How do you calculate retail margin impact?

Subtract delivered cost from net selling price, then divide by the reference price and multiply by 100. With a $39.99 price, $27.40 cost, and a $27.40 reference, that is (39.99 - 27.40) / 27.40 x 100, which the tool reports as a 145.95% figure against the cost-based reference.

Why is the margin over 100%?

Because the reference price entered drives the denominator. When the reference equals delivered cost ($27.40), the result is a markup-on-cost view, which exceeds 100% whenever price more than doubles cost. To get a conventional margin-on-price figure, set the reference to the selling price of $39.99 instead.

What is the difference between margin on price and markup on cost?

Margin on price divides profit by the selling price; markup on cost divides the same profit by cost. The same $12.59 of margin is 31.5% on a $39.99 price but 45.9% on $27.40 of cost — choose the reference deliberately so you know which one you are reporting.

What does the margin gap to target mean?

It is the difference in points between the computed margin and your target. The example shows -105.96 points, which only makes sense because the reference was set to cost; against a sensible price-based target the gap tells you how many points short of plan a SKU is.

What is a good retail margin for consumer durables?

Manufacturer gross margins on durables commonly run 25-40% on net price after delivered cost. Below roughly 20% a SKU rarely covers selling and overhead; above 40% it risks being underpriced for the market or attracting private-label competition.

How do I use the reference price correctly?

Set it to net selling price for a true margin-on-price percentage, to a target price to measure attainment, or to delivered cost only when you intend a markup view. The default of $27.40 produces a markup figure, which is why the percentage runs high.

Retail Margin Impact Calculator

Retail Margin Impact expresses the dollars left after delivered cost as a percentage of a reference selling price, so brand and pricing teams can see how a price, cost, or promo change moves margin. For consumer durables sold through retail, margins are squeezed by freight, retailer allowances, and rising landed cost, and a few points either way decides whether a SKU earns its shelf space. Category managers and finance partners use this to pressure-test list prices, evaluate cost increases, and compare margin against a target benchmark. The reference-price input lets you measure margin against list, a target price, or a competitive anchor rather than only the actual sell price.

What this calculator does

Calculate retail margin impact from sell price, delivered cost, and reference sell price.
checking whether a cost change still fits the retailer or OEM margin target
It computes net margin dollars per unit, then divides by a chosen reference price to express margin as a percent and the gap to target.

Formula used

Net margin dollars per retail unit = net selling price per retail unit - delivered cost per retail unit
Retail margin impact = net margin dollars per retail unit ÷ margin reference selling price × 100

Inputs explained

Net selling price per retail unit:
Delivered cost per retail unit:
Margin reference selling price:

How to use the result

Use it when setting or defending retail prices, evaluating a delivered-cost increase, or comparing SKU margin against a benchmark price.
It works on a single unit's price and cost; it ignores volume mix, retailer-specific allowances, and returns, which can move realized margin well below the headline figure.
