Calculate Automation ROI: Formula + Calculator
Calculate automation ROI with our simple formula. Discover manual processing costs and justify your investment in minutes.

You know your team is drowning in manual data entry. You've seen the errors. You've watched employees spend hours typing invoice details into spreadsheets. But when you approach leadership about investing in automation, the first question is always the same: "What's the ROI?"
If you can't answer that question with hard numbers, your automation project is dead in the water.
The good news? Calculating automation ROI is simpler than you think. In this guide, you'll learn the exact formula to prove the business case for document automation—and discover why most teams break even within 3-6 months of implementing solutions like Scanny AI.
Why Most Teams Underestimate Manual Processing Costs
Before we dive into the formula, you need to understand the hidden costs of manual document processing. Most businesses only account for salary costs, but the true expense runs much deeper.

Here's what you're actually paying for when you process documents manually:
| Cost Category | Manual Processing | Automated Processing (Scanny AI) |
|---|---|---|
| Labor Time | 5-10 min per document | 30 seconds per document |
| Error Rate | 3-5% human error | <0.1% AI error |
| Rework Costs | 15-20% of labor time spent fixing errors | Minimal (validation built-in) |
| Opportunity Cost | High-value employees doing data entry | Employees focus on strategic work |
| Scalability | Hire more people = linear cost increase | Process 10x volume with same subscription |
| Compliance Risk | Manual errors = audit failures, fines | Automated audit trails, consistent compliance |
When you add these factors together, the true cost of manual processing is typically 3-5x higher than the visible salary cost alone.
The Simple Automation ROI Formula
Here's the formula that cuts through the complexity:
ROI (%) = ((Annual Savings - Annual Cost) / Annual Cost) × 100
Where:
Annual Savings = (Current Manual Cost per Year) - (Automated Cost per Year)
Annual Cost = Total Investment in Automation Solution
Breaking Down the Components
1. Current Manual Cost per Year
Manual Cost = (Number of Documents) × (Time per Document) × (Hourly Rate) × (Error Multiplier)
Example:
- 500 invoices/month = 6,000/year
- 7 minutes per invoice
- $25/hour employee rate
- 1.2x error multiplier (20% time spent on rework)
Manual Cost = 6,000 × (7/60) × $25 × 1.2 = $21,000/year
2. Automated Cost per Year
For Scanny AI, this includes:
- Subscription cost (based on your plan)
- Setup time (one-time, amortized over 12 months)
- Minimal review time (30 seconds per document)
Automated Cost = Subscription + (Review Time × Documents × Hourly Rate)
Example (Pro Plan at $149/month):
- $149 × 12 = $1,788 subscription
- 6,000 documents × (0.5/60 hours) × $25 = $1,250 review time
- Setup: 4 hours × $25 = $100
Automated Cost = $1,788 + $1,250 + $100 = $3,138/year
3. Calculate Your ROI
Annual Savings = $21,000 - $3,138 = $17,862
ROI = ($17,862 / $3,138) × 100 = 569%
Payback Period = $3,138 / ($17,862/12) = 2.1 months
Key Takeaway: In this real-world example, document automation delivers a 569% ROI with a payback period of just 2.1 months.
Step-by-Step: Calculate Your Automation ROI
Let's walk through the calculation process step by step using your actual numbers.
Step 1: Measure Your Current Manual Process
You need four critical metrics:
A. Document Volume Track how many documents you process:
- Daily: _______
- Weekly: _______
- Monthly: _______
- Annual Total: _______
B. Time per Document Time yourself processing 10 sample documents and calculate the average:
- Finding the document
- Opening and reading it
- Manually extracting data
- Entering data into your system
- Verifying accuracy
Average Time: _______ minutes
C. Fully-Loaded Labor Cost Don't just use base salary. Include:
- Base hourly rate: $_______
- Benefits (typically 30% of salary): $_______
- Overhead (space, equipment, 20% of salary): $_______
Total Hourly Cost: $_______
D. Error & Rework Rate
- Measure error rate on 100 documents
- Calculate time spent fixing errors
- Error Multiplier: _______ (typically 1.15-1.25)

