Amazon Net PPM Calculator

Calculate your Net Pure Profit Margin — the primary profitability metric Amazon uses to evaluate vendor bottom-line performance.

What is Net PPM?

The Net PPM (also referred to as Procurement Margin) is the main profitability metric that Amazon refers to when evaluating a vendor's bottom-line performance. It considers the average selling price, cost price, and trading terms (Contra-COGS) to determine profitability.

Formula (single ASIN):
Net PPM% = (SP − Cost × (1 − Trade Terms%) + Additional Investments) ÷ SP × 100

Selling Price

Average price Amazon sells your product for, excluding VAT.

Trade Terms (%)

Total Contra-COGS rebate paid by vendor to Amazon, expressed as a % of cost.

Additional Investments

One-off Contra-COGS items not captured in the % trade terms.

What is a good Net PPM?

There is no single benchmark — margins differ by category. Vendor Managers typically target min. 45% in Hardlines and 40% in Consumables. The closer you are to these, the lower the margin pressure from Amazon.
