Digital Accessibility ROI Calculator: Cost of Non-Compliance vs Implementation

TestParty

March 12, 2025

Accessibility investment decisions often stall when stakeholders frame compliance as pure cost. The calculation changes dramatically when organizations quantify both sides of the equation: the cost of implementation versus the cost of non-compliance.

This guide provides a framework for calculating accessibility ROI—accounting for legal risk, market opportunity, operational efficiency, and brand value. The goal isn't to reduce accessibility to pure financial terms, but to provide business leaders with data that supports informed investment decisions.

The Two Sides of Accessibility Economics

Accessibility ROI calculations must consider both implementation costs and non-compliance costs.

Implementation Costs (Investment)

Direct Costs:

Accessibility assessment and auditing
Remediation development
Monitoring platform subscriptions
Training and process development
Documentation and reporting

Indirect Costs:

Developer time allocation
Project management overhead
Release cycle impact
Ongoing maintenance

Non-Compliance Costs (Risk)

Legal Costs:

Lawsuit settlements
Attorney fees (defense and plaintiff)
Court-ordered remediation
Ongoing monitoring mandates

Business Costs:

Lost revenue from excluded customers
Customer acquisition inefficiency
Brand reputation damage
Competitive disadvantage

Operational Costs:

Emergency remediation premium
Rush timeline penalties
Expedited vendor engagement
Staff time for legal response

Legal Risk Calculation

Legal exposure represents the most quantifiable non-compliance cost.

Lawsuit Probability

While no formula predicts individual lawsuit likelihood, risk factors include:

Industry: E-commerce, healthcare, hospitality, and financial services face elevated litigation rates. See our ADA Lawsuit Statistics for industry breakdown.

Organization Size: Higher visibility increases targeting probability. However, small businesses aren't immune—plaintiffs target organizations across all sizes.

Website Traffic: Higher traffic means more potential plaintiffs encountering barriers.

Current Accessibility State: Sites with severe, detectable barriers are easier targets for plaintiff attorneys using automated scanning.

Cost Per Lawsuit

Settlement Ranges:

| Organization Size | Settlement Range   | Attorney Fees (Defense) |
|-------------------|--------------------|-------------------------|
| Small Business    | $10,000-$50,000    | $10,000-$30,000         |
| Mid-Size          | $25,000-$100,000   | $20,000-$75,000         |
| Enterprise        | $100,000-$500,000+ | $50,000-$200,000+       |

Additional Costs:

Plaintiff attorney fees (often equal to or exceeding settlement)
Injunctive relief compliance (forced remediation)
Monitoring and reporting requirements
Potential follow-on litigation

Expected Legal Cost Calculation:

Estimated lawsuit probability × Average settlement cost = Expected annual legal cost

Example:
10% annual lawsuit probability × $50,000 average cost = $5,000 expected annual cost

This expected value calculation helps compare legal risk against compliance investment.

Market Opportunity Calculation

Accessibility expands addressable market beyond disability statistics alone.

Direct Market Impact

Disability Population: The CDC reports 26% of American adults have a disability. The WHO estimates 16% globally.

Market Size Calculation:

Annual revenue × Disability percentage × Barrier impact rate = Lost revenue opportunity

Example:
$5,000,000 revenue × 26% disability rate × 15% experiencing barriers = $195,000 annual opportunity

The "barrier impact rate" acknowledges that not all users with disabilities encounter barriers on every site visit. Conservative estimates range from 10-25% depending on site accessibility state.

Indirect Market Impact

Aging Population: As populations age, accessibility needs increase. Users who didn't need accessibility features at 40 may require them at 60. Building accessible now captures future customer retention.

Situational Accessibility: Users without permanent disabilities benefit from accessibility in situational contexts:

Bright sunlight reducing screen visibility
Noisy environments limiting audio
One-handed device use while multitasking
Slow internet connections requiring efficient code

Friends and Family: Purchasing decisions involve networks. Inaccessible experiences affecting one family member influence entire household brand preferences.

B2B Market Requirements

Enterprise Procurement: Large organizations increasingly require vendor accessibility compliance. Healthcare, government, education, and financial services sectors mandate accessibility in procurement.

Revenue at Risk:

B2B contract pipeline × Contracts requiring accessibility × Win rate impact = B2B revenue impact

Example:
$2,000,000 pipeline × 30% requiring accessibility × 25% win rate reduction = $150,000 at risk

Operational Efficiency Calculation

Accessible code often performs better, reducing operational costs.

