How to estimate the value of AI training

Measure one workflow before estimating the value of a training program. Include review, corrections, setup, and ongoing costs. Time saved is capacity you may use elsewhere; it is not automatically cash saved.

Establish a baseline

Choose a repeatable task, such as preparing a meeting handoff. Record the active work time for a representative set of examples. Keep the input quality and task difficulty comparable when you test an AI-assisted version.

For each attempt, record:

Task ID:
Manual active minutes:
AI-assisted preparation minutes:
Human review minutes:
Correction minutes:
Accepted or rejected:
Reason for rejection:
Tool/API cost:

Include rejected attempts. Counting only the successful ones makes the workflow look cheaper than it is.

Calculate the difference

AI-assisted active time = preparation + review + corrections
Net minutes released = manual active time - AI-assisted active time
Monthly capacity hours = net minutes released × monthly task count / 60

Keep waiting time separate from active work. If someone works on another task while the model runs, do not charge both tasks for the same minute.

Work through a hypothetical example

These are made-up inputs to demonstrate the calculation, not customer results or a forecast:

Input	Example value
Manual work per task	20 minutes
AI preparation, review, and corrections	12 minutes
Tasks per month	60
Internal hourly cost assumption	$30
Additional monthly tools/maintenance	$40
One-time training and setup	$400

The difference is 8 minutes per task. Across 60 tasks, that is 8 hours of capacity per month. At the assumed internal cost, the capacity value is $240. After $40 in recurring costs, the estimated monthly net value is $200.

If that pattern holds for three months, estimated net value is $600 before the $400 one-time investment. The example’s net ROI is (600 - 400) / 400 = 50%.

This is a capacity-value calculation. It becomes cash savings only if an actual expense falls. If the released time is unused, the benefit is not realized.

Stress-test the result

Change one assumption at a time:

• If review and corrections rise to 22 minutes, the assisted workflow takes longer than the manual one.
• If the task count falls to 15 per month, the same time difference releases only 2 hours.
• If setup or maintenance costs rise, recalculate the investment and recurring costs.
• If errors escape review, include the cost of repair and decide whether the workflow is acceptable at all.

Do not substitute industry benchmarks for your own task data. This page does not claim an average ROI or an implementation success rate.

Decide what to do next

Continue a pilot when the output meets your acceptance rules and the total effort improves. Revise it when the draft is useful but review dominates. Stop when the workflow creates more work or unacceptable errors.

Keep the worksheet and the underlying task records. They let you explain a decision without turning an estimate into a testimonial.

Try a small workflow first or discuss a workshop for your team.
