Test the investment assumptions
What value can the business realize?
Enter your own assumptions to compare scenarios. Include review and rework in remaining effort. No costs or investment are preset.
Enter a number within each stated range to calculate the scenario.
Positive capacity is discounted by the capture assumption. Added labor is counted at full hourly value. Constant volume and costs; no discounting or taxes. Inputs stay in this page and are not submitted.
What the calculator measures
The model compares human effort on adopted tasks with the additional cost of operating the AI workflow. It uses a capture fraction to distinguish positive capacity released from value the organization can realize. The model assumes the proposed workflow meets the same accepted-task quality requirement as the baseline.
Eligible tasks are the cases the feature can actually handle. Adoption is the share of those tasks using the proposed workflow. Remaining effort includes human review, correction and fallback averaged across adopted tasks, including attempts that need extra work.
| Input | How to estimate it |
|---|---|
| Baseline minutes | Human effort for a comparable accepted task before the change. |
| Remaining minutes | Human effort after the change, including review and rework. |
| Loaded hourly value | A defensible value for the affected capacity; not automatically cash savings. |
| Capture percentage | The share of positive released capacity that becomes useful value. |
| Additional operating cost | System operation, maintenance and other added costs not already counted in remaining effort. |
| Initial investment | Implementation, integration, migration and other one-time costs in the chosen scope. |
The complete calculation
adopted = eligible tasks × adoption / 100
hours = adopted × (baseline minutes − remaining minutes) / 60
if hours ≥ 0: value = hours × hourly value × capture / 100
if hours < 0: value = hours × hourly value
net = value − additional monthly operating cost
payback months = investment / net, only when net > 0
first-year simple ROI = (12 × net − investment) / investmentThe capture factor discounts only positive capacity. If the new workflow adds labor, that cost is counted at the full hourly value. Payback is not reached when net monthly value is zero or negative. First-year ROI is not defined when the initial investment is zero; a zero denominator should not produce an infinite percentage.
The first-year measure includes twelve months of constant net value and the initial investment. It is an undiscounted scenario calculation. It excludes taxes, financing, growth and the timing of a gradual rollout. Use a more detailed financial model when those effects are material.
Worked example: capacity and financial formulas
Use a synthetic workload of 10,000 tasks, 70% adoption, six baseline minutes and 1.2 remaining minutes. These assumptions release 560 hours per month. If 50% becomes useful capacity, that is the equivalent of 280 hours at the chosen hourly value. Enter your own hourly value, monthly operating cost and investment to calculate the financial outcome.
| Step | Calculation | Result |
|---|---|---|
| Adopted tasks | 10,000 × 70% | 7,000 / month |
| Hours released | 7,000 × (6 − 1.2) / 60 | 560 / month |
| Realized value | 560 × hourly value × capture fraction | Use your measured hourly value |
| Net value | Realized value − monthly operating cost | May be positive or negative |
| Simple payback | Initial investment ÷ positive net monthly value | Months; not reached if net value is nonpositive |
| First-year simple ROI | (12 × net monthly value − investment) ÷ investment | Percent; undefined for zero investment |
At 35% adoption, the same workflow releases 280 hours instead of 560. With 50% capture, the equivalent useful capacity falls to 140 hours. Fixed operating costs do not automatically halve, so net value may fall faster than adoption. Recalculate before treating the initial scenario as an investment case.
Use the result to choose the next experiment
Identify the uncertain input most likely to reverse the decision. A pilot can measure review effort or adoption; an operating discussion can establish whether released time will actually be used. If the result depends on nearly all capacity becoming cash savings, ask what expense or hiring plan would change.
- Compare similar task classes and accepted outcomes.
- Include difficult cases rather than timing only the easiest demo.
- Do not count the same review labor in both remaining minutes and operating cost.
- Model quality losses or additional benefits separately with an explicit attribution method.
- Preserve the original assumptions and compare them with observed results after rollout.

Privacy and practical limits
The calculator performs arithmetic in this page. It does not submit the inputs to a server, analytics event or persistent storage. Reloading the page restores the synthetic example. The formulas and static example remain readable without JavaScript.
The output is a planning aid. It does not validate the task quality, data rights, technical feasibility or organizational change needed to achieve the inputs. Those are separate evidence requirements for the investment decision.
