Pricing and Product Cost Playbook

Move from a defined product cost to prices, margin targets and discount checks without mixing up the denominator or counting overhead twice.

By PriceAndProfit Editorial Updated

Move from a defined product cost to prices, margin targets and discount checks without mixing up the denominator or counting overhead twice.

Start with the question you need to answer, then choose the tool or worked example that uses the same cost boundary and time period. The guides explain the assumptions behind each calculation. All sample amounts are hypothetical; replace them with your own records before making a plan.

Pricing starts from a cost you can defend. The product cost group covers landed cost, batch yield, direct labor, packaging and overhead allocation, so that the number you mark up includes everything the item really costs to put on the shelf. From there the foundations explain the two ratios every price is quoted in: markup, measured on cost, and margin, measured on price. The profit margin and markup calculators convert between them in both directions, and the chart lists every common step, because quoting one when the other was meant is the most expensive pricing mistake a small business can make.

The next question is how customers respond to a price. Price elasticity of demand summarizes your own price test with the midpoint formula, and the elasticity calculator adds revenue and contribution before and after the change, since a higher price that sells fewer units can still leave more money for fixed costs. The percentage change calculator keeps relative changes and percentage-point changes apart — a margin that moves from 12.5% to 15% rose 2.5 points and 20 percent at the same time.

Discounts get their own group. The discount percentage calculator finds the percentage off, the sale price or the original price behind a sale; the discount margin and stacked discount calculators show what the reduction does to profit, and the guides cover bundles, volume tiers, clearance and buy-one-get-one offers. Every page uses hypothetical numbers only: no market averages, no industry margins. Replace them with your own invoices and sales records before setting a price.
