How the Price After Tax Calculator works
Adding tax is the straightforward direction, and the thing worth getting right is which price you display. Consumer prices include tax in the UK and EU; US listings exclude it and add at checkout. Showing the wrong one costs conversions.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
How do I add tax to a price?
Multiply by (1 + rate). A £100 net price at 20% VAT becomes £120. At 8.5% US sales tax, a $100 item becomes $108.50 at checkout.
Should my listed prices include tax?
In the UK and EU, consumer-facing prices must include VAT. In the US, listings conventionally exclude sales tax and add it at checkout based on the buyer's location. B2B pricing usually excludes tax in both.
What if I sell to multiple countries?
Most platforms can display tax-inclusive prices by region. Where they cannot, price for the market whose rules are strictest and make the treatment explicit — surprise tax at checkout is a major cause of abandonment.
Do I charge tax if I am not registered?
No. Below the registration threshold you neither charge nor reclaim it. Charging tax you are not registered to collect is a serious problem, so confirm your status before adding it.
