(BOSTON, MA) – Despite the essential role of language services in global operations, many organizations still treat translation and localization as sunk costs rather than strategic investments. In its 2025 report, A Practical Guide to Building the ROI Case for Localization, market research firm CSA Research presents a comprehensive methodology to help organizations quantify and demonstrate the revenue impact of language services.

CSA Research worked with enterprise localization leaders and relied on its suite of Global Business Analytics tools to build a framework that moves beyond vague assumptions. The report details a practical, step-by-step approach that organizations can use to assess the value created by their investments in translation, localization, and interpreting services.

“The problem isn’t that localization doesn’t produce ROI—it’s that many teams don’t have access to the right data or methodology to prove it,” explains lead analysts Arle Lommel and Alison Toon. “This report enables language teams to speak the language of the C-suite—revenue, margin, and market opportunity.”

Key findings show that effective ROI measurement requires mapping the cost of both source and localized content to the revenue it enables. The report urges organizations to rethink how they measure success, using not just cost savings but metrics like market access, customer experience, and engagement.

For example, CSA Research shows that translating only a fraction of customer-facing content may limit revenue from international markets. Companies can use tools such as the Global Revenue Forecaster™ and Global Customer Experience Calculator™ to simulate how localization improvements could unlock tens of millions in additional revenue.

The report includes:

• A step-by-step methodology for calculating localization ROI
• Examples and illustrations using real-world scenarios
• Guidance on estimating source and target content costs
• Instructions for presenting ROI findings to executives
• Recommendations for identifying new market and language opportunities
• Insights into maximizing effectiveness in existing locales
• Guidance tailored for both enterprises and LSPs

“ROI should not be an afterthought. It must be embedded into how companies evaluate and fund localization programs,” say the authors. “Whether you’re defending your current budget or pitching an expansion into a new market, this guide helps you prove the value of your work.”

The guide emphasizes that language services are not a luxury but a growth enabler. When presented strategically, ROI metrics shift localization from a discretionary expense to a competitive advantage.

A Practical Guide to Building the ROI Case for Localization is the latest in a series of CSA Research reports focused on maximizing globalization and international content investment.
