Core formula: ROI (%) = (Annual benefit − Annual cost) ÷ Total cost × 100. Payback = Upfront cost ÷ Net monthly benefit.
Step 1: Calculate Benefits
Time saved
Hours per transaction × Transactions per month × 12 × Cost per hour
Error reduction
Errors per year × Average cost to fix one error
Other benefits: avoided penalties, faster cash flow, capacity redirected to higher-value work.
Step 2: Calculate Costs
- Initial development (design, build, test).
- License/infrastructure (per year).
- Maintenance (UI changes, monitoring).
- Training and change management.
- Internal cost: team time spent giving input.
Worked Example (Illustration, replace with your numbers)
Say invoice entry:
- 8 minutes per invoice, 1,500 invoices/month → 200 hours/month.
- Staff cost per hour: IDR 40,000 → IDR 8,000,000/month → IDR 96 million/year.
- The bot handles 85% → benefit ≈ IDR 81.6 million/year (the rest are manual exceptions).
- First-year cost (build + license + maintenance) = say IDR 60 million.
- First-year ROI = (81.6 − 60) ÷ 60 = 36%; payback ≈ 9 months.
These figures are only a calculation example, not a price quote or a promise of results.
Commonly Missed Hidden Costs
- Maintenance when the target application changes.
- Time spent handling exceptions.
- Monitoring and on-call.
- Security policy changes (MFA, captcha).
- Documentation and handover.
Tips for a Realistic ROI
- Use 2-4 weeks of actual data, not guesses.
- Use a conservative scenario (70-80% automation rate).
- Choose high-scoring processes (checklist).
- Avoid common implementation mistakes.
FAQ
What is a reasonable payback period?
It depends on volume and complexity; many companies target under 12 months for a pilot.
Is ROI only about cost savings?
No. Speed, accuracy, and compliance also have value, though they are harder to quantify.
