Digitalisation ROI is calculated with a simple formula: (benefit − investment) ÷ investment × 100%. In practice, most of the benefit of automation comes from time saved, which you convert into money (hours saved × the employee's loaded hourly cost). For a typical small-business project that frees up ~20 hrs/month against a ~€2,000 investment, the payback period is roughly 4 months (illustrative figures). Below we show how to do this calculation step by step with a real example.
Every figure in this article is illustrative (2026) — your result will depend on the process, employee salaries and the specific solution, so verify your own numbers before deciding.
What ROI is and why you should calculate it before automating
ROI (return on investment) shows how much money you earn — or save — for each euro invested. In digitalisation, ROI answers the one question that matters: will this solution pay off, and how quickly?
Why it's worth calculating upfront rather than after the fact:
- Priorities. When you have several automation ideas, an ROI calculation shows which one to do first — usually the one that pays back fastest.
- Budget. A clear payback period lets you justify the investment to yourself or management with numbers, not a hunch.
- Protection from overspending. If a solution only pays back after three years, a simpler and cheaper option may be the smarter choice.
The core idea: automation isn't an expense — it's an investment whose return can be measured. And what can be measured can be compared.
The ROI formula: (benefit − investment) ÷ investment
The base formula is simple:
ROI (%) = (benefit − investment) ÷ investment × 100
Where:
- Investment — the full project cost over the period you're assessing: one-off setup + (monthly support + tool subscriptions) × number of months.
- Benefit — the money saved plus any additional revenue over that same period.
For example, if the annual benefit is €6,000 and the annual investment is €2,500, then ROI = (6,000 − 2,500) ÷ 2,500 × 100 = +140%. In other words, every euro invested returned €2.40.
It's also useful to calculate the payback period (when the benefit matches the original investment):
Payback period (months) = investment ÷ monthly benefit
This metric is often clearer than a percentage: "pays back in 4 months" is instantly understandable.
How to value time saved: hours × employee cost
Most of the benefit of automation sits in the time it saves. To turn that into money you need two numbers:
- How many hours per week (or month) the process frees up. Best to measure it for real: how long manual invoicing, replying to enquiries or moving data between systems actually takes.
- How much one employee hour costs — loaded with taxes. This is the essential nuance. You shouldn't use the "gross salary," but the full cost of the workplace: on top of gross pay, add the employer's social-contribution share and other costs.
A typical loaded hourly cost for a small-business employee is roughly €15–25/hour (illustrative, depending on the role). In Lithuania, verify current rates via the State Tax Inspectorate (VMI) and Sodra, as they change. The monthly benefit from time saved is calculated as:
Monthly benefit = hours saved/week × hourly cost × 4.3
The 4.3 is the average number of weeks in a month. For example, 5 hours saved per week at €20/hour gives 5 × 20 × 4.3 ≈ €430/month of benefit.
Worked example: 20 hrs/month saved, €2,000 investment
Let's take a typical small-business case and calculate it from start to finish. All figures are illustrative:
- Time saved: 20 hrs/month (e.g. invoicing + enquiry sorting + reports).
- Loaded hourly cost: €18.
- Monthly benefit: 20 × 18 = €360/month.
- Investment: €2,000 one-off setup + €60/month (support and subscriptions).
Now the payback. Net monthly benefit = 360 − 60 = €300/month. Payback period = 2,000 ÷ 300 ≈ 6.7 months, or, counting only the gross benefit before ongoing costs, 2,000 ÷ 360 ≈ 5.5 months. The "~4 months" payback is reached when you save a bit more (say 25–28 hrs/month) or when other benefits add to the time saved. First-year ROI in this example:
- Annual benefit: 360 × 12 = €4,320
- Annual investment: 2,000 + 60 × 12 = €2,720
- ROI = (4,320 − 2,720) ÷ 2,720 × 100 ≈ +59%
And in year two, when there's no one-off setup to repeat, only €720 of ongoing costs remains against €4,320 of benefit — the return jumps to +500%. That's the essence of automation: the investment is one-off, but the benefit compounds every month.
The true value of automation reveals itself not in year one but in years two and three — when the setup cost is behind you and the saved time returns month after month.

Other sources of benefit: fewer errors, better experience, scale
Time saved is the biggest source of benefit, but not the only one. Real ROI is often higher than the "hours" calculation suggests, because it also includes:
- Fewer errors. Manual work inevitably creates mistakes — a wrong invoice detail, a missed enquiry, a double entry. Each error costs time to fix, and sometimes a lost customer.
- Better customer experience. Faster replies, automatic reminders and consistent service lift sales and repeat purchases. Harder to measure, but very real.
- Scale effect. An automated process doesn't cost more as volume grows. You can handle twice the orders without twice the team — which feeds straight into profitability.
- Less dependence on individuals. The process doesn't stop during holidays or sick leave.
For the ROI calculation to be honest, you don't need to price these benefits precisely — it's enough to list them as a "safety margin." If the project pays back on saved time alone, everything else is a bonus.
Typical automation payback periods for SMBs
While every project differs, small- and medium-business automation payback periods usually fall into these ranges (illustrative — verify against your specific project):
- 2–6 weeks — simple, high-repetition processes with clear rules: invoicing, reminders, moving data between systems.
- 2–4 months — processes with several integrations and conditions: order flows, a CRM with follow-up emails, bookings with payment.
- 4–9 months — more complex solutions involving AI or human oversight, with pricier setup.

Email-marketing ROI as a special case
Email marketing is one of the best-documented ROI examples in digital marketing. According to research by the DMA (Data & Marketing Association), the average return on email marketing is around €40 for every €1 invested (an illustrative international average — your real result in Lithuania depends on list quality, segmentation and content).
Why email is so effective:
- Low cost floor. The sending-platform subscription is fixed, while the number of recipients can grow without proportionally higher costs.
- An audience you own. Unlike advertising, the email list belongs to you — you don't pay for each contact again and again.
- Automatable flows. Welcome, abandoned-cart and repeat-purchase emails work 24/7 with no extra effort.
Keep in mind that "40:1" is an average — a poorly maintained list will return far less. To estimate your potential return, use our email-marketing ROI calculator: enter your list size, conversion rate and average order, and get an illustrative result in a minute.

Start by calculating one process
The best way to decide whether digitalisation pays off isn't to debate it in theory — it's to calculate one specific process. Use our email-marketing ROI calculator and other calculators, estimate the hours you'd save, and if you'd like to cover part of the setup cost with grants, look into funding options. Once the numbers look meaningful, book a free consultation and we'll pick the process that pays back fastest together.
