o-ka-ne, three even beats — the polite お is a full beat and the final e is flat.
okane
Every unit here is the same length. The prefix counts as a full beat, which is the point learners most often miss — お is not an ornament attached to かね but a mora with the same weight as any other in the word.

お金が足りません ends with 足りません, five morae with a tap in the middle and a moraic ん at the close. So the sentence finishes on a full beat of hum, and the ため of the negative gives you three unstressed morae in a row before it.
"oh-KAH-nay" glides the prefix, stresses the middle, and diphthongises the final vowel. Freeze the o, level the beats, and anchor the e. Learners in a hurry also drop the prefix's beat entirely, saying "kane" with an o barely audible in front — that's two beats where there should be three.
