Which statement accurately distinguishes effective unit price from billed unit price?

• A. They are calculated using the same numerator but different denominators
• B. They are both derived from billed costs per unit
• C. The effective unit price uses the actual cost per pricing quantity, while the billed unit price uses the invoiced cost per pricing quantity
• D. They do not depend on pricing quantity

Answer: (C)

The main idea is understanding how the real cost per unit is determined versus what appears on the invoice. The effective unit price reflects the actual cost per pricing quantity after applying all adjustments that affect value—such as discounts, credits, refunds, and other pricing terms—so it shows what you truly pay per unit in practice. The billed unit price, on the other hand, is the price per pricing quantity that is invoiced, i.e., the amount shown on the bill per unit, before those post-billing adjustments are accounted for. This distinction matters because you can be billed at one per-unit price but receive credits or discounts that change the actual cost you ultimately pay. For example, if you’re invoiced at $0.50 per unit for 5,000 units but receive $200 in credits and $50 in discounts, your effective unit price becomes ($0.50 × 5,000 − $250) / 5,000 = $0.45 per unit, while the billed unit price remains $0.50 on the invoice.
