AI ROI calculator: what an AI agent is worth in your workflow

Work out in two minutes how many hours an AI agent frees up in one process, what that is worth net per year, and which build budget pays back within twelve months.

Your assumptions

01The workflow today

Requests, quotes, complaints or documents a person handles today.

Reading, looking up, deciding, writing back. Excluding waiting time.

Salary, social costs and workplace. Labour costs alone were 49.50 euros an hour in German manufacturing in 2025 (Destatis).

02What the agent takes on

Cases inside the rules. The rest goes to a person as today.

The workflow carries a build. The number that matters most is the share the agent can prepare safely; the assessment measures it on real cases.

Assumptions: 1,600 productive hours per full-time position per year; the saving applies only to the share of cases the agent prepares. Faster answers, fewer errors and more consistent decisions are not included.

How the calculator works

Working time today is cases per month times twelve times minutes per case. The agent saves only on the share of cases it can prepare inside the rules, and there only on the part of the time a person no longer spends searching and writing, because they review and release instead.

Hours saved times fully loaded cost per hour gives the gross saving. Minus the running cost for model usage, hosting, monitoring and refinement, that leaves the net saving. The one-off build divided by the monthly net saving gives the payback in months.

Where to get the numbers

The case count almost always sits in a system already: the ticket system, the ERP as the number of quotes or complaints, the invoice register. Use the average of the last twelve months, not the peak month.

Handling time is best measured rather than estimated: have two people handle ten cases each with a stopwatch and take the median. Waiting time for answers does not belong in it; the agent shortens that in a different way.

The two most uncertain values are the share the agent prepares and the time saved per case. Set them cautiously. These are exactly the two numbers a Workflow Assessment measures on real cases.

WorkflowWhat counts as a caseWhere the volume isWhat drives the time
Service triageOne incoming request by email, portal or phone noteTicket system, service inboxReading, categorising, searching history in CRM and ERP
Quote preparationOne request for quote with its line itemsERP or CRM, quote statisticsMatching items, checking prices and availability

What the calculation does not show

The calculator counts working time only. In many workflows the larger value lies elsewhere: a quote that reaches the customer the same day instead of after four days wins more often. A complaint decided by rule rather than by handler costs less goodwill. An invoice posted correctly saves the correction at month-end close.

On the cost side, the internal time of the business and IT during the build and the support for the people affected are missing. Both can be planned, but neither is zero.

When a dedicated build pays off

As a rule of thumb from the calculation itself: if a workflow frees less than half a full-time position, it rarely carries a build of its own with integration, control set and shadow mode. Then it is worth bundling similar cases from adjacent processes, or starting with a workflow that has more volume.

Conversely, if even the cautious calculation shows a payback under a year, the most expensive mistake is to wait too long with a pilot that never writes back to the system of record.

Questions

Common questions

How accurate is the result?
As accurate as the assumptions. Case count and loaded cost are usually solid; share and time saved are estimates. Run a cautious and an expected variant and decide on the cautious one.
What are the running costs of an AI agent?
Model usage per case, hosting in your cloud, monitoring, and ongoing refinement when rules, systems or model versions change. In most operational workflows model usage is the smaller item; operations and refinement weigh more.
Does the agent replace people?
The calculator shows freed capacity, not positions. In most operations it goes into cases that are left waiting today, faster answers, or growth without new hires.
Does the calculator store my inputs?
No. The calculation runs entirely in your browser. Only if you request a strategy call do we carry the numbers into the form, and only if you submit it.
