Design System ROI Calculator

Prerequisites

• Access to team headcount and approximate salaries or hourly rates
• Basic understanding of which teams use the design system
• Willingness to present conservative estimates (overpromising destroys trust)

When NOT to use this

• If your design system is less than 6 months old — you don't have enough data for credible efficiency claims
• If you're the only person using it — individual productivity gains don't justify system investment
• If leadership has already approved budget — save the ROI theater for renewal discussions
• If your organization doesn't make decisions based on financial data — some cultures need different proof

Consider instead

• Leadership wants qualitative proof, not numbers: Use adoption metrics and user testimonials from the Adoption Dashboard
• You need to justify ongoing investment, not initial: Use the Progress Dashboard Spec to show sustained value
• Finance wants a formal business case document: Use the Executive Pitch Deck as the presentation layer for your ROI numbers
