What yield and income range can cinnamon give and how long until first harvest?

After planting, the first bark harvest from coppiced shoots usually comes around the second or third year, then you harvest in cycles as new shoots grow. Dried quill yield builds up over years and varies widely with management, so keep numbers as a range and verify locally. You can earn from more than one product, quill bark, bark chips, and distilled oil from leaves and bark, which spreads income. Prices depend strongly on whether it is true cinnamon thin quill or ordinary cassia bark, with fine quills paying more. Leaf oil gives a side income between bark harvests. Before planning income, confirm a buyer and current rates for your grade, and treat it as a steady long term plantation crop rather than a quick earner.
