Where Will and Kate Get Their Money

William is definitely not one of the 'idle rich'.

He works as a helicopter pilot with the East Anglian Air Ambulance, earning a salary of £40,000 a year.

When Princess Diana died, she left her sons a trust worth an estimated £20 million. William has had full access to his half since he turned 30. Before then, he could live off the investment income, estimated by Forbes to be just under £290,000 a year.

Diana also left her sons personal documents, photographs, home movies, priceless jewellery and dresses, such as her famous wedding dress. These could bring in a princely sum at auction or through exhibits.

Before her death, the Queen Mother created a trust fund for her great-grandchildren.

Will was to receive a reported £1.9 million on his 21st birthday. He and brother Harry will also share about £7.7 million, when they turn 40.

Prince Charles pays the salaries of the couple's staff and some of the costs of their official duties. The Duchy of Cornwall, Prince Charles' portfolio of properties, is worth about £763 million.

Among the things Prince Charles pays for from his 'household budget' are Kate's clothes for her royal duties. When Prince Charles becomes king, Will, as the eldest son of the reigning monarch, will become the next Duke of Cornwall and will be able to live off the Duchy's profits.

Parliament grants the Queen £37.9 million every year. She is notoriously frugal with her money but paid for the renovation of Kensington Palace Apartment 1A, Will and Kate's London residence.

The Queen also made Anmer Hall, a stately country home near Sandringham, available for the couple to live in.

While she may not actually own Buckingham Palace or the Crown Jewels, Queen Elizabeth is a very wealthy woman. Forbes estimates her personal fortune, which includes Balmoral and Sandringham, a valuable stamp collection, jewellery, horses and art, at about £320 million.

The Queen, now 88, is sure to leave each of her grandchildren a generous inheritance when she dies. When Will becomes king, he will receive the Duchy of Lancaster, which earns an income for the reigning monarch. It's currently worth about £429 million.

Kate may be a commoner but she's definitely not from a poor family.

‪Michael and Carole‬ Middleton are worth an estimated £32 million, according to The Richest. They made their fortune through Party Pieces, an online party business.
