The Prince of Wales received a record total of £21.7m from his private estate and taxpayer funding in the last tax year, official figures have revealed.
Charles's income from the private Duchy of Cornwall combined with money from the public funds increased by almost £1.5m from £20.2m in the previous year.
Nearly all of the Prince's cash came from the Duchy, which raked in £19.5m after a rise of 2.4% or around half a million pounds compared with 2012-13.
The amount of money drawn from the state-funded sovereign grant and government departments for official activities of the Prince and the Duchess of Cornwall nearly doubled compared with the previous year to almost £2.2m.
Courtiers said the rise in the use of public funds was mainly down to the fact that the travel costs of Charles's official engagements had returned to a "more normal" level after being "artificially low" last year when many trips conducted to celebrate the Diamond Jubilee were funded by countries in the Commonwealth realm.
Figures released by Charles's office show that just over £1.3m of public funds were spent on official travel by him and his wife.
A spokesman for the Prince rejected suggestions that the Queen's eldest son lives a "lavish" lifestyle.
"The Prince of Wales lives the life of the heir to the throne," he said.
