The ka-ching is a generic cash register effect rather than a line from one film or show, built from the bell of a mechanical till and the clink of coins. It became shorthand for money in cartoons, adverts and comedy sketches because listeners instantly understand it without any words. Online, editors reuse the same short clip in memes, TikTok videos and YouTube edits whenever a character earns, spends or wins money. Its brevity and instant recognition keep it useful decades after mechanical registers disappeared from most shops.

The classic cash register ka-ching sound effect, with a sharp drawer ding, used in videos and memes to signal money, a sale or instant profit.
This is the familiar cha-ching of an old-fashioned cash register opening, a short metallic ding followed by the bright jingle of coins and the clatter of the drawer sliding out. It lasts just under three seconds, so it lands instantly without interrupting dialogue or music. Listeners recognise it at once as the sound of money changing hands, which makes it feel satisfying, cheeky and a little triumphant. In a video it turns an ordinary purchase, win or price reveal into a punchline, giving the audience a clear audio cue that something valuable has just happened.
