Issue #6: Why “Hours Saved × Salary” Is Not AI ROI

TL;DR

Most AI ROI formulas are misleading, not just incomplete.
AI projects fail often, but that’s not a bug, it’s part of the model.
The biggest AI costs are ongoing and usually hidden.
The biggest AI benefits don’t show up neatly on spreadsheets.
Simple ROI calculators are useful, but only as a starting point.
Simple ROI calculators are useful, but only as a starting point.

1.0 The “80% Failure Rate” Problem Isn’t What You Think

You’ve probably seen the stat:
80% or more of AI projects fail.

At first glance, that looks like a red flag.
In reality, it’s closer to R&D economics than traditional IT.

AI should be treated like a portfolio, not a single project:

Some experiments fail
A few succeed
The winners pay for the rest many times over

The mistake leaders make is expecting every AI project to justify itself in isolation. That’s not how AI works at scale.

2.0 Your Real AI Costs Are Mostly Invisible

Most ROI models only count:

Software licenses
Initial setup

That’s the tip of the iceberg.

The real costs usually sit here:

Data readiness
Cleaning, labeling, governance, and infrastructure never stop.
Ongoing maintenance
Models drift. Data changes. Performance degrades. If you don’t maintain it, ROI erodes quietly.
Usage-based pricing
Tokens, API calls, credits, multipliers. Costs rise after adoption, not before.
Security and governance
New risks mean new controls, audits, and processes.

AI rarely eliminates cost.
It moves cost.

3.0 The Most Valuable Gains Don’t Fit in Excel

Efficiency gains are easy to measure.
They’re also the smallest part of AI’s value.

The real gains show up elsewhere:

Better employee experience
Faster decision-making
Higher customer satisfaction
Increased experimentation
Faster innovation cycles

These benefits compound over time, but they don’t slot cleanly into a quarterly ROI cell.

Many AI tools look “uneconomic” on paper, yet quietly reshape how a business competes.

4.0 AI Also Introduces New Risk (That Has a Cost)

AI doesn’t just reduce risk.
It changes your risk profile.

Examples:

Biased outputs
Privacy exposure
Regulatory penalties
Hallucinated decisions
Latency or reliability failures

These risks have real financial consequences, even if they’re hard to model upfront.

Any serious ROI discussion has to include:

What risk is reduced
What risk is introduced
What the downside costs look like

Ignoring this is how projects blow up after launch.

5.0 You’re Measuring Productivity Savings Wrong

The most common AI ROI math looks like this:

Hours saved × employee cost

That’s a tactical view.

The strategic view is different.

AI often enables work that was never done before because it was too slow, too expensive, or simply impossible.

That’s not “cost savings.”
That’s new value creation.

If AI allows:

Faster analysis
Deeper insights
More frequent decisions
Better personalization

Then the value is not the time saved.
It’s the outcome unlocked.

6.0 Where a Simple ROI Calculator Does Help

There is a place for simple ROI math.

A calculator based on:

Hours saved
Resource costs
Volume of work

is useful for:

First-pass prioritization
Comparing opportunities
Getting buy-in
Sanity-checking assumptions

We built a simple AI ROI calculator for exactly this purpose:

👉 AI ROI Calculator (Hours & Resource Based)

It’s intentionally simple.
It helps you start the conversation, not finish it.

Complex AI initiatives require broader thinking than any single formula.

7.0 A Better Way to Think About AI ROI

Instead of asking:
“What’s the ROI of this AI tool?”

Ask:

What capability does this create?
What decisions become faster or better?
What work becomes possible for the first time?
What risk is reduced or introduced?
How does this compound over time?

AI ROI is not a line item.
It’s a strategic capability curve.
