Loaded FTE cost

The total annual cost of a full-time-equivalent employee to the enterprise, summed across base salary, employer-side payroll taxes, benefits (health, retirement match, disability, life), allocated facilities cost, allocated IT and software per-seat licensing, training and development budget, recruiting amortisation, and management overhead. The benefits-and-overhead load typically runs 35 to 55% on top of base salary; for typical knowledge-work roles in 2026 developed-economy markets, the all-in band sits at $90,000 to $180,000.

Loaded FTE cost is the load-bearing variable in any agent-vs-human substitution analysis. Most enterprise AI ROI calculations make one of two errors: comparing the agent against base salary only (ignoring the 35-55% load) or comparing against fully-loaded cost without adjusting for the agent's own loaded operational cost (model inference, orchestration, integration, observability, oversight). The comparison that survives review is loaded FTE versus complete agent cost stack, modelled at production volume rather than pilot volume.
