Silver Profit Formula
The silver profit calculation compares the selling price per pound with the purchase price per pound, then multiplies the difference by the silver weight in pounds.
SP = (S - P) * W
- SP = silver profit, in dollars
- S = selling price of silver, in dollars per pound
- P = purchase price of silver, in dollars per pound
- W = weight of silver, in pounds
If you leave a different field blank, the calculator rearranges the same formula:
S = (SP / W) + P
P = S - (SP / W)
W = SP / (S - P)
- Selling price function: use this when you know your profit target, purchase price, and silver weight.
- Purchase price function: use this when you know the selling price, profit, and weight, and need to find the break-even buying price for that profit.
- Weight function: use this when you know the price spread and target profit, and need to find how much silver is required.
- Profit function: use this when you know the selling price, purchase price, and weight.
Because the price fields are in dollars per pound, the calculator converts the entered weight to pounds before applying the formula.
Silver Weight Conversion Factors
Use these conversions to understand how the calculator standardizes weight before calculating profit.
| Entered Unit | Pounds Used in Formula | Example |
|---|---|---|
| Pounds, lb | 1 lb = 1 lb | 10 lb = 10 lb |
| Kilograms, kg | 1 kg = 2.20462 lb | 10 kg = 22.0462 lb |
| Grams, g | 1 g = 0.00220462 lb | 500 g = 1.10231 lb |
| Ounces, oz | 1 oz = 0.0625 lb | 16 oz = 1 lb |
Silver Profit Result Guide
| Result | Meaning |
|---|---|
| Positive profit | The selling price is higher than the purchase price. |
| Zero profit | The selling price and purchase price are the same. |
| Negative profit | The selling price is lower than the purchase price, so the trade is a loss before any fees. |
Example Problems
Example 1: Calculate silver profit
You buy silver for $280 per pound and sell it for $320 per pound. The weight is 12 pounds.
SP = (320 - 280) * 12
SP = 40 * 12 = 480
The silver profit is $480.00.
Example 2: Calculate required selling price
You paid $250 per pound for 8 pounds of silver and want a profit of $600.
S = (600 / 8) + 250
S = 75 + 250 = 325
The required selling price is $325.00 per pound.
FAQ
Does this calculate silver profit by troy ounce?
No. The selling price and purchase price fields are in dollars per pound. If your silver price is quoted by troy ounce, convert it to dollars per pound before entering it, or use a consistent unit outside the calculator.
Why does the calculator convert the weight to pounds?
The price inputs are labeled as dollars per pound, so the weight must be in pounds for the formula to work. If you enter kilograms, grams, or ounces, the calculator converts that weight to pounds first.
Does the result include dealer fees, shipping, taxes, or refining costs?
No. The result is based only on selling price, purchase price, and weight. Subtract any extra costs separately if you want net profit.
