On the high end this translates, roughly, to the equivalent of around $1.85 per pound of green coffee—a pretty good price, to be sure—though it pales in comparison with the $5-7 per pound most roasters are used to paying for Kenyan coffee.
But the average price paid to producers for cherry translates roughly to $1.42 per pound.
The best coops, where premiums of 85 shillings per kg are paid, might retain 5% of the sale, but it’s extremely common for coops to retain roughly 20% from the sale, leaving, in the typical case, just $1.13 per pound to a producer—well below their costs of production, even before the marketing agent’s 1.76%, or milling fees (roughly $70 per metric ton), or out turns, or financing costs that float a producer between harvests. Seriously: Why bother?
