Known to be one of the richest royals, Prince William, Duke of Cambridge is the eldest son of Prince Charles of Wales and the late Princess Diana of Wales. He has an estimated net worth of $40 million.

William Arthur Philip Louis or commonly known as Prince William, Duke of Cambridge is the second in line to succeed his grandmother, Queen Elizabeth II after his father, Prince Charles of Wales. He is the eldest of two boys and has a younger brother named Prince Harry. His substantial net worth is highly contributed by his various investments income and his inheritance.

Prince William and his younger brother Prince Harry inherited £13 million in trust and after tax from their late mother Princess Diana of Wales. The Duke of Cambridge enjoyed a lavish income since the age of 25 from the £6.5 million capital left to him by his mother, and more from the estate of his great-grandmother, Queen Elizabeth II's mother who died in 2002. These figures highly escalated his already hefty net worth.

The Duke of Cambridge, Prince William also receives a decent wage as an officer in the Royal Air Force. And as a flight lieutenant, he earns £37,170 per year and is also given an allowance from his father's own income form the Duchy of Cornwall Estate. And should his father pre-decease, his net worth will exorbitantly rise when the whole of that income is assumed to him.

Prince William is the second in the line of succession to the thrones of 16 independent sovereign states known as the Commonwealth realms and also the second to the position of the Head of the Commonwealth. In England only, the Duke of Cambridge will be a successor to the Supreme Governor of the Church of England. He was educated in four schools in the United Kingdom and obtained a degree from the University of St. Andrews.

Aside from his continually increasing net worth of $40 million, Prince William is also a delighted family man. The Duke of Cambridge is married to Kate Middleton in April 2011. They had their first born child in July 2013, and named as Prince George of Cambridge. Then on September 8, the British royal family announced that the couple was expecting their second royal baby.