Step 2: Calculate Your Manual Processing Cost
Annual Manual Cost = Documents × (Time/60) × Hourly Cost × Error Multiplier
Your Calculation: _______ × (/60) × $ × _______ = $_______
Step 3: Estimate Your Automated Processing Cost
For Scanny AI:
Subscription Cost (check current pricing)
- Starter ($49/month): Up to 500 documents
- Pro ($149/month): Up to 2,500 documents
- Business ($399/month): Up to 10,000 documents
- Enterprise: Custom pricing
One-Time Setup Cost
- Schema creation: 2-4 hours
- Workflow integration: 2-8 hours
- Testing: 2 hours
Ongoing Review Time
- Average 30 seconds per document for validation
- Documents × (0.5/60) × Hourly Cost
Your Automated Cost: $_______ (subscription) + $_______ (setup/12) + $_______ (review) = $_______
Step 4: Calculate ROI and Payback Period
Annual Savings = $_______ (Manual) - $_______ (Automated) = $_______
ROI = (Savings / Automated Cost) × 100 = _______%
Payback Period = Automated Cost / (Savings/12) = _______ months
Real-World ROI Example: Invoice Processing
Let's look at a concrete example from a mid-sized manufacturing company that implemented Scanny AI for invoice processing.
The Scenario
Company Profile:
- 50-person manufacturing company
- Processes supplier invoices, purchase orders, shipping documents
- 800 documents per month (9,600 per year)
- 2 AP clerks spending 40% of time on data entry
Before Scanny AI:
Manual Processing Costs:
- 800 documents/month × 8 minutes per document = 6,400 minutes/month
- 6,400 minutes = 106.7 hours/month
- 106.7 hours × $28/hour (loaded cost) = $2,987/month
- Error rate: 4% requiring 20 minutes each to fix
- 32 errors/month × 20 minutes = 640 minutes (10.7 hours)
- 10.7 hours × $28 = $300/month in rework
Total Monthly Cost: $3,287
Total Annual Cost: $39,444
After Scanny AI (Pro Plan):
Automated Processing Costs:
- Subscription: $149/month
- Review time: 800 × 0.5 minutes = 400 minutes/month (6.7 hours)
- 6.7 hours × $28 = $188/month
- Setup cost amortized: $400/12 = $33/month
Total Monthly Cost: $370
Total Annual Cost: $4,440
The Results:
Annual Savings: $39,444 - $4,440 = $35,004
ROI: ($35,004 / $4,440) × 100 = 788%
Payback Period: 1.5 months
Time Saved: 1,200+ hours per year

Real Impact: This company recovered their entire annual investment in just 6 weeks and freed up 1,200+ hours—equivalent to adding a half-time employee without any hiring costs.

Beyond the Numbers: Intangible Benefits of Automation
While ROI focuses on hard costs, automation delivers benefits that are harder to quantify but equally valuable:
1. Employee Satisfaction
Data entry is soul-crushing work. When you eliminate it:
- Turnover decreases (recruiting costs: $4,000-$15,000 per employee)
- Productivity increases (employees focus on meaningful work)
- Morale improves (team feels empowered, not like robots)
2. Scalability Without Hiring
Need to process 2x the documents next quarter? With manual processing, you need 2x the staff. With Scanny AI, you upgrade your plan—no hiring, training, or onboarding delays.
3. Competitive Advantage
Faster document processing means:
- Quicker invoice approval = stronger vendor relationships, early payment discounts
- Faster contract processing = close deals faster than competitors
- Real-time data = better business intelligence and decision-making
4. Compliance and Audit Readiness
Automated systems create perfect audit trails:
- Every document timestamped and versioned
- Every extraction logged with confidence scores
- Instant reporting for compliance reviews
- Reduced risk of regulatory fines

Common ROI Mistakes to Avoid
Mistake #1: Only Counting Direct Labor Costs
Fix: Include benefits, overhead, error rework, and opportunity costs.
Mistake #2: Ignoring Setup and Training Time
Fix: Account for 8-16 hours of initial setup (still pays back in weeks).
Mistake #3: Underestimating Document Volume Growth
Fix: Plan for 20-30% annual growth—automation scales, hiring doesn't.
Mistake #4: Not Measuring Before Automating
Fix: Track baseline metrics for 2 weeks before implementation so you can prove ROI.
Mistake #5: Forgetting Soft Costs
Fix: Include compliance risk, employee turnover, and delayed payments in your analysis.
