CM1, CM2, CM3 — what each layer tells you

Three margin stages that pinpoint where profit leaks.

CM1

Product economics

Revenue − COGS − Amazon variable fees

Tells you whether the SKU itself is viable. If CM1 is negative, no amount of optimization saves it — you need a price hike, a cost cut, or to discontinue.

CM2

Marketing economics

CM1 − PPC spend

Tells you whether you can afford to acquire customers. A SKU with healthy CM1 but negative CM2 is burning ad budget to grow unprofitably.

CM3

Operating economics

CM2 − refunds − refund admin − storage

The real bottom line. CM3 is what actually lands in your account after the warehouse, the returns desk, and the storage clock have all taken their cut.

Amazon FBA Profit Margin Calculator: Frequently Asked Questions

What counts as a good margin, what CM1-CM3 mean, and how Nova measures both.

An Amazon FBA profit margin calculator works out the margin percentage on each SKU after every Amazon fee, your PPC spend, COGS, shipping, and returns. The output is a percentage per product — not a fee estimate. Nova's margin calculator runs the math across your entire catalog using live Seller Central data through SP-API.
Median net margins for FBA private label sellers in 2026 land between 15% and 22% across most categories. Supplements, beauty, and pet supplies sit higher (22-32%). Electronics, grocery, and toys sit lower (11-18%). Use the benchmark table on this page to see how your margins compare per category.
Profit is a dollar number ($12.45 per unit). Margin is a percentage (28% on a $44 sale). Both matter: profit dollars determine how much money you keep, margin percentage determines whether the SKU scales. Nova reports both side by side. If you need just the dollars, the Amazon Profit Calculator is the focused tool.
Contribution margins step through the P&L: CM1 = revenue minus COGS and Amazon variable fees, CM2 = CM1 minus PPC spend, CM3 = CM2 minus refunds, refund admin, and storage. Nova exposes all three per SKU so you can see where margin leaks before, during, and after the sale.
Yes. Refunds are deducted as lost revenue, refund admin fees (~$5 per refund) are tracked as costs, and return processing fees apply per category. A SKU with a 12% return rate at $44 average order looks fine on the gross line and ugly on net margin. Nova surfaces that gap.
Nova offers a 14-day free trial with full per-SKU margin calculation across your entire catalog. No credit card required. Paid plans start at $29 per month with annual billing.
Yes. Nova exposes the median and top-quartile net margin for the major Amazon categories (see the benchmark table on this page). You can sort your catalog by % distance from category median to spot which SKUs are underperforming their category, not just your own catalog average.
Yes. Margin calculation handles both FBA and FBM with the right fee logic for each, and covers 21 Amazon marketplaces with automatic currency conversion. You can compare FBA vs FBM margin per SKU or consolidate margins across all markets in one view.
