Silver Calculator — Check Melt, Scrap & Sterling Silver Value
How Much Is My Silver Worth?
Every method of valuing silver comes down to the same three numbers: how much it weighs, how pure it is, and today’s silver spot price. The tool above covers four common situations – a general weight-based calculation, sterling silver specifically, a realistic scrap payout estimate, and a simple ounces-times-price lookup. Below, each one is explained in more depth, along with the real-world details (like what dealers actually pay versus theoretical melt value) that most calculators leave out.
1. Silver Value by Weight & Purity
This is the core calculation behind every silver valuation: multiply the weight by the purity (as a decimal) and by the spot price. It works for any purity level, which makes it the right choice when you’re not dealing with standard sterling.
Formula: Value = Weight (g) x Purity x Spot Price (per gram)
Worked example: A 50-gram item that’s 99.9% pure (fine silver), with spot price at $1.10/gram: 50 x 0.999 x $1.10 = $54.95 in melt value.
Good fit for: Bullion, bars, and coins with a marked purity that isn’t standard sterling. Not the right tool for: Estimating a realistic sale price – this gives melt value only, not what a buyer will actually pay (see the Scrap Payout tool below for that).
2. Sterling Silver (925) Value
Sterling silver – the standard for jewelry, flatware, and tableware – is 92.5% pure silver alloyed with 7.5% other metal, almost always copper, to make it more durable than pure silver. This tool has that 92.5% purity built in, so you only need to enter weight and spot price.
Formula: Value = Weight (g) x 0.925 x Spot Price (per gram)
Worked example: A 120-gram sterling silver tea set, spot price at $1.05/gram: 120 x 0.925 x $1.05 = $116.55 in melt value.
Good fit for: Jewelry, flatware, and anything stamped “925” or “sterling.” Not a great fit for: Silver-plated items – plating is a thin coating over a base metal, not solid sterling, and holds far less silver than its size suggests. See our Silver Plate Value Calculator for that instead.
3. Scrap Silver Payout Estimate
This is the tool most people actually need when they’re planning to sell. Melt value is a ceiling, not a real offer – every buyer between you and a refinery has testing, refining, and shipping costs, plus their own margin. Based on typical industry ranges, pawn shops tend to pay the least (often 50-70% of melt), general local dealers pay somewhere in the middle (70-90%), and specialized online refiners tend to pay the most (80-95%), since they handle larger volumes more efficiently.
Formula: Melt Value = Weight x Purity x Spot Price, then Estimated Payout = Melt Value x Dealer Payout %
Worked example: A 200-gram sterling silver set (92.5% pure), spot price $1.05/gram, selling to a dealer offering 80% of melt: melt value is 200 x 0.925 x $1.05 = $194.25, so the estimated payout is $194.25 x 0.80 = $155.40.
Good fit for: Getting a realistic number before you sell, and comparing offers from different buyers. Worth knowing: Always get quotes from more than one buyer – a shop paying 55% of melt and a refiner paying 90% of melt can mean a large difference on the exact same items.
4. Silver Value by Ounces & Price
The simplest version of the calculation, for when you already know a per-ounce price (common with bullion coins and bars, which are usually quoted this way rather than by gram).
Formula: Value = Troy Ounces x Price per Troy Ounce
Worked example: 5 troy ounces at $32/oz: 5 x $32 = $160.
Good fit for: Bullion coins and bars sold by the ounce. One thing to double-check: silver is always priced per troy ounce, which is heavier than the regular ounce you’d use to weigh food (about 31.1 grams versus 28.35 grams) – using the wrong one will throw off your numbers by about 10%.
Where Does the Silver Spot Price Actually Come From?
The “spot price” you plug into any of the calculators above isn’t set by one company or website. It’s discovered continuously through real trading, mainly on two venues: the COMEX futures exchange in New York (part of CME Group, where silver contracts trade nearly around the clock), and the London Bullion Market Association’s daily benchmark auction. As buyers and sellers trade throughout the day, the most recent matched price becomes the quoted spot price you see on financial sites and dealer calculators.
One thing worth understanding: spot price is a wholesale, institutional number – it doesn’t include the cost of turning raw silver into a coin or bar, shipping, dealer margin, or insurance. That’s why a retail buyer always pays somewhat above spot (called a “premium”), and why a scrap seller receives somewhat below melt value, as covered in the Scrap Payout section above.
