Worry is interest paid on trouble before it falls due.

William Ralph Inge (1860–1954), the Anglican priest and long-serving Dean of St Paul’s Cathedral, became famous in early 20th-century Britain for epigrammatic, morally pointed observations on modern life. The line about worry as “interest paid on trouble before it falls due” reflects Inge’s characteristic habit of translating spiritual and ethical counsel into the language of economics and everyday prudence—an idiom that resonated in an era preoccupied with financial discipline, social change, and the psychological costs of modernity. The saying circulated widely as a standalone aphorism in quotation collections and newspapers, often detached from a specific sermon or essay context.

The metaphor treats worry like paying interest on a debt you may never actually owe. “Trouble” is imagined as a future liability; by worrying in advance, a person incurs real present costs—lost peace, impaired judgment, diminished capacity—without any guarantee the feared event will occur. The aphorism does not deny that planning and prudence are useful; it targets the unproductive, compulsive mental rehearsal of misfortune. Inge’s phrasing implies a moral economy: anxiety is a bad investment, because it yields no protective return and often compounds suffering. The line’s enduring appeal lies in its crisp conversion of an inner habit into a concrete, measurable waste.
