Calculate Cost Per Pound
Understanding Cost Per Pound
What is Cost Per Pound?
Cost per pound is a unit rate that tells you how much you are paying for one single pound of a material. It's a fundamental metric for comparing prices, especially when dealing with commodities like metals sold by weight.
The Formula
The calculation is straightforward:
Cost Per Pound = Total Cost / Total Weight (in Pounds)
For example, if you buy 100 pounds of copper for $500, the cost per pound is $500 / 100 pounds = $5 per pound.
Cost Per Pound Examples
Click on an example to see the inputs and result:
Example 1: Small Copper Purchase
Scenario: Buying a small batch of scrap copper wire.
1. Inputs: Total Cost = $75, Total Weight = 25 pounds.

Conclusion: The copper cost $3.00 per pound in this transaction.
Example 2: Larger Commercial Lot
Scenario: Purchasing a larger volume of copper.
1. Inputs: Total Cost = $3,250, Total Weight = 500 pounds.
2. Calculation: Cost Per Pound = $3250 / 500 lbs
3. Result: $6.50 per pound.
Conclusion: The cost per pound for this bulk purchase is $6.50.
Example 3: Retail Copper Tubing
Scenario: Buying copper tubing from a hardware store.
1. Inputs: Total Cost = $42.50, Total Weight = 5 pounds.
2. Calculation: Cost Per Pound = $42.50 / 5 lbs
3. Result: $8.50 per pound.
Conclusion: Copper tubing in this case is relatively expensive at $8.50 per pound.
Example 4: Scrap Copper Sale
Scenario: Selling scrap copper to a recycling yard.
1. Inputs: Total Revenue = $180, Total Weight = 72 pounds.
2. Calculation: Price Received Per Pound = $180 / 72 lbs
3. Result: $2.50 per pound.
Conclusion: You received $2.50 per pound for your scrap copper.
Example 5: Calculating for 1 Pound
Scenario: You see a price for a single pound.
1. Inputs: Total Cost = $4.99, Total Weight = 1 pound.
2. Calculation: Cost Per Pound = $4.99 / 1 lbs
3. Result: $4.99 per pound.
Conclusion: As expected, the cost for 1 pound is the cost per pound.
Example 6: Very Heavy Lot
Scenario: A large industrial purchase.
1. Inputs: Total Cost = $28,000, Total Weight = 8,000 pounds.
2. Calculation: Cost Per Pound = $28000 / 8000 lbs
3. Result: $3.50 per pound.
Conclusion: Bulk purchases often have a lower per-pound cost ($3.50 in this case).
Example 7: Rounding Issue Check
Scenario: Dealing with non-round numbers.
1. Inputs: Total Cost = $98.75, Total Weight = 39.5 pounds.
2. Calculation: Cost Per Pound = $98.75 / 39.5 lbs
3. Result: $2.50 per pound.
Conclusion: The calculator handles decimal inputs correctly.
Example 8: Comparing Offer A
Scenario: Evaluating an offer for scrap.
1. Inputs: Total Revenue = $520, Total Weight = 200 pounds.
2. Calculation: Price Received Per Pound = $520 / 200 lbs
3. Result: $2.60 per pound.
Conclusion: Offer A pays $2.60 per pound.
Example 9: Comparing Offer B
Scenario: Evaluating a different offer for the same scrap.
1. Inputs: Total Revenue = $600, Total Weight = 230 pounds.
2. Calculation: Price Received Per Pound = $600 / 230 lbs
3. Result: $2.61 per pound (approx).
Conclusion: Offer B pays slightly more per pound ($2.61 vs $2.60).
Example 10: Estimating Unit Cost
Scenario: You bought 15 pounds for $60, but the tag was per pound.
1. Inputs: Total Cost = $60, Total Weight = 15 pounds.
2. Calculation: Unit Price = $60 / 15 lbs
3. Result: $4.00 per pound.
Conclusion: The implicit price per pound was $4.00.
Frequently Asked Questions about Copper Pricing
1. Why calculate the cost per pound?
Calculating cost per pound helps you compare prices from different suppliers or for different forms of copper (like wire vs. tubing vs. sheet) on a standardized basis, ensuring you get the best value.
2. What affects the price of copper?
Many factors influence copper prices, including global supply and demand, economic conditions, mining costs, currency exchange rates, and the grade/purity of the copper.
3. Is "scrap copper" price the same as "new copper" price?
No. Scrap copper is typically sold at a lower price per pound than new, refined copper because it requires processing and melting down. The price also varies significantly based on the type and cleanliness of the scrap (e.g., bare bright wire vs. insulated wire or plumbing). This calculator works for either scenario, you just input the cost and weight for that specific transaction.
4. What units should I use for weight?
This calculator specifically uses **pounds**. If you have weight in kilograms or other units, you'll need to convert it to pounds before using the calculator (1 kg ≈ 2.20462 lbs).
5. What units should I use for cost?
The cost input should be in the currency you are using for the total purchase price. The output will be in that same currency per pound (e.g., dollars per pound, euros per pound).
6. Can I use this for other materials sold by weight?
Yes, absolutely. While labeled for copper, the basic calculation (Total Cost / Total Weight) applies to finding the cost per pound for any material sold by weight, such as aluminum, steel, lead, or even produce like potatoes.
7. What are common forms of copper sold by weight?
Common forms include scrap wire (various grades), pipe/tubing, sheet, fittings, and ingots.
8. Why is copper weighed instead of measured by length?
For many commercial transactions and scrap dealing, weight is a more reliable and standardized measure of the total material quantity than length, especially for mixed or irregular pieces.
9. How do recycling yards determine scrap copper price?
Recycling yards base their buying price on the current market price for copper, the type and grade of the scrap, and their own processing costs. They typically weigh the material to determine the total amount.
10. Can I use this to figure out how much I'll get for selling copper?
Yes. Just input the total amount the buyer offers you as the "Total Cost" and the weight you are selling as the "Total Weight". The result will be the price you are receiving per pound.
