Forsyth School maintains a robust Financial Aid Program for qualifying families. Need-based awards are determined by the School's Financial Aid Committee. For 2020/21, the average financial aid award was nearly $7,500; approximately 24% of students received need-based grants.

Families are required to apply for financial aid online through FACTS Grant & Aid. All information is kept strictly confidential. The financial situation of all families varies, so the Financial Aid Committee considers each application individually. In general, families with a combined annual income of less than $150,000 often receive some tuition assistance. Regarding the matter of divorce or separation, the Financial Aid Committee considers the assets of both parents before making any award.

Families who qualify for and receive financial aid receive 50% off Extended Day (Before Care and After Care) fees, plus a percentage reduction on fees for League Sports.

Forsyth's online application for financial aid opens annually on November 1.
