Training ROI
Definition
Training ROI is the net financial benefit of a training program divided by its total cost, expressed as a percentage. It is calculated as (monetary benefits minus costs) divided by costs, times 100. It is the fifth level in the Phillips ROI model and is used to justify, compare or cut training investments.
Also called: ROI of training, return on investment of training, learning ROI, Phillips ROI
Formula
Training ROI (%) = (Monetary benefits − Total program costs) ÷ Total program costs × 100
- Monetary benefits
- The dollar value of improvements caused by the training over a set period, such as lower turnover, fewer errors, faster ramp-up or higher sales, after isolating the training's share.
- Total program costs
- Fully loaded costs: design and development, vendor or license fees, trainer time, learner wages while in training, travel, facilities and evaluation.
Worked example
A new nesting program costs $75,000 a year. It produces $180,000 in benefits, so ROI = ($180,000 − $75,000) ÷ $75,000 × 100 = 140%. The benefit-cost ratio is $180,000 ÷ $75,000 = 2.4.
Where the Phillips ROI model fits
Most training evaluation starts with the Kirkpatrick model and its four levels: reaction, learning, behavior and results. Jack Phillips added a fifth level, ROI, which converts Level 4 results into money and compares them with fully loaded costs. His ROI Methodology also stresses two steps that Kirkpatrick leaves open: isolating the effect of training from everything else that changed, and listing intangible benefits you choose not to convert to dollars.
You'll also see the benefit-cost ratio (BCR), which is benefits divided by costs. A BCR of 2.4 and an ROI of 140% describe the same result. Finance teams often prefer ROI because it lines up with how they compare other investments.
Worked example: contact-center nesting program
A 300-seat customer service center runs 12 new-hire classes a year of 25 people each. Before the change, 30% of each class left before day 90, and new agents took about 10 weeks to reach target handle time and quality.
The L&D team adds a structured two-week nesting phase with dedicated coaches. Annual costs: $40,000 to design (spread over the first year), $35,000 in coach time and materials. Total: $75,000.
After a year, 90-day training attrition falls to 20%. That's 2.5 more agents retained per class, 30 a year. At roughly $4,000 to recruit and train each replacement, that saves $120,000. Speed to proficiency also improves by about two weeks, worth an estimated $60,000 in reduced overtime and lower transfer rates.
Gross benefit: $180,000. ROI: 140%.
Now the honest step. Pay also rose 50 cents an hour at the same time, which may explain part of the attrition drop. Comparing with a sister site that got the raise but not the program suggests training accounts for about 60% of the improvement. Adjusted benefit: $108,000. Adjusted ROI: 44%. Still a good investment, and a number that survives scrutiny from finance.
How to isolate the effect of training
This is where most ROI claims fall apart. Options, from strongest to weakest:
- Control group. Train one site, team or class and compare with a similar group that wasn't trained over the same period.
- Trend line. Project the metric forward from its pre-training trend and compare actual results against the projection.
- Staggered rollout. Train groups in waves; each untrained group acts as a temporary control.
- Participant and manager estimates. Ask how much of the change they attribute to training and how confident they are, then discount by that confidence. Phillips describes this method; it's weaker but better than claiming 100%.
Volume operations are well suited to the first three because they run many similar classes. A company training 20 people a year will rely more on estimates.
Which programs deserve a full ROI study
A full ROI calculation takes real effort, so reserve it for programs that are expensive, strategic, high-visibility or under threat of being cut. Good candidates: new-hire programs for high-volume roles, sales training, leadership programs and large systems rollouts. Phillips suggests only a small share of programs need a Level 5 study; for the rest, solid Level 3 and 4 data is enough.
For onboarding programs, the cleanest monetary benefits usually come from early turnover, time to productivity, quality errors and overtime. For leadership programs, from team turnover and engagement scores, which are harder to convert and should often stay as intangibles.
Common mistakes
- Counting only vendor fees. Learner wages during training are often the largest cost for hourly populations. Leave them out and ROI looks inflated.
- Claiming 100% of the improvement. Something else always changed: pay, staffing, a new manager, a seasonal dip in volume.
- Choosing metrics after the fact. Agree with the business owner which metric the program should move before it launches.
- Too short a window. Turnover benefits take 90 days or more to show; leadership benefits can take a year.
- Converting everything to dollars. Some benefits, like better morale, are real but hard to price. Report them as intangibles rather than inventing a number.
Frequently asked questions
How do you calculate the ROI of training?
Subtract total program costs from the monetary benefits the training produced, divide by total costs and multiply by 100. Include learner wages in costs and isolate the share of improvement caused by training.
What is the Phillips ROI model?
Jack Phillips's ROI Methodology adds a fifth level, return on investment, to the Kirkpatrick model. It converts business results into money, isolates the effects of training and compares benefits with fully loaded costs.
What is a good ROI for training?
Any positive ROI means benefits exceeded costs. Many organizations set a hurdle similar to other investments, often somewhere around 20 to 25 percent. Very high reported figures usually mean the training's effect was not isolated.
What is the difference between ROI and benefit-cost ratio?
BCR is benefits divided by costs. ROI is net benefits divided by costs, as a percentage. A BCR of 2.0 equals an ROI of 100 percent.
How long after training should you measure ROI?
Long enough for behavior and results to show. For onboarding and turnover-related programs, 90 days to a year; for sales training, often one or two sales cycles.
