Lesson 4. Impact Calculation#
Goal: calculate how much the agent saves or earns for the business.
Types of Impact#
1. Time savings
The agent automates a task → frees up employee time.
Formula:
Time saved (hours/month) = Manual task time - Time with agent
Example (support bot):
- operators answer 500 questions/month manually
- each question takes 5 minutes
- total: 500 × 5 = 2,500 minutes = ~42 hours/month
- agent answers 80% of questions (400 questions)
- savings: 400 × 5 = 2,000 minutes = ~33 hours/month
In money:
- operator salary: $3,000/month (160 working hours)
- cost per hour: 3,000 / 160 = $18.75/hour
- savings: 33 hours × $18.75 = $618.75/month
- Annual savings: 618.75 × 12 = $7,425
2. Conversion growth
The agent improves the process → more clients convert to customers.
Formula:
Additional revenue = (New conversion - Old conversion) × Traffic × Average order value
Example (lead qualification):
- current conversion: 10% (10 out of 100 leads buy)
- after agent: 13% (+3 percentage points)
- traffic: 1,000 leads/month
- average order: $25,000
- additional sales: (0.13 - 0.10) × 1,000 = 30 sales/month
- Additional revenue: 30 × $25,000 = $750,000/month
3. Cost reduction
The agent is cheaper than manual work.
Formula:
Cost reduction = Manual costs - Costs with agent
Example (email automation):
- manual costs: marketer spends 10 hours/week on emails, salary $4,000/month (160 hours)
- cost per hour: 4,000 / 160 = $25/hour
- email costs: 10 hours/week × 4 weeks × $25 = $1,000/month
- costs with agent: $100/month (OpenAI API + n8n.cloud)
- Cost reduction: 1,000 - 100 = $900/month
- Annual reduction: 900 × 12 = $10,800
How to Calculate ROI (Payback)#
ROI (Return on Investment) — how long until the agent pays for itself.
Formula:
ROI (months) = Development cost / (Monthly savings or revenue)
Example:
- agent development cost: $6,000
- monthly savings: $618.75 (from example above)
- ROI = 6,000 / 618.75 = 9.7 months
Conclusion: the agent pays for itself in 10 months.
Good ROI: 3–12 months (if longer — not attractive for the client).
Impact Calculation Template#
# Impact Calculation: [Agent Name]
## Current situation (without agent)
- Task: [what's done manually]
- Time: [hours/month]
- Cost: [$/month] (employee salaries)
- Conversion: [%] (if applicable)
## With agent
- Time: [hours/month] (how much is automated)
- Cost: [$/month] (tool subscriptions, API)
- Conversion: [%] (if applicable)
## Impact
- Time saved: [hours/month]
- Money saved: [$/month]
- Conversion growth: [%]
- Additional revenue: [$/month] (if applicable)
## ROI (payback)
- Development cost: [$]
- Savings/revenue per month: [$]
- ROI: [months]
**Conclusion:** the agent pays for itself in [X] months, annual savings will be [Y].
