Taxpayer funding for the Prince of Wales increased by 11% in the last financial year, official figures showed on Friday.
Prince Charles also saw his private income from the Duchy of Cornwall increase by 3% and his tax bill increase by nearly £100,000, the annual review released by Clarence House showed.
The figures showed that Charles' income from the taxpayer via grants-in-aid and government departments rose from £1,962,000 to £2,194,000 during 2011/2012, an increase of £232,000.
His funding from the Duchy of Cornwall, the huge estate in southeast England given to the heir to the throne to give them a private income, increased to £18.3 million.
Much of this comes from rent paid on land in the duchy.
Charles' tax bill increased from £4,398,000 to £4,496,000, a rise of £98,000.
Spending on official travel by air and rail came to £1,318,000 -- up £238,000, or 22%, from the previous financial year.
While Charles meets all the official expenditure of the Prince William and his wife as well as Prince Harry, he does not cover their official travel expenses.
Charles and his wife Camilla travelled almost 48,000 miles to and from official engagements at home and abroad.
Official data this month put Britain's 12-month inflation rate at 2.8% in May -- the lowest for more than two years.
