Capital Gains is a British radio comedy series which aired originally between 1994 and 1997. There were nine half-hour episodes, broadcast on BBC Radio 4. It starred Peter Jones, and was written by Collin Johnson.

Retired widower Julius Hutch (played by Peter Jones) is beset by bills he cannot pay. Unexpectedly, a large sum of money is paid into his bank account by a foreign merchant bank. When queried, the overseas bank insists that no mistake has been made, so he sets out to spend his windfall of four million pounds.

The episodes of the first series explore the unanticipated problems which arise for both millionaire Julius Hutch and the merchant bank, as a consequence of the unexpected credit transfer, when he attempts to use his windfall to help other people. In the second series, where he accidentally becomes a billionaire, Julius devotes his new found financial muscle to supporting worthwhile ecological causes, with further unexpected consequences.

This is fundamentally a comedy about the small man versus big business. The humour arises because his unexpected wealth enables the little man to give his corporate opponents a good run for their money! The first series deals with Julius Hutch versus a banking corporation, and the second series deals with Hutch taking on a property developer.

Writer Collin Johnson plays various small parts in the episodes throughout both the first and second series. The show is also to some extent a romcom, as both series also explore Hutch's developing romance with a lady named Pauline, who works in the local branch of his High Street bank, played by Celestine Randall. His daughter from his first marriage, Kate, is played by Justine Midda. BBC announcer Brian Perkins plays small parts in some episodes, in addition to his regular announcing duties on the show.
