The cost of the London Olympics and Paralympics will be £377m less than expected, according to the government.
The combined budget for the two events was £9.29bn, but the projected cost is £8.92bn.
Savings came from a drop in security, transport and construction expenses.
Sports minister Hugh Robertson said: "London 2012 was a tremendous success and it is a significant achievement to deliver this large and complex programme on time and under budget."
