How it works.

  1. 01

    Describe the process

    How many times a month the task runs and how many minutes a person spends on it each time, including checking and copying data between systems.

  2. 02

    Price an hour of work

    Use the loaded hourly cost: salary plus benefits, taxes and overhead. The default is the US private-industry average from the BLS.

  3. 03

    Be honest about coverage

    Set the share of tasks the automation will fully handle. Exceptions and edge cases still go to people, so 100% is rare.

  4. 04

    Add build and running costs

    The one-off build and the monthly cost of model usage, hosting and monitoring. The result updates as you type.

What makes an automation pay back fast

Volume beats sophistication. A modest automation on a task that runs thousands of times a month pays back faster than a clever agent on a task that runs twenty times. The strongest candidates are repetitive, rule-heavy and text-heavy: reading invoices and emails, classifying tickets, extracting data from documents, updating a CRM after a call, or answering the same customer questions.

Coverage matters as much as volume. Most real processes have a long tail of exceptions, so plan for a share automated well below 100% and design a clean handoff to people. A system that handles 60% of cases reliably and routes the rest is worth more than one that attempts everything and needs checking every time. Our AI agent development and business process automation work starts from exactly this split.

What this calculator does not count

It counts time saved, not the value of what people do with that time, faster response times, fewer errors or better customer experience. Those are often larger than the labour saving but harder to price, so leave them out of the payback and list them separately in a business case.

It also assumes savings start on day one after the build. In practice there is a ramp: a pilot on part of the volume, tuning, then full rollout. If you want a cautious figure, lower the share automated for the first months or add a month or two to the payback.

AI automation ROI questions, answered

Something else on your mind? Ask a consultant and get a reply within one business day.

How do you calculate the ROI of AI automation?

Multiply monthly task volume by minutes per task and the share the automation will handle, convert to hours and multiply by the loaded hourly cost. That is the gross monthly saving. Subtract running costs to get the net saving, then divide the build cost by the net saving for the payback period in months.

What is a good payback period for an automation project?

There is no universal threshold, but many teams want a payback inside the first year for operational automation, because process and tooling change quickly. If the calculator shows more than 18 to 24 months, look for a higher-volume process or a smaller first version.

Should I use salary or loaded cost per hour?

Loaded cost. An hour of an employee's time costs more than salary divided by hours, because employers also pay benefits, payroll taxes, equipment and overhead. The default of $47 is the US private-industry average total compensation per hour worked from the BLS.

What share of a process can AI realistically automate?

It depends on how structured the inputs are and how costly mistakes are. Document extraction and classification often reach high coverage with a human review step for low-confidence cases. Judgement-heavy work such as complaints or approvals is usually assisted rather than fully automated. A pilot on real data is the only reliable way to know.

What goes into the running cost?

Model or API usage, hosting, vector database or storage, monitoring and logging, and some maintenance time to update prompts, rules and integrations as your systems change. Usage-based model costs scale with volume, so estimate them per task and multiply.

Does this include the cost of people reviewing AI output?

Only indirectly. If people still review every automated case, that time is not saved, so lower the share automated accordingly. For example, if review takes a third of the original time, a 60% share effectively becomes 40%.

Is AI automation different from RPA?

Classic robotic process automation follows fixed rules on structured screens and data. AI adds the ability to read unstructured text, documents and conversations and to decide what to do next. Many production systems combine both: AI to understand the input, deterministic automation to act on it.

How accurate is this calculator?

It is exactly as accurate as the inputs, because it is plain arithmetic with no hidden benchmarks. The biggest uncertainty is usually the share automated, so try a cautious and an optimistic value and compare the payback for each.

Can I share or save my result?

Yes. Your inputs are stored in the page address, so copying the link reproduces the same result. You can also unlock the full report and print it or save it as a PDF.

Can Nexzem build the automation?

Yes. We build AI agents, document processing and workflow automation connected to your existing tools. Share the process on the contact page and we will suggest a first version scoped for a fast payback.
