Product Pricing Calculator (Cost + Margin)

Cost-plus shelf price implied by landed cost plus target gross margin %.

Overview

Use when procurement gave you dependable COGS and you need margin guardrails—not when brand premium is the whole thesis.

When to use this calculator

Rule of thumb

Cost-plus answers “what margin does this COGS support?” Market price still has its own ceiling.

Terms used in this calculator

Gross margin
Sales minus COGS as a percentage of revenue—nothing below gross profit counted here.
AOV
Average order size: slice revenue divided by order count—with tax/shipping counted the same each month.

Calculator

Suggested selling price $42.86

Example calculation

Using the default example values from the JSON seed for this tool:

Product cost
18
Desired gross margin
58

Result: $42.86 (Suggested selling price)

How to interpret this result

Cost-plus price to hit a target gross margin percentage.

Market price may be lower—this answers “what margin does my cost support,” not “what will sell.”

Marketplace fees belong in your cost base when selling on platforms.

Common mistakes

  • Confusing markup percent with gross margin percent.
  • Omitting marketplace take rates in the cost base.
  • Picking margin the market will not support without differentiation.

What to do next

Use margin or break-even unit math when list price must clear operating goals too.

How to improve this result

  • Run lightweight price tests where inventory risk is manageable.
  • Battery-included bundles sometimes lift gross dollars even when SKU count rises.
  • Pressure-test competitors’ offers for shipping and fees—not only list price.

FAQ

Is this GAAP-compliant pricing?
No—it's rough COGS arithmetic. Brand, demand elasticity, competitor promos decide market price.
Where do marketplace fees go?
Add them into landed cost unless you purposely treat them afterward.
What if demand caps price below calculator output?
You either shave margin targets, cut COGS, or reposition the SKU.
Does VAT change this?
Model tax-exclusive or inclusive consistently versus how you merchandise.
Can margin % exceed 95?
The formula clamps—check inputs when math looks impossible.
