Scrap Value Calculator

Selling old gold can feel like guesswork. You hand over a box of jewelry and hope the offer is fair. The Scrap Value Calculator removes that uncertainty. It turns weight, purity, and the daily gold price into a clear net figure in seconds.

This guide explains how scrap gold is valued. You will learn what an assay fee is and why refiners charge it. You will also see two fully worked examples with real numbers. By the end, you will know exactly what your scrap is worth before you walk into a shop.

What Scrap Gold Value Means

Scrap value is the raw worth of the gold in your items. It ignores design, brand, and sentiment. Only metal content matters. A broken chain and a fine necklace hold the same value if they weigh the same and share the same purity.

Refiners calculate melt value first. Melt value equals weight times purity times the gold price. Purity is expressed as a fraction of 24. For example, 14k gold is 14 parts gold out of 24. That fraction is about 0.583.

From melt value, refiners subtract their costs. These include the assay fee, refining charges, and their profit margin. What remains is your payout. Knowing the melt value yourself puts you in a stronger position to judge any offer.

Gold prices move every day. A quote from last month may be far off today. Always use the current price per gram when you calculate. The calculator above uses the price you enter, so the result reflects today.

How Assay Fees Affect Your Payout

An assay is a test of your gold’s purity. Refiners must confirm the karat before they pay. Many charge a flat fee for this test. Typical fees range from $15 to $50 per lot.

The fee matters most on small lots. A $25 fee on $200 of gold takes 12.5 percent. The same fee on $2,000 takes just 1.25 percent. Small sellers feel assay fees the hardest.

Some buyers waive the fee for larger lots. Others fold it into a lower payout rate instead of charging it separately. Always ask how the fee is applied. A quote without a stated fee may hide the charge inside the price.

The calculator subtracts the fee from melt value. If fees exceed the melt value, it warns you instead of showing a negative number. That situation is rare but possible with tiny lots and high fees.

How to Use the Scrap Value Calculator

Follow these steps to get your estimate. The whole process takes under a minute.

1. Weigh your gold in grams. A kitchen scale works fine for this step.
2. Choose the karat from the dropdown. Check the stamp inside your jewelry.
3. Enter today’s gold price per gram in dollars.
4. Enter the assay fee your buyer charges. Use 25 as a typical default.
5. Press Calculate to see your estimated net scrap value.
6. Press Reset to clear the form and start over.

Worked Example 1: 50 Grams of 14k Gold

Inputs

You have 50 grams of 14k gold jewelry. Today’s price is $80 per gram. The buyer charges a $25 assay fee.

Calculation

First, find the purity fraction. Divide 14 by 24 to get 0.5833. Multiply 50 grams by 0.5833. The result is 29.1667 grams of pure gold.

Next, multiply 29.1667 grams by $80 per gram. The melt value is $2,333.33. Finally, subtract the $25 assay fee. The net scrap value is $2,308.33.

Result

The calculator shows an estimated net scrap value of $2,308.33. You can compare this figure against any offer you receive. A fair offer should land close to this number.

Worked Example 2: 100 Grams of 18k Gold

Inputs

You have 100 grams of 18k gold. Today’s price is $85 per gram. The assay fee is $25.

Calculation

Divide 18 by 24 to get a purity fraction of 0.75. Multiply 100 grams by 0.75. You get 75 grams of pure gold.

Multiply 75 grams by $85 per gram. The melt value is $6,375.00. Subtract the $25 assay fee. The net scrap value is $6,350.00.

Result

The calculator shows $6,350.00. Notice how the fee barely dents a large lot. Fees hurt small lots far more than big ones.

Why Purity Changes Everything

Karat measures how much of the metal is pure gold. A 24k item is pure gold. An 18k item is 75 percent gold. A 14k item is about 58.3 percent gold. The rest is alloy metal like copper or silver.

Many people overestimate their gold’s value. They weigh the whole piece and multiply by the full gold price. That ignores the alloy content. A 14k ring holds barely more than half its weight in gold.

Look for karat stamps on your items. Common marks include 10k, 14k, 18k, 585, and 750. The number 585 means 58.5 percent gold, which matches 14k. The number 750 means 75 percent, which matches 18k.

Unmarked items need testing. Acid test kits are cheap and widely available. Professional X-ray testing is more accurate. Never guess the karat when real money is at stake.

