ESI (Electronic Stored Information) Calculator

Forecasting Your Document Review Budget

The first step is calculating the amount of electronic stored information (ESI) you have, and subsequently determining document and page equivalencies. This allows you to estimate how many contract attorneys a project will require within a given timeline.

Below are some general conversion guidelines and definitions as a guide to estimating your document review project scope and cost. However, it is best to contact us directly since Hudson Legal can provide you with the best advice on options to meet your needs.
