How do roasters determine the price of a bag of coffee?

The retail price of a bag of coffee is rarely a simple markup; it is a complex calculation of risk and operational overhead. At the foundation is the C-market price, the global commodity benchmark for Arabica. While specialty roasters often pay a significant premium above this price to ensure quality and support producer livelihoods, they remain tethered to market volatility. A critical, often overlooked factor is the 'roast loss'—the physical evaporation of moisture and chaff during the roasting process. Because a roaster loses roughly 15% of the green bean's weight, the cost of the raw material must be adjusted upward to reflect the final yield. Beyond the beans, the price must absorb the 'hidden' costs of the supply chain: international freight, import duties, warehousing, and the margins taken by intermediaries or exporters. For the producer, the 'farmgate' price is often the final remnant after these layers of logistics and middleman fees are stripped away. A common misconception is that high retail prices equate to high producer profits; in reality, many roasters operate on razor-thin margins, struggling to balance the rising costs of energy, packaging, and labor against the need to keep coffee accessible to consumers. Transparent roasters now increasingly use 'dynamic pricing' to respond to these fluctuations, moving away from static models that fail to account for the true cost of sustainable production.