Common Deductions Beyond the Assay Fee

Assay fees are only one deduction. Refiners also charge for the refining process itself. Melting and purifying gold costs money. This charge is often built into the payout percentage.

Stones and non-gold parts add another wrinkle. Diamonds and gems are removed before weighing. Their weight should not count toward your gold total. Ask the buyer to weigh items with stones removed.

Some buyers pay only a percentage of melt value. Payouts of 80 to 95 percent are common. The calculator shows full melt value minus the assay fee. Treat that figure as the ceiling, not the guaranteed offer.

Shipping and insurance can apply for mail-in services. These costs eat into small lots quickly. Local buyers avoid shipping costs entirely. Compare both options before you decide.

Tips for Getting the Best Scrap Price

Use these tips to protect yourself and maximize your payout.

1. Weigh everything at home first. Walk in knowing your numbers.
2. Sort items by karat. Mixed lots often get priced at the lowest karat.
3. Get three written quotes. Competition raises offers.
4. Check the daily gold price before you sell. Timing matters.
5. Ask exactly how the assay fee is charged. Get it in writing.
6. Remove stones yourself when possible. Keep them for separate sale.

How Refiners Actually Process Your Gold

Your gold takes a long journey after you sell it. First, the refiner sorts items by karat. Each karat group is melted separately. Mixing purities would contaminate the batch.

The melted metal is then sampled and assayed. Fire assay remains the gold standard for accuracy. A small sample is melted with lead and analyzed. This confirms the exact gold content.

Next comes the actual refining. Chemical processes separate gold from alloy metals. The result is pure gold bars or grain. These are sold to manufacturers or investors.

Each step costs money. Energy, chemicals, and labor all add up. The assay fee you pay covers only the testing step. Refining costs are usually taken from the payout percentage.

Understanding this process helps you negotiate. You now know why buyers cannot pay full melt value. Their costs are real. But you also know how to spot an unfairly low offer.

Understanding Karat Stamps and Marks

Jewelry usually carries a small stamp showing its karat. Look inside rings and on clasps. A magnifying glass helps with tiny marks.

Common stamps include 10k, 14k, and 18k. European items may show 585 or 750 instead. These numbers mean parts per thousand. So 585 equals 58.5 percent gold.

Some items are only gold-plated. Stamps like GP, EP, or RGP signal plating. Plated items hold almost no scrap value. Do not include them in your calculation.

Vermeil means gold over sterling silver. It also holds little scrap value. Solid gold is what refiners want. When in doubt, have the item tested professionally.

Old or handmade pieces may lack stamps entirely. A jeweler can test them quickly. Many offer free basic testing. Use this service before you assume a karat.

When Selling Scrap Gold Makes Sense

Broken jewelry is the clearest case for selling. A snapped chain has no wear value left. Its only worth is the metal. Selling turns clutter into cash.

Outdated styles are another good candidate. Tastes change over decades. That heavy 1980s bracelet may never come back. Its gold content still holds value today.

Single earrings and odd pieces pile up in drawers. They serve no purpose sitting there. Combine them into one lot to spread the assay fee. The calculator shows why bigger lots get better net rates.

High gold prices create selling opportunities. Check the price trend over several months. If it sits near recent highs, selling locks in gains. You can always buy gold again later.

Keep pieces with strong sentimental value. No calculator measures memories. Sell only what you are ready to part with. Financial sense and feelings both matter here.

How Gold Prices Are Quoted

The gold spot price is quoted per troy ounce. A troy ounce equals 31.1035 grams. This differs from the regular ounce used in cooking. Always use troy ounces for gold math.

To get the price per gram, divide the spot price by 31.1035. If spot is $2,600, the gram price is about $83.59. The calculator needs the gram price, so do this conversion first.

Prices change throughout the trading day. Weekends and holidays freeze the quote. Use the most recent available price. A few dollars of movement is normal.

Retail buyers often quote below spot. They need room for costs and profit. The gap between spot and their price is called the spread. Smaller spreads favor the seller.

Track the price for a week before selling. Free charts are available online. Selling into strength beats selling into weakness. Timing is one of the few things you control.

Paperwork and Records to Keep

Keep a record of every gold sale. Note the date, weight, karat, and price received. Photos of the items help too. Good records protect you at tax time.

