How to calculate the return (ROI) of automating a process
The most common question before automating is whether it pays off. The answer shouldn’t rely on promises, but on an ROI estimate based on your own operations that you can check afterwards.
The basic automation ROI formula
Recoverable hours per year = task volume × minutes per task × automatable share ÷ 60. Multiply those hours by the hourly cost of the people involved and compare it with the initial investment plus annual maintenance and third-party costs.
Illustrative example
With fictional data: 400 invoices a month, 6 minutes each and 50% automatable mean 20 hours a month, about 240 a year. At an internal cost of €25 per hour, gross savings are around €6,000 a year. Subtract project cost from there to get the payback period.
What the formula misses
- Errors avoided and their cost (claims, corrections, duplicate payments).
- Faster response to customers and opportunities not lost.
- Capacity to grow without hiring at the same pace.
Common mistakes when estimating return
- Assuming 100% automation: there are almost always exceptions.
- Forgetting rollout and team training time.
- Not measuring the starting point, which makes results impossible to verify.
How to reduce estimate risk
Measure a real sample before starting, use a cautious automatable share and plan a small first phase. If that phase delivers, expand; if not, you’ve spent little to find out.
