MAINNET / AI TIME SAVINGS CALCULATOR

The hour AI
gives back.

A faster draft is only part of the work. Count preparation, review, rework and upkeep to see how much human time your AI workflow could actually release.

01The work today

Use the same recurring task and an accepted result as your starting point. Include the existing review and rework in the baseline.

tasks
Use a representative weekly average.
min
The complete original workflow, across everyone involved.
02The work with AI

Count active human effort. Rework below is extra work after the normal review, so count it only once.

min/task
Gathering inputs, prompting, supervising and handling output.
min/task
Checking every result against the acceptance criteria.
%
Share of tasks that need more work after normal review.
min/task
Total extra correction and rechecking per affected task.
min/week
Shared workflow maintenance, fixes and updates.
03The first commitment

Include all contributors’ setup time. The model holds the weekly task volume and effort constant over your chosen horizon.

hours
Learning, configuration, documentation and testing.
weeks
Whole weeks, including the effect of setup time.

Your inputs stay in this calculator. Copy or print if you want to keep them.

Net human time released each week

3 h 20 min

Under these assumptions, time becomes available each week. Check quality, then decide how that time will be used.

  • Maintenance1 h

Time estimates only. Comparable quality is a separate gate; released hours are not cash savings. Negative results mean additional work.

THE WHOLE WORKFLOW

Make the hidden
minutes visible.

This is a transparent planning model. Replace the example with observed averages, keep the task mix comparable and record uncertainty alongside the result.

01 / WEEKLY HUMAN WORKBefore = tasks × baseline minutes ÷ 60.
With AI = tasks × [preparation + review + (rework % ÷ 100 × extra rework minutes)] ÷ 60 + upkeep minutes ÷ 60.

02 / TIME RELEASEDWeekly net = before − with AI.
Horizon net = weeks × weekly net − setup hours.

03 / SETUP RECOVERYBreak-even weeks = setup hours ÷ weekly net, when weekly net is positive. With no recurring time gain, the setup time is not recovered through this model.

Count person-hours, not just elapsed clock time. If two people each spend ten minutes, record twenty human minutes. Do not add unattended machine time unless it prevents someone from doing other work. Keep that convention consistent in both workflows.

The hour AI gives back — pilot sheet

A SMALL, REAL EXPERIMENT

Try one workflow.
Keep an honest record.

Use two weeks as a starting rhythm: establish the baseline, trial the assisted workflow, then decide. Extend the observation period for rare, seasonal or highly variable work.

The question is not only whether the result arrived sooner. Did the whole job require less human work at an acceptable quality?

Who gets the hour?

Before calling the pilot a success, put the released time somewhere real. A change in the calendar or workload makes the purpose of the experiment visible.

Before trusting the number.

Does “time saved” mean money saved?

No. This tool measures human hours. Cash savings need a separate assessment of actual spending, subscriptions, integration costs and what changes in the business. Released capacity may be useful even when expenditure stays the same.

What if the answer is negative?

The model is saying that review, rework or upkeep exceeds the time removed from the original task. Keep that result. It gives you a specific workflow to improve, reduce in scope or stop.

What about waiting for the model?

Count waiting as human time only when a person is tied up and cannot use it for other work. Count machine runtime separately when assessing costs. Apply the same rule to waiting in the original process.

What if quality changes?

Agree an acceptance threshold before the trial and inspect actual outputs. Compare time only for outputs that meet it. More speed, fewer minutes or a positive break-even cannot establish accuracy or suitability.

Take the question further.
