ROI of Digital Accessibility: Numbers, Facts, and Hard Calculations

Digital accessibility is often misunderstood as a cost factor. Yet concrete numbers and case studies from practice show the opposite: accessibility is one of the most profitable investments companies can make. With an average ROI of over 3,700% and measurable revenue increases of up to 38%, accessibility should be at the top of the priority list^[1][2][3].

The Billion-Euro Target Audience You're Overlooking

Before we dive into the numbers, a crucial fact: approximately 7.8 million people in Germany live with a severe disability^[4]. Across Europe, there are 87 million people with a disability, whose annual purchasing power is estimated at 800 billion euros^[5][6]. These numbers don't even account for temporary impairments from injuries, age-related changes, or situational barriers like poor lighting conditions.

Microsoft introduced the concept of "situational disabilities" in a groundbreaking study: a user with a broken arm has similar needs to someone with permanent motor impairments^[1]. Adding all these factors, up to 30% of the population directly benefits from accessible digital offerings^[3][7].
