Introduction to Sales Tax and GST Calculations

Sales tax and Goods and Services Tax (GST) are consumption taxes added to the purchase price of goods and services. Businesses, freelancers, and shoppers must calculate these values when creating invoices, preparing tax filings, or checking receipts. Our online Tax / GST Calculator simplifies this process, making conversions fast and precise. Try the calculator at /unitix/finance/tax.

Understanding Tax-Inclusive vs. Tax-Exclusive Prices

A tax-exclusive price is the base cost of a product before taxes are added. A tax-inclusive price is the final amount, which includes the tax. To find the tax-exclusive base price from a tax-inclusive total, use the formula: Base Price = Total Price / (1 + Tax Rate). For example, a $110 total with 10% tax has a base price of $110 / 1.10 = $100.

How to Calculate GST Added or Removed

Adding tax: Tax Amount = Base Price * (Tax Rate / 100), and Total Price = Base Price + Tax Amount. Removing tax: Tax Amount = Total Price - [Total Price / (1 + (Tax Rate / 100))]. These formulas ensure that business owners calculate correct invoicing details and avoid billing mistakes.
