eng.economic-order-quantity-extended Calculator
Calculates the Extended EOQ considering quantity discounts, setup costs, and multiple products to find the true minimum total cost order quantity. The classical EOQ ignores quantity discounts — the extended model evaluates total cost at each discount breakpoint to find the global minimum.
Inputs
Annual Demand
Reference formula or conversion factor shown for context.
Order Cost
Reference formula or conversion factor shown for context.
Holding Cost Rate Pct
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
