One Book, Seven Currencies: Tracking KDP Profit Across US, UK, DE, FR, ES, IT & JP

Sell one book across Amazon's marketplaces and you are not running one business — you are running seven. Royalties accrue in dollars, pounds, euros, and yen. Ad accounts are billed region by region, some with tax on top. Nobody consolidates any of it. So the author who "adds up the dashboards" to check profitability is quietly comparing numbers that are not in the same currency, not net of the same taxes, and not measuring the same thing. A title that is clearly winning in the US can be losing money in Germany — and the blended dashboard total hides it completely.

Three places money quietly disappears

Between the revenue Amazon reports and the money that reaches your bank, three layers eat your margin — and none of them show up in the ad console.

• Withholding tax on royalties. Depending on your country's tax treaty with the US, KDP can withhold up to 30% of your royalties before paying you. A $1,000 royalty month can arrive as $700.
• VAT/GST on ad spend. In the UK, the EU, and other regions, your Amazon Ads bill is charged with tax on top — 20% in the UK, 19% in Germany, 20% in France. A "£500" ad month is really £600 out of your account. US ad spend generally carries no VAT, so the same campaign has a different true cost in every marketplace.
• Currency conversion. Amazon pays each marketplace in its local currency. Converting euros or yen into your home currency typically loses 2–4% at the bank, plus payment thresholds that hold small balances for months.

Why you can't just add up the dashboards

Stack those layers together and the naive total is simply wrong. Watch the same book in two marketplaces, before and after the hidden costs:

Both marketplaces looked identical on the dashboard: +240 each. In reality the German market delivered less than half the profit once tax and FX were applied — and a slightly worse ad month there would tip it negative while the dashboard still showed a comfortable surplus. Add the two "profits" together as 480 and you have a number that means nothing.

What a real consolidated P&L looks like

To compare marketplaces honestly, every figure has to be normalised to the same basis before you add anything:

1. Convert every amount to one reporting currency at real rates, so dollars, euros, and yen are finally comparable.
2. Count royalties net of withholding tax, using your actual treaty rate — not the gross number KDP displays.
3. Count ad spend tax-inclusive, applying each marketplace's VAT/GST rate to the console figure.
4. Then, and only then, sum to a per-book and account-wide net profit per book.

Do this and marketplaces you assumed were equal separate into clear winners and quiet losers — and you can shift budget toward the regions that actually pay.

The KENP wrinkle, everywhere at once

Kindle Unlimited runs in multiple marketplaces too, each with its own Global Fund and per-page rate in local currency. So the page reads that rescue a campaign from a scary ACOS also need converting and consolidating before they can join your profit picture. It is the same reconciliation problem, multiplied by every marketplace you sell in.

Where TrueRoyalties fits

This is the mess TrueRoyalties was built to erase. It pulls royalties and KENP from every KDP marketplace and spend from every Amazon Ads account, applies your withholding rate and each region's ad VAT, converts everything into a single currency, and presents one consolidated, tax-aware profit view — per book and overall. No more comparing a dollar dashboard to a euro dashboard and hoping. Just the one number that survives translation across every marketplace: Net Profit = Royalties − Ad Spend.
