AI Employee vs Hiring Calculator

The calculator compares the total cost of hiring a human employee versus renting an AI monthly versus owning an Apex AI employee outright. For a human hire, the annual cost is: (Annual Salary + Employer Taxes + Benefits + Training + Recruiting Costs + Overhead) * (1 + Turnover Rate). Employer taxes are typically 7.65% of salary for Social Security and Medicare, plus state unemployment taxes (e.g., 2.7% on first $7,000). Benefits average 30% of salary. Training costs include onboarding time and materials, estimated at $4,000. Recruiting costs average $4,000 per hire. Overhead includes office space, equipment, and software, estimated at $12,000 per year. Turnover rate is the probability of replacement per year (e.g., 15% = 0.15). For AI rental, the annual cost is: Monthly Rental Fee * 12, with no additional costs. For owning an Apex AI employee outright, the cost is the one-time purchase price plus any annual maintenance fee (if applicable). The net savings over 1 year is: Human Cost - (AI Rental Cost or Ownership Cost). Over 3 years, it's the sum of annual costs for human (including turnover each year) minus the sum of annual costs for AI rental (same fee each year) or the ownership cost (one-time plus any maintenance). The formula avoids benchmarks by using user-inputted variables.

A good number for savings is any positive value, indicating the AI option costs less than a human hire. The greater the human cost (high salary, benefits, turnover), the larger the savings. For AI rental, savings are typically smaller than ownership over 3 years because rental fees accumulate, but rental offers flexibility. Ownership savings become substantial after the first year since no recurring fees (except possible maintenance). There is no universal 'good' range because it depends on your specific inputs; instead, focus on the payback period: how many months of human salary it takes to offset the AI purchase. For example, if human monthly cost is $8,000 and AI ownership is $60,000, payback is 7.5 months. Any payback under 12 months is generally attractive. Be cautious: this calculation assumes AI performance equals human output, which may not be true for all tasks. Also, turnover rates vary by industry—tech often has 13%, retail 60%—so adjust based on your experience.

A common mistake is forgetting to include all human costs like training, recruiting, and overhead, leading to an underestimate of human expenses. Another is ignoring turnover: if you assume no turnover, you miss the cost of rehiring and retraining, which can be 50% of salary. Edge cases include part-time employees (adjust benefits and overhead proportionally) or contractors (no benefits or taxes, but higher hourly rate). Also, people often assume AI rental costs are fixed, but some services raise prices; use current rates. For ownership, forgetting annual maintenance fees (e.g., 10% of purchase price) can skew savings. Finally, not accounting for the time value of money—though for short 1-3 year comparisons, it's minor.

Turnover Rate

The percentage of employees who leave in a year, requiring replacement and incurring additional recruiting and training costs.

Employer Taxes

Payroll taxes paid by the employer, including Social Security, Medicare, and federal and state unemployment taxes.

Overhead

Indirect costs per employee such as office space, equipment, software licenses, and utilities.

AI Rental

Monthly subscription fee for accessing an AI employee service, with no long-term commitment.

AI Ownership

One-time purchase of an Apex AI employee license, potentially with optional annual maintenance.
