Frequently Asked Questions
How to add GST to a price?
To add GST, multiply the original cost by the GST percentage and divide by 100. Then add this GST amount to the original cost. Our calculator does this instantly.
How to remove GST from a total amount?
To remove GST (calculate exclusive price), divide the Total Price by (1 + (GST% / 100)). The result is your base price before tax.
What is CGST and SGST?
When selling within the same state in India, the total GST is split equally into Central GST (CGST) and State GST (SGST). For example, an 18% GST becomes 9% CGST and 9% SGST.
