Construction AI ROI Calculator

Estimate the financial return on investment from deploying AI tools on construction projects, accounting for rework reduction, schedule compression, labor productivity gains, and implementation costs.

Total Project Value ($)

Total contract or project budget in USD

Current Rework Rate (% of project cost)

Industry average is 5–15% of total project cost

AI Rework Reduction (%)

Typical AI-driven reduction: 25–50% of rework costs

Annual Labor Cost ($)

Total annual wages and benefits for project workforce

AI Labor Productivity Gain (%)

Typical AI productivity improvement: 5–20% (McKinsey, 2023)

Project Duration (months)

Total planned project duration in months

AI Schedule Compression (%)

Reduction in project duration from AI scheduling tools (typical: 5–15%)

Monthly Overhead / Delay Cost ($/month)

Fixed overhead, financing, and penalty costs per month of project duration

Annual Safety Incidents (count)

Recordable incidents per year on this project

Average Cost per Incident ($)

Direct + indirect costs; OSHA estimates ~$40,000 per recordable incident

AI Safety Incident Reduction (%)

AI vision/monitoring tools reduce incidents by 15–35% (Dodge Data, 2022)

AI Implementation Cost ($)

Total cost: software licenses, integration, training, and support

// --- Core Calculations ---

// 1. Rework Savings // Rework Cost = Project Value × (Rework Rate / 100) // Rework Savings = Rework Cost × (Rework Reduction / 100) const reworkCost = projectValue * (reworkRate / 100); const reworkSavings = reworkCost * (reworkReduction / 100);

// 2. Labor Productivity Savings // Labor Savings = Annual Labor Cost × (Productivity Gain / 100) // Annualized over project duration (months / 12) const projectYears = scheduleMonths / 12; const laborSavings = laborCost * (productivityGain / 100) * projectYears;

// 3. Schedule Compression Savings // Months Saved = Schedule Months × (Schedule Compression / 100) // Schedule Savings = Months Saved × Monthly Overhead Cost const monthsSaved = scheduleMonths * (scheduleCompression / 100); const scheduleSavings = monthsSaved * overheadMonthly;

// 4. Safety Savings // Annual Safety Cost = Incidents × Cost per Incident // Safety Savings = Annual Safety Cost × (Safety Reduction / 100) × Project Years const annualSafetyCost = safetyIncidents * costPerIncident; const safetySavings = annualSafetyCost * (safetyReduction / 100) * projectYears;

// 5. Total Benefit & ROI // Total Benefit = Rework Savings + Labor Savings + Schedule Savings + Safety Savings // Net Benefit = Total Benefit - AI Implementation Cost // ROI (%) = (Net Benefit / AI Implementation Cost) × 100 // Payback (months) = AI Cost / (Total Benefit / Schedule Months) const totalBenefit = reworkSavings + laborSavings + scheduleSavings + safetySavings; const netBenefit = totalBenefit - aiCost; const roi = aiCost > 0 ?

#### Formulas Used

1. Rework Savings Rework Cost = Project Value × Rework Rate Rework Savings = Rework Cost × AI Rework Reduction %

2. Labor Productivity Savings Labor Savings = Annual Labor Cost × Productivity Gain % × (Project Duration in Years)

3. Schedule Compression Savings Months Saved = Project Duration × Schedule Compression % Schedule Savings = Months Saved × Monthly Overhead Cost

4. Safety Savings Annual Safety Cost = Incidents × Cost per Incident Safety Savings = Annual Safety Cost × Safety Reduction % × Project Years

5. ROI & Payback Total Benefit = Rework + Labor + Schedule + Safety Savings Net Benefit = Total Benefit − AI Implementation Cost ROI (%) = (Net Benefit / AI Cost) × 100 Payback (months) = AI Cost / (Total Benefit / Project Duration in Months)
