One Price, Many Rates – Cross-Border VAT Checker

For a digital service sold to a consumer in another country, the VAT rate that applies is the CUSTOMER's, not yours - so one advertised price does not produce one net revenue. Advertise 100 across four markets and you keep 78.74 in Hungary at 27 per cent, 80.00 in Denmark at 25, 84.03 in Germany at 19 and 85.47 in Luxembourg at 17: a spread of 6.73, or 8.55 per cent of the smallest, that nobody chose. There are only two coherent strategies and most sellers are in neither: hold ONE GROSS price and your margin drifts, or hold ONE NET price and the customer price drifts instead - the same rate table under 84.03 net asks 106.72 in Hungary and 98.32 in Luxembourg. And a business customer with a valid VAT registration is not a discount but a different sale: under reverse charge no VAT is charged, the buyer accounts for it, and the whole 100 is yours - twenty more than the Danish consumer sale on the identical headline price.

Sellers of courses, downloads and other digital services who advertise one price across borders, and the bookkeepers who are later asked why the same sale produced different revenue in different months.

How it works

  1. Add one row per market with the rate that applies there, and mark the business rows as reverse charge.
  2. Choose what you hold fixed - one gross price or one net price - and enter it.
  3. Read the spread: under one gross price it is your margin moving, under one net price it is the customer price moving.
  4. Compare the last column against your own rate: that is what applying the home rate would have cost on each row.

What you gain

  • Tells you exactly how much it's costing you to apply your own VAT rate to a cross-border digital sale, market by market, instead of one wrong rate applied to everything.

  5. 2. For each market you sell into, type the country name in the 'Market' field and its current VAT rate in the 'Rate' field, then click 'Add Market'. Repeat for every market you want to compare.
  6. 3. Enter your single headline price (the amount you charge customers) in the 'Price' field.
  7. 4. Review the table: for each market, you'll see your net amount after VAT, the customer price, and the exact cost of using the wrong rate for that market.
  8. 5. Toggle between the 'Gross Price' and 'Net Price' strategies to see how your net income or the customer price changes per market, then decide which approach fits your business.

Frequently asked questions

Does this tool store or send my entered market rates or prices anywhere?

No. All data you enter—market names, rates, and prices—is processed locally in your browser. Nothing is uploaded to a server, and no account or tracking is involved.

What exactly does this tool check?

It checks the arithmetic of your cross-border pricing: whether the price you set matches the VAT rate you apply for each market, and shows the financial impact of using an incorrect rate. It does not verify legal VAT registration status or provide official tax advice.

Does it include built-in VAT rates for countries?

No. The tool intentionally has no preloaded rate table. You must enter the current rate for each market yourself, because rates change and a stale built-in rate could mislead you.
