How GST is Calculated?
To **add GST**, the formula is: $Total = Amount + (Amount \times \frac{Rate}{100})$. To **remove GST** from a total price to find the base value, the formula is: $Base = \frac{Total}{1 + \frac{Rate}{100}}$. Our tool handles both automatically, helping you avoid complex manual math during invoicing or tax season.
