AI vs Human Cost Calculator | The People Stack

Q: How does this workforce stack cost calculator work?

Enter your role, location, and headcount. The calculator applies BLS OEWS Q4 2024 salary data, benefits loading rates (18–28% by company size), payroll taxes, overhead, recruiting, and training to compute true fully-loaded human cost. AI stack costs use real platform pricing plus maintenance, setup amortized over 3 years, and oversight FTE fractions — then models your optimal hybrid configuration.

Q: What is included in the fully-loaded human cost?

Fully-loaded human cost includes: base salary, employer payroll taxes (7.65%), benefits (health, dental, vision, retirement, PTO), overhead (office space, equipment, software, HR allocation), management tax (15%), annual recruiting cost, and onboarding/training expenses. All figures are sourced from BLS ECEC and SHRM benchmarks.

Q: How accurate are the AI stack cost estimates?

AI stack costs are based on current Q1 2026 market pricing for leading platforms in each category — e.g., Intercom/Zendesk AI for support, GitHub Copilot/Cursor for engineering, Salesforce Einstein for sales. Costs include: platform/API fees, maintenance (15% annually), one-time setup amortized over 36 months, and partial oversight FTE.

Q: What is the hybrid stack model?

The hybrid stack reflects the optimal real-world configuration: approximately 35% of the team remains human (for judgment, relationships, and complex edge cases) while 65% of work capacity is handled by AI. Hybrid stacks consistently outperform all-human or all-AI configurations for most business functions.

Q: Does AI cost less for larger teams?

Yes — AI exhibits sublinear scaling. Each additional seat costs significantly less than the first because platform licensing often caps or uses tiered pricing. The calculator applies a 30% sublinear cost factor per additional AI “seat”, reflecting real enterprise SaaS pricing patterns.

AI vs Human Cost Calculator — Compare True Workforce Costs

Every workforce decision starts with a cost question: should we hire a human, deploy AI, or build a hybrid stack? The answer is almost never obvious — and the stakes are high. According to the Bureau of Labor Statistics (BLS OEWS May 2024), the median US annual wage is $48,060, but fully-loaded human cost runs 1.25–1.43× that figure once you account for employer payroll taxes (7.65%), health and retirement benefits (SHRM estimates 30–35% of base salary), recruiting fees (20–25% of first-year salary per SHRM), and management overhead. A $70K salary role typically costs $97,000–$100,000 per year, fully loaded.

AI deployment costs are structured differently: platform licensing (often tiered by seat or usage), one-time setup and integration, ongoing maintenance, and a partial human oversight FTE. The true cost comparison requires modeling all three configurations — human FTE, full AI replacement, and the hybrid 65/35 split — side by side with the same time horizon. This calculator does exactly that, using BLS salary data and Q1 2026 AI platform pricing so you can make decisions based on real numbers, not rough estimates.

Select a role below to see the fully-loaded human cost, AI stack cost, hybrid configuration, and break-even timeline for your company size and location. All cost formulas and data sources are shown inline — every number is verifiable.

How This Calculator Works

1
Choose a role or department. Select from 31 pre-loaded roles (spanning Operations, Marketing, Sales, Engineering, HR, and Finance) or enter a custom role name. Each pre-loaded role has BLS OEWS 2024 median salary data for your selected location tier — US High Cost (SF/NYC/Seattle), US Mid Cost (Austin/Chicago/Denver), US Lower Cost (Southeast/Midwest), Canada, or Western Europe.
2
Set headcount and company size. The calculator adjusts the fully-loaded cost multiplier based on company size: smaller companies pay higher benefits overhead per employee; larger companies have more negotiating leverage on healthcare but higher HR allocation costs. Adjusting headcount scales the AI sublinear cost discount (typically 30% per additional unit, reflecting tiered SaaS pricing).
3
Review the three-scenario cost table. The calculator computes: (1) Full Human FTE cost using BLS ECEC benefits loading (33% of base per Q3 2024), employer payroll taxes (7.65%), recruiting cost (SHRM: 21% of first-year salary), and overhead; (2) Full AI Replacement using Q1 2026 platform pricing plus 15% annual maintenance and 0.25 FTE human oversight; (3) Hybrid Stack (65% AI / 35% human) showing blended cost and output multiplier.
4
Check the break-even timeline and autonomy score. The calculator shows how many months until AI or hybrid costs are recouped against the current fully-loaded human cost — including transition costs, ramp time, and a productivity dip buffer. The L0–L4 AI autonomy score tells you how far the technology has come for this specific role type based on McKinsey 2025 automation potential data.
5
Use the results to make your case. Every number in the output is backed by a data source citation (BLS OEWS, BLS ECEC, SHRM, McKinsey). Download or screenshot the comparison table to use in your workforce planning discussion, CFO conversation, or board presentation. The output is designed to be a defensible decision artifact, not just a number on a screen.

Common questions about AI vs. human costs

What is the fully loaded cost of a human employee? +

A fully loaded employee costs 1.25–1.40x their base salary. For a $70,000 salary, the true annual cost is typically $87,500–$98,000 when you include employer payroll taxes (7.65%), health insurance ($8,000–$15,000/year), 401(k) matching (3–6%), paid time off (15–20 days), recruiting fees ($5,000–$25,000), onboarding training, and management overhead (20–30% of salary). Source: BLS Employer Costs for Employee Compensation (ECEC), Q4 2024.

How much does it cost to deploy an AI alternative? +

AI deployment costs vary by role but typically run $15,000–$85,000 annually, versus $85,000–$200,000+ for a fully loaded human FTE. Costs include AI platform/API usage ($5,000–$30,000/year), integration and maintenance ($10,000–$30,000/year), human oversight (0.25–0.5 FTE), and initial setup ($5,000–$25,000 amortized over 3 years). Best-suited roles: data entry, customer support tier 1, content generation, research, scheduling. Sources: Anthropic, OpenAI published pricing; Deloitte AI Deployment Cost Benchmark 2025.

What is the typical break-even timeline for AI vs. hiring? +

Most companies reach break-even between 4–18 months. High-volume, structured roles (support, data entry, content) break even fastest (4–8 months). Knowledge-intensive roles requiring judgment (product, strategy) take 12–18+ months. Break-even accelerates with team size — replacing 5 support reps breaks even ~3x faster than replacing 1. The calculator accounts for implementation costs, ramp time, and productivity delta.

Which roles are best suited for AI vs. human? +

High AI-suitability (70–90% automatable): data entry clerks, customer support tier 1, high-volume content writers, structured research analysts, schedulers.

Hybrid-optimal (30–60% automatable): marketing coordinators, sales development reps, finance analysts, HR generalists, QA engineers.

Low AI-suitability (<20%): strategic leadership, complex B2B enterprise sales, therapists, skilled trades, executive decision-makers.

Does this calculator use real salary data? +

Yes. Base salaries use U.S. Bureau of Labor Statistics Occupational Employment and Wage Statistics (OEWS) program data, updated through Q4 2024. The calculator labels BLS-sourced figures clearly. AI cost estimates are based on published pricing from Anthropic and OpenAI plus deployment cost studies from Deloitte and McKinsey. All formulas are shown in the detailed breakdown.
