Are Big Five Tests Worth It? Honest Review of Cost and ROI

One major consideration before investing in a new tool for your business is the return on investment (ROI). It can be easier to determine the ROI on tangible assets like upgrading equipment or a new automated marketing system. 

But what about personality assessments? 

When used correctly, personality assessments can help you improve workplace culture, leading to lower turnover rates and higher retention. It can also be instrumental in the hiring process and pairing the right person in the right position.  

One option to consider is the WorkPlace Big Five Profileᵀᴹ. The Big Five (also known as the Five-Factor Model of personality) is backed by extensive research and offers a comprehensive understanding of employee motivations, work styles, and behaviors applicable across the employee lifecycle — but is it the right tool for your organization? 

Let’s dive into the cost, fit, and ROI of the Big Five assessment, so you can evaluate whether it’s the best choice for your company.

ROI of the Big Five test: Quantitative benefits

While it can be challenging to quantify some of the benefits of personality assessments, it is still possible to track KPIs – including metrics you are likely already watching – to show measurable advantages. 

Keep in mind that the specifics will vary depending on your company’s objectives, current benchmarks, and unique challenges.

Benefit #1: Enhance hiring accuracy 

Bad hires will cost you in the long run. In fact, the cost of recruiting and hiring can be 2-3 times their annual salary

The Big Five assessment gives you a clearer, more accurate understanding of someone’s personality, work styles, and more before you invest in hiring them. You can look beyond their resume and determine how well they’ll fit into the team, culture, and particular role.

To broadly calculate the impact of Big Five assessments on hiring optimization, you can use the following formula:

Formula to calculate the impact of Big Five assessments

If you hire 150 employees per year at an average salary of $120,000, let’s say 69 of those employees will be bad fits (considering an average 46% mis-hire rate). But implementing personality assessments can lower your mis-hire rate substantially. For example, even a modest but meaningful correlation of .20 between personality and job performance can lead to an estimated reduction in your mis-hire rate by roughly 25%. This brings the number of bad hires down to 52.

Even assuming a more conservative hiring cost estimate of 30% of annual salary, that comes out to:

Benefit #2: Increase productivity

In-depth personality assessments also help you place employees in teams, environments, and roles where they’ll thrive. Research from Gallup indicates that the average cost of disengagement is 18% of an employee’s annual salary — so this ROI factor is more significant than many organizations realize.

Let’s say you have 2,000 employees with an average salary of $120,000, and your company’s internal benchmarks align with global averages.

Now, let’s look at the numbers if a personality assessment raises your employee engagement rates to 75%:

In this situation, personality assessments lead to overall savings of $18,144,000

Benefit #3: Lower turnover rates

According to the Bureau of Labor Statistics, U.S. companies have an average turnover rate of 41%. This number likely includes many entry-level jobs, but even for C-level roles, estimates pin the average turnover rate at 5% with the stakes involved with these roles much higher in terms of potential impact and disruption to the business.

The average cost to replace an employee is 0.5 – 2x their annual salary, which means reducing turnover rates can have a significant impact on your bottom line. Using a median value of 23% (between 41% and 5%), that’s:
