The subscription is
only one part of the cost.
Compare two hypothetical workflows, include the time you spend checking their output, and record a small trial before you choose. Replace the example numbers with your own assumptions.

This model combines monthly fees, estimated review labor and an allocation of one-time setup costs. It does not measure output quality, reliability, privacy or fit, and its total is not a prediction of your invoice.
Compare a month of work.
Use the same number of tasks and the same value of your time for both candidates. Usage cost is your estimated charge per completed task, after allowing for credits, retries or extra attempts that apply to your workflow.
| Cost component | Tool A | Tool B |
|---|---|---|
| Subscription | $20.00 | $35.00 |
| Tasks × usage cost | $0.00 | $0.00 |
| Review hours × hourly value | $200.00 | $50.00 |
| Setup cost ÷ allocation months | $0.00 | $0.00 |
| Modeled total | $220.00 | $85.00 |
Under these assumptions, Tool B models $135.00 less per month than Tool A.
This is a cost difference, not a product verdict. Test the quality and acceptance rate with a real task before treating review time as a saving.
Why the example comes to $220 and $85.
These are invented teaching inputs, not prices for named products. Both workflows complete 100 tasks per month, review time is valued at $30 an hour, and setup is allocated across six months.
+ (tasks × review minutes ÷ 60 × hourly value) + (one-time setup cost ÷ months)
Tool A: $20 + (100 × $0) + (100 × 4 ÷ 60 × $30) + ($0 ÷ 6) = $220 per month.
Tool B: $35 + (100 × $0) + (100 × 1 ÷ 60 × $30) + ($0 ÷ 6) = $85 per month.
The higher subscription adds $15, while five fewer review hours subtract $150 in modeled labor, leaving a $135 difference. That reasoning only holds if your trial supports the review times and both workflows meet the same acceptance criteria.
If setup costs $120, allocating it over six months adds $20 per modeled month; over twelve months it adds $10. The underlying $120 payment remains a one-time cost. Taxes, exchange rates, discounts, cancellation costs and costs you do not enter are outside this simple model.
Attach evidence to the estimate.
Pick a small, representative task. Write the acceptance criteria first, run the same input through both workflows, and count the work required to reach an acceptable result. The export combines your notes, assumptions and calculated subtotals.

Use the result to ask better questions.
- Verify the billable unit. Check whether usage is charged per seat, request, token, credit or output. Convert your expected usage into an effective cost per completed task before entering it here.
- Measure the human work. Include checking, corrections, reruns and getting the result into the next step of your workflow. Repeat enough tasks to see whether one unusually good output is distorting the estimate.
- Keep quality visible. Record rejected outputs and requirements that remain unmet. A workflow can be inexpensive and still fail the job.
- Test a busy month. Change the volume and review-time assumptions. Watch whether variable charges or additional human work overturn your first comparison.
- Keep an exit path. Record export options, cancellation terms and the effort of moving to another tool. Revisit the worksheet when pricing or your task changes.
