<P> The Queen has a private income from her personal investment portfolio, though her personal wealth and income are not known . Jock Colville, a former private secretary to the Queen (when she was Princess Elizabeth) and a director of her bank, Coutts, estimated her wealth at £ 2 million in 1971 (the equivalent of about £ 26 million today). An official statement from Buckingham Palace in 1993 called estimates of £ 100 million "grossly overstated". In 2002, she inherited her mother's estate, thought to have been worth £ 70 million (the equivalent of about £ 105 million today). </P> <P> Forbes magazine estimated the Queen's net worth at around $500 million (about £ 325 million) in 2011, while an analysis by the Bloomberg Billionaires Index put it at $425 million (about £ 275 million) in 2015 . In 2012 the Sunday Times estimated the Queen's wealth as being £ 310 million ($504 million), and that year the Queen received a Guinness World Record as Wealthiest Queen . The Sunday Times Rich List 2015 estimated her wealth at £ 340 million, making her the 302nd richest person in the United Kingdom; that was the first year she was not among the Sunday Times Rich List's top 300 most wealthy since the list began in 1989 . She was number one on the list when it began in 1989 . </P> <P> Sandringham House and Balmoral Castle are privately owned by the Queen . </P> <P> The Crown Estate is one of the largest property owners in the United Kingdom, producing £ 211 million for the Treasury in the financial year 2007--8 . and with holdings of £ 7.3 billion in 2011 . The Crown Estate is not the private property of the Monarch . It cannot be sold or owned by the Sovereign in a private capacity, nor do any revenues, or debts, from the estate accrue to her . Instead the Crown Estate is owned by the Crown, a corporation representing the legal embodiment of the State . It is held in trust and governed by Act of Parliament, to which it makes an annual report . Revenue from the Crown Estate is thought to be due to double in real terms between 2010 and 2020 with additional lease revenues deriving from the development of offshore wind farms within Britain's Renewable Energy Zone, the rights of which were granted to the Crown Estate by the Energy Act 2004 . </P>
