Automation ROI calculator
Automation ROI is the annual operating cost recovered, less what the automation costs to build and maintain. Evaluate general workflows, Accounts Payable (AP) straight-through processing, or enterprise RPA bot fleets with GAAP fully-loaded labor burden rates. All assumptions are editable on screen, and every figure is reconstructable.

Sensitivity matrix
Automation efficiency is rarely 100% predictable in advance. Here is the financial model stress-tested across four efficiency outcomes:
| Efficiency | Recovered | Payback | 3-year net |
|---|---|---|---|
| 40% | $40,804 | 17.0 mo | $50,412 |
| 55% | $56,105 | 11.5 mo | $96,316 |
| 70% (Base) | $71,407 | 8.7 mo | $142,220 |
| 85% | $86,708 | 6.9 mo | $188,124 |

The arithmetic
Every formula, and where it comes from
A figure you cannot reconstruct is a figure you cannot defend in a budget meeting. Here is the mathematical audit trail for each model.
1. General Process
- Base Hours: People × Hours/Wk × 46 wks.
- Rework Overhead: Base Hours × Rework% × (Mins ÷ 60).
- Hours Recovered: (Base + Rework) × Efficiency%.
- Gross Savings: Recovered Hours × Loaded Hourly Rate.
- Payback Horizon: Build Cost ÷ Monthly Net Operating Surplus.
2. AP Invoice Model
- STP Processing: Invoices × STP% at automated unit rate ($2.40).
- Manual Touches: Invoices × (1 − STP%) at manual unit rate ($14.50).
- Dispute Avoidance: Automated 3-way matching stops line variance.
- Early Payment Capture: 2/10 Net 30 vendor discounts captured via 3-day approval.
- Net AP Surplus: Processing + Dispute + Discount gains − Run Cost.
3. RPA & FTE Burden
- Fully Loaded FTE: Base Salary × (1 + 28% Burden Rate).
- Annual Repetitive Time: FTEs × Daily Hours × 5 × 46 wks.
- FTE Capacity Liberated: Recovered Hours ÷ 1,840 annual working hours.
- Bot Fleet TCO: Software Licenses ($1,800/bot) + Host VM Infra.
- Strategic Redeployment: Liberated labor redirected to revenue tasks.
Read this before you quote the number
What this calculator does not capture
It models one process in isolation. Four things it cannot see, each of which has sunk automation programmes that looked fine on a spreadsheet.
Recovered hours are not recovered cost
Unless headcount changes or the time is redeployed to something that earns, the saving stays theoretical. Finance will ask this first. Have an answer.
Exceptions are where automation dies
The 70% that automates is the easy 70%. What remains is every edge case, and it needs a person who still understands the process well enough to handle it.
Automation is a system you now own
It breaks when a source changes, an API version retires, or a rule moves. The run cost above should include somebody keeping it alive, not only licences.
Automating a broken process keeps it broken
If the process is wrong, this makes it wrong faster and at lower cost per error. Fix the process, then automate what is left.
Frequently Asked Questions
How do you calculate Industrial and Manufacturing automation ROI?
Industrial automation ROI measures financial returns across two critical plant levers: unplanned downtime prevention and scrap material recovery. Downtime savings quantify the hours of line stoppages avoided multiplied by the fully loaded hourly machine downtime cost ($500 to $2,500+/hour in manufacturing). Scrap recovery calculates raw material waste eliminated through automated inline sensors and closed-loop PLC precision.
How do you calculate automation ROI?
Automation ROI is the annual operating cost recovered, less the cost to build and run the automation. Recovered cost is the hours the process consumes each year, multiplied by the share automation removes, multiplied by the fully-loaded hourly cost. Payback is the one-off build cost divided by the monthly operating surplus once running.
How do you calculate Accounts Payable (AP) automation ROI?
AP automation ROI compares the baseline manual processing cost per invoice ($12 to $18 for manual data entry, 3-way matching, and exception routing) against automated straight-through processing ($2 to $3.50 with AI OCR). Total returns also factor in avoided dispute investigation overhead and 2/10 Net 30 early payment discounts captured by reducing cycle time from 21 days to under 3 days.
What is the standard labor burden rate in an RPA FTE calculation?
In enterprise financial modeling, the standard GAAP labor burden rate is 28% above base salary. This covers mandatory employer payroll taxes, healthcare contributions, 401(k) matches, paid leave, and physical/IT workstation overhead. Billable rate calculations that omit the 28% burden understate actual cost recovery by nearly a third.
What is a good payback period for process automation?
Most organisations look for payback inside 12 to 18 months. The more important question is whether the process will still exist in its current form by then: automating a process due to be replaced produces a payback figure that never arrives.
Why does the calculator use 46 working weeks instead of 52?
Statutory leave, public holidays and sickness mean nobody works 52 weeks. Calculators that bill a full year overstate the recovery by roughly 12 per cent, which is usually enough to flip a marginal business case.
Do recovered hours translate into real savings?
Only if headcount changes or the recovered time is redeployed to work that earns. Otherwise the saving stays on the spreadsheet. This is the first question a finance director asks about an automation business case, and it should be answered before the case is submitted.
What percentage of a process can automation realistically remove?
It depends on how many exceptions the process carries. Highly structured, rules-based work can reach 80 to 90 per cent. Work involving judgement, unusual documents or frequent exceptions is often closer to 40 to 60 per cent. This is the single input most business cases get wrong, which is why the calculator shows the result across a sensitivity range rather than a single figure.
If the number holds up
Bring the process, not the spreadsheet
Ninety minutes with the engineer who would build it. We go through the process as it runs today, where the exceptions actually are, and whether the share you assumed is the share you will get. If it does not pay back, we will tell you that.
