# AI automation ROI calculator: hours saved, savings and payback

> AI automation ROI starts with the time a task takes today: tasks per month × minutes per task × hourly cost. Multiply by the share AI can automate, subtract AI running and maintenance costs, and you have the monthly saving. Payback is the one-off build cost divided by that saving. Document processing, data entry, email triage and report writing are common high-ROI candidates.

## Example result (default inputs)

| Input | Value |
| --- | --- |
| Currency | USD ($) |
| Tasks per month | 2,000 |
| Minutes per task today | 12 |
| Fully loaded hourly staff cost | 25 |
| Share of the work AI automates | 70% |
| AI running cost per task | 0.05 |
| Hosting, licences & maintenance per month | 400 |
| One-off build cost (from your quote) | 20,000 |

**Net saving per month: $6,500.** Automating 70% of 2,000 monthly tasks saves about 280 hours and $6,500 a month after AI costs, paying back in 3.1 months.

Pays back in 3.1 months and frees about 1.8 full-time people for higher-value work.

| Metric | Value |
| --- | --- |
| Hours spent today per month | 400 |
| Hours saved per month | 280 |
| Full-time equivalents freed | 1.8 |
| Gross saving per month | $7,000 |
| AI running costs per month | $500 |
| Net saving per year | $78,000 |
| Payback period | 3.1 months |
| 3-year ROI | 1,070% |

### Cumulative net benefit after build cost

| Item | Value | Detail |
| --- | --- | --- |
| End of year 1 | $58,000 |  |
| End of year 2 | $136,000 |  |
| End of year 3 (selected) | $214,000 |  |

- Freed time only becomes savings if it is redeployed to valuable work or avoids new hires.

## How it is calculated

- **Hours saved**: tasks × minutes per task ÷ 60 × automation share
- **Net monthly saving**: hours saved × hourly cost − (tasks × AI cost per task + fixed monthly costs)
- **Payback**: build cost ÷ net monthly saving
- **3-year ROI**: (net monthly saving × 36 − build cost) ÷ build cost

## Processes with the best AI automation ROI

| Process | What AI does |
| --- | --- |
| Invoice and document processing | Reads PDFs and scans, extracts fields, checks them against orders |
| Email and ticket triage | Classifies, routes and drafts replies |
| Data entry between systems | Copies and validates data across CRM, ERP and spreadsheets |
| Report and summary writing | Turns data and notes into first drafts |
| Sales research | Researches prospects and drafts personalised outreach |
| Contract and compliance review | Flags clauses and missing items for a person to check |

## How to pick the first process

1. List repetitive tasks with high volume and clear rules or examples.
2. Measure how long each takes and how many happen each month.
3. Estimate the share AI can handle with human review.
4. Rank by net saving and risk, and pilot the top one.

## Costs to include

- Model usage per task (tokens), which the LLM token cost calculator estimates.
- Hosting, vector databases and integration platforms.
- Monitoring, prompt updates and maintenance.
- Staff time reviewing AI output, reflected in the automation share.

## FAQ

### How do you calculate the ROI of AI automation?

Work out the hours the process takes today, multiply by the share AI will automate and the hourly staff cost, subtract AI running costs, then compare the yearly saving with the build cost.

### What is a good payback period for AI automation?

Many businesses look for payback within 12 months. High-volume processes often pay back faster.

### Does AI automation need human review?

For most business processes, yes — at least for a sample or for low-confidence cases. The automation share should allow for that review time.

### Which tasks should not be automated with AI?

Low-volume tasks, decisions with legal or safety consequences without human oversight, and processes that change constantly.
