The Business Case for Disability Inclusion: ROI Data and Metrics

Beyond Compliance: Disability Inclusion as a Business Strategy

For decades, disability employment was framed primarily as a compliance obligation or a charitable act. That framing is outdated. A growing body of research indicates that companies that actively include people with disabilities in their workforce outperform their peers on revenue, profitability and productivity.

This article presents the data that HR leaders and executives need to make the internal business case for disability inclusion.

The Accenture Research: "The Disability Inclusion Imperative"

In 2023, Accenture — in partnership with Disability:IN and the American Association of People with Disabilities (AAPD) — published The Disability Inclusion Imperative, a follow-up to its landmark 2018 report on disability inclusion at work in the United States. The research analysed around 346 US companies that took part in the Disability Equality Index (DEI) between 2015 and 2022.

Key Findings

Companies that led on key disability inclusion criteria saw, compared with other companies in the DEI:

• 1.6 times more revenue
• 2.6 times more net income
• 2 times more economic profit

Leaders were also more likely to outperform industry peers in productivity by 25 percent.

Why the Correlation

Several mechanisms help explain the link:

1. Innovation: Companies that design products and services to be accessible often discover innovations that benefit all users (the "curb cut effect")
2. Market access: Disability-inclusive companies are better positioned to serve the estimated 1.3 billion people with significant disabilities worldwide and their networks
3. Talent pool: By removing barriers, these companies access a larger talent pool and gain employees with different problem-solving perspectives
4. Culture: An inclusive culture can improve morale, engagement, and productivity across the entire workforce, not just among disabled employees

Retention: Keeping Valued Employees

Employee turnover is one of the largest hidden costs in any organisation, covering recruitment and onboarding, lost productivity during vacancies and ramp-up, loss of institutional knowledge, and lost training investment.

Workplace accommodations are a key retention tool. In the Job Accommodation Network's (JAN) employer survey:

• 56% of employers contacted JAN for guidance on retaining a current employee
• 85% of employers who made accommodations reported increased employee retention as a direct benefit
• 48% said accommodations eliminated the costs of training a new employee

Even a modest reduction in turnover translates into significant savings.

Attendance and Productivity

A common misconception is that accommodating employees with disabilities hurts attendance or output. Employers in JAN's survey reported the opposite:

• 52% reported increased employee productivity
• 47% reported increased employee attendance
• 29% reported increased overall company morale

Accommodation Costs: The Reality

Fear of accommodation costs is one of the primary barriers to disability hiring. The actual data is very different from many employers' expectations.

JAN Employer Survey Data

JAN surveyed employers who contacted it between 2019 and 2024. Of the 1,425 employers who shared cost information:

• 61% said the accommodation cost nothing (for example, modifying a work schedule or changing a company policy)
• 33% reported a one-time expense, with a median cost of $300 (for example, screen-reading software or an automatic door opener)
• 6% reported ongoing costs, with a median annual cost of $2,400 (for example, a sign language interpreter for meetings)

Employers who made accommodations reported that the benefits far outweighed the costs, including retained employees, higher productivity, avoided training costs and better attendance.

Innovation and the Curb Cut Effect

The "curb cut effect" refers to the phenomenon where features designed for people with disabilities end up benefiting a much larger population. The physical curb cut, designed for wheelchair users, is now used by parents with strollers, delivery workers with carts, travellers with luggage, and cyclists.

Business Examples

• Closed captioning: Developed for deaf and hard-of-hearing viewers, now widely used in gyms, airports, and for second-language learning
• Voice recognition technology: Now powers virtual assistants used by people everywhere
• Flexible work arrangements: Long used as accommodations for disabled employees, now standard practice that benefits many employees
• Universal design principles: Designing for the widest range of users from the outset expands the potential customer base

The Disability Market

People with disabilities represent an enormous and underserved consumer market:

• 1.3 billion people worldwide — 16% of the global population — experience significant disability (WHO)
• People with disabilities aged 25–64 in the US, UK, EU and Canada alone control over $2.6 trillion in disposable income (Return on Disability Group, 2024)
• In the US alone, people with disabilities control $1.3 trillion in annual disposable income
• Including friends and family, the global disability market is valued at $18.3 trillion (Return on Disability Group, 2024)

ESG, DEI, and Investor Expectations

Disability inclusion increasingly features in how companies report on their workforce and sustainability:

• The Disability Equality Index is a leading benchmarking tool that scores businesses on disability inclusion policies and practices; 485 companies used it to benchmark their efforts in the year before Accenture's 2023 report
• Self-identification is low: The 2023 DEI report found only 4.6 percent of employees self-identify their disability status with employers, and Accenture research found 76 percent of employees with disabilities do not fully disclose at work — so building trust and data is itself a business priority
• US SEC filings now require a human capital overview, and voluntary mentions of disability inclusion in them are notable

Companies that build disability inclusion programmes now are better positioned as expectations around workforce disclosure grow.

Building Your Internal Business Case

Data You Can Gather Internally

1. Current turnover costs: Calculate your cost-per-hire and annual turnover rate
2. Accommodation spend: Track actual accommodation costs versus budget assumptions
3. Applicant demographics: What percentage of your applicant pool discloses a disability?
4. Retention comparison: If you already employ people with disabilities, compare their retention rates

Framing the Proposal

Present disability inclusion as a business strategy with measurable ROI, not as a compliance exercise or charitable initiative:

Setting Measurable Goals

• Number of disability-inclusive job postings per quarter
• Percentage of new hires who disclose a disability
• Average time-to-accommodation for new hires
• Retention rate comparison at six months, one year and two years
• Disability Equality Index score improvement year over year
• Employee engagement scores among disabled employees versus overall workforce

Conclusion

The business case for disability inclusion is not theoretical. It is supported by research from Accenture, JAN and others. Companies that lead on disability inclusion outperform their peers on revenue, profitability and productivity. The cost of accommodations is usually low, the benefits are substantial, and expectations around workforce disclosure are growing.

The question is no longer whether disability inclusion is good for business. The question is how quickly your organisation can implement it.
