The benefits of SENTRI and Global Entry may seem similar to each other, but there are certain differences that can contribute to the higher fees that SENTRI requires from its applicants. Global Entry is limited to people who are in the United States and to the residents of the United States of America.
It may also be open to a limited number of countries, while SENTRI will be available to almost everyone as long as the country from where the person is from is aligned with the United States. Global Entry would also require the applicants to have a passport, while SENTRI will not require this. The fact that SENTRI is more accessible to people makes this more expensive.

SENTRI is a U.S. Customs and Border Protection (CBP) program that allows expedited clearance for pre-approved when they arrived in the United States. To apply for SENTRI, you have to pay a $122.25 USD non-refundable fee. Why it is more expensive than the Global Entry is unknown. The Global Entry costs a $100 fee that is non-refundable.

The fee includes a $25 fee for the application, $14.50 for fingerprint fee, and $82.75 system cost fee.
