Cost Benefit and ROI Calculator

What does your library contribute to the bottom line?

How much benefit does your institution, your user, receive for every dollar spent by the library? What's the annual return your institution realizes on what you spend on your collection? Cost/Benefit Analysis and Return on Investment are measures often used by financial managers to gauge the efficiency and effectiveness of their budget policies.

Fill in the fields in the table and see what you contribute. The Cost/Benefit ratio and the Return on Investment percentage will display at the bottom of the table.
