To compare AI software pricing, give each candidate the same job, team size and required output. Convert its billing units into that workload, then add setup and human review. Keep the provider’s bill separate from the cost of staff time.
The worked example below compares two fictional plans for five people producing 200 accepted summaries a month. Plan B costs less at that volume. At 600 summaries, Plan A costs less. You can reproduce both budgets in the calculator above and use the same method with a real quote.
Worked example: two plans, one workload
Every price, allowance and performance assumption in this example is invented for teaching. Plan A and Plan B do not represent named products or measured product performance. Amounts are USD before tax. The model assumes the same workload every month for twelve months, with no price changes.
The team needs five people to create draft summaries from supplied internal documents. An accepted summary must preserve the source facts, include the required sections and pass a human check. The example assumes that 80% of generated attempts become accepted results after review. To deliver 200 accepted summaries, budget for 200 ÷ 0.80 = 250 attempts. Both fictional plans bill unsuccessful attempts too.
| Input | Plan A | Plan B |
|---|---|---|
| People who need access | 5 | 5 |
| Minimum paid seats | 5 | 8 |
| Monthly list price per seat | $30 | $10 |
| Billing choice | 20% annual discount; seat subscription paid upfront | Monthly, no discount; cancellable before the next monthly renewal |
| Fixed platform fee | $30/month, billed monthly | $0 |
| Included monthly allowance | 1,000 pooled credits | 200 pooled runs |
| Units per attempt | 2 credits | 1 run |
| Overage | $0.04 per extra credit | $0.40 per extra run |
| Setup | 12 staff hours | 4 staff hours |
| Staff cost used in the model | $30/hour | $30/hour |
| Review effort | 2 minutes per accepted result | 2 minutes per accepted result |
The review allowance includes time spent inspecting rejected attempts, allocated across accepted results. Setup covers configuration, permissions, templates and a trial run. There are no other labour or vendor costs in this simplified example. In a real budget, add preparation, support and handoff effort if they are not already included.
Calculate the expected month: 200 accepted summaries
Plan A needs 250 attempts × 2 = 500 credits, within its 1,000-credit allowance. Plan B needs 250 runs, which exceeds its allowance by 50. Its overage is 50 × $0.40 = $20. The larger credit number on Plan A’s pricing card has meaning only after this conversion.
| Cost component | Plan A | Plan B |
|---|---|---|
| Seat subscription, monthly equivalent | 5 × $30 × 0.80 = $120 | 8 × $10 = $80 |
| Platform fee | $30 | $0 |
| Overage | $0 | $20 |
| Vendor cost, monthly equivalent | $150 | $100 |
| Review labour | 200 × 2 ÷ 60 × $30 = $200 | $200 |
| Setup allocated over 12 months | 12 × $30 ÷ 12 = $30 | 4 × $30 ÷ 12 = $10 |
| First-year monthly equivalent | $380 | $310 |
| First-year total | $380 × 12 = $4,560 | $310 × 12 = $3,720 |
| Cost per accepted summary, including allocated setup | $380 ÷ 200 = $1.90 | $310 ÷ 200 = $1.55 |
Plan B is $840 cheaper over the first year in this scenario. That result includes three paid seats the team does not use. It is still conditional on the assumed acceptance rate and review time, the required features being available, and both plans meeting the same data-handling requirements.
Use Load Plan A example or Load Plan B example above to reproduce the totals. Plan B has eight paid seats, even though only five people work with it. The calculator’s per-seat figure therefore divides by eight; for cost per active person, divide the monthly total by five instead.
When does the cheaper plan change?
