About the GST Calculator
GST (Goods and Services Tax), known as VAT in many countries, is a consumption tax added to the price of most goods and services. Businesses need to add it to invoices, and buyers often need to work backwards from a final price to find the tax portion.
This calculator does both directions. To add GST, enter the net price and the rate, and it returns the tax amount and the gross (tax-inclusive) total. To remove GST, enter the gross price and rate, and it works out the original net price and the tax that was included. This is handy for invoicing, expense claims, and pricing decisions.
