Help for Heroes has announced it has raised £100m since it was set up in October 2007, half of it in the past year.
It means the charity, which supports injured members of the armed forces, has raised an average of £74,130 a day since it began.
It has attracted high-profile support from people such as the Princes William and Harry, the singer James Blunt and Simon Cowell, the music mogul and judge on the TV talent show The X Factor.
In 2010, finalists from The X Factor released the single Hero for the charity. It reached number one and became the fastest-selling charity single of the decade.
A spokeswoman for the charity said that, on average, 500 fundraising events were held every week on behalf of the charity.
Bryn Parry, founder and chief executive of Help for Heroes, said in a statement: "When we launched on 1 October 2007, it was a very daunting prospect indeed. Now, less than four years later, we are staggered, humbled and very proud indeed to be involved in a charity that has become a national phenomenon."
