The Queen last year reduced her cost to the taxpayer by £1.8m, despite a substantial rise in the amount spent on Royal travel.
While Buckingham Palace insisted a £2.1m rise in the cost of moving members of the House of Windsor around was largely due to changes in leasing arrangements of the Royal helicopter, even with that taken into account, the cost of Royal travel rose £600,000 - or 11% - to £6m.
The most expensive journey was the state visit in November to the United Arab Emirates and the Sultanate of Oman by the Queen and the Duke of Edinburgh which cost £356,253.
A trip to India by the Prince of Wales and Camilla, whose cost grew by 17% in 2010/11, came in at £298,089. The Queen's total expenditure was £32.1m, down 5.3%.
