Calculate the ROI of AI Lease Abstraction
AI lease abstraction costs $20 per lease and takes under 3 minutes. Manual abstraction costs $150–$300 per lease and takes 3–5 hours. This calculator shows the time and cost savings of switching from manual to AI-powered abstraction.

The Formula
Savings = (Manual Cost per Lease − AI Cost per Lease) × Number of Leases
Does not include the cost of reviewer time for AI output validation (typically 15–30 minutes at your internal labor rate). Even with validation, AI abstraction is cheaper than manual at any volume above 1 lease per year.
Worked Example
Example Inputs
| Number of Leases | 50 leases/year |
| Manual Abstraction Cost | $200/lease (paralegal labor) |
| AI Abstraction Cost | $20/lease (Lextract) |
| Reviewer Time (AI validation) | 20 min/lease at $75/hour = $25/lease |
| Manual Abstraction Time | 4 hours/lease |
Result
$7,750 annual savings; 200 hours of paralegal time recovered

Frequently Asked Questions
How much does professional lease abstraction cost?
Manual lease abstraction by US-based paralegals costs $150–$300 per lease. Offshore managed services cost $30–$75 per lease with 1–3 day turnaround. AI-powered abstraction (Lextract) costs $20 per lease with under 3 minute turnaround, though you should budget 15–30 minutes of internal reviewer time to validate confidence-flagged fields.
How do I calculate the ROI of lease abstraction software?
ROI = (Annual Manual Cost − Annual AI Cost − Annual Review Labor) / Annual AI Cost. At 50 leases per year: ($10,000 − $1,000 − $1,250) / $2,250 = 344% ROI. The savings increase at scale — at 200 leases/year, the cost savings exceed $31,000.
