The accounts for Clarence House show that public funding for Prince Charles increased by 11.8% during 2011-2012, which means that he spent £20,248,000 in 2011-12, compared with £19,527,000 the year before, an increase of 3.6%.

The figures released by Clarence House include the cost of the Royal wedding and the Duchess of Cambridge’s wardrobe, which seems to have taken toll on his wallet. However, his income from the Duchy of Cornwall and Government grants also increased by the same percentage, from £19.76 million to £20.48 million.

Prince Charles’s contribution to Prince William’s wedding to Kate Middleton was £2,609,000. The Clarence House figures, however, do not break down the costs of the Royal wedding or of the additional cost to the Prince of having the Duchess of Cambridge as an extra member of the Royal family.

Royal aides, however, said the Prince had split the cost of the Royal wedding in April last year with the Queen and the Middleton family, between them paying for the dress, flowers, food, hotel bills and all other miscellaneous family expenses. The total bill that the two families shared is understood to be less than £500,000.

The Prince of Wales pays for all outfits worn by the Duchess of Cambridge on official engagements, which comes out of a budget £2.9 million for the Prince’s private secretaries’ office and the the Office of the Duke and Duchess of Cambridge and Prince Harry. The figure is £100,000 up on the previous year.

The Prince of Wales’s total staff increased by the equivalent of 2.1 more full-time posts, largely because of the extra staff taken on to help the three young members of the family. He now has the equivalent of 134.9 full-time staff, most of whom are back office staff.
