What is Discount Matrix?
Published May 7, 2026
The E-Rate discount matrix is the FCC schedule that determines how much of an applicant's eligible costs USAC will reimburse — between 20% and 90%. The percentage is based on the applicant's National School Lunch Program (NSLP) percentage and whether the applicant is classified as urban or rural.
How is the discount calculated?
The discount comes from a published matrix that pairs NSLP-eligibility bands (1–19%, 20–34%, 35–49%, 50–74%, 75%+) with urban/rural status. A 75%+ NSLP rural applicant gets the maximum 90% discount; a 1–19% NSLP urban applicant gets the minimum 20%.
Libraries take the discount of the school district they reside in, with adjustments for community-need indicators. Consortia use a weighted-average calculation across member entities.
Where does the NSLP percentage come from?
Historically, applicants reported their NSLP percentage directly on Form 471. Many districts in Community Eligibility Provision (CEP) status now use a CEP-derived rate. Some states have moved to alternate measures of economic need.
USAC publishes each applicant's discount rate alongside the public commitment data, so the discount applied to any historical filing is part of the public record.