Keep the same people, acceptance rate and review minutes, and vary only the required monthly output. Each accepted result needs an expected 2.5 credits on A or 1.25 runs on B. Review costs $1 per accepted result on either plan.
| Accepted summaries/month | Plan A units / overage | Plan B units / overage | Total A / B | Lower modeled cost |
|---|---|---|---|---|
| 80 | 200 credits / $0 | 100 runs / $0 | $260 / $170 | B by $90/month |
| 200 | 500 credits / $0 | 250 runs / $20 | $380 / $310 | B by $70/month |
| 340 | 850 credits / $0 | 425 runs / $90 | $520 / $520 | Equal |
| 600 | 1,500 credits / $20 | 750 runs / $220 | $800 / $910 | A by $110/month |
The first-year crossover is 340 accepted summaries per month under these assumptions. Between 160 and 400 summaries, A is still within its allowance while B is paying overages. If q is the monthly accepted count, A costs $180 + $1q and B costs $10 + $1.50q. Setting those equal gives $170 ÷ $0.50 = 340. Outside that range, recalculate the allowance terms rather than extending the same formula.
At 600 summaries, change A’s expected usage to 1,500 and B’s to 750, and set review time to 20 hours for both. The first-year totals become $9,600 and $10,920. For uneven demand, calculate each month’s overage separately and add setup once; an annual average can hide expensive busy months.
A small review-time difference can reverse the result
At 200 summaries, suppose B actually needs three review minutes per accepted result rather than two. Its review cost rises from $200 to $300, and its monthly equivalent becomes $410. A remains at $380. A trial that measures this extra minute would change the decision even though the subscription prices stayed the same.
This is why the example does not declare a universal winner. Measure quality, billable attempts and total review effort with representative documents before adopting its assumptions. The 30-day pilot checklist can help organize that trial.
Separate budget cost from cash due
A’s $120 seat subscription is a monthly equivalent of a $1,440 annual payment. Its first month therefore involves $1,440 for seats plus the $30 platform fee, with no usage overage at the expected volume. B incurs $80 for seats plus $20 of usage charges for that month, with the overage billed after use in this example.
The $360 of setup labour on A and $120 on B are allocated staff costs. They are not additional invoices from either vendor. If salaried staff do the work within existing hours, those costs represent capacity used; they do not necessarily increase payroll. Keep an invoice/cash view alongside the economic-cost view.
The first-year totals assume twelve months of use. After setup, recurring monthly economic cost at the expected volume is $350 on A and $300 on B. Ignoring new setup and assuming unchanged prices, the crossover then falls to 300 accepted summaries. Do not treat this later-period calculation as a renewal quote.
Turn a real quote into calculator inputs
Record the exact plan, billing currency and date of the quote. Identify per-seat charges, shared platform fees and usage separately. If the pricing page already shows the discounted annual monthly equivalent, enter that amount with a zero discount: applying the discount again understates cost.
Seats and minimum commitments
Use the greater of the seats you need and the minimum you must buy. Check whether reviewers, administrators and guests need paid access. A per-paid-seat average can look attractive when many seats are idle; keep cost per active person visible too.
Credits, runs and acceptance rates
Choose an output you can accept or reject, and define acceptance before testing. Log each attempt, billable units and review time, including failures. Expected attempts equal required accepted outputs divided by the acceptance rate. Different models, input lengths and tasks may consume different units; use separate workload groups where one average would be misleading.
Allowances, packs and caps
The calculator assumes a shared monthly allowance and a linear price for each excess unit. Confirm whether an actual allowance is pooled, per seat or per day. For prepaid packs, round excess usage up to the next whole pack outside the calculator. If a plan stops at its cap, an affordable estimate does not establish that it can finish the workload.
Setup and other recurring costs
Enter internal setup hours and the hourly cost you use for planning. Put fixed monthly platform, storage, integration or support charges in “Other recurring cost.” The calculator has no separate one-time vendor-fee input: add any such invoice to the first-year result outside it and disclose the adjustment. Do not disguise an external invoice as staff time.
Human effort and double counting
Enter the combined review hours for the whole team each month, not hours per person. Include preparation and correction here if you intend to cost them and have not counted them elsewhere. When roles have different hourly costs, calculate their combined labour cost separately or use an explicitly weighted hourly rate.
