Methodology and FAQ

How This Scrap Metal Price Calculator Works

The calculator gives a fast estimate for U.S. scrap payouts. It is designed for one job: helping you see a realistic value range before you drive to the yard.

Formula

Every estimate starts with the same equation:Estimated payout = Weight x Spot price x Grade multiplier

Example: if copper spot is $4.12/lb, your load is 120 lb, and the grade multiplier is 0.88, then estimated payout is $435.07.

Why Grade Multipliers Matter

Scrap yards do not usually pay raw spot. They discount for prep time, contamination risk, and resale margin. Grade multipliers model those real-world deductions.

Material QualityTypical Multiplier RangeWhat Changes It
Clean, sorted grades0.80x to 0.97xLow contamination, strong local demand
Mixed grades0.55x to 0.79xSorting needed, mixed alloys, inconsistent prep
Dirty or insulated loads0.32x to 0.60xExtra processing, waste removal, moisture, debris

Price Freshness Policy

We show a last-updated timestamp with each price snapshot. If a live provider is delayed, the app can show the latest successful snapshot and mark it as stale.

This keeps the calculator usable during temporary feed outages, but stale data should always be treated as a rough planning number.

FAQ

Is this the same as a scrap yard quote?

No. This is a market-based estimate. Your final offer depends on yard policy, contamination, and local demand.

How much is scrap copper worth per pound today?

The exact number moves during market hours. Use the live copper page and multiplier table to get your current estimate.

Does this work for steel and aluminum too?

Yes. The calculator covers copper, aluminum, steel, brass, stainless, lead, zinc, nickel, silver, gold, and iron.

What should I do before visiting a yard?

Weigh each material separately, sort by grade, and remove obvious contamination. Cleaner loads usually get a better multiplier.
