate used at the time of calculation.
For example, a Pakistan-focused live reference reported approximately PKR 28,573 per gram for 18K gold, while another source showed approximately PKR 28,507 per gram at a different timestamp.
A UK reference showed approximately £77.60 per gram, while European data showed approximately €90.55 per gram on September 24, 2026.
These differences demonstrate why a “today” gold price should always be associated with a date, time and data source.
18K Gold Price in Pakistan Per Gram
For readers checking the 18K gold price today in Pakistan per gram, a September 24, 2026 market reference put the value around PKR 28,500 per gram.
The calculation is still based on the same purity relationship:
18K = 75% gold
The PKR price can change because of:
- International gold prices
- USD/PKR exchange rates
- Local market conditions
- Dealer premiums
- Jewelry-making charges
- Regional buying and selling prices
A quoted market value should therefore not be confused with the final retail price of an 18K jewelry item in Pakistan.
18K Gold Price Per Gram vs. 18K Jewelry Price
The 18K gold price per gram is not necessarily the same as the price you pay for 18K jewelry.
A jewelry item’s retail price can include:
- Gold content
- Labor
- Design
- Manufacturing costs
- Retail markup
- Brand premium
- Gemstones
- Taxes
- Shipping or other charges
For example, two 10-gram 18K rings can contain a similar amount of gold but have very different retail prices.
A simple gold-content calculation tells you about the underlying metal value. It does not provide a complete appraisal of a finished piece of jewelry.
Is 18K Gold Melt Value the Same as Its Selling Price?
No.
This is one of the most important distinctions when checking how much 18K gold is worth.
Melt value is an estimate based primarily on:
Weight × purity × current gold price
An actual buyer’s offer can be lower or otherwise different because the buyer may account for:
- Refining costs
- Testing costs
- Processing
- Operating expenses
- Dealer margins
- Market conditions
- Non-gold components
- Resale considerations
For example, if a 10-gram item is genuinely 18K and the reference metal value is $102.60 per gram:
10 × $102.60 = $1,026
That $1,026 represents a theoretical metal-value calculation. It does not mean every buyer will offer exactly $1,026.
The distinction is similar to the difference between a calculator estimate and an actual market transaction.
How Much Pure Gold Is in 1 Gram of 18K Gold?
One gram of theoretical 18K gold contains approximately:
1 × 0.75 = 0.75 grams of pure gold
So:
- 1g of 18K → 0.75g pure gold
- 2g of 18K → 1.50g pure gold
- 5g of 18K → 3.75g pure gold
- 10g of 18K → 7.50g pure gold
- 20g of 18K → 15.00g pure gold
The remaining 25% consists of other metals in the alloy.
This is why 18K gold has a higher theoretical metal value per gram than 14K gold, but a lower value per gram than 22K or 24K gold, assuming the same underlying market price.
18K Gold vs. 14K, 22K and 24K
Karat is a measure of gold purity.
| Gold type | Theoretical purity | Common fineness |
|---|---|---|
| 10K | 41.67% | 417 |
| 14K | 58.33% | 583/585 |
| 18K | 75% | 750 |
| 22K | 91.67% | 916/917 |
| 24K | Approximately 99.9% | 999 |
At the same weight and gold market price, a higher-purity alloy contains more gold.
18K vs. 14K Gold
18K gold contains 75% gold compared with approximately 58.33% for theoretical 14K gold.
Therefore, a one-gram 18K item contains more pure gold than a one-gram 14K item.
If you want to compare the calculations in more detail, see the 14K gold value guide for the formula and examples.
18K vs. 22K Gold
22K gold is approximately 91.67% gold, so it contains more gold per gram than 18K.
The theoretical purity factors are:
- 18K = 0.75
- 22K = 0.9167
Therefore, if the underlying pure-gold price is identical, 22K has a higher theoretical metal value per gram.
18K vs. 24K Gold
24K is used as the high-purity benchmark for many gold-price calculations.
18K contains approximately 75% of the gold content of an equivalent weight of pure 24K gold.
That is why the basic 18K calculation uses a 0.75 multiplier.
What Does 750 Mean on Gold?
750 is a fineness marking.
It means that out of 1,000 parts of the alloy, approximately 750 parts are gold.
So:
750 ÷ 1,000 = 75%
That corresponds to 18K gold.
You may find 750 markings on jewelry manufactured in or sold through various international markets.
Common related markings include:
- 585 → approximately 14K
- 750 → 18K
- 916/917 → approximately 22K
- 999 → approximately 24K
A stamp provides an indication of stated purity, but it should not automatically be treated as conclusive proof that an item is authentic.
How Do You Calculate the Value of 18K Gold?
Use this five-step process.
1. Determine the Weight
Measure the item in grams if possible.
A jewelry item’s total weight may include stones and other materials, so total weight is not always identical to gold-bearing weight.
