The Society of Depreciation Professionals (Society or SDP) provides membership, training and professional certification opportunities to individuals seeking an in-depth understanding of capital recovery through the art of depreciation analysis. The Society was formed in 1987, in response to a need for objective and accurate estimates of equipment life, salvage and cost of removal for capital intensive industries.
The SDP recognizes the professional field of depreciation analysis and promotes the development of practitioners in the field. The Society further serves as a forum for the collection, exchange, and publication of information concerning depreciation, and sanctions standards of conduct through its code of ethics.


The Society holds its Annual Conference and Training in locations throughout the United States each fall. The Conference provides a unique opportunity for depreciation professionals to network and learn from leaders in the field as they discuss current trends. Our renowned training ranges from Depreciation Fundamentals to Life and Salvage Analysis courses with real-world applications to valuable instruction in Preparing and Supporting a Depreciation Study.

Depreciation Texts Available

The SDP is pleased to announce the opportunity to acquire three highly regarded depreciation textbooks: Depreciation Systems, Bulletin 125, and Bulletin 155. These publications have been out of circulation in recent years, but SDP has obtained special publication rights. These books are provided as a gift with a donation to the SDP Education Fund.
