About This Calculator
The Trump's Wall Calculator estimates the total construction cost of a US-Mexico border wall based on the design proposed during Donald Trump's presidency. Built on research by Omni Calculator founder Mateusz Mucha and civil engineer Tadeusz Zwoliński from the Warsaw University of Technology, this calculator simulates the cost of a precast reinforced concrete barrier wall.
The wall is modeled as T-shaped precast concrete panels — similar to those used at US military bases like Bagram — with a portion buried underground to prevent tunneling. Each panel is 40 feet wide, reinforced with steel rebar taking 1.8% of the volume, at a bulk cost of $350 per cubic yard of reinforced concrete. Panels are produced at plants near the border (average 150 miles away) and transported at $4 per mile.
Assembly requires excavators, cranes, bulldozers, and workers at each panel site. Ongoing costs include border patrol guards at $149,369 per officer per year (based on Chicago police cost data including salary, benefits, insurance, and equipment), plus maintenance at 15% of construction costs amortized over the project's 25-year lifetime.
The calculator also provides an opportunity cost comparison showing what else the wall budget could fund — from meals for the homeless and schools in developing countries to healthcare and education programs — based on published cost data from reputable sources.
Regional Notes
This calculator is specific to the United States. All costs are in US dollars (USD). Wall dimensions use imperial units (miles, feet) as standard in US construction. Guard cost estimates are based on US law enforcement salary data. The alternative spending comparisons use US and international development cost benchmarks.
Frequently Asked Questions
How does the Trump's Wall Calculator work?
The calculator estimates border wall construction costs by computing concrete volume from the wall's length, height, and thickness. It then calculates manufacturing, transportation, assembly, guard staffing, and maintenance costs over the project lifetime, providing a total cost estimate with detailed breakdowns.
What assumptions does the Trump Wall cost estimate make?
The calculator assumes a precast reinforced concrete panel design at $350 per cubic yard, an average transport distance of 150 miles at $4 per mile, 40-foot panel sections, a guard cost of $149,369 per officer per year, and maintenance at 15% of construction costs amortized over 25 years.
How long would the US-Mexico border wall be?
The US-Mexico border is approximately 1,954 miles long. Not all of it would need a wall due to natural barriers like rivers and mountains, but the calculator defaults to the full border length for a maximum cost estimate.
Is the Trump's Wall Calculator free to use?
Yes, it is completely free to use with no registration required. All inputs are saved in the URL for easy sharing.
What could the wall money be used for instead?
The calculator shows alternative uses including meals for homeless people, building schools in Angola, and sending children to school in Africa, based on published cost data from reputable sources.
Can I adjust the concrete cost or transport rates?
Yes, all input fields including concrete cost per cubic yard, transport distance, transport rate, assembly cost, guard count, and project lifetime are fully customizable to explore different scenarios.
How is maintenance cost calculated?
Maintenance is estimated at 15% of total construction costs per year, amortized over the 25-year project lifetime. This follows the industry standard for large infrastructure projects where maintenance typically represents 80-90% of lifetime costs.
What is the guard cost based on?
The annual guard cost of $149,369 per officer is based on Chicago Police Department data, including salary, pension contributions, healthcare, liability insurance, overtime, Medicare, uniform allowance, and workers compensation.
