Phillips ROI Model
(Return on Investment in Learning)

What Is the Phillips ROI Model?

The Phillips ROI Model is a framework used to evaluate the effectiveness of training programs by measuring both learning impact and financial return.

It builds on the Kirkpatrick Model by adding a fifth level Return on Investment (ROI) to determine whether a training initiative delivers measurable business value.

In simple terms, it answers a question many learning leaders are asked:

“Was this training worth the investment?”

The Five Levels of the Phillips ROI Model

The model evaluates training across five levels, moving from learner experience to business impact:

1. Reaction

How participants respond to the training experience (engagement, relevance, satisfaction).

2. Learning

What knowledge or skills were gained during the training.

3. Application and Implementation

Whether learners are actually applying what they learned on the job and what may be preventing them from doing so.

4. Impact

The effect of the training on business outcomes such as productivity, quality, sales, or efficiency.

5. Return on Investment (ROI)

A financial calculation comparing the monetary benefits of training to its total cost.

Why the Phillips ROI Model Matters

For many organizations, training is about driving results. The Phillips ROI Model helps learning leaders:

Connect training to business performance
Justify budgets with financial data
Identify what’s working and what’s not
Improve future learning investments
Shift conversations from activity to impact

This is especially important for large-scale or high-visibility programs where stakeholders expect measurable outcomes.

How ROI Is Calculated

At its core, ROI is calculated using a standard formula:

ROI (%) = (Net Program Benefits ÷ Program Costs) × 100

To get there, organizations must:

Collect data before and after training
Isolate the impact of training from other factors
Convert results (like increased sales or reduced errors) into monetary value
Compare those benefits to total program costs

When to Use the Phillips ROI Model

Not every training program requires full ROI analysis. The model is most valuable when:

The program is high-cost or high-impact
Leadership expects business justification
The initiative is tied to strategic goals
You need to demonstrate measurable value

In practice, many organizations apply ROI analysis to a smaller percentage of programs, typically the ones with the largest investment or visibility.

Common Challenges

While powerful, the Phillips ROI Model can be difficult to implement fully. Common challenges include:

Isolating the impact of training from other variables
Converting outcomes into monetary value
Collecting reliable data over time
The time and cost required to perform the analysis

That’s why many organizations use a scaled approach, applying deeper evaluation only where it matters most.

Phillips ROI Model vs. Kirkpatrick Model

Feature	Kirkpatrick Model	Phillips ROI Model
Levels	4	5
Focus	Learning effectiveness	Learning + financial impact
ROI Measurement	No	Yes
Business Alignment	Moderate	Strong

The Phillips model essentially extends Kirkpatrick by answering the financial question: “What did we get for what we spent?”

How This Applies to Modern L&D

As learning teams shift toward performance consulting, the Phillips ROI Model becomes more relevant. It encourages teams to:

Start with business outcomes
Design with measurable impact in mind
Evaluate beyond completion rates and satisfaction scores

In other words, it supports a move from “Did they like it?” through “Did it change anything?” and finally, to “Was it worth it?”

Final Thought

The Phillips ROI Model is one of the most comprehensive ways to evaluate training but its real value isn’t just in the math. It’s in the mindset shift.

When used well, it helps organizations treat learning not as a cost center, but as a driver of business performance.
