Kirkpatrick–Phillips Training ROI: How to Measure Learning Impact (+ Free ROI Calculator)

If you need to prove the value of your training programs, the Kirkpatrick–Phillips ROI Model is the most trusted framework in L&D.
It helps organisations measure learning effectiveness, behaviour change, business results — and ultimately, the financial return on investment (ROI) of training.

In this guide, you’ll learn:

What Is the Kirkpatrick–Phillips Model?

The Kirkpatrick–Phillips Model is an expanded version of the original Kirkpatrick Four Levels of Evaluation.
Jack Phillips added a fifth level — Return on Investment — allowing organisations to quantify the financial impact of learning.

The five levels are:

Reaction – Did learners like the training?
Learning – Did they gain the necessary knowledge or skills?
Behaviour – Did they apply those skills on the job?
Results – Did the organisation experience measurable improvements?
ROI – Did the financial benefits exceed the cost of the training?

This model is widely used because it connects training directly to business performance and financial outcomes.

The Five Kirkpatrick–Phillips Levels Explained

Level 1: Reaction

Measures participant satisfaction, engagement, and perceived relevance.

Why it matters:
Positive reaction increases the likelihood of learning transfer.

Level 2: Learning

Assesses changes in knowledge, skill, or attitude.

Tools:
Quizzes, assessments, simulations, demonstrations.

Level 3: Behaviour

Evaluates whether learners apply new skills on the job.

Signals include:

Reduced errors
Faster completion times
Improved communication
Higher productivity

Level 4: Results

Measures the organisational impact of the training, such as:

Cost savings
Increased output
Improved quality
More revenue
Better retention

Level 5: ROI

Calculates the financial return of the program.

This is where the Phillips ROI Methodology comes into play.

The Training ROI Formula

The standard ROI formula is:

Where:

Total Benefits = Sum of all monetised improvements
Net Program Benefits = Total Benefits – Program Cost

Why Training ROI Is Important

✔ Demonstrates the business value of L&D

Leaders want evidence, not assumptions.

✔ Helps justify investment

Positive ROI strengthens future budget proposals.

✔ Prioritises high-impact initiatives

ROI helps identify which programs deliver the most value.

✔ Makes L&D more strategic

Data links training to organisational goals.

✔ Builds credibility

ROI reporting elevates L&D to a key business partner.

How to Calculate Training ROI (Step-by-Step)

Step 1: Identify performance improvements

Examples:

Time saved
Fewer incidents
Additional sales
Increased efficiency
Reduced operational costs

Step 2: Monetise improvements

Convert benefits into financial values (e.g., £ saved, £ gained).

Step 3: Apply an isolation factor

Training is rarely the only cause of improvement.
Isolation estimates what percentage of improvement is due to training alone.

Example:
If training influenced 50% of improvement:

Step 4: Calculate net benefits

Step 5: Calculate ROI

Apply the formula:

Example ROI Calculation

A customer service training program reduces handling time, saving the business £60,000/year.

Program Cost: £15,000
Isolation Factor: 50%
Adjusted Benefits: £60,000 × 50% = £30,000
Net Benefits: £30,000 – £15,000 = £15,000

That’s a 100% ROI, meaning every £1 invested returned £1.

When Should You Use the Kirkpatrick–Phillips Model?

Use all 5 levels when:

The program is strategic or high-cost
It targets leadership, sales, compliance, safety, or onboarding
Executives expect measurable outcomes
You need to prove financial value

Use levels 1–3 for smaller programs

Not all training requires ROI.
Reserve full ROI analysis for high-impact initiatives.

FAQs

What is the Kirkpatrick–Phillips ROI Model?

A five-level framework for measuring training effectiveness, including financial return.

How do you calculate training ROI?

Use the formula:
(Net Program Benefits ÷ Program Cost) × 100.

Why is ROI important in learning and development?

It proves impact, justifies budgets, and aligns training with business goals.

What is an isolation factor in ROI?

A method to estimate how much of the improvement is a direct result of training.

Can soft skills training produce ROI?

Yes — improvements in productivity, engagement, communication, and quality can all be monetised.
