About
Value Added Tax (VAT) or Goods and Services Tax (GST) at a flat 10% rate is a common taxation standard used in major economies such as Australia, South Korea, Vietnam, and Indonesia. While 10% seems mathematically simple, calculating the reverse (extracting the tax from a total price) often leads to errors. A common mistake is simply subtracting 10% from the total, which is mathematically incorrect.
This tool is designed for merchants, freelancers, and travelers who need precise tax figures for invoices or refunds. Whether you need to add tax to a net price or strip the tax from a gross receipt, accuracy is paramount. An error of even a few cents in tax reporting can complicate accounting records. This calculator handles the division logic required for reverse calculation, ensuring compliant financial documentation.
