fertilizer phosphate rock consumed cost is the average cost per tonne of purchased and produced phosphate rock consumed in production.

Why it matters

Rock cost helps investors isolate another major feedstock component of phosphate margins. Mosaic reported a 2025 average consumed blended-rock cost of $80 per metric tonne.

Investor caution

Consumed rock cost is not the market value of reserves or a full mining cost measure. It is the issuer's average cost for purchased and produced rock consumed in the period.

Part of the Fertilizer & Nutrient Economics

Connect phosphate and potash realized pricing, sales volumes, production, utilization, raw-material inputs, segment margins, and resource taxes to understand fertilizer producer economics.

How the model fits together
  • Phosphate price, volume, and margin: Finished-product sales volume and average selling price frame phosphate monetization, while the product-specific DAP FOB mine price separates benchmark-product economics from broader mix. Net sales and gross margin show how price and volume convert into segment profitability without assuming one quoted fertilizer price explains all revenue.
  • Phosphate production and input-cost stack: Production volume and operating rate describe supply and capacity use, while consumed ammonia, sulfur, and phosphate-rock costs expose three major input layers. These inputs help explain gross-margin movement but do not form a complete standardized production-cost formula.
  • Potash price, volume, capacity, and resource burden: Sales volume, average finished-product selling price, and MOP FOB mine price connect shipment and product-specific monetization. Production volume and operating rate show supply-side utilization, while gross margin and Canadian resource taxes show how operating economics and resource-based charges convert into segment profitability.