2. Confirm the Purity
Look for markings such as:
- 18K
- 18KT
- 750
For valuable pieces, additional testing may be appropriate.
3. Find the Current 24K Gold Price
Make sure you know:
- Price per gram or troy ounce
- Currency
- Timestamp
- Data source
4. Apply the 75% Factor
If the price is already per gram:
18K price per gram = 24K price per gram × 0.75
5. Multiply by the Gold Weight
For a 10-gram theoretical 18K item:
10 × 24K price per gram × 0.75
This gives you an estimated metal value.
Common 18K Gold Valuation Mistakes
Using the full 24K price
One gram of 18K gold is not one gram of pure gold.
Applying the full 24K price directly to 18K jewelry will overstate its theoretical gold content.
Confusing troy ounces with regular ounces
Gold markets commonly use troy ounces.
One troy ounce is approximately 31.1035 grams.
Treating jewelry weight as pure gold weight
A piece can contain:
- Gemstones
- Diamonds
- Clasps
- Springs
- Solder
- Other metals
The entire item should not automatically be valued as 18K gold.
Assuming melt value equals buyer price
A theoretical melt calculation is a reference point, not a guaranteed offer.
Using an outdated price
Gold prices move continuously. A calculation made yesterday may not represent today’s market.
Ignoring currency conversion
An 18K gold price in USD will not be the same numerical figure as the price in PKR, GBP or EUR.
The underlying gold value can be equivalent while the displayed number changes because of exchange rates.
What Factors Affect the Value of 18K Jewelry?
The market value of the gold itself is only one part of the picture.
Weight
More gold-bearing weight generally means more contained gold when purity remains constant.
Purity
An 18K item contains more gold by weight than a comparable 14K item.
Current Gold Price
Because 18K value is derived from the underlying gold market, changes in the gold price affect its theoretical value.
Gemstones
Diamonds and other gemstones may add value that is not represented by a simple gold-melt calculation.
Brand and Design
Designer, vintage, antique or collectible jewelry may have value beyond the raw metal.
Condition
Condition can influence resale value, particularly when the item is being sold as finished jewelry rather than scrap.
Buyer Pricing
Different buyers can use different margins, costs and purchasing models.
This means two offers for the same piece can differ.
18K Gold Price Per Gram: Quick Calculation Examples
Assume a hypothetical 24K gold price of $136.80 per gram.
The 18K rate would be:
$136.80 × 0.75 = $102.60
Now calculate several weights:
2 grams
2 × $102.60 = $205.20
5 grams
5 × $102.60 = $513.00
10 grams
10 × $102.60 = $1,026.00
20 grams
20 × $102.60 = $2,052.00
Again, these figures represent theoretical metal value using the stated reference price. They are not guaranteed resale offers.
How Often Does the 18K Gold Price Change?
The underlying gold market can move throughout the trading day.
Live gold-price services therefore update their figures regularly, and different services can show slightly different values at the same time.
For example, current September 24, 2026 sources show 18K gold around the low-$102-per-gram range in USD, but the exact quoted value varies according to the timestamp and market feed.
For that reason, a page targeting 18K gold price today per gram should show a clear date/time or live-data timestamp rather than presenting one number as permanently accurate.
18K Gold Price vs. Gold Spot Price
Gold spot price normally refers to the market price of gold for a specified unit, commonly a troy ounce.
18K gold is an alloy containing approximately 75% gold.
Therefore, you can use the spot price as the starting point and adjust it for purity.
For example:
24K spot-equivalent price per gram × 0.75 = theoretical 18K value per gram
The spot price is not necessarily the same as:
- Jewelry retail price
- Scrap buyer offer
- Refinery payout
- Pawn-shop offer
- Finished jewelry resale value
Understanding this distinction prevents many valuation mistakes.

Does an 18K gold price calculator show what a buyer will pay?
Not necessarily. A calculator generally estimates theoretical metal or melt value. An actual buyer may deduct refining, testing, operating and other costs or value the jewelry differently.
Why does the 18K gold price change?
Because 18K gold value is linked to the underlying gold market. Gold prices change with market conditions, currencies, trading activity and other factors.
Can an 18K ring be worth more than its gold value?
Yes. A finished piece can potentially have additional value because of its design, brand, age, gemstones, craftsmanship or collectible characteristics.
Final Takeaway
The 18K gold price today per gram is based primarily on two things: the current price of pure gold and the 75% gold purity of 18K material.
The basic formula is simple:
18K gold value per gram = 24K gold price per gram × 0.75
As of September 24, 2026, current market references put the theoretical 18K value around $102–$103 per gram, with approximately PKR 28,500 per gram in Pakistan and roughly £77–£78 per gram in the UK. Exact values change throughout the day.
The most important distinction is between metal value and actual selling price. A calculator can estimate the gold content, but jewelry buyers, refiners and retailers may use different pricing models.