A Special Case: Junk Silver Coins
If what you have is pre-1965 U.S. dimes, quarters, or half dollars – often called “junk silver” – there’s a shortcut. These coins are a standardized 90% silver, and by long-standing rule of thumb, every $1 in face value contains approximately 0.715 troy ounces of pure silver. So $10 in face value (for example, 40 quarters) contains roughly 7.15 troy ounces of silver, which you can then run through the “Value by Ounces” calculator above using the current spot price. Coin dealers usually price junk silver closer to its full melt value than scrap sterling, since standardized coins need no testing to verify purity.
Understanding Silver Purity Marks
If you’re not sure what purity to enter, the stamp on the item usually tells you:
- .999 or “Fine Silver” – 99.9% pure
- 925 or “Sterling” – 92.5% pure
- 900 or “Coin Silver” – 90% pure, the standard for pre-1965 U.S. silver coins
- 800 or “European Silver” – 80% pure, common in older European silverware
If there’s no stamp at all, that’s often a sign the item is silver-plated rather than solid silver – plated pieces are rarely marked with a purity, since there’s no meaningful percentage of silver by weight to state.
How to Weigh Your Silver Before Using This Calculator
A kitchen scale works fine for this, as long as it can measure in grams and shows at least one decimal place – many jewelry and postal scales do this well. Set the scale to grams (not ounces), zero it out with nothing on it, then weigh the item on its own. For jewelry with stones, note that gemstones add weight without adding silver value, so a piece with large stones will slightly overstate its silver content if you weigh it as-is – this rarely matters much for costume pieces, but is worth factoring in for anything with sizeable gems.
If you don’t have a scale, many post offices, pharmacies, and jewelry stores will weigh small items for free or a small fee. For a large collection like a full flatware set, a reputable dealer will always weigh items in front of you as part of getting a quote – and as covered above, that transparency is a good sign you’re dealing with a legitimate buyer.
Common Mistakes When Valuing Silver
Using the wrong ounce. As covered above, silver is priced per troy ounce, not the everyday ounce used for cooking or shipping – mixing them up understates value by about 10%.
Assuming melt value is what you’ll be paid. Melt value is a ceiling. A realistic sale price is melt value multiplied by a dealer’s payout percentage, which is exactly what the Scrap Payout calculator above is for.
Treating silver plate like solid silver. A silver-plated item might weigh the same as a solid sterling piece but contain only a tiny fraction of the silver – use the Silver Plate Value Calculator for these instead, not the tools above.
Forgetting that weighted items aren’t solid. Candlesticks, trophy bases, and some figurines are often weighted with cement or another filler under a silver shell – only the shell’s silver content counts toward value, not the full weight of the piece.
Looking for Gold Instead?
If you’re comparing metals or have gold to value alongside silver, our Gold Price Per Ounce Calculator uses the same ounce-times-price approach covered above.
Frequently Asked Questions
How do I calculate how much my silver is worth?
Multiply weight by purity (as a decimal) and by the current spot price. Use the Scrap Payout tool above if you want a realistic sale estimate rather than theoretical melt value.
What’s the difference between melt value and what a dealer will actually pay?
Melt value is the silver content’s raw worth. Actual dealer payouts run anywhere from about 50% of melt at pawn shops up to 95% at specialized refiners, since every buyer has their own costs and margin built in.
Is sterling silver the same as pure silver?
No – sterling is 92.5% silver alloyed with other metal for durability. Pure or “fine” silver is 99.9%. Silver-plated items are different again: a thin silver coating over a base metal, valued completely differently from solid sterling.
What’s a troy ounce, and is it different from a regular ounce?
Yes – a troy ounce (about 31.1 grams) is heavier than the everyday ounce (about 28.35 grams). Silver spot prices are always quoted per troy ounce.
Where does the spot price come from?
It’s discovered continuously through trading on the COMEX futures exchange and the London Bullion Market Association’s daily benchmark auction – not set by any single source.
How much is my junk silver worth?
Pre-1965 U.S. dimes, quarters, and half dollars are 90% silver. As a rule of thumb, $1 in face value contains about 0.715 troy ounces of silver – multiply that by the current spot price for an estimate.
