Americans pronounce monetary as MAH-nuh-tair-ee (/ˈmɑnəˌɾɛri/). Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The federal reserve signaled a shift in monetary policy".
Record yourself saying "monetary" and play it back. The mic stays on your device — nothing's uploaded.

The textbook way isn't wrong — it's just not how anyone actually says it.
Stress falls on the first syllable, not the others. Stretch MAH — keep everything else short and quick.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.
