Is an AI assistant worth the cost? Here's how to calculate real return on investment.
The Basic Formula
ROI = (Value Generated - Cost) / Cost
For AI assistants:
- Value = Time saved × Your hourly value
- Cost = Subscription + Setup time
Calculating Time Saved
Track time for one week:
- Email management
- Scheduling
- Research
- Data entry
- Other admin
Estimate AI reduction:
- Usually 50-80% for targeted tasks
- Be conservative
Valuing Your Time
What's an hour worth?
- Employees: Salary / 2000 hours
- Freelancers: Billable rate
- Business owners: Opportunity cost
Don't undervalue your time.
Example Calculation
Before AI
- Email: 10 hours/week
- Scheduling: 3 hours/week
- Research: 5 hours/week
- Total: 18 hours/week
With AI (60% reduction)
- Savings: 10.8 hours/week
- Monthly: ~43 hours
ROI
- Time value: $50/hour
- Monthly value: 43 × $50 = $2,150
- AI cost: $99/month
- Monthly ROI: 2,071%
Even being more conservative, the math works.
What's Harder to Measure
Quality Improvements
- Faster responses
- Fewer missed items
- Better research
- More consistent output
Personal Benefits
- Less stress
- Better work-life balance
- Focus on meaningful work
- Sustainable pace
Opportunity Cost
- What could you do with that time?
- Revenue from new clients?
- Projects finally completed?
- Skills developed?
The Real Question
Not "is AI worth it?" But "what is the cost of NOT using AI?"
While you're doing admin, someone else is using AI to move faster.
