The charity receives a grant from the Ministry of Defence (MOD) to deliver its activities in support of the cadets and adult volunteers of the Army Cadet Force (ACF). Other income comes from affiliation fees from ACF Counties, Battalions and Sectors, membership fees from individual members, a sports grant from the Army Sports Control Board, a grant from the Cadet Vocational Qualifications Organisation (CVQO) and donations from sponsors of the Outreach projects.
ACF Outreach projects are funded separately from all other ACFA supported activities. The money is obtained from charities and corporations which donate towards the Outreach running costs. The scheme costs around £350,000 a year to run and donations have consistently matched this expenditure. The money is accounted for separately from the main ACFA account.
In accordance to Charity Commission rules that direct a working reserve must be retained, surplus income has been placed into the reserve. The ACFA Trustees have directed that this reserve must match 12 months' working costs. The fund is placed on the markets with an Investment Manager, currently Rensburg Sheppards. The Outreach fund has a similar reserve also placed with Rensburg Sheppards.
