A Goods and Services Tax (GST) calculator back-calculates tax inclusive portions or appends tax to base transactions using current standard regional tax slabs.
Input your transaction's base value, select the matching tax slab (such as 5%, 12%, 18%, or 28%), and verify CGST, SGST, and total inclusive results.
To add tax: Amount * (Rate / 100). To back-calculate inclusive tax: Total - (Total * (100 / (100 + Rate))).
Central GST and State GST are applied equally on intra-state billing. For example, an 18% slab splits into 9% CGST and 9% SGST.
