Membership dues for Sigma are comprised of international and chapter fees. As of 1 July 2017, the international dues are:

            High Income     US $73.00

            Middle Income  US $29.20

            Low Income      US $14.60

*These fee categories are based on a country’s GNI per capita as defined by World Bank Basic Indicators table.

Chapter fees are set by individual chapters. A listing of chapter fees can be found within the Chapter Directory. Members that need assistance with the cost of dues can submit an Edith Anderson Membership Subsidy request form.  

During the 2003 Biennial Convention, the House of Delegates approved a change to Sigma’s bylaws that grants the International Board of Directors fiscal authority over fees. This means that in addition to other fiscal responsibilities, the board has the ability to make incremental restricted dues adjustments, based on the rate of inflation. This enables the board to fully manage the Sigma's resources—allowing them to respond to economic conditions, inflation and the increased costs of doing business—all while strengthening member services.

When adjustments are made to the international or chapter portion of the membership dues, Sigma international bylaws state that the increase in dues cannot exceed the cumulative increase in the Consumer Price Index (CPI) since the last increase.
