How to Measure Training ROI: Formula, Example and the Kirkpatrick Model

What training ROI is, and what it is not

Training ROI answers one question: did the monetary benefits of this program meet or exceed its costs? It is the last step in a chain. People react to a program, learn something, apply it on the job, and the business gets a measurable result. ROI puts a dollar figure on that result and compares it to what you spent.

That makes it different from training effectiveness. A program can be effective, meaning people learned and changed how they work, and still have a low ROI because it was expensive or the result was small. A program can also look great on a satisfaction survey and change nothing at all. ROI is the strictest test, which is why it is worth running only on some programs. More on that below.

This article is part of our guide to employee training and development, which covers the four questions to ask about any program. Here we go into the full calculation.

The training ROI formula

The ROI Institute uses two standard financial calculations:

Both use the same two inputs. The benefits are business results converted to dollars, counting only the share the training caused. The costs are fully loaded, meaning every cost of the program, not just the course fee.

Kirkpatrick vs. Phillips: the two models behind the math

Almost every training evaluation approach builds on one of two models.

The Kirkpatrick Model breaks evaluation into four levels: reaction, learning, behavior and results. Kirkpatrick Partners recommends starting with Level 4, the result you want, and working backward to design the program.

The Phillips ROI Methodology, from the ROI Institute, adds a fifth level that converts results to money and compares them to costs. It also adds a required step to isolate the effect of the program from everything else that changed at the same time.

You do not have to pick a side. Most employers use the Kirkpatrick levels for every program and add the Phillips ROI step only for the few programs big enough to justify it.

How to measure training ROI in six steps

These follow the ROI Institute’s six steps of cost-benefit analysis, in plain terms.

1. Identify the improvement in a business measure. Pick the measure before the program starts and record a baseline. Turnover on a team, safety incidents, error rates, customer complaints, days to full productivity. A measure chosen afterward is a story, not a result.
2. Isolate how much of the improvement came from training. Other things change too: a new system, a hiring freeze, a busy season. The ROI Institute lists several ways to separate them, including a control group, trend line analysis, forecasting, and estimates from participants and their managers. A control group is the strongest. Estimates are the most practical for small employers.
3. Convert the improvement to money. Use a standard value where one exists, such as the cost of a turnover, an error, or an hour of an employee’s time. Historical records, internal experts and published research all work as sources.
4. Total the fully loaded costs. Include needs assessment, design or purchase, delivery, participants’ time away from work, and the cost of the evaluation itself.
5. List the intangible benefits. Some results matter but are hard to price fairly, like teamwork, engagement or job satisfaction. Report them alongside the number rather than forcing a dollar value onto them.
6. Calculate the BCR and ROI. Compare the monetary benefits from step 3 to the costs from step 4.

A training ROI example

Here is how the math works for a supervisor program. The program fee uses Catapult’s current list price. Every other number is an illustration, so swap in your own.

The situation: A distribution company sends 10 new supervisors through the Fundamentals of Supervision Certificate Program, 3 days and 18 hours. In the 12 months before, their teams lost 9 frontline employees. In the 12 months after, they lost 6.

Two things to notice. First, the program paid for itself on turnover alone, after a deliberately cautious adjustment that credited the training with less than half the improvement. Second, the calculation leaves out everything else a better supervisor changes: fewer escalations, less overtime, fewer complaints to HR. Those belong in the intangible benefits, or in a second measure if you tracked it from the start.

If your managers would credit more of the drop to the program, the ROI climbs quickly. Resist the temptation. A conservative number that survives a CFO’s questions is worth more than a big one that does not.

Which programs deserve a full ROI study

Not every program needs one. The ROI Institute reserves the full analysis for programs that are very expensive, run for a long time, reach a lot of people, are comprehensive, or drive significant change in the organization.

For everything else, stop at Level 3. Confirm people are using the skill on the job and move on. A two-hour Excel class does not need a control group. A year-long leadership program for every manager in the company probably does.

Business measures to track by program type

For leadership programs specifically, bench readiness and promotion rates by cohort are covered in our guide on how to build a leadership development program.

Common mistakes that sink a training ROI number

• Picking the metric after the program. Without a baseline, there is nothing to compare against.
• Counting only the course fee. Participants’ time is often the biggest cost. Leaving it out inflates the ROI and invites pushback.
• Skipping isolation. Crediting training with every improvement is the fastest way to lose a finance team’s trust.
• Stopping at the smile sheet. Reaction surveys tell you whether people liked a program, not whether they use it.
• Waiting too long to check behavior. Kirkpatrick Partners warns against waiting 90 days to start measuring behavior. Check in early, so you can fix a program while it is still running.
• Measuring every program the same way. Save the full ROI study for the programs that justify it.

Courses for HR teams that need to prove the numbers

Measuring ROI is a skill, and so is presenting it to leadership. These live virtual courses cover both.

Where to start

Pick your most expensive program, or the one leadership questions most. Write down the business measure it should move and pull a baseline this week. Then follow the six steps above when the results come in. One credible ROI study does more for your training budget than a dozen satisfaction surveys.
