Automation ROI: how to work out whether it's worth it, using your own numbers
25 October 2026 · 6 min read · Dennis Borsos"Is an automation worth it?" is a question nobody answers well from hearsay. Not the supplier who wants to sell to you, and not the neighbour who tried something that didn't work. The right answer comes from your own numbers: how many customers you lose, how much time a task takes, how much the system costs you.
In this article we'll show you how to calculate the ROI of an automation yourself, step by step, with a complete worked example. The figures in the example are hypothetical and are only there to illustrate the calculation. You'll replace them with your own.
What ROI means for an automation
ROI (return on investment) tells you how much you gain relative to how much you've invested. For an automation, we use two simple formulas:
- ROI (%) = (total benefits − total costs) ÷ total costs × 100
- Payback period (months) = implementation cost ÷ (monthly benefit − monthly cost)
The first formula tells you whether it's worth it over a chosen time frame (for example, 12 months). The second tells you how long it takes to get back the money you invested up front. For an SME, the second is often more important, because it shows how long your money is "tied up".
Step 1: Calculate the benefits
An automation usually brings in money in three ways. Not all of them apply to every project, but it's worth checking each one.
Recovered revenue
Customers you used to lose and now don't: calls nobody answered, messages received overnight and forgotten, quote requests that waited too long. The formula:
Monthly recovered revenue = lost enquiries per month × conversion rate × average profit per order
Be careful: use profit (margin), not the total order value. If a €100 order leaves you €30 after costs, it's €30 that goes into the calculation.
Time saved
The hours your people no longer spend on repetitive tasks: answering the same questions, copying data, sending confirmations. The formula:
Monthly saving = hours saved per month × total hourly cost of the employee
Be honest with yourself: time saved is only worth money if it's used for something else useful (selling, serving customers, growing the business). If not, it's comfort rather than profit, and it's fairer to list it separately.
Costs avoided
Commissions, errors or hires you no longer need to make. A real example: a hospitality client in Cluj takes direct bookings through its own AI agent instead of paying booking platforms a commission of around 20%. There, the benefit is simple to calculate: the value of direct bookings × the commission avoided.
Step 2: Calculate the costs
Costs have two components:
- Implementation – paid once (usually in instalments tied to deliverables). As a guide, Neurotech's public prices start, excluding VAT, from €800 for a WhatsApp chatbot, €1,200 for a process automation, €1,500 for an AI voice agent and €2,500 for a custom ERP/CRM.
- Monthly costs – AI model usage, telephony, hosting, maintenance. These depend directly on volume, so ask your supplier for an estimate based on your actual number of calls or messages.
Don't forget internal costs: your time and your team's for preparation, the pilot and adjustments. They aren't large, but they exist.
Step 3: A complete worked example (hypothetical)
Please note: all the figures below are made up for the example. They aren't the results of a real client and they aren't a price quote. Use them only as a model for the calculation.
Let's take a hypothetical service business that gets a lot of calls and misses some of them at peak times. It wants an AI voice agent to pick up the missed calls.
Starting data (hypothetical)
| Metric | Value in the example |
|---|---|
| Missed calls per day | 10 |
| Call-to-order conversion rate | 30% |
| Average profit per order | €12 |
| Working days per month | 25 |
| Time saved on the phone | 1 hour a day |
| Total hourly cost of the employee | €8 |
| Implementation cost | €2,000 |
| Monthly running cost | €200 |
Calculating the benefits
- Orders recovered per day: 10 × 30% = 3 orders.
- Profit recovered per day: 3 × €12 = €36.
- Profit recovered per month: €36 × 25 = €900.
- Time saved per month: 1 hour × 25 days × €8 = €200.
- Total monthly benefit: €900 + €200 = €1,100.
Payback period
Net monthly benefit: €1,100 − €200 = €900. Payback period: €2,000 ÷ €900 ≈ 2.2 months.
ROI over 12 months
- Total benefits: €1,100 × 12 = €13,200.
- Total costs: €2,000 + €200 × 12 = €4,400.
- Net gain: €13,200 − €4,400 = €8,800.
- ROI: €8,800 ÷ €4,400 × 100 = 200%.
Step 4: Run a pessimistic scenario too
A serious calculation doesn't stop at the good scenario. Let's assume, again hypothetically, that the conversion rate is only 15%, not 30%:
- Orders recovered per day: 10 × 15% = 1.5.
- Profit recovered per month: 1.5 × €12 × 25 = €450.
- Total monthly benefit: €450 + €200 = €650.
- Net monthly benefit: €650 − €200 = €450.
- Payback period: €2,000 ÷ €450 ≈ 4.4 months.
- ROI over 12 months: (€7,800 − €4,400) ÷ €4,400 × 100 ≈ 77%.
Even in the pessimistic scenario, the investment in the example pays for itself in under six months. If your pessimistic scenario comes out negative, that's a sign the automation isn't a priority yet, or that it needs to be approached differently.
Where to get your real numbers
- Missed calls: from your phone system's call history or your telephone provider.
- Unanswered messages: for a week, count the messages received after hours or answered only several hours later.
- Conversion rate: how many of the calls you answer today turn into orders. If you don't know, keep a note for a week.
- Profit per order: from your accounts or a cautious estimate of your margin.
- Time spent: ask your team to note down, for a few days, how long they spend on the phone or on WhatsApp with repetitive questions.
A week of measurements gives you far better numbers than any estimate from memory.
Common mistakes when calculating ROI
- Using the order value instead of profit. The result looks spectacular, but it's wrong.
- Forgetting monthly costs. Implementation is only part of the cost.
- Counting time saved that isn't put to use. It's a real benefit, but it isn't money in the bank.
- Only calculating the optimistic scenario. Always do the cautious version too.
- Not measuring after launch. The calculation beforehand is a hypothesis. Only the pilot figures tell you the truth.
Test the hypothesis with a pilot
The best way to validate an ROI calculation is a limited pilot lasting a few weeks, with clear measurements: how many calls or messages the system handled, how many became orders, how many were transferred to a person. After the pilot, you redo the calculation with real figures and decide whether to expand.
As a real-world reference: a chain of patisseries in Sibiu recovers around 20 calls a day with an AI voice agent and a custom ERP. For them, the first line of the calculation, missed calls, was already clear before the project started.

Frequently asked questions
How do you calculate the ROI of an automation?
ROI is calculated as the difference between total benefits and total costs, divided by total costs and multiplied by 100. Benefits include recovered revenue, time saved and costs avoided. Costs include implementation and monthly running costs, over the same time frame, for example 12 months.
How long does it take for an automation investment to pay for itself?
It depends on your numbers. The payback period is calculated by dividing the implementation cost by the net monthly benefit, meaning the monthly benefit minus the monthly cost. When an automation recovers customers you were losing every day, the period can be a few months. Always calculate a pessimistic scenario too, so you can see the risk.
Which costs should be included in an ROI calculation?
The one-off implementation cost and the monthly costs: AI model usage, telephony, hosting and maintenance, which depend on volume. Add the internal time spent on preparation and the pilot too. Leaving out monthly costs is the most common mistake, because it makes the ROI look higher than it is.
Why should I use profit rather than order value?
Because a recovered order doesn't put its full value in your pocket, only the margin left after the cost of materials, delivery and labour. If you use the total value, the ROI comes out artificially inflated and you could make the wrong decision. Use a cautious estimate of profit per order.
What if I don't have data on missed calls?
Measure for a week. Check your phone system's or telephone provider's history for missed calls, count the messages that were answered late and ask your team to note how much time they spend on repetitive questions. A week of real data is worth far more than an estimate from memory.
