The additional cost to produce one more unit. Some call it "incremental costing." It is useful in determining whether to offer discounts on incremental sales or sales in larger volumes.

Marginal costing focuses on the extra cost to produce one more unit.

If a company has some idle capacity, knowing the marginal cost can help decide if offering a discount on additional units makes sense, since the fixed costs are already covered, and only the variable costs matter for that decision. It’s like figuring out if a sale at a lower price still benefits the company because the additional contribution margin exceeds any additional costs. It simplifies things when you're trying to maximize profit without getting bogged down by fixed costs that stay the same regardless of output.
