Mr Darcy's annual income in Pride and Prejudice amounts to £10,000. In Regency-era England, that made him extraordinarily wealthy and one of the most attractive marriage prospects in the novel.
Darcy's income comes largely from his estate, Pemberley, in Derbyshire. The figure is introduced early through local gossip and is reinforced throughout the story. His wealth gives him independence, extensive property, servants, and a social position above the Bennet family, whose estate produces only about £2,000 a year.
Money is central to Austen's plot. Mrs Bennet is eager to marry her daughters to prosperous men, while Darcy initially believes Elizabeth's family connections and behaviour make a match unsuitable. Elizabeth's eventual acceptance of him matters because she does not marry merely for financial security; she changes her opinion after learning more about his character.
The amount is sometimes confused with Bingley's income, usually given as £4,000 or £5,000 a year, or with the £5,000 dowry associated with Mrs Bennet. Darcy's £10,000 is annual income, not his total fortune.