Ask for a written receipt from the buyer. It should list the weight and price per gram. Verbal deals leave you with no proof. Paper trails matter if disputes arise.

Compare the receipt against your calculator estimate. Large gaps deserve questions. An honest buyer will explain each deduction. Walk away from anyone who will not.

Store receipts with your tax documents. Gold sales may create taxable gains. Your cost basis is what you originally paid. The difference is your gain or loss.

Digital copies work as well as paper. Snap a photo of each receipt. Back it up somewhere safe. Years later, you will be glad you did.

Red Flags to Watch For

Some buyers use pressure tactics. They claim the price will drop tomorrow. They rush you to decide now. Honest buyers give you time to think.

Watch for vague weighing practices. The scale should be visible to you. Ask to see the reading yourself. Refusal is a clear warning sign.

Beware of buyers who will not explain deductions. Every charge should be itemized. Mystery fees mean mystery profits for them. Walk away from unclear deals.

Check reviews before visiting a new buyer. Look for patterns of complaints. One bad review means little. Dozens of them mean a lot.

Frequently Asked Questions

General Questions

1. What does the Scrap Value Calculator do?

It estimates the net value of your scrap gold. Enter weight, karat, price per gram, and assay fee. The tool subtracts the fee from melt value and shows the result instantly.

2. What is an assay fee?

An assay fee pays for purity testing. Refiners test your gold to confirm its karat. Fees usually run $15 to $50 per lot. Larger lots often qualify for waived fees. Ask about the fee policy before you commit to a buyer.

3. Is melt value the same as what I will receive?

No, melt value is the starting point. Buyers subtract fees and their margin. Your actual payout will be lower. Use the calculator result as a fair upper bound. Anything far below it deserves a second opinion.

4. How do I find today’s gold price per gram?

Search for the current gold spot price. It is quoted per troy ounce. Divide by 31.1035 to get the price per gram. Enter that figure in the calculator. Many price websites show both ounce and gram prices directly.

5. Can I use this for silver or platinum?

No, this tool is built for gold only. Silver and platinum have different prices and purity scales. Use a dedicated calculator for those metals.

How the Calculation Works

6. How is purity converted to a number?

Divide the karat by 24. For 14k, that gives 0.5833. Multiply your weight by this fraction. The result is the pure gold content in grams. This single step is where most beginners go wrong.

7. Why does the calculator show an error sometimes?

It warns you when fees exceed melt value. This happens with tiny lots and high fees. Selling such a lot may not be worth it. Consider combining it with more gold. A bigger lot spreads the fixed fee over more value.

8. What if my items have different karats?

Calculate each karat group separately. Add the results together. Mixing karats in one calculation gives a wrong answer. Sort before you weigh.

9. Should stones be included in the weight?

No, remove stones before weighing. Only metal counts toward scrap value. A heavy gem can inflate the weight and mislead you. Weigh metal only. Keep the stones to sell separately if they have value.

10. Does the calculator account for the buyer’s margin?

No, it shows melt value minus the assay fee. Real buyers pay less than this figure. Expect offers at 80 to 95 percent of melt value. Use the result as your benchmark.

Practical Questions

11. Is it better to sell locally or by mail?

Local buyers pay faster and avoid shipping risk. Mail-in services sometimes offer higher rates. Compare the net payout after all fees. Choose whichever leaves more in your pocket. Read reviews before mailing anything valuable.

12. Do I need an appointment to sell scrap gold?

Most local buyers accept walk-ins. Larger lots may deserve an appointment. Call ahead if you have many items. It saves time for everyone.

13. What identification do I need to sell gold?

Most places require a government photo ID. Some states record the transaction by law. Bring your ID to avoid delays. This is normal practice and protects both sides.

14. Are scrap gold sales taxed?

They can be, depending on your location and profit. Gold is often treated as a collectible for tax purposes. Keep your records. Talk to a tax professional for advice.

15. When is the best time to sell scrap gold?

Sell when the gold price is high relative to recent history. Watch the trend over weeks, not hours. Avoid panic selling during sharp dips. Patience usually pays. Set a target price and sell when it arrives.

CONCLUSION

The Scrap Value Calculator gives you the knowledge to sell with confidence. Enter your weight, karat, price, and fee to see your net figure. Compare that number against every offer you receive. A few minutes of math can save you hundreds of dollars.
