How to Calculate Scrap Price per kg (Step-by-Step 2026 Guide)
Selling scrap materials is only profitable when you know their exact value. Many businesses struggle to calculate scrap price per kg accurately, leading to underpriced sales or missed profit opportunities. Scrap value depends on type, grade, purity, and market fluctuations, making real-time calculations essential. In this guide, you’ll learn how to calculate scrap price per kg for metals, e-waste, plastics, and machinery. We’ll cover step-by-step formulas, pricing examples in USD and AUD, tips to maximize returns, and how to leverage digital marketplaces for accurate valuations. By the end, you’ll be able to confidently price your scrap, whether selling locally or on global platforms, and ensure every kilogram generates maximum revenue.
Step 1: Identify the Scrap Type and Grade
Different scrap types command different prices. Common categories include:
| Scrap Type | Examples |
|---|---|
| Ferrous Metals | Steel, iron |
| Non-Ferrous Metals | Aluminum, copper, brass |
| E-Waste | Laptops, smartphones, circuit boards |
| Plastic Scrap | Industrial plastics |
| Machinery Scrap | Engine blocks, old equipment |
Tip: Refined, clean, and sorted scrap always yields a higher price per kg.
Step 2: Find the Current Market Rate
Scrap prices fluctuate daily. Check:
- Global metal exchanges
- Local scrap yards
- Digital marketplaces like ScrapTrade, ScrapTrade Australia, ScrapTradeNow
Example:
- Copper scrap: USD 10/kg, AUD 15/kg
- Aluminum scrap: USD 3/kg, AUD 4.5/kg
Step 3: Adjust for Purity and Condition
- Purity: 100% pure metals fetch full market price; mixed or contaminated scrap is discounted
- Processing: Clean, shredded, or refined scrap commands 10–50% higher rates than raw scrap
Example:
- Aluminum market price: USD 3/kg
- Purity: 95% → 0.95
- Refined scrap bonus: 10% → 1.1
- Calculated price per kg = 3 × 0.95 × 1.1 ≈ USD 3.14/kg
Step 4: Include Local Costs and Fees
Consider:
- Transportation costs
- Marketplace fees or commissions
- Local taxes or levies
Example:
- Calculated price: USD 3.14/kg
- Transport & fees: USD 0.2/kg
- Net scrap price = 3.14 – 0.2 ≈ USD 2.94/kg
This ensures accurate profit calculations before selling.
Step 5: Multiply by Total Weight
Finally, calculate total scrap value:
Total Value = Net Price per kg × Total Weight (kg)
Example:
- Weight: 200 kg of aluminum
- Net price: USD 2.94/kg
- Total Value = 200 × 2.94 = USD 588
You now know how much your scrap is truly worth.
Step 6: Using Digital Scrap Value Calculators
For faster calculations:
- Input scrap type, weight, and purity online
- Automatically get estimated price in USD/AUD
- Connect directly to marketplaces for verified buyers
