Direct answer: how to estimate ROI for a pilot

Estimate pilot ROI by measuring current manual hours, error/rework rates, and throughput delays for one workflow, then apply conservative automation savings (20-40%) and compare against the pilot cost over 90-180 days. Start with one process, not a full transformation model.

What to measure before any automation build

Monthly process volume (requests, forms, invoices, tickets, etc.)
Average handling time per item (minutes)
Rework rate and escalation rate
Time-to-completion / cycle time delays
Who must approve or review output
Current software stack (M365, Teams, Outlook, CRM, ERP, ticketing, file stores)

Method rule

Use observed numbers from the last 4-8 weeks, not best-case guesses.

Pilot ROI formula (conservative)

Use this baseline equation for a 30-60 day pilot and 90-180 day payback review.

Metric	Formula	Notes
Monthly hours saved	Volume x Time per item x % reduction	Use 20-40% reduction for first pilot estimates
Monthly labor value (USD)	Hours saved x loaded hourly cost	Include wages, benefits, payroll tax, and reviewer time
Rework savings	Reduced errors x avg rework time x hourly cost	Only include measurable rework
Pilot ROI	(90-180 day value - pilot cost) / pilot cost	Review after pilot stabilizes

Example workflow model: intake and triage

Input	US example	Conservative automation assumption
Monthly submissions	1,200 intake emails/forms	Use recent 30-day average
Current handling time	7 minutes each	Measure across 20-30 samples
Automation savings	30% handling-time reduction	Pilot target for classification + routing
Human review	100% on exceptions, sampled on routine cases	Keep approvals in place during pilot
Outcome to track	Faster routing + fewer missed follow-ups across locations	Tie to service-level target

What a 30-60 day pilot should include

Week 1: process and baseline

Workflow map, exceptions, and approvals documented
Success metrics agreed (hours, turnaround, error rate)
Security/compliance and data handling constraints confirmed

Weeks 2-4: build and test

Automation inside existing tools where possible
Human-in-the-loop checkpoints for all high-risk actions
Exception handling and rollback path documented

Weeks 5-8: supervised rollout

Limited-volume rollout and performance review
Metric review against baseline
Scale / stop / redesign decision based on evidence

What not to do when calculating pilot ROI

Do not assume 80-100% automation on the first pilot
Do not count "strategic value" if you cannot explain the math
Do not ignore reviewer time and exception handling
Do not compare pilot cost to a full-year fantasy scenario

Next step

Use this methodology to score one workflow, then book a pilot scoping session. If you want a faster start, use our What to Automate First scorecard before your consultation. US teams should also define who signs off on exception handling during the pilot.