Performance Correlation

Clean Code Benefits: Accessibility remediation frequently involves cleaning up HTML structure, reducing JavaScript complexity, and improving semantic markup. These changes correlate with:

Faster page load times
Better Core Web Vitals scores
Improved search engine crawling
Reduced maintenance complexity

SEO Impact: Accessibility and SEO share significant technical overlap. Accessible sites often rank better due to improved structure, alt text, and semantic HTML. Quantifying SEO value:

Monthly organic traffic × Conversion rate × Average order value × SEO improvement estimate = SEO value

Example:
50,000 visits × 2.5% conversion × $75 AOV × 10% traffic improvement = $9,375/month additional revenue

Reduced Support Costs

Accessibility-Related Support: Users encountering barriers contact support, increasing costs:

Call center time spent on navigation assistance
Complaints requiring escalation
Negative reviews requiring response
Social media reputation management

Development Efficiency

Prevention vs. Remediation: Catching accessibility issues during development costs far less than fixing production issues:

| Discovery Stage      | Cost Multiplier |
|----------------------|-----------------|
| Development (IDE)    | 1x              |
| Pull Request (CI/CD) | 2-5x            |
| Testing              | 5-10x           |
| Production           | 10-25x          |
| Post-Lawsuit         | 25-50x+         |

Investment in development workflow integration (like TestParty's Bouncer and PreGame) reduces long-term remediation costs.

Brand Value Calculation

Brand impact is harder to quantify but represents real business value.

Reputation Economics

Positive Positioning: Accessibility leadership creates positive brand associations:

Social responsibility perception
Quality and attention to detail signals
Inclusion as company value

Negative Exposure: Accessibility failures create negative associations:

Lawsuit publicity
Social media criticism
Advocacy organization attention
Competitive exploitation

Customer Loyalty Impact

Disability Community Influence: Disability communities actively share information about accessible businesses. Positive experiences generate referrals; negative experiences generate warnings.

Net Promoter Score (NPS) Impact: Accessibility improvements often correlate with NPS improvements as overall user experience improves.

Competitive Differentiation

In markets where competitors have similar products and pricing, accessibility can provide differentiation. Given that most websites have accessibility issues (according to WebAIM's annual analysis), accessibility excellence stands out.

ROI Calculation Framework

Step 1: Quantify Non-Compliance Costs

Legal Risk:

Lawsuit probability × (Settlement + Defense fees + Plaintiff fees + Remediation) = Legal risk cost
10% × ($50,000 + $25,000 + $30,000 + $40,000) = $14,500/year expected

Lost Revenue:

Revenue × Disability rate × Barrier impact × Conversion loss = Lost revenue
$5,000,000 × 26% × 15% × 50% = $97,500/year

B2B Impact:

Pipeline × Accessibility-required contracts × Win rate impact = B2B loss
$2,000,000 × 30% × 25% = $150,000/year

Total Non-Compliance Cost: $14,500 + $97,500 + $150,000 = $262,000/year

Step 2: Quantify Implementation Costs

Initial Assessment: $5,000 Remediation Sprint: $25,000 Annual Monitoring: $6,000/year Ongoing Development: $12,000/year Training: $3,000/year

Year 1 Total: $51,000 Ongoing Annual: $21,000/year

Step 3: Calculate ROI

Year 1 ROI:

(Non-compliance cost avoided - Implementation cost) / Implementation cost × 100

($262,000 - $51,000) / $51,000 × 100 = 414% ROI

Ongoing ROI:

($262,000 - $21,000) / $21,000 × 100 = 1,148% ROI

Step 4: Calculate Payback Period

Payback Period:

Implementation cost / Monthly non-compliance cost = Months to payback

$51,000 / ($262,000 / 12) = 2.3 months

Q&A: Accessibility ROI

Q: These numbers seem theoretical—how confident can we be in ROI projections?

A: Conservative assumptions make projections reliable minimums. Legal costs are well-documented from actual settlements. Market statistics come from reputable sources (CDC, WHO). The framework intentionally uses conservative estimates—actual ROI often exceeds projections. Organizations can adjust inputs based on their specific circumstances.

Q: Our legal team says we've never been sued for accessibility—why assume we will be?

A: Past performance doesn't predict future results. Accessibility lawsuits are increasing annually. Having avoided litigation so far may reflect luck rather than low risk. Additionally, legal risk is only one component—market opportunity and operational efficiency provide ROI even without lawsuit probability.

Q: How do we account for accessibility improvements we've already made?

A: Adjust barrier impact rate and legal probability based on current state. Sites with partial compliance have lower non-compliance costs than sites with no accessibility attention. The framework scales to any starting point.

Q: What if our organization doesn't sell directly to consumers?

A: B2B organizations still face: employee-facing accessibility requirements, customer-facing portal accessibility, procurement requirements from accessibility-conscious buyers, and brand reputation in professional markets. Adjust market calculations to reflect B2B contexts.