Use a denominator that describes useful work
Cost per token or generation helps explain consumption. Cost per accepted result helps compare what the team obtains. The FinOps Foundation’s unit economics guidance distinguishes resource measures from business measures and recommends documenting how those measures connect to goals and costs.
Do not divide by attempted outputs when the business needs usable ones. If no output is accepted, cost per accepted output is undefined; report the cost and the failed outcome separately. A lower unit cost also does not make a result worthwhile when it fails accuracy, access, privacy or delivery requirements.
Use the AI tool ROI calculator for the separate question of whether the outcome justifies the expense. Time freed for other work is not automatically cash saved, and the same benefit should not be counted under several overlapping tools.
Questions to settle before committing
- What is due upfront, what is usage-billed later, and what happens at renewal?
- Can paid seats decrease, and when does a cancellation take effect?
- Do unused units expire or roll over, and can all five people use the same pool?
- Do retries, failed tasks, premium models or exports consume additional units?
- Can spending be capped, and does reaching the cap stop work?
- Are the required integrations and data controls included in the quoted tier?
- What export, deletion and migration work would leaving the tool require?
Get answers from the current quote, billing documentation and applicable terms. Leave an unknown marked as unknown rather than treating it as a zero cost. These questions organize a software comparison; they do not interpret a particular contract.
Free trials should answer a cost question
Use a trial to check billable units, acceptance and review effort on the workload you intend to buy. Record the plan and settings: a generous trial allowance or a different model can make its costs unrepresentative of the paid tier. Avoid an annual commitment based only on a polished demonstration.
Check existing access before adding a subscription
Include a tool already available to the team as a candidate if it can perform the required work. Its incremental subscription cost may be zero, but setup and review still belong in the comparison. The 12-point evaluation framework helps decide whether a cheaper candidate meets the requirements before price decides the shortlist.
A reusable quote worksheet
Download the printable AI pricing worksheet (HTML). Open the file in a browser and print it, or copy its fields into your planning document. It includes space for the quote source, paid versus active seats, workload, acceptance, allowances, human effort and excluded costs.
Keep the original quote beside the worksheet. Replace the fictional assumptions with your inputs, calculate low and busy months, and write down which uncertain input could change the decision. Review the budget after the first bill and again when usage or terms change.
AI software pricing questions
Can I compare two tools by their credit totals?
No. In the fictional example, an accepted summary needs 2.5 credits on A or 1.25 runs on B. Compare the cost of the same accepted output, including retries and review, rather than the names or quantities of billing units.
Is an annual discount always the better choice?
No. It reduces the quoted rate in this example but increases A’s upfront commitment. If adoption is uncertain, compare the complete annual commitment with the months you realistically expect to use a flexible alternative.
Does the calculator’s monthly total match my invoice?
It is a first-year monthly equivalent that includes staff review and one twelfth of setup labour. Those are not vendor invoice items. The vendor subtotal shows subscription, usage and other recurring charges on a monthly-equivalent basis; annual prepayment still changes cash timing.
Does choosing another currency convert the amounts?
No. The selector changes the currency symbol only. Enter every amount in the same currency after making any required conversion yourself. Tax, exchange fees and unentered charges are excluded.
Scope and sources
The worked example is a ScoutChoice teaching model with explicit assumptions and reproducible arithmetic. No supplier was tested and no real quote is represented by A or B. It estimates cost, not output quality or financial return. The linked FinOps guidance supports the distinction between resource and outcome measures; it does not endorse this worksheet or its assumptions.
The calculator assumes the entered monthly workload repeats for twelve months, prices stay constant, allowances are pooled and excess units have a linear rate. It does not model prepaid-pack rounding, tier jumps, taxes, foreign exchange or cancellation charges. Use the worksheet to document those adjustments and treat the result as a budget estimate.
