Administrative Assistants: $24,985/yr in AI-Addressable Work (2026)
Most "AI will automate X% of jobs" claims are unsourced. This page does the opposite: it builds a administrative assistant ROI estimate task by task, from three sealed public datasets, and shows its work on every number so you can check it.
Headline: a administrative assistant carries about 839 AI-addressable hours a year. At a loaded rate of $29.78/hour that is $24,985 of gross value; after a stated $12,000/year tooling budget, the Year-1 net is $12,985 per full-time employee.
Those numbers are a planning estimate built from defaults, not a quote. The three inputs — task hours, wage, and AI-addressable share — come from sealed public datasets; the three assumptions — a 2,080-hour work year, a 1.3× labor-loading multiplier, and the tooling budget — are stated in the open and adjustable in the calculator at the foot of this page. Change them and every figure recomputes.
Who this is for
Operations, finance, and HR leaders — and anyone building the business case for an AI assistant aimed at secretaries and administrative assistants. If you need a number you can defend in a budget meeting, with a citation behind every cell, this is built for you.
How much of a administrative assistant's work is AI-addressable?
Across all administrative assistant work, the Anthropic Economic Index observes an AI-exposure rate of 45.3% — meaning 45.3% of this occupation's measured Claude.ai task interactions showed an automation or augmentation pattern. That is an observed-usage figure, not a ceiling on what is technically possible.
At the task level the picture is sharper. O*NET lists 31 distinct work tasks for this role. Of those, 11 have their own task-specific usage measurement in the Anthropic Economic Index; the remainder fall back to the occupation-level exposure above, and every row in the table below is labelled with which source it used (aei_task for a task's own data, aei_occ for the occupation fallback). We never silently mix the two.
For scale: BLS counts 1,737,820 people employed in this occupation nationally, at a mean wage of $47,640 a year. That wage is the spine of the dollar figures here.
The sealed task breakdown
Each row is one ONET task. Importance and Relevance are sealed ONET ratings; modeled hours allocates a 2,080-hour year across tasks in proportion to Importance×Relevance; AI-addressable share is the Anthropic Economic Index usage figure; hours saved and gross value follow from them. The table shows the 14 highest-value addressable tasks.

Reading one row: the top task above is modeled at 95 hours/year; the Economic Index puts its AI-addressable share at 51.6%, so 49 hours are addressable, worth $1,462 at the loaded rate. Nothing is rounded up: hours saved is hours × share, full stop.
The ROI math, in full
No black box. Here is every step:
Loaded hourly cost = (mean annual wage $47,640 ÷ 2,080 hours) × 1.3 loading = $29.78/hour. The 1.3× covers benefits, payroll tax, and overhead on top of base pay.
Addressable hours saved = the sum of (task hours × AI-addressable share) across the role's addressable tasks = 839 hours/year.
Gross annual value = 839 hours × $29.78 = $24,985/year.
Net Year-1 ROI = $24,985 gross − $12,000 stated tooling budget = $12,985 per FTE.
The break-even point is worth stating plainly: this role's AI-addressable work is worth $24,985 a year at the loaded rate, so any tooling spend below $24,985 per FTE is net-positive on hours alone — before any quality, speed, or capacity upside.
Methodology and honest limitations
The single most important caveat: the Anthropic Economic Index measures observed Claude.ai usage patterns, not a theoretical "this much of the job can be automated." A high share means practitioners are already routing that task to AI; a low share can mean the task is hard to automate or simply that few people have tried. Treat these as a grounded default, then replace them with your own automatable share in the calculator — that is exactly what it is for.
The hour-allocation heuristic. O*NET does not publish hours per task, so we allocate the work year in proportion to each task's Importance×Relevance. It is a transparent, defensible split, not a stopwatch study; if you know your team spends disproportionate time on one task, the calculator lets you see the table and reason about it.
Why Importance×Relevance? O*NET rates each task on how important it is to the role and how relevant it is to a typical worker (the share who actually perform it). Multiplying the two ranks tasks by real time-pull — a high-importance task nearly everyone does outranks a niche one — which is precisely the weighting you want when dividing a fixed work-year. It is the most defensible allocation available short of a per-employer time study, and any row you disagree with is editable in the calculator below.
The wage is a national mean. BLS OEWS reports a $47,640 mean across all employers nationally (median $46,290). Your local, loaded cost may differ; set your own wage to localize the dollars.
What this is. A sourced, reproducible first estimate to start a buying conversation — not a guarantee of savings. The value of the method is that every input is sealed and checkable, so a skeptic can audit it rather than argue with a vendor's slide.

FAQ
Is "45.3% AI exposure" the share of the job AI will replace?
No. It is the share of measured Claude.ai task interactions for this occupation that showed an automation or augmentation pattern — an observed-usage signal, not a replacement forecast.
Where does the $47,640 wage come from?
BLS Occupational Employment and Wage Statistics, May 2024 — the national mean annual wage for this occupation, used verbatim from the sealed snapshot.
How do you get 839 hours saved?
For each addressable task we multiply its modeled annual hours by its AI-addressable share, then sum. Modeled hours allocate a 2,080-hour year by each task's O*NET Importance×Relevance.
Can I change the assumptions?
Yes — the calculator below this article lets you set the wage, the work-year hours, the labor-loading multiplier, the tooling budget, and each task's automatable share. The net ROI updates live.
Why these three data sources?
O*NET gives the tasks, BLS gives the labor cost, and the Anthropic Economic Index grounds "how much is AI-addressable" in real usage rather than a guess. Each is public and pinned to a sealed snapshot.

The math above is the business case; the next step is watching it run. USTA builds the agentic workflows that actually do this administrative assistant work — drafting, routing, reconciling, and updating the systems of record — so the addressable hours above convert into capacity you keep instead of headcount you chase.
