The soccer star got through nearly £5million, according to his company finances, reports the News of the World.
In the last financial year Rooney's company Stoneygate 48 ended up £603,241 in the black.
But this year, the figure has plunged to £1.1million in the red. As his estimated £3million a year from sponsorship deals with Nike and Coca-Cola go through the firm, that means he spent around £4.7million.
Chief among the Manchester United and England star's expenses was his wedding to childhood sweetheart Coleen McLoughlin.
The pair spent an estimated £100,000 per head at the bash in Italy last month.
The pair have a £4.5million home in Prestbury, Cheshire, as well as a fleet of cars including a Lamborghini, an Aston Martin and a Bentley.
But Rooney still has his £130,000-a-week salary going straight into his personal bank account.
Coleen's earnings are also impressive. She has her own perfume range, book deals and magazine columns.
