Scrapped Cars Mass Calculator

The Scrapyard Scale

Calculate the total mass of all automobiles scrapped in North America every month.

Estimate: 300 million vehicles

Avg: 5% per year

Avg: 1,800 kg (4,000 lbs)

Mass Scrapped Monthly
2,250,000
Metric Tons
Cars: 1,250,000

What is the Scrapyard Scale?

This calculator estimates the total mass of vehicles that reach the end of their life every month in North America. It's a massive recycling operation that processes millions of tons of steel, aluminum, and other materials.

By estimating the total vehicle fleet and the average scrappage rate, we can visualize the sheer volume of material that flows through the automotive recycling ecosystem.

The Logic

The Calculation

Mass = (Fleet × Rate / 12) × AvgMass

We first find the number of cars scrapped per month, then multiply by the average mass of a vehicle.

Key Assumptions

  • Fleet: There are roughly 300 million vehicles in North America.
  • Scrappage: About 5% of the vehicle fleet is scrapped every year.
  • Mass: The average modern vehicle weighs about 1,800 kg (4,000 lbs).

Frequently Asked Questions

How much is recycled?

About 86% of a vehicle's material content is recycled. Steel and aluminum are the most valuable components.

How many cars are scrapped daily?

Based on these assumptions, over 41,000 cars are scrapped every single day in North America.

What about EVs?

EVs are generally heavier due to their batteries, which will increase the total mass scrapped as they reach the end of their life.

Why 5%?

This is a standard industry average for vehicle retirement, though it varies based on economic conditions.

This calculator uses the Fermi estimation method. Results are theoretical and intended for educational purposes.
