Amazon margin calculator with FBA and VAT
The real margin of a product, with VAT taken out and every cost put in.
Everything is calculated in your browser: nothing you type leaves your computer.
Step 1 of 4 · Your product
Where do you sell? · Required
If you sell under OSS, the VAT is the customer’s country’s.
More product costs (optional)
On the purchase cost.
Fill in the required fields to see the result: retail price incl. VAT, purchase cost, where you sell.
How it calculates
- VAT comes out first: what you charge including VAT is not yours, and the margin is measured on net revenue.
- The referral fee is on the price including VAT, because that is how Amazon calculates it.
- TACOS is advertising spend divided by sales excluding VAT.
- On every return you lose the fulfilment fee and 20 % of the referral fee, plus any product you cannot resell.
- Fixed costs are spread over the units per month you enter.
