Compound interest is the eighth wonder of the world.

Quote Investigator finds a close match in an advertisement for The Equity Savings & Loan Company in the Cleveland Plain Dealer, 27 April 1925, p. 26, column 6, without a named speaker. Its history includes credits to Baron Rothschild in 1965 and John D. Rockefeller in 1981. The earliest Einstein credit identified in that investigation is Grace Weinstein’s Courier-Post finance column of 26 November 1988, p. 8C, reporting A. Michael Lipper’s attribution. These are secondary citations, not newspaper pages inspected here. The investigation reports no substantive evidence for Einstein and cites the saying’s placement among the probably-not-Einstein items in Alice Calaprice’s The Ultimate Quotable Einstein (2010), p. 481. This run checked that investigation and the atlas; the atlas holds no Einstein full texts, so no comprehensive search of his writings is claimed. The advertising copywriter and the route to the Einstein credit remain unidentified.

A financial slogan circulated under several famous names before it was credited to Einstein. Quote Investigator traces the comparison with an eighth wonder to an unsigned savings-and-loan advertisement, not to a document by Einstein.

Interest accumulating on earlier interest is presented as an extraordinary financial force.

Einstein’s name supplies scientific authority to an advertising maxim. Neither the maxim nor an investment recommendation is authenticated by that attribution.
