  1. Hi Ann,

    Thanks for your interesting question. Oxford Dictionaries spells the word ‘ka-ching’ ( and gives the alternative spelling ‘ker-ching’. It also explains that the word is onomatopoeic as it mimics the sound of a cash register.

    There is an online casino called Kerching, though some may argue that ‘Kerching’ without a hyphen looks more like a verb.

    I think your suggestion of ‘ca ching’ would also be acceptable, though ‘ka ching’ (or ‘ka-ching’) appears to be more common. Another less common US variant is ‘cha-ching’.

    Have any readers heard of other spellings? Let us know in the comments 🙂

    Best wishes,
