How to Calculate the ROI of Automation

Start with a measured baseline #

Choose one repeated process. Measure how often it happens, how long it takes and what rework is involved. Use a representative period rather than the busiest day. Identify the people involved and the outcome you want to improve.

A proposed reduction in task time is an assumption until you have tested it. A pilot with real users can show whether the work has been removed or merely shifted to checking, exception handling or another team.

Separate capacity from financial benefit #

Released hours multiplied by an hourly labour cost gives a notional capacity value. It does not mean the wage bill falls by that amount. Ask how the time will be used: reduced overtime, avoided recruitment or extra work with a measurable contribution may support a financial benefit.

If the team simply has more breathing room, that can still matter. Record it as an operational benefit rather than presenting it as cash saved. Avoid counting both the value of released time and the revenue from using the same time.

Include the full cost #

One-off investment can include design, implementation, migration, training, internal staff time and a contingency for uncertain work. Annual costs can include hosting, subscriptions, monitoring, maintenance and support.

Allow for working weeks, adoption, rollout delays and the chance that the process changes. Compare a conservative case with your expected case and test whether the decision still makes sense.

Worked example: capacity is only the starting point #

Illustrative inputs: a task takes 12 minutes and occurs 50 times per working week. A 50% reduction across 48 working weeks releases 240 hours a year. At $50 an hour, the notional capacity value is $12,000.

If only half of that value becomes a financial benefit, the benefit is $6,000. Subtract $100 a month in ongoing costs to get $4,800 annual net benefit before setup. With a $5,000 initial investment, the steady-state payback is 12.5 calendar months and the first-year net result is −$200. These figures exclude tax, financing and inflation.

Use the result to make a decision #

If annual net benefit is zero or negative, there is no payback on those assumptions. Zero setup cost does not produce a meaningful percentage return on initial investment. Operational or risk benefits may still justify a project, but make that reasoning explicit.

Test your own inputs in the Automation ROI Calculator, then review what would need to happen for the assumed benefits to be realised.
