Executive Assistant Cost Calculator: Know Your Break-Even Point
May 18, 2026
You pay $3,500/month for a human executive assistant. Or you're considering it. Or you've never quantified the decision. Here's the question no founder asks: At what hourly value does your time exceed their salary? If your time is worth $50/hour, a $3,500/month EA is a terrible investment. If your time is worth $2,000/hour, the same EA pays for itself in less than 2 hours of work. Most founders make this decision on gut feeling ('I need help') instead of math. Here's how to calculate your break-even point—and why AI is rewriting the economics.
Step 1: Calculate Your Real Hourly Value
Most founders don't know their hourly value. They know their revenue, but they don't know the value of their time. Here's how: Start with annual revenue. At $1M revenue, assume the founder (you) generated 70% of that (the other 30% is team/operations). So you're responsible for $700k of revenue. You work roughly 2,000 hours per year (50 weeks × 40 hours—though founders work more, we'll be conservative). Your hourly value = $700,000 ÷ 2,000 = $350/hour. At $5M revenue, you're responsible for $3.5M. $3.5M ÷ 2,000 hours = $1,750/hour. At $10M revenue, $7M ÷ 2,000 = $3,500/hour. Note: this is your *generated* value, not your *cost*. You're not charging this rate. But it's what an hour of your time is worth to the business.
Step 2: Calculate the Cost of a Human EA
A full-time EA in a US market costs: Salary: $50,000–$80,000/year. Taxes & benefits: +25–30% (~$15k–$25k). Employer 401k match: +3–5% (~$2k–$4k). Total all-in cost: $70,000–$110,000 per year. Plus: 4-6 week hiring process. 8-12 week onboarding and ramp period. You're not getting full productivity for the first 3 months. Turnover: The average EA tenure is 18–24 months. So every 2 years, you're rehiring and onboarding again. Real annual cost when you factor in hiring + ramp + turnover: $85,000–$130,000 per year (or $7,000–$11,000/month). Plus your time: 5–10 hours per month managing the EA. That's another 60–120 hours/year your time to manage someone else's time.
Step 3: Map the Work (What They Actually Do)
Your EA doesn't work all 2,000 hours on things that matter. They spend time: Inbox triage: 10 hours/week (500 hours/year). Calendar management: 5 hours/week (250 hours/year). Email drafting: 5 hours/week (250 hours/year). Scheduling: 3 hours/week (150 hours/year). Follow-up tracking: 2 hours/week (100 hours/year). Meetings/admin/learning your business: 5 hours/week (250 hours/year). Actual total useful output: ~1,500 hours/year of EA work. But here's the critical part: not all of those hours are high-value. Inbox triage and calendar management are largely pattern-based. Email drafting is where they start adding real value. Follow-up tracking is moderate value. If you're paying $100/hour all-in for an EA, and they're spending 500 hours/year on low-value pattern work (triage, calendar), that's $50,000 of your EA budget going to work that AI can do in 10 hours.
Step 4: Calculate the Break-Even (Do They Pay for Themselves?)
Formula: Do they pay for themselves? (Hours of time they save you) × (Your hourly value) > (Total cost of EA). Example 1: Founder at $1M revenue, hourly value = $350. Human EA costs $100k/year. Hours freed: Let's say the EA saves you 800 hours/year on: inbox triage (500h), calendar (150h), follow-ups (100h), email drafting (50h). Value created: 800 hours × $350 = $280,000. Cost: $100,000. Net ROI: $180,000. Verdict: Hire the EA immediately. Example 2: Founder at $500k revenue, hourly value = $175. Human EA costs $70k/year. Hours freed: 600 hours (similar work). Value created: 600 × $175 = $105,000. Cost: $70,000. Net ROI: $35,000. Verdict: Hire the EA. It works. Example 3: Founder at $250k revenue, hourly value = $87.50. Human EA costs $70k/year. Hours freed: 500 hours (same work). Value created: 500 × $87.50 = $43,750. Cost: $70,000. Net ROI: -$26,250. Verdict: Don't hire. You lose money.
Step 5: Factor in the AI Economics
An AI executive assistant costs: Setup: $5,000 (one-time, white-glove). Monthly: $500–$2,500 (depending on email volume and complexity). Annual cost: $11,000–$35,000. No hiring. No onboarding. No ramp. No turnover. Work quality from day 1. Let's redo the break-even examples with AI: Example 1: $1M revenue founder. AI cost = $20k/year. Hours freed: 700 hours (AI is slightly more efficient, takes over the pattern work faster). Value: 700 × $350 = $245,000. Net ROI: $225,000. Verdict: Huge winner. Example 2: $500k revenue founder. AI cost = $20k/year. Hours freed: 600 hours. Value: 600 × $175 = $105,000. Net ROI: $85,000. Verdict: Still works. Much better than human EA (simpler onboarding, no turnover). Example 3: $250k revenue founder. AI cost = $20k/year. Hours freed: 500 hours. Value: 500 × $87.50 = $43,750. Net ROI: $23,750. Verdict: Finally works. AI breaks even at lower revenue than human EA.
The Hidden Variables: Scaling and Capability
A human EA can handle ~500 emails per day before they're underwater. At $5M+ revenue, founder inboxes hit 300–500 emails daily. At $10M, it's 500+. A single human EA is now insufficient. You'd need 2. But an AI system handles unlimited volume. As your business scales, a human EA's effectiveness drops. An AI system's effectiveness stays constant. This changes the ROI calculation at scale: At $10M revenue, you'd need 2 human EAs = $200k/year. Or 1 AI system = $25k/year. That's $175k/year difference. Also: A human EA has fixed capabilities (what they learned from 10 years of EA work). An AI system updates with new capabilities monthly. You get better features, better triage, better drafting—without paying extra. By year 3, an AI system has 10x more capability than a human EA, but costs the same.
Decision Framework: Hire When...
Hire a human EA when: Revenue is $1M+. Your hourly value is $500+. You value relationship and judgment over task execution. You're willing to invest in training someone. You have stable, predictable processes. Hire an AI EA when: Revenue is $500K+. You want immediate productivity (no ramp time). You want to scale without hiring headcount. You want flexibility (try it, scale it, pause it—no two-year commitment). You value speed of execution. You need 24/7 availability. Your processes are still evolving. Hybrid approach: Hire both. Use AI for volume work (triage, email drafting, scheduling, follow-ups). Keep a human EA for relationship work, judgment calls, and strategy. This is the setup used by founders at $5M+ revenue. The AI handles 80% of admin. The human EA handles 20% of high-judgment work. Total cost: $100k (AI) + $70k (human) = $170k. But they free up 1,200 hours/year. At a $3,500/hour founder rate, that's $4.2M of value.
