AI vs Human Cost — Cluster C
AI vs Administrative Assistant —
Cost, Productivity & When to Go Hybrid
A Administrative Assistant costs $63K/year fully loaded (BLS 2024). An AI stack costs an estimated $4K–$10K/year. Autonomy level: 7/10. Here is the full breakdown — with data, not guesses.
Cost Comparison: Human vs. AI vs. Hybrid
All human costs use BLS OEWS 2024 median wages with a 1.43× fully-loaded multiplier (BLS ECEC Q3 2024: wages are 70% of total compensation). AI costs are market estimates, clearly labeled. Verify against your actual vendor contracts before making decisions.
| Configuration | Annual Cost | vs. Human | Best For |
|---|---|---|---|

Fully Human
BLS median $44K base · 1.43× loaded
|
$63K | — | Judgment-heavy work, complex relationships, regulatory sign-off |

AI Stack Only
Microsoft 365 Copilot, Otter.ai, Calendly, Notion AI · Estimate

$4K–$10K −90% est. | ~90% lower | Structured, high-volume, rules-based tasks with low error stakes |

Hybrid Stack ★ Recommended
Human overseer + AI for volume · Estimate
|
$25K–$38K −50% est. | ~50% lower | Best of both — human judgment where it counts, AI scale where it doesn't |
Human cost: BLS OEWS May 2024, SOC 43-6014. BLS ECEC Q3 2024 fully-loaded multiplier 1.43×. AI costs: estimates based on Q1 2026 market pricing for Microsoft 365 Copilot, Otter.ai, Calendly, Notion AI. AI productivity suite + scheduling automation + meeting summarization + document drafting. 0.1 FTE oversight. Estimate.
AI Autonomy Level: 7/10
AI handles 65–75% of administrative tasks — calendar management, email drafting, meeting summaries, document formatting, and data entry. Physical presence tasks, executive-level discretion, and sensitive external communications require human judgment.
The autonomy level measures how much of the role AI can perform independently and reliably today — not theoretically. A 7/10 means roughly 65–80% of tasks are automatable with current production AI. A 10/10 means full automation is viable with minimal human oversight.
When to Keep Human vs. When to Automate
- High-discretion executive support requiring confidentiality and judgment
- In-person meeting facilitation, travel logistics, and physical office tasks
- Stakeholder relationship management and sensitive external communications
- Ad hoc requests requiring context, initiative, and cross-functional coordination
- Managing vendor relationships and negotiating office services
- Calendar scheduling, rescheduling, and meeting room coordination
- Meeting transcription, summarization, and action item extraction
- Email drafting, inbox triage, and follow-up reminders
- Document formatting, template population, and filing
- Expense report data entry and receipt organization
Hybrid Blueprint
0.5 FTE human admin handles executive-level support and physical office coordination. AI manages the volume layer: scheduling, email drafts, meeting summaries, document prep, and data entry. Companies often eliminate 1 of 2 admin headcount while improving turnaround times.
Hybrid is not a compromise — it is the highest-performing configuration for most Administrative Assistant functions. Human judgment handles exceptions and relationships; AI handles volume and consistency. The result: lower cost than a full human team, better coverage than AI alone.
