The Comprehensive Guide to GST Calculation in India: Simplify Your Taxes

The Goods and Services Tax (GST) has transformed the Indian taxation landscape by replacing multiple indirect taxes with a single, unified system. While it simplifies tax collection for the government, it often leaves business owners and consumers scratching their heads over precise calculations. PixelTrim’s GST Calculator is designed to provide instant, error-free results, helping you navigate the complexities of CGST, SGST, and total billing amounts with confidence.

1Add GST vs. Remove GST

Whether you need to calculate the tax on top of a base price (Exclusive) or find the original price from a tax-inclusive total (Inclusive), our tool handles both modes with mathematical precision.

Formulae Used for Calculation

To Add GST (Exclusive):

GST Amount = (Original Cost * GST Rate) / 100
Net Price = Original Cost + GST Amount

To Remove GST (Inclusive):

GST Amount = Total Cost - (Total Cost * (100 / (100 + GST Rate)))
Net Price = Total Cost - GST Amount
