The basic formula
Estimate each material separately, then add the results: material weight × quoted price per unit = estimated material value. If your quote is per pound, use pounds. If it is per kilogram, use kilograms.
A mixed load is rarely paid as though every pound were the highest-value metal. Separating grades gives you a more useful estimate and a cleaner conversation at the scale.
Estimate your load in five steps
Use a repeatable process so the estimate can be compared with the final scale ticket.
- Separate the load by material and grade—for example, insulated copper wire, bare copper, brass, aluminum, stainless steel, and prepared or unprepared steel.
- Remove obvious non-metal attachments only when it is safe, lawful, and worth the time. Never burn insulation or coatings.
- Weigh each group. A platform scale is useful for containers; record and subtract the empty container weight.
- Call the yard for its current buying quote and ask how it grades your exact material. Prices and definitions vary by yard, location, preparation, and market conditions.
- Multiply each weight by its matching quote, add the material estimates, and compare the result with fuel, time, tolls, and other trip costs.
Example without a market-price claim
Suppose you have 18 pounds of one copper grade and your chosen yard quotes that grade at $X per pound. That portion is 18 × X. Repeat the calculation for every other grade, then add the results.
This method deliberately uses the quote you received instead of a generic internet price. The yard's scale weight and grading decision determine the actual payout.
What can change the final payout
An estimate is a planning tool, not a guaranteed offer. Common differences come from material grade, contamination, moisture, attachments, prepared-size rules, scale weight, minimum quantities, and price movement between the quote and the sale.
- Ask how long a quote is valid and whether it requires a minimum weight.
- Photograph or label sorted groups so you can review a grade change.
- Keep the scale ticket and record the final weight, grade, and payout for future estimates.
Use ScrapValue for the repeatable part
ScrapValue lets you enter material and weight information, estimate a mixed load, and save the run. The free version is enough to try a three-line load. Using your own local quote in ScrapValue Pro makes the calculation specific to the yard you plan to visit.
