Abstract: Aspects of the present disclosure relate to data-backed compensation estimation based on disparate electronic data sources. User data, Client data, External data, and Legal standard data are used to identify “Like Me” entities and to determine degrees of reasonableness of compensation for “Like Me” entities. User data includes various information about the user and the company from which the user is being compensated. Client data includes data about other entities which may be like the user. External data includes data which may factor in adjusting the value or reasonableness of a compensation amount. Legal standards may determine that a compensation amount is or is not reasonable for an entity. Estimates for reasonable compensation may be based on the “Like Me” entities in consideration of external factors and legal standards relevant to reasonableness of the compensation for that entity.
