Companies in the United States spend approximately $800 billion annually on sales force compensation. The prevailing logic suggests that to get the best results from salespeople, a business must offer significant financial rewards, such as commissions, bonuses, and contests. This approach relies on the assumption that external incentives are the primary drivers of human behavior in a professional setting.
However, a team of researchers investigated whether this financial focus is actually the most effective way to drive performance. Led by Valerie Good of Grand Valley State University, the team published a study in the Journal of the Academy of Marketing Science in 2022 that challenges long-held assumptions about what makes a salesperson successful. Their investigation synthesized decades of data to compare the power of internal drive against the allure of external rewards. The central finding indicates that while money matters, a salesperson’s internal desire to succeed is a stronger predictor of performance.
Defining the Motivation Gap
Sales managers constantly face the challenge of keeping their teams productive. Salespeople work with a high degree of autonomy, meaning they choose how much effort to exert and which strategies to employ on any given day. They also face frequent rejection and external disruptions, such as economic downturns or competitive shifts. Good and her colleagues—Douglas E. Hughes, Ahmet H. Kirca, and Sean McGrath—sought to understand how different types of motivation sustain a salesperson through these challenges.
To explore this, the researchers utilized Self-Determination Theory (SDT). This framework separates motivation into two distinct categories. The first is intrinsic motivation. This occurs when a salesperson acts because they find the work itself interesting, enjoyable, or satisfying. They feel a sense of autonomy and competence in their role.
The second category is extrinsic motivation. This is often described as “controlled” motivation. It occurs when a salesperson feels pressured to think or behave in a certain way to obtain a separate outcome, such as a financial bonus or public recognition. The researchers aimed to determine which of these two motivational pathways has a stronger link to actual sales outcomes.
Constructing the Meta-Analysis
The research team chose a meta-analysis as their method of investigation. This statistical technique allows researchers to combine the results of many prior studies to identify patterns that a single experiment might miss. The team began by searching electronic databases for academic articles, dissertations, and working papers published between 1985 and the present.
They used specific keywords related to sales, performance, and various forms of motivation, such as “incentives,” “autonomy,” and “compensation.” To ensure the data was relevant to the real business environment, they excluded studies that focused on students in laboratory settings. They strictly limited their dataset to studies involving actual salespeople and individual performance metrics.
Following a rigorous filtering process, the researchers identified 127 unique studies containing 1,242 separate effect sizes. This created a massive sample pool representing more than 77,000 salespeople. The team then coded these studies to extract correlations between the different types of motivation and performance. They also categorized the data by variables such as age, gender, sales experience, and industry type.
Analyzing the Performance Data
The primary analysis compared the strength of the relationship between intrinsic motivation and performance against the relationship between extrinsic motivation and performance. The data revealed that both types of motivation are positively linked to better sales numbers. However, the link between intrinsic motivation and performance was significantly stronger than the link for extrinsic motivation.
The researchers broke this down by how performance was measured. When performance was rated by the salespeople themselves, intrinsic motivation showed a very strong correlation. When performance was measured objectively—such as by total revenue or units sold—intrinsic motivation still showed a stronger association than external rewards.
The Role of Age and Experience
The study also looked at how these dynamics shift as salespeople age. The data showed that intrinsic motivation remains the dominant factor for both younger and older workers. However, the gap between the two types of motivation widens with age. Older salespeople showed a much stronger connection between intrinsic drive and performance than their younger counterparts.
Conversely, the analysis showed that extrinsic motivation had a stronger link to performance for younger salespeople than it did for older ones. This suggests that while younger workers may respond reasonably well to financial incentives, this responsiveness tends to diminish as they mature.
A similar pattern appeared regarding job tenure. For salespeople with more experience in sales and longer tenure at their specific jobs, intrinsic motivation was a more powerful predictor of success. For those new to the field, external incentives played a larger role than they did for veterans, but internal drive remained the primary factor.
Industry and Gender Differences
The researchers examined whether the type of selling environment influenced these results. They compared Business-to-Business (B2B) sales against Business-to-Consumer (B2C) sales. In the B2B context, which often involves complex decision-making and long-term relationship building, intrinsic motivation was far superior to extrinsic rewards in predicting performance.
In B2C settings, where transactions may be faster and more transactional, the gap narrowed. Extrinsic motivation proved to be more effective in B2C settings than in B2B settings. However, even in consumer sales, intrinsic motivation performed as well as or better than external incentives.
The study also analyzed gender differences. For samples with a higher percentage of female salespeople, the relationship between intrinsic motivation and performance was significantly stronger than the relationship involving extrinsic rewards. In male-dominated samples, the two types of motivation were closer in impact, though intrinsic drive still held a slight advantage.
Surprising Geographic Findings
One of the investigation’s unexpected revelations involved the location of the salespeople. The researchers compared samples from within the United States to international samples. Conventional wisdom often characterizes the U.S. workforce as highly coin-operated and focused on financial gain.
The data contradicted this stereotype. The correlation between intrinsic motivation and performance was actually stronger for U.S.-based salespeople than for those outside the country. Conversely, international samples showed a stronger link between extrinsic motivation and performance than the U.S. samples did.
Implications for Business Leaders
These findings offer specific guidance for sales managers and executives. The results suggest that while financial compensation is necessary, it acts largely as a baseline requirement rather than a tool for continuous growth. Once a salesperson has a fair and stable income, additional external rewards yield diminishing returns compared to internal drivers.
Managers looking to boost numbers might achieve better results by fostering an environment that satisfies innate psychological needs. This includes “autonomy,” which allows salespeople to decide how they approach their work, and “competence,” which involves helping them feel capable and effective.
Fostering Connection and Competence
The study points toward leadership strategies that emphasize coaching and skill development over contests and cash bonuses. Since intrinsic motivation is linked to feelings of self-efficacy, managers can drive performance by providing positive feedback that highlights what a salesperson is doing well.
Additionally, the research highlights the need for “relatedness” or connection. Salespeople often perform better when they feel valued by their peers and their organization. Creating a culture of belonging could be a more cost-effective way to increase revenue than increasing commission rates.
Tailoring the Approach
Finally, the researchers note that a uniform approach to motivation is inefficient. The data indicates that a younger sales force in a B2C environment might still benefit significantly from contests and financial targets. In contrast, a veteran sales team in a complex B2B industry would likely see little benefit from such schemes and would respond better to increased autonomy and opportunities for professional mastery.
By understanding that the most powerful engine for sales performance is internal, businesses can rethink their investment strategies. Shifting focus from “controlling” behavior through money to “supporting” behavior through culture and autonomy may provide a competitive advantage.
