Tearfund says it can now give 1,066,530 people food after a swell in support at the annual event, attended by more than 22,000 Christians.
The money will be used in disaster hit areas, according to Steve Adams, Tearfund's Head of Global Brand and Communications.
He said: "Disasters reduce people's ability to live safely and have an impact on health and a family's ability to earn a living.
"We are grateful for the generous response of festival-goers to the campaign, which will help communities affected by the complex consequences of disaster."
Most of the meals will be provided in Africa, in countries like Chad which is in the grip of a drought and impending famine.
Ethiopia, which has been affected by drought, two failed harvests and 10.2 million people in need of emergency food assistance, will also be helped.
