Amazon FBA Profit Calculator - UK

Understand whether an Amazon product actually makes money before you scale it. This downloadable Excel workbook is designed for UK Amazon sellers who want a clearer view of unit economics, margin and advertising headroom without building a spreadsheet from scratch.

What the calculator helps you work out

• Net revenue with VAT-aware inputs
• Landed product cost per unit
• Amazon referral and fulfilment fees
• Profit before advertising
• Profit margin
• Break-even ACOS
• Target ACOS based on the profit you want to keep
• Price scenario comparisons

Why these numbers matter

A product can generate plenty of revenue and still have very little room for advertising. Break-even ACOS shows the approximate ad-cost ratio at which the remaining contribution is consumed. A target ACOS lets you plan below that level so each attributed sale can still leave profit.

The workbook is especially useful when comparing a price change, checking a new product before launch, reviewing a supplier-cost increase or deciding whether a PPC target is realistic.

Built for repeat use

Enter your own selling price, VAT treatment, landed cost and marketplace fees. You can then update the figures whenever Amazon fees, sourcing costs or price change instead of relying on a one-off online calculation.
